The Lenovo ThinkPad X1 Yoga Review: OLED and LCD Tested
by Brett Howse & Brandon Chester on September 29, 2016 11:30 AM ESTGPU Performance
Once again, since this is likely the last Skylake Ultrabook to be tested here, it’s also likely our last look at Intel’s HD 520 GPU. It’s been a nice improvement over Broadwell, even though the elusive Iris version has not made it’s way here. With 24 EUs in the GT2 GPU, it ends up being reasonable for low end games, and Intel seems to be promoting integrated GPU performance with more effort recently.
The X1 Yoga was run through the standard GPU suite, with a few synthetic tests, as well as Dota 2 for a low end game that can be played on an iGPU.
3DMark
Once again, there are no surprises with the HD 520, and the X1 Yoga falls in-line with the other Skylake GT2 units.
GFXBench
Much like 3DMark, the X1 Yoga scores similarly to the other Skylake devices tested.
Dota 2 Reborn
Valve recreated Dota 2 with a new gaming engine, which limits our selection of devices to compare against since the new Reborn version was launched. As an online game, it is also constantly updated.
The X1 Yoga outscored the Razer Blade Stealth in the lightest test, but was unable to pass it in the higher quality tests. Due to the nature of it being an online game, with frequent updates, this could be due to game engine changes as well as driver differences between the tests (typically notebooks are only short-term review units, so it can be difficult to maintain consistency). The margins are not huge though, and although the game is somewhat playable on our medium test, it really can only be played well at the lightest settings.

The 520 is fine for anything outside of gaming. And light gaming like CS:GO is perfectly ok to. You don't have to play at native resolution.BrokenCrayons - Thursday, September 29, 2016 - link
Playing around with video games wasn't the focal point of that comment. I'd hardly consider it relevant in the modern world when gaming is a better chore for purpose-built hardware (consoles) or mobile scenarios where a person is compelled to wait for something for a few minutes (tablets/phones).That's why I said, "1080p is a stretch for the 520 doing anything intensive." That statement covers a wide range of other tasks that stress a graphics processor but have nothing to do with "playing" and everything to do with working.

Majority of users just do internet, office, and media work, with primary stress on the CPU. I wouldn't expect anything more from an ultrabook.BrokenCrayons - Friday, September 30, 2016 - link
Your personal expectations may not align with the expectations of other people. It's a computer and therefore will be subjected to a variety of different workloads. Just because it meets Intel's specs for battery life and thickness doesn't grant it immunity from user demands."Sorry end user, I'm an ultrabook so you simply can't perform tasks x, y, and z at all." -- Sounds a bit silly doesn't it? It sounds even more silly when a certain category of computing tasks was performed on say a old 386DX running at 25MHz packing 4MB of 30-pin RAM in 8 512KB sticks. But oh no, a Thinkpad X1 can't perform the modern version of that chore. Why? Because ultrabook!

you're going off the railsMrSpadge - Thursday, September 29, 2016 - link
What could you possibly want to work with such a device where the GPU and screen resolution matter?Video re/encode: it's the video resolution, not the screen
CAD, 3DS etc.: good luck with Intel OpenGL drivers to make it run at all. And if it does, a factor of 2 or 3 more performance from the Iris / Iris Pro won't change the experience much.
GPU computing: Intel not supported, driver bugs etc.
Some corner case benchmark: well, maybe it helps here

"What could you possibly want to work with such a device where the GPU and screen resolution matter?"Quite a few computer users spend quite a bit of time fretting over GPUs and screen resolution. Evidence can be found by reading computer reviews, monitor reviews, GPU reviews, advertisements for computers, technical forums, or just by asking around. In modern times, we even spend significant time discussing the graphics processors and screen resolutions of our telephones. I can't think of many situations where those two metrics aren't relevant concerns.

Just because it's listed in specs and some people get crazy about it doesn't mean it really matters. when was the last time you badly wanted to run a game on your phone but your GPU was too slow?Samus - Friday, September 30, 2016 - link
it's important to note most modern Thinkpad's do NOT meet many MIL-STD-810G specifications, presumably including this Yoga since the previous Thinkpad Yoga's didn't meet any of them. The most durable model, the T series, meets only 8 of the specifications and most of them mildly in comparison to the competition. For example, the Thinkpad T460 is guaranteed to pass the mechanical shock test (no details given on what the testing parameters are) precisely 18 times, giving the perception they are cherry picking a number.By comparison, the weakest modern Elitebook, the 8460\8470 (predates the 94xx/8xx/10xx series) bested the test 40 times at a distance of 3 feet and a repetition frequency of 30 seconds. It also did it while POWERED ON, and did not turn off. All these details are missing from the Lenovo data.
Additionally, certain tests, such as dust tests, are also cherry picked results by Lenovo, using a 6 hour cycle. By comparison, they use the MIL-STD guideline of a 24 hour continuous test, not four 6-hour tests.
Lastly, a number of tests are missing. Important ones, such as the impact pressure test (1500G) aka the "crush" test which is comically reproduced on YouTube by running over Elitebooks with a VEHICLE of some sort. But this could conveniently fall into Lenovo's category of high-vibration "multiple tests" again with no details or data provided.
Modern Lenovo Thinkpads are more in-line with HP Probooks and Dell XPS's. If you want most of the 810G compliancy the only economical devices are Elitebook 8xx/10xx series, various Dell Latitude 64xx\65xx series and the Precision 7000 series. It's important to note that Thinkpad's from over a decade ago were substantially more durable than the modern equivalent. At the same time, the competition, specifically HP, Dell and Panasonic, have all improved their durability every subsequent generation (although HP has been sacrificing durability for aesthetics in some recent models such as the 1020/1040.)
Comically, Lenovo sells various "shells" or cases for their Thinkpads to improve durability. My favorite one is the "healthcare" case. Look it up for a good laugh.
Also worth pointing out because a lot of people say the competition doesn't offer a "Yoga" competitor is yes, they do. The "convertible" form factor has existed for nearly 20 years. Windows 98 PC's came in convertible "tablet" options. The Elitebook 810G (11.6") is probably the most modern version of a convertible, offering all the flexibility of a Yoga with more durability and a lower price.

IMO, you should avoid language like the Fn and Ctrl keys are swapped from "default" arrangements as there is no default. Thinkpads have had Fn on the left corner for forever, and so do macs.Also the placement of Print Screen where there should be the Menu key remains inexplicable.
