General Performance
With an Intel Core i5 4200U, 4GB of DDR3L-1600, and a 256GB Samsung SSD inside, we are right in the middle of the road as far as the Yoga 2 configurations available. It is standard fare for an Ultrabook, though the 4GB models are thankfully being phased out by most OEMs now. Being that this device can pull double duty as a laptop or a tablet, we will also do some comparisons on the tablet side.
Performance Graphs
We’ll start with general performance. PCMark gives us an evaluation of several scenarios, as well as storage performance. Being designed as a laptop, the Yoga 2 Pro does not suffer as harshly from throttling as something like the Surface Pro 3 does, although the SP3 does have the slightly faster i5-4300U.
Performance is right where we’d expect it to be for the 4200U. There were no signs of throttling during normal operation.
For storage, the Yoga 2 Pro comes equipped with a Samsung OEM SSD. This is likely the same drive used in other devices such as the Surface Pro 3, and the performance is similar. We'll likely need to wait for the next generation Yoga before we see M.2 PCIe SSDs improve storage performance.
Gaming Performance
While the Yoga 2 Pro is certainly not considered a gaming machine, a user may want to play the odd game on it. With Intel HD 4400 graphics though, it would be practically impossible to game at the native resolution of this panel.
With the Intel HD 4400, the Yoga 2 Pro does fine in low demand benchmarks such as Ice Storm, but it is quickly taxed to the point of being unusable on titles with more graphically intensive workloads. Tomb Raider and Bioshock, even at the value settings, are almost unplayable on the Yoga 2 Pro. You'll want to either drop to minimum detail settings or stick to older/less demanding titles (and thankfully there are plenty of those available).

Only sub-pixel density matters to your eyes.Rdmkr - Friday, August 1, 2014 - link
"Only sub-pixel density matters to your eyes." - I disagree. Luminance detail is what matters most to the eyes and this is determined by the pixel density, not subpixel density. See http://en.wikipedia.org/wiki/Chrominance#mediaview... ; first is luminance, second chrominance.kyuu - Thursday, July 31, 2014 - link
I wish they made the 11.6" model with a 1080p IPS screen. Everything is great about it except for that damn screen. And the HDD, but I'm hoping that's replaceable (or can at least accept an M.2 like the 13" models can).And I'd prefer some AMD silicon in there, but that's just wishful thinking.

Thanks for a great review - although others have commented on it being late, I find it interesting to get a full review with the added benefit of commentary from actual long-time usage of the device.However, I'm missing some thoughts on using this as more of a work machine rather than a consumption device, especially for more demanding tasks such as video editing. Do you have any additional thoughts here?
What kind of performance delta could one expect between this and the i7 version? In many reviews the difference in performance even between ULV Haswell i5/i7 systems and more powerful chips like the 28W versions in the MBPr 13" seems negligible (3-400 points in PCMark 7). However I'm left wondering if these tests don't tax the systems over a long enough time, so that any differences due to throttling (or inability to sustain turbo speeds) might be hiddden. Could this be the case? I'd imagine near identical performance from these systems due to both being 2C/4T with similar Turbo speeds, but the nearly 1GHz difference in stock speeds should lead to a significant difference under sustained loads, no?
The reason I'm interested in these use cases is that my fiancee needs a new laptop. She's studying filmmaking, so she wants something that would be able to run Avid Media Composer, but still is thin and light enough to carry to school every day. The calibration issues with the display don't matter as we have a professional level external monitor at home, and any really heavy work would be done on a desktop. I know the system requirements for Media Composer state that a quad core processor is required, but this would exclude the MBPr 13" as well, so I'm taking this with a grain of salt. My question is in essence this: is there any reason why the Yoga 2 Pro (i7) would not be a good fit for this kind of usage?

Hi Valantar. While I haven't specifically tested the software you listed so I can't comment on how well it would run, in the benchmarks I specifically made sure to include other similar sized machines. The one closest to what you are asking about is the Acer Aspire V7-482PG-9884 (by the way I love that model name). It's got the 15 watt Haswell i7-4500U so it should be a close comparison as far as CPU performance. The GPU side is different of course because it has a GeForce GT 750M, but on the CPU benchmarks it should be fairly accurate.The performance difference isn't huge, because they are both dual core, four thread CPUs with the i5 having a base clock of 1.6 GHz and ramping to 2.6 GHz, with the i7 base at 1.8 GHz ramping to 3.0 GHz. The i7 certainly has an advantage but it's not a lot, so if you are talking about a 15 watt part, the performance is similar, but clearly lower for the i5.

Thanks for the clarification! I'm still interested in how this would compare to 28W Haswell, but I can see that AnandTech hasn't reviewed a MBPr since 2012, so I guess I'll have to look around a bit for the answer to that.As an owner of the device, how would you rate it when it comes to heavier tasks? Does it feel quick when, for example, editing a video or photos? Or would you say it's mostly suited for lighter/more consumption-oriented tasks?

Quadrupling resolution is stupid. I wish the PC market would stop doing this.There is an optimal resolution for a screen size. Too low resolution and things do not look sharp. Too high resolution and there is needless extra cost, gpu draw and power, and incompatibility with normal resolutions for multi-monitor setups (even using an standard external screen some of the time becomes impossible).
For a 13" screen, 768p is terrible, 900p good, 1080p excellent, beyond 1080p too high.
If Windows ever becomes fully resolution-independent, then ultra-high-res becomes OK, but that requires architecture changes for working with more than one screen resolution simultaneously.

Nice review on the Y2P. I came across many similar reviews discussing the high dpi, wireless card, and yellow display as being weaknesses. So I cross-shopped the Acer S7 (disliked the key configuration on a previous acer), Yoga 2 13", XPS 12 and 15, Macbook Air and ended up scoring a Yoga 2 13" in a sweet configuration from BB: i5-4210U, 8 GB of RAM, Intel 7260 AC wireless, and a 128 GB Samsung XP941 M.2 SSD (which I had no idea about until I brought the machine home). For those that don't know, the Yoga2 (non-pro) comes with the standard 1080p screen (I decided against the Y2P screen). The tradeoff with the Yoga2 is 0.5 lb. Oh, and BB had it on an .edu discount, so $899-125-10% USPS moving discount = $675 and tax.Initial thoughts: blazing fast machine for everyday tasks. Great 7-9ish hour battery life on power saver mode. PC Mark 7 basic score was 4953. Boots in 5 seconds, and wakes from hibernation in 8-10 seconds. No wifi issues so far (still in a 802.11g household). The touchpad seems to have a coating on it as everything wipes off nicely and feels soft-touch like the rest of the palm rest area.
Expansion-wise: I popped a 64 GB Transcend Jetdrive into the SDXC slot. On the Lenovo forums, people have identified an extra, internal M.2 connector, so when those drives become mainstream, there's room for more.
Most of the reviews for the Yoga 2 13 are based on a 4 GB of ram and a non-SSD. I'm glad Lenovo came out with this configuration cause for most users, I think it's the best of all worlds.

I got the exact same laptop and exact same deal along with Best Buy 10% rewards. The XP941 SSD was certainly a surprise. My only disappointments was the pentile screen and the inability to increase the TDP in Intel extreme tuning utility.FwFred - Thursday, July 31, 2014 - link
I can confirm I've been using the 7260 AC with no issue since last November. The replacement is fairly cheap, but it was hard to find someone selling the proper version. The swap was pretty easy except for re-attaching the antenna leads. If my fingers were about 10% of their actual size, I think it would be about right :-/
