The Lenovo ThinkPad X1 Yoga Review: OLED and LCD Tested
by Brett Howse & Brandon Chester on September 29, 2016 11:30 AM ESTPerformance
The X1 Yoga we have for review is likely going to be the last of the Skylake-U models to come across my desk. With the recent launch of Kaby Lake, many machines are going to be available with the updated CPU soon. But that doesn’t discount Skylake, which still offers some nice performance gains especially with Speed Shift coming with Windows 10, and a big update to the integrated graphics.
The review model came with the Core i7-6500U processor, while Lenovo also offers the Core i5-6200U, i5-6300U, and i7-6600U models. 8 GB of RAM is standard, and 16 GB is available as well, but on the Lenovo page, 16 GB appears to be only available with the most expensive CPU, which is unfortunate.
The X1 Yoga was run through the standard notebook lineup for tests, and will be compared against other Ultrabooks and 2-in-1s. The X1 Carbon from last year is a nice comparison because it’s the Broadwell version with the i7-5600U, so you will be able to see the progress with Skylake.
PCMark
Futuremark’s PCMark tests attempt to replicate real-world workloads, with lots of burst work and some sustained work with gaming and such. The Skylake X1 Yoga shows a nice performance gain over Broadwell here.
Cinebench
Unlike PCMark, Cinebench is a pure CPU task, with 100% CPU load for the duration of the test. There are both single-thread and multi-thread options as well. Here Skylake’s improved features like Speed Shift have less of an impact, and the overall performance is similar to Broadwell in the X1 Carbon, but remember the X1 Carbon is the i7-5600U as well, offering a tiny bit more MHz than the i7-6500U in the X1 Yoga.
x264
Like Cinebench, this test is a CPU bound test, where higher frequencies and more cores make a big difference. Unlike Cinebench though, Skylake does a bit better here and pulls a nice gap over Broadwell.
Web Tests
Although web benchmarks are an imperfect test, in the end we spend a lot of our digital time using the web, so it’s still important. With the launch of Windows 10, we switched from Chrome to Edge for our browser tests, and the different browsers will be pointed out in the graphs.
Once again, performance is pretty much in-line with other Ultrabooks, and the i7-6500U has the benefits of Speed Shift which can help out quite a bit on the bursty workloads of Javascript. It’s not a huge gain over the last generation, but it’s still an improvement.
Storage Performance
Storage is now a key selling point on laptops again. Most manufacturers are proud to say they offer PCIe storage, even if they tend to ship the cheaper TLC based drives. In the case of the X1 Yoga, we have both an LCD model and the OLED one to test, and they didn’t come with the same SSDs. The LCD model was outfitted with the Samsung PM871 which is a SATA TLC drive, and in this case 512 GB. The OLED one was a Samsung PM951, which is a NVMe TLC drive. On a premium device, it would be nice to see NVMe across the board, and preferably MLC storage, but margins tend to trump this and Samsung's TLC drives are a step above the rest. Lenovo also offers some drives with OPAL 2.0 certification, and NVMe drives up to 1 TB.

The PM871 shows its SATA roots, capping out at less than 600 MB/s. The PM951 is pretty much the standard NVMe drive for the last year, and its read performance shows the big benefit of getting off SATA, although the write speeds are somewhat lower due to the TLC flash.

If it wasn't explicitly mentioned to be one, then chances are no, it's not. It's probably your run of the mill low-end webcam, with poor quality, and an integrated mic that's both too quiet and peaks too easily at the same time.Brett Howse - Thursday, September 29, 2016 - link
No it has a fingerprint reader instead for Windows Hello.grant3 - Thursday, September 29, 2016 - link
Not type-C port, "... but the X1 Yoga does have MicroSD support for additional storage"Huh?? How does MicroSD make up for the lack of type-C ports?
Do the reviewers have the delusion that people only want type-C to plug in portable storage?
Unsure if they're clueless, or shilling for lenovo....

It doesn't make up for anything. Just pointing out what ports are there. You're reading a bit much into it.grant3 - Friday, September 30, 2016 - link
The conjunction "but" implies the second statement (partially) excuses the first. My perception is that reviewers have learned to soften their criticisms of preferred vendors.SeannyB - Thursday, September 29, 2016 - link
Thanks for the exhaustive display review. The lack of individual calibration is a big missed opportunity by Lenovo considering the development they did on the software side.I also have to wonder what the native gamut of the panel looks like. In a perfect world where Windows is fully color-managed, one would be more concerned about the panel's native gamut covering the common targets (AdobeRGB, DCI-P3, etc.) than whether it has explicit modes for them. Unfortunately the years tick by and Windows still lacks OS-wide color management. Maybe the advent of OLED consumer monitors and the "HDR" push will finally force the issue.

The native primaries/gamut volume are important, and for HDR standards (which are aiming at a future with Rec2020 primaries that far exceed what we can achieve on consumer panels right now) it seems like more must be better... but for someone actually using a display, even with HDR, saturation accuracy should tell you everything for all practical purposes--that is, we are well beyond the problems of LCD panels that missed some SRGB gamut, so the real question is not "do I see all the green in fully-saturated SRGB images?" but "how accurate are the fully-saturated colors I see?""99.8% of DCI-P3" looks impressive on a chart next to displays that don't have as much coverage, but if you want to use the display for real imaging, the important question is "how accurate is the display (at DCI-P3 or whatever your target is) before/after calibration?" 100% DCI-P3 is basically a worthless number (without accuracy numbers) unless the only colors you render are exactly DCI-P3 100% R/G/B.

Would really, really like some details on brightness levels, too. Assuming they/intel used a 10-bit display interface, HDR should be easily supported once application software catches up--but if the peak brightness is less than 500nits the payoff is diminished.Brandon Chester - Thursday, September 29, 2016 - link
It's standard 8bit per channel. Assuming 10bit color on an Intel laptop is generally going to be a losing bet :)Arbie - Thursday, September 29, 2016 - link
Please state in your reviews whether the micro/SD sticks out the side of the laptop, because it's pretty much useless if so. Thanks.
