ThinkBook Plus G5 External Storage

Leave a comment

I’ve been messing about with an interesting (and covetable) Lenovo hybrid laptop lately. it’s got an x86 PC for the keyboard deck, and a plug-in 15″ Android tablet that also doubles as a laptop display when docked with that deck. I plugged my fastest external USB storage devices into the free TB4/USB4 rated USB-C port and ran CrystalDiskMark. That gives me some basis to talk about ThinkBook Plus G5 external storage. I’m checking outUSB4 NVMe, TB4 NVMe, USB3.0 Msata, and USB 3.0 HDD storage devices.

ThinkBook Plus G5 External Storage Capability

I’m running CrystalDiskMark version 8.0.6 through its standard testing paces to see how these various devices all compare, in the same USB-C port and using the same USB4 rated cable. So far, what I’ve seeing is not bad, but not on par with other high-end Lenovo laptops or mini-desktops. (FWIW, I’ve also noticed that Snapdragon X Copilot+ PCs offer excellent USB-C USB4/TB performance, but only 5 Gbps capability on their built-in USB-A 3.2 Gen 1 ports.)

The internal SSD in the ThinkBook Plus G5 (I’ll abbreviate that as TB5 for brevity) gets reasonable performance. It’s a Samsung OEM NVMe MZAL81T0HDLB-00BL2 (vintage 2022, Gen4x4 M.2, middling performance). It does pretty well on large data transfers (~6GB read/4.7GB write queue depth 8; 3GB read/2.9GB write queue depth 1). On Random 4K reads, it’s somewhat less thrilling: 337.7MB read/264.5MB write queue depth 32; 60 MB read/113MB write queue depth 1). Those CrystalDiskMark (CDM) results provide the lead-in graphic for this story.

When I shift to external storage via USB, the story gets darker quickly:


Type   1TibRWQ8  1TibRWQ1   4KRWQ32  4KRWQ1
USB4   3062/447  1692/521   337/8    11/4
TB4    2615/530  2211/491   345/14   62/10
mSATA  465/331   436/121    138/20   23/2
HDD    118/117   117/52     1/1      0.4/0.4

On the whole, I’d have to say that I/O performance with external storage is NOT a strong suit for the otherwise interesting and occasionally excellent/amazing TB5. I see at least 15% better performance across the board for all those devices on the 2022 vintage Lenovo ThinkPad P16 Gen 1 Mobile Workstation and the 2023 vintage Lenovo ThinkStation P3 Ultra mini-Workstation. For example, here are the internal drive results from the 2022 vintage P16:

The Internal NVMe on the P16 is mostly 15+% faster across the board. Only 4KR/QD=1 is slightly less.

Note: the P16’s internal drive is a WD SN810 2TB NVMe (PCIe Gen4 x4 drive with performance nearly equal to the TB5’s Samsung OEM drive).

Space and Cost Are at a Premium, So…

In a hybrid device like the TB5, I have to believe that space and device costs are important elements to control. My best guess is that Lenovo went with more compact and possibly lower-cost USB circuitry than they put into those other two devices. Then again, the internal SSD could be slower than those used in the other devices as well. Both will impact overall I/O performance.

On the other hand, as I use the TB5 for surfing the web, doing workaday tasks, installing and running all kinds of software and tests, and more, I’ve not really noticed I/O as a bottleneck. Perception is vital to user experience, so these numbers I’ve shared may paint this fascinating two-in-one less positively than they should. Bear that in mind as you consider “buying this dream.” I’m reading that MSRP will be right around $2K for a 22-core Ultra 7-155H, 32GB, 1TB SSD model. It just may be worth it.

Next up: I’m going to take the Android tablet for a ride on its own, to see how it does as a detached tablet. Stay tuned!

Intake: Lenovo ThinkBook Plus G5

Leave a comment

OK then, I’ve gotten far enough past my holiday backlog to take a first look at an odd but intriguing new hybrid laptop PC. On intake, Lenovo ThinkBook Plus G5 shows itself to be an interesting and powerful performer. The unit is actually two PCs: an Intel x86 PC embedded inside the keyboard deck, with a detachable Android tablet that serves as a Windows monitor when docked with the deck. Good stuff! You can see the tablet in position for docking above the deck in the lead-in graphic (image courtesy of Lenovo).

