Lenovo Yoga 3 Pro Review: Refreshed With Faster Core Mby Brett Howse on March 13, 2015 8:00 AM EST
It would be fair to say that Lenovo was a pioneer in the convertible Ultrabook lineup with the original Yoga. Last year, they updated the Yoga lineup with the introduction of the Yoga 2 Pro. This new model came with a Haswell-U series CPU, along with a 3200x1800 resolution display, all in the Yoga form factor with a 360° hinge. The display was a highlight for the model year, with the Yoga 2 Pro having one of the highest pixels per inch of any laptop available last year. In October 2014, Lenovo took the wraps off of their latest incarnation of the flagship convertible Ultrabook with the launch of the Yoga 3 Pro.
The Yoga 3 Pro was not just a refresh of the internals of the Yoga 2 Pro, but an altogether new creation. The new model is 17% thinner than the outgoing model, and 15% lighter. Rather than power the Yoga 3 Pro with the traditional Ultrabook Intel Core U series processor, Lenovo decided to go for the Broadwell-Y based Core M processor for the Yoga 3 Pro. This has its pros and cons, as we will get to later in the review, but the Broadwell-Y processor has a couple of changes over the Broadwell-U which was launched later. The Thermal Design Power (TDP) of Core M is a mere 4.5 watts, down from the 15 watt TDP of the U series processors which powered last year’s Yoga 2 Pro, and perhaps more importantly, the physical size of the chip, and the Z-height, are both smaller, enabling thinner and lighter devices.
When Lenovo first launched the Yoga 3 Pro, it was offered with the Core M-5Y70 processor. Lenovo has provided us with their refreshed model, which dumps the original Core M for the Core M-5Y71 which was recently released by Intel. This new processor bumps up the performance, and gains an additional 100 MHz base clock, and 300 MHz boost, with the 5Y71 now boosting to 2.9 GHz. It is a decent increase, and it is done in the same 4.5 watt window.
So Lenovo has taken a bit of a departure here with the Yoga 3 Pro. The rest of the Yoga lineup consists of Broadwell-U processors, and will therefore be more powerful. But not everyone needs or uses all of the power that they have, so in the quest to design a thinner and lighter device which is going to be more portable, the Core M is really the only solution for today’s computing landscape. What we need to know is what kind of performance you can expect in a premium Ultrabook such as this.
Below is a table of the specifications of the Yoga 3 Pro to summarize all of the components and compare it to last year's Yoga 2 Pro.

There are a couple of things worth mentioning from the specifications. Whereas last year’s model had several SKUs with different processor, memory, and SSD options, the Yoga 3 Pro has simplified the lineup, and provided likely the best combination for price and performance. The Yoga 3 Pro now comes with 8GB of DDR3 standard, and a 256GB SSD or 512GB SSD. The only other difference in the models now is the color, with Lenovo offering Light Silver, Clementine Orange, and Golden as the options.
For those looking for a convertible laptop, there are basically two camps. Devices which have the internals in the keyboard like a traditional laptop will be better balanced when using it as a laptop. The other device is a tablet with an attachable keyboard, such as the Surface 3 Pro. There are pros and cons to each approach, and each device can be better at one scenario than another. If you are after a device which can be used as a laptop more than a tablet, then Lenovo’s Yoga range certainly has a lot of appeal. It keeps the traditional form factor of a laptop, and through a well-designed hinge allows for a lot more versatility than a traditional clamshell notebook computer. It all starts with design.

name99 - Friday, March 13, 2015 - linkGood luck with that. Intel puts more care into the design of the glue those stickers use than practically anything else they ship.
After you do finally manage to pull the sticker off, you're left with a nasty glob of gunk on your machine, and it's not clear quite what will remove it while not hurting the finish of the machine. Acetone? Alcohol? Vinegar?
fokka - Friday, March 13, 2015 - linktry baby oil. i agree though, those pesky stickers should simply use the glue they use on post-its, that would be nice for a change. or, you know, get rid of those useless things all together.
jabber - Saturday, March 14, 2015 - linkActually I've found gently prising them off slowly lifts most of the glue with the sticker, especially when they are new. Then use the sticker to dab over any glue left gets 99% of it. Not difficult.
mkozakewich - Saturday, March 14, 2015 - linkOils destabilize rubbers. Try accidentally leaving a bit of turkey stock in the rubber part of a baster, or try eating peanuts while chewing gum.
Alexvrb - Sunday, March 15, 2015 - linkI would probably use Goo Gone, if I was prone to caring about removing factory stickers.
Manch - Sunday, March 15, 2015 - linkwd40. put a spot on a rag and wipe. then clean with alcohol.
limitedaccess - Friday, March 13, 2015 - linkCan verify that it is actually 4.5w TDP and not set for 3.5cTDP? The original was version was found to use the lower cTDP setting which is why performance was low (especially in gaming).
Was the performance actually sustainable? For instance the SP3 i3 did not show performance regression in gaming benchmarks until after the first pass of Dota 2.
I'm also wondering whether or not mobile reviews from now on should start looking into sustained performance and perhaps monitoring what clock rates actually are when in use.
What were the temperatures?
limitedaccess - Friday, March 13, 2015 - linkJust to add in general I'm wondering in mobile reviews are they actually being down to account for performance differences under extended use?
We now see the market move towards more variable and burst based performance I think this does need to be looked at more. A 10 minute gaming benchmark for instance may not represent an actual extended game play session if this isn't accounted for.
Brett Howse - Friday, March 13, 2015 - linkCPU Z shows it as a 4.5w part, and the clock speeds agree. I actually was hoping it would be cTDP up to 6w since it has a fan but it does not appear to be.
Sustained performance did not appear to be a big factor. I ran Cinebench R15 six times in a row (which took about an hour total) and all of the scores were within a fraction of a percentage of each other.
fokka - Friday, March 13, 2015 - linki think a cTDP of 6w would be a better fit for an actively cooled 13-inch machine, hell, i could even get behind a cTDP of 10 watts. the gap between 4.5 and 15w just seems so big otherwise. but with power states and turbo clocks diluting the whole TDP-game anyways, i don't even know what i want in a cpu anymore. o.O