Observations During Intake:
Lenovo ThinkBook Plus G5

I knew this was going to be interesting when I opened the shipping carton and saw it contained two boxes. As you might guess: one for the Android tablet, the other for the x86 Intel deck. What you might not guess is the Matrioshka-like box within a box for those inner boxes themselves — one each for tablet and deck. Indeed, everything used for shipping these units (and other new items from Lenovo since 2012, believe it or not) is made of paper. Over the past dozen years in fact, I’ve watched the plastic content drop to zero. They even use paper-covered twist ties (when they use them at all). So kudos to Lenovo for easy-to-unpack, sustainable packaging.

Deck spes

Here are the specifications for the deck in this paired hybrid laptop whose full official product name is ThinkBook Plus Gen 5 Hybrid (14″ Intel) Station & Tablet:

CPU: Intel Core Ultra 7 155H (16 Cores, 22 logical processors)
Memory: 32 GB dual-channel LPDDRX5 7467 MHz RAM
Storage: 1 TB M.2 PCIe Gen4 NVMe SSD (Samsung OEM)
Ports: 2xUSB4 Thunderbolt4 USB-C ports on deck,
1 RCA audio mini-jack
Network: Intel Wi-Fi 6E AX211 160MHz

Tablet Specs

Here are the specs for the tablet side of this duo:

CPU: Qualcomm Snapdragon 8+ Gen 1 (8 Cores)
Graphics: Qualcomm Adreno GPU
Display: 14″ 2.8K (2880×1800) OLED multi-touch
Memory: 128GB LPDDR5x (soldered, no upgrade)
Storage: 256GB UFS 3.1 on tablet motherboard
Sensors: Accelerometer, ambient light, color, gyroscope, hall, ToF, and e-compass

I can’t say much about battery life just yet. The tablet has a built-in Li-polymer 38.7Wh battery with life estimates from 6.83 hours (web browsing) to 52.14 hours (local audio playback). Thurrott sez it gets 4.5 hours using it as a normal Windows laptop. He also says the 100W brick charges the deck’s 75 Wh battery to “almost full capacity in about an hour.” For now, it tells me the combo unit is intended as a desktop replacement, while the tablet is more prepared for extended untethered use. I’ll learn more later…

Initial Start-up and Setup

I had to wait for the deck and tablet to garner minimal charges before I was able to start the hybrid pair up into Windows for the first time. No biggie, but Lenovo usually sends units out fully charged. It took patience, but was easily overcome.

Lenovo Vantage hit a new update record when I used it to check for outstanding items: 11 on the first try, 2 on the second try. I was pleased the unit shipped with Windows 11 Pro installed, and amused to see it running Version 23H2 (Build 22631.4541 after all updates were applied). This process took the better part of an hour to work through, with a handful of restarts along the way.

As Windows laptops go, this one’s pretty peachy. It runs nearly as fast as the P16 Gen 1 Mobile Workstation (with its 24 core i9-12950HX CPU and double the RAM). I’m still in the process of getting all the apps installed, Windows Terminal customized, and working through the usual intake and setup drill. But so far, you can color me impressed!

Tablet Remains Terra Incognito

Last night, I pulled the tablet off the laptop to show my wife it displayed an Android screen when disconnected. Pretty colorful, too. But that’s as far as I’ve gotten with that half of this dynamic device duo. I plan to read some manuals, and fool around, over the weekend. More to follow on that front next week.

Pros and Cons So Far

There’s a lot to like about this dual unit. It’s sturdy (made of machined aluminum throughout with a matte grey silver finish), attractive, and a pleasure to use. The tablet display pops with color and text is rendered crisply and legibly. So far, I love the concept of running the tablet separately but I haven’t put that to the test yet, so I can say if I love the execution or the actual use.

There are a few cons about the ThinkBook Plus G5, though, but nothing too onerous or serious:

1. The combined weight of the units is ~3.9 lbs (2.14 deck & 1.73 tablet). That’s heavier than I’m used to for a modern laptop.
2. This sucker is kinda costly, with an MSRP of US$1,999 for the current configuration. It also included a US$38 accessory called the Lenovo Tab Pen Plus.
3. Despite its 160MHz rated Wi-Fi adapter, I couldn’t get it to work at 160MHz with my ASUS AX6000 router. Works fine at 802.11ac levels, though. That said, it runs at 380-500 Mbps on my LAN.
4. With only two usable USB-C ports and no USB-A ports, users will have to carry a hub or use a dock if they want to attach more than 1 or 2 devices.

All in all, it’s a pretty nifty machine. I look forward to putting it through its paces and seeing what more (and what else) it can do. Stay tuned.

Lenovo ThinkStation P3 Ultra Intake

4 Comments

When Lenovo asked me if I’d like to review another one of their well-engineered SFF PCs last week, my immediate reply was “Heck yeah!” The ThinkStation P3 Ultra Small Form Factor Workstation showed up lateThursday. I got to unboxing and setup over the weekend. So far, it’s been a gas, but a bit of a mixed blessing. Let me explain…

Working Thru Lenovo ThinkStation P3 Ultra Intake

I’ve looked at a couple of recent Copilot+ PCs (Lenovo Yoga Slim 7x and ThinkPad T14s) and a couple of other late 2023/early 2024 laptops in the last 12 months. All of them included plastic-free packaging.  Thus, I was SHOCKED to see plastic bags and plastic twist ties in the P360 Ultra packing materials. That was my first clue this is no bleeding edge PC.

My next big clue came when I opened Settings > Bluetooth & Devices > USB and found no USB4 hubs in evidence. In fact, I had to revert to the old Thunderbolt Control Center (TBCC) to see (some of) my faster USB4/Thunderbolt4 devices and connections. Here’s a screencap:

My newest USB4 NVMe enclosures didn’t show up in TBCC, but the 2022 Acasis model did. Go figure!

I have two newer USB4/TB4 NVMe enclosures (Konyead and Maiwo models) that don’t pop up in TBCC. Because they DO show up on the Copilot+ PCs in the USB4 hierarchy, and I can observe they run at higher speeds, I know they’re working OK. But it’s a bit distressing to lack the level of insight and monitoring I get on USB4-capable Windows 11 PCs.

Speeds, Feeds, and So Forth…

These are, however, pretty darn minor as quibbles go. The P3 Ultra is a speedy and capable PC in a nicely compact package. Indeed, as equipped, it retails for about US$2,500 so it’s no lightweight by any estimation. Here’s what’s inside:

  • CPU: Intel 13th-Gen/Raptor Lake 19-13900 (24 cores)
  • RAM: 64 GB (2x32GB DDR5-5600 Hynix)
  • OS: Windows 11 Pro Version 23H2
  • Graphics: Intel UHD Graphics 770/NVIDIA RTX A2000 12GB
  • Networking: Intel I225-LM 2.5 GbE and I210 GbE,  Intel AX211 Wi-Fi6 adapter (with external antenna)
  • Storage: Hynix OEM PCIe x4/Gen4 2TiB NVMe SSD, 1 open M.2 slot, 1 open SATA slot
  • USB ports: 2xUSB-C/USB4-TB4 40 Gbps front, 2xUSB-A 3.2 back, 1 front
  • 3xDisplayPort 1.2 ports (both miniDP and full-sized)
  • PSU: External 300W power brick

This is a nicely-equipped PC for sure, but its lack of Wi-Fi7, USB4, older DP version (1.2) and packing materials that include a tiny bit of plastic all speak to 2023 standards. And indeed, a quick check on the release date says May 2023. It is what it is, and what it is is a fast and fairly powerful mini workstation. I’m glad to have it here.

Set-up and Intake Process

Once I got the P3 Ultra plugged in and attached mouse and keyboard (included) and wired into a Lenovo ThinkVision P27u-20 monitor the OS came right up into a generic Admin user account. As is my wont I set up my usual MSA as another Admin account. Then came a slew of upgrades and updates, starting with this handful of Quality updates:

Then came a number (8) of driver updates:

I also perforce picked up the latest MSRT when I got the latest quality update. The whole process took about 15 minutes, including reboot and restart. Interestingly, Lenovo Vantage didn’t find anything new to add to the July 2 Intel Chipset update. But it just now found a new chipset and graphics driver so I’m installing them now (total time: 2 minutes plus reboot/under 3 minutes to get back via RDP).

Then I used PatchMyPC Home Updater plus a few manual installs to add 7-Zip, 8GadgetPack, Advanced IP Scanner v2, CPU-Z, CrystalDiskInfo, CrystalDiskMark 8, Everything, FileZilla, Chrome, HWiNFO64, Intel DSA, NotePad++, the NVIDIA (beta) app, Revo Uninstaller, and WizTree to my runtime environment. That took 15-20 minutes in all. I still have to install Macrium Reflect for backup, but I’m mostly ready to start working with and testing this PC. More will come soon, but what I see so far is fast and capable.

Lenovo Yoga Slim 7 Gets Accolades

Leave a comment

For over a week now (11 days, actually) it’s been my pleasure to work with the excellent and affordable Lenovo Yoga Slim 7 Copilot+ PC. It’s got modest stats — Snapdragon X Elite X1E78100, 16 GB RAM, 512GB SSD and a gorgeous OLED display — but a modest MSRP of ~US$1,200. And it’s got Copilot support with a 45 TOPs NPU to take advantage of AI capabilities and planned support features. In short, it’s a pretty great ultrabook-style laptop with usable features and capabilities at the low end of the price spectrum for such devices.

Who Says Lenovo Yoga Slim 7 Gets Accolades?

Lots of reviewers give it high ratings or rankings. Paul Thurrott has written about it 4 times in the last week with positive things to say in every piece. WindowsCentral says it has the “best bright screen,” and one of its other reviewers says it “may be his favorite Windows laptop ever.” Online reviews abound with phrases like:

  • Great bang for the buck
  • Hidden Gem
  • Everything you Need
  • Amazing Display + Battery Life
  • A solid graphic design laptop

Indeed, all of these breathless exhortations match my own recent experience working with the unit myself. I’ve reviewed a LOT of Lenovo laptops (probably around 100 or so, over the past 15 years) and this one is in my personal top 3, along with the still-amazing X12 Hybrid Tablet and the equally killer P16 (Gen 1) Mobile Workstation.

Still Looking for a Killer Justification

Because MS pulled its Recall feature owing to security concerns, I’m still trying to decide if the pre-loaded AI models on the Yoga Slim 7 –which account for  fair amount of its 100+GB on-disk footprint when delivered — provide enough added value to further tip purchase decisions in its favor. That’s nothing on MS or Lenovo: I need to learn enough to figure out how to use them and what they’re good for. So it’s on me!

But as a new laptop, I think the Yoga Slim 7 represents a great value for the money (I’ve seen prices — e.g. Best Buy — at $100 lower than Lenovo MSRP). So far it’s handled everything I’ve thrown at it with grace and dispatch. It won’t run Google Drive (no ARM support yet) but seems to run pretty much everything else. If I needed to buy a laptop right now, I’d be happy to buy this one. It’s a good value and should have enough oomph to carry users for 3-5 years with ease. Given AI (and Hyper-V/VM) appetites for RAM and storage, you might want to opt in for the 32GB RAM and 1 TB SSD model. That said, I don’t see it for sale in the Lenovo Store just yet…

Windows 11 on ARM IS Different

Leave a comment

Gadzooks! It’s been an interesting last few days. Friday morning, a Snapdragon X Elite-based Copilot+ PC — the nifty Lenovo Yoga Slim 7 — showed up here at Chez Tittel. I’ve been working and messing around with it pretty much ever since, amidst occasional bouts of paying work. Among my observations so far: Windows 11 on ARM is different from its x86 counterpart. Let me explain…

Why Say: Windows 11 on ARM IS Different

Take a look at the intro screencap. I ran it on the Copilot+ PC immediately after updating that unit from WU. On an x86 PC, the progress bar would count to 10% on one line, then it would count to 100% on a second line before completing the component cleanup directive (middle portion of the image). On ARM, no such shenanigans. In general also, this also PC runs faster than x86 for all these intense DISM commands. But there’s more…

After I got going on this PC Friday afternoon, I tried to uninstall McAfee (one of the few bits of junk/gunk Lenovo throws onto its laptops these days). The uninstaller got to 10% and sat there . . . and sat there . . . and sat there FOREVER. At the time time, the Start menu became unresponsive, apps and applications wouldn’t load, and the machine in general ran like a wounded animal by fits and starts. WTF?

Then it dawned on me: I checked WU and, sure enough, a CU update for the .NET Framework (KB5037589) had been installed, and a restart was pending. I killed everything else, then restarted the unit to complete that update. Immediately afterward, the PC returned to speedy, fluent operation. I haven’t had a noticeable glitch since then.

My conclusion: if an update on an ARM PC requires a restart, it’s best done immediately after the update finishes installing. I could’ve saved myself oodles of wasted time and wondering what was wrong with the Yoga Slim 7 if I’d done that myself yesterday. Now I know: it won’t happen again. That’s a very different story on x86, where I’ve gotten away with postponing restarts for days sometimes…

More to Come, I’m Sure…

But I’m just getting started with this new AI-enabled PC. I’m sure I’ll have lots more to report in the days and weeks ahead. This morning, I started playing with Copilot and observed that it runs faster, but doesn’t seem any better-equipped to read my mind properly than it was before. I’m still learning how to build queries so I can get good answers. I’ve also tried out the AI-enabled version of MS Paint with varying degrees of success.

Stay tuned as I get myself oriented, and start learning how to take proper advantage of a Copilot+ PC. It should be interesting!

Yoga Copilot+ PC Pops In Unexpectedly

Leave a comment

When I sent an email to the Lenovo Reviews team earlier this week, I asked that they send me a Copilot+ PC at their earliest convenience. When “the Boss” told me “You have a package” this morning, I had no idea what it might be. But gosh: it’s  a brand-spanking-new Yoga Lenovo Yoga Slim 7 14Q8X9. It’s still booting — during which it clearly recognized itself as a Copilot+ PC — so I can’t even say what’s under the hood just yet. But when a Yoga Copilot+ PC pops in unexpectedly, I’m happy to work through its OOBE and setup stuff. Wow!

Yoga Copilot+ PC Pops In Unexpectedly, Things Get Fun!

OK, I got far enough into booting that I can say a little about what’s what (thanks to System Information in the running OS):

  • Snapdragon X1E78100 CPU
  • 3K (2944×1840) OLED display (great, sharp colors)
  • 16 GB RAM
  • 512 GB SSD
  • Windows 11 Home (!)
  • All 3 USB ports (2 left, 1 right) are USB 40Gbps

From what I can see about pricing on the product page, my unit as configured would cost US$1,200.00 (in round numbers). If I were buying one, I’d definitely spend the US$69 to bump it up to 32GB RAM, and US$45 to take it up to a 1TB SSD.

Apparently, I’ve got a lot of work to do on intake. I’ll be upgrading this to Windows 11 Pro, mostly so I can use RDP to get into the machine from my dual-screen desktop.

First Impressions

As with the Lenovo Yoga Pro 9i that preceded it, the Yoga Slim 7 shows up in plastic-free packaging. It took less than a minute to unbox and put things together. Interestingly, the unit wouldn’t boot until I plugged the brick into an AC outlet, and hooked it up. Normally, Lenovo sends review units out with a full charge. But not this time — probably because they put it in the pipeline for shipping as soon as I requested the unit on Wednesday. Again: I’m stunned and thankful.

The unit lives up to its slim moniker, but feels sturdy and high-quality in the hand. According to its product page, it weighs 2.82.lbs/1.28kg:  but it feels both light and powerful. The deck and outer surfaces are all a wonderful dark shade of midnight blue.

An Upgrade Wrinkle…

Interestingly, I couldn’t use a MAK Windows 11 Pro key to upgrade the unit (maybe that one doesn’t include ARM coverage?). I had to burn one of my MVP Windows 11 Pro retail licenses to get the upgrade through the Activation center in Settings. It shows the same screen as when using Recovery to perform an in-place repair install (unsurprisingly). I’ll report back in when this finishes.

Soon, I’ll also be able to report in on the Yoga Slim 7’s Snapdragon specific AI-based Copilot features. That should be a total gas. Right now, I’m still in the intake process, getting ready to put this PC through its paces. Stay tuned!

My next move will be to box up and send back the truly terrific Lenovo Yoga Pro 9i I’ve had since late April. It’s been a great (and powerful) PC especially for VMs in Hyper-V. I’ll be sorry to see it go. But I promised to send it back as soon as another USB4 capable unit showed up here at Chez Tittel. That means an outing to the FedEx storefront at 183A and 1431 later this afternoon. Good-oh!

Comparing USB4 40 vs 20 Gbps

Leave a comment

My rationale for keeping the terrific Lenovo Yoga Pro 9i for a couple of extra weeks comes from a recently acquired Maiwo 40 Gbps USB4 NVMe enclosure. Handily, the 9i has two USB-C ports side-by-side. One is rated 40 Gbps, the other 20 Gbps. The lead-in graphic has me comparing USB4 40 vs 20 Gbps via CrystalDiskMark. As you can see, the port speed makes a difference, especially for large block transfers (upper half of each chart).

Comparing USB4 40 vs 20 Gbps: What’s the Diff?

As you can see in the lead-in graphic, the 40Gbps port is faster than its 20Gbps counterpart in 3 out of 4 rows in CrystalDiskMark. It’s double or better for the top 2 rows which involve large (1MB) block transfers. It’s also faster on random writes of 4K blocks, and slightly slower in random reads of such blocks.

Copilot explains these differences as follows (and I am convinced it’s correct because of fundamental principles involved):

  • Large reads and writes benefit more from the higher speed . . . because they involve continuous data transfer.
  • Smaller reads and writes may not fully utilize the increased speed, resulting in smaller differences.

Indeed it makes sense to me that the 4K transfers (which means such reads involve 8 512-byte sectors per read or write) would be less sensitive to bandwidth than 1 MB transfers (2,048 512-byte sectors per read or write, as in 211 transfers overall for each such operation). There’s a lot more time for the speed difference to manifest for those larger transfers. The smaller ones are so fast, the channel speed differences don’t matter much (or at all).

Comparing Backup Times

But CrystalDiskMark is a synthetic benchmark, so it’s not entirely clear how accurately it reflects speeds when performing various operations. For me, the ultimate test of an external USB storage device is how fast it can complete an image backup of the PC’s boot/system drive. Indeed backup and restore top my list of “things to use external USB storage for.” So let’s compare those numbers, shall we?

Because my fave backup tool — namely, Macrium Reflect — is no longer free, I installed and used EaseUS ToDo Backup Free instead. I ran two complete backups with the same drive, same cable: one thru the 40Gbps port, the other thru the 20 Gbps port. File Explorer reports the size of the C: partition at 73GB; other partitions on that drive weigh in at over 1GB total (interestingly, EaseUS reports backup size at 119.5GB). I used 120GB as my backup size in the following table.  I also checked Settings | Bluetooth & devices | USB | USB4 hubs and devices to confirm that the first timing used the 40Gbps and the second the 20Gbps USB-C ports.

Port    Total Time    GB/min
40Gbps  03:22 (202)   35.64
20Gbps  05:11 (311)   23.15

As you might expect the difference is not linear. The 40Gbps backup averages about 35% faster, not 100% as a purely linear ratio would dictate. Even so, this saves 109 seconds (01:49) on backup time. As the backups get bigger, the gap widens. Very interesting!

More for Less

Right now a 40Gbps NVMe enclosure (with cooling fan) costs  (US$70) about fifty bucks LESS than what I paid for a 20Gbps device two years ago (sans fan). Thus, I’d say the difference was definitely worth it.

If you’re buying new, there’s no reason to consider an older 20Gbps device. The real question for those with PCs or laptops 2 years old or older is: does this speed difference justify buying a newer computer? Only you can decide for yourself. For me, it’s pretty compelling . . . but for now, I’m using a loaner unit from Lenovo to measure this capability. I haven’t shelled out to buy a brand-new machine with my own cash recently, either. But I’m thinking about it, hard.

USB4 Means Yoga Pro 9 Stays On

Leave a comment

I have to apologize to the review team at Lenovo. I’d told them I’d be sending back their splendid Yoga Pro 9(i) last Friday. Then I got an assignment from AskWoody to write about external, USB-attached NVMe (and other SSD) storage devices. So of course I had to a buy a current-gen 40 Gbps USB4 drive enclosure. Also, its inbuilt USB4 means Yoga Pro 9 stays on here at Chez Tittel while testing is underway. Sorry, Jeff and Amanda: I need to keep this beast a bit longer…

Why USB4 Means Yoga Pro 9 Stays On

Short answer: it’s my only PC/laptop with USB4 capability. And I want to research and write about same. And on the Yoga Pro 9i the first thing I observe is that while it has two USB-C ports, only one of them supports 40 Gbps throughput (the other is USB-C 3.2 and tops out at half that). This makes a big difference in read/write speeds. Ditto for cables: for best results you need a cable marked 40 Gbps or Thunderbolt 4, too. The device info for the MAIWO 40Gbps enclosure shows what needs to appear for fastest I/O:

USB4 Means Yoga Pro 9 Stays On.Settings-USBdevinfo

The salient info is at the bottom: 40Gbps. It also detects a Gen3 NVMe SSD.

Over the next 10 days or so, I’ll be comparing enclosures, drives, and cables with related measurements. This should be interesting. But for now, let me observe that I paid US$70 for a 40Gbps NVMe enclosure yesterday. When I bought the previous generation (20Gbps) enclosures, the cheapest ones cost US$120 or thereabouts. It’s good that the technology is getting both faster and cheaper. I’m very interested to see how quickly Macrium Reflect can back up the Yoga Pro 9i with a fast SSD and this fast enclosure. Should be fun!

Top of the Heap? You tell me…

FWIW, Cale Hunt over at WindowsCentral just anointed the Lenovo Yoga 9i as the #1 best laptop for 2024. I’ve found it to be pretty stellar in my 5 weeks working with it so far. It’s been great at handling complex programs, lots of VMs, and both compute- and graphics-intensive workloads. Too bad it came out before Copilot + PC requirements were known. It’s close, but not quite at that level. Sigh.

Yoga Pro 9i Shows Incredible SSD Speed Variations

Leave a comment

I’m digging into the behaviors of the svelte and powerful Yoga Pro 9i I’ve had for two weeks today. It’s a speedy and powerful beast of a laptop. It’s half the thickness (30.23mm/1.2″ vs 19.4mm/0.77″ on average) and ¾ the weight (2.95kg/6.5 lbs vs 2.23kg/4.9 lbs) of the Lenovo P16 Mobile Workstation (Gen1). But it’s either on par with or faster than that bigger beast of a desktop replacement. All this said, though, running various NVMe drives and enclosures, I’ve observed that the Yoga Pro 9i shows incredible SSD speed variations.

Why Say: Yoga Pro 9i Shows Incredible SSD Speed Variations

The first set of CrystalDiskMark (CDM) results for the Yoga Pro 9i serve as the lead graphic up top here. These come from the internal SSD inside the unit’s M.2 drive slot. According to Device Manager that drive is an SKHynix_HFS001TEJ9X115N (1TB PCIe x4 NVMe 1.4). Those are pretty respectable results, and serve as a point of reference against external drives.

What makes the Yoga Pro 9i interesting is its two USB-C ports. One is labeled USB-C (20 Gbps) and the other is labeled Thunderbolt 4 (which means 40 Gbps) [see the ports diagram from this April 29 post]. Theoretically that means port 3 (USB-C 20 Gbps) tops out at half the speed of port 4 (USB-C Thunderbolt 4 40 Gbps).

And indeed my only Thunderbolt 4 NVMe enclosure — an Acasis TB-401u claims to support that 40 Gbps top rate. The on-the-ground reality is, however, something quite different with a Sabrent Rocket 1TB NVMe 1.3 SSD  installed therein. Much of this comes from an older v1.3 SSD inside a 1.4 enclosure with access to TB4/USB4 compatible ports. But these results fall far short of what I’d expected to see:

This looks like results for a typical USB 3.x UASP device IMO

In fact, I got at least some better results from a less-capable Crucial CTP2000P3SSD8 (2TB, NVMe 1.3) inside a less capable enclosure (Sabrent EC-NVME: USB 3.1 Gen2) in the slower USB-C 20 Gbps port. Here they are:

Big bulk reads (top left) are much faster, but everything else is (mostly) slower.

There’s a lot of interesting stuff going on here. What I take from it is that for the fastest backups and big file transfers (video, AI models, and the like) you’re better off spending more on a faster enclosure and a faster SSD to get the most out of the connection. I’m going to have to systematize this, and run some more tests. Great fun!

Pondering AI PCs Means TOPS

Leave a comment

Since last Friday (April 26) I’ve been working with the Lenovo Yoga Pro 9 laptop. It’s also called a Yoga Pro 9i. I’m a little mystified by the “i” that comes and goes for this device name. If you look at the lead-in graphic you can see the User Guide calls it “Pro 9i” while Lenovo Vantage calls it “Pro 9.” It’s an early AI PC from Lenovo, which means it has a Copilot key and a built-in AI processor, aka NPU (Neural Processing Unit). As I’m now learning, pondering AI PCs means TOPS (trillions of AI or “tera” operations per second) matter — a lot!

If Pondering AI PCs Means TOPS Matters, What’s the 9(i) Got?

According to Intel Ark the name of the NPU integrated into the Intel Ultra Core i9 185H CPU is “Intel AI boost.” Otherwise, there’s precious little info available about its capabilities except for the frameworks it support. For the record, those are Intel’s own Open VINO, WindowsML, DirectML and OMNX RT.

I had to turn to Copilot to get more information about the 185H NPU. Here’s what it told me:

Intel’s Core Ultra “Meteor Lake” offers an AI Boost NPU with 10 TOPS

Since I’ve learned to verify whatever Copilot tells me, I found this stat verified at Tom’s Hardware in an April 9 story. When I asked Copilot directly “What’s the TOPS rating for the AI Boost NPU in the Intel i9 185H?” it came back with a higher number that I couldn’t verify. Here’s what it said:

The Intel Core Ultra 9 185H processor features an AI Boost NPU that can perform approximately 34 trillion operations per second, which translates to 34 TOPS (Tera Operations Per Second)12.

The second source it cites may explain this apparent discrepancy, though: the 10 TOPS is what the NPU itself contributes. But Arc and NVIDIA GPUs can also support the same AI frameworks mentioned above, and can thus add to a unit’s overall TOPS rating.

Put this into more Copilot context that asks if it itself can use NPU resources:

Microsoft Copilot is now set to run locally on AI PCs with at least 40 TOPS (Tera Operations Per Second) of NPU (Neural Processing Unit) performance.

Given that the Yoga 9(i) comes close to that number, I’m still wondering if it qualifies or not. So far, I can’t find any details that lead me definitively to an unequivocal “Yes” or “No.” Sigh.

The Next Generation Gets It, For Sure?

Another Tom’s story, also dated April 9, says the next “Lunar Lake” generation will include an NPU rated at 45 TOPS. Further it also asserts that PCs with such chips will offer 100+ TOPS overall when they become available. AMD likewise says it will play in that same ballpark, as will the Snapdragon X Elite chips.

I’m still unsure as to whether or not my current review unit — that is, the Lenovo Yoga 9(i) has enough AI oomph to run Copilot workloads locally. I’ll keep banging away at this, though. Eventually, I’ll figure it out. At this point, I’m still at the start of the learning curve…

Rereading Tom’s Hardware I See This…

The Tom’s Copilot Locally story relies mostly on quotes from Intel to set things up — namely, from Todd Lewellen, VP of Intel Client Computing Group. He says:

“[..]And as we go to that next gen, it’s just going to enable us to run more things locally, just like they will run Copilot with more elements of Copilot running locally on the client. That may not mean that everything in Copilot is running local, but you’ll get a lot of key capabilities that will show up running on the NPU.”

This seems pretty clear that the current generation — including the Core Ultra i9 185H in the Lenovo Pro 9i  — does NOT fall under this umbrella. That said, I think it leaves open whether or not it will make any difference for other AI workloads. Should be interesting to get to the bottom of this!
