It's the thinnest convertible laptop to date with a beautiful screen, and packs Intel's new Core M chip too.
I went into my Yoga 3 Pro testing with high expectations. After all, in our review of the Yoga 2 Pro
roughly a year ago, we described that machine as damn near close to the
“perfect laptop/tablet combo.” And now with this update, Lenovo sticks
with what worked well last time, and even makes the Yoga 3 Pro thinner
and lighter than its predecessor.
Then there’s the new hinging mechanism, which you just have to see in person to appreciate. You won’t find anything like this on another PC.
Gordon Mah Ung One gorgeous display
First, the really good news: The 13.3-inch, 3800x1200 IPS touch panel
looks amazing. In this day and age of 4K laptop displays, that
resolution may not sound like a lot, but the size of the screen puts
this Yoga’s 299 pixels per inch near the top of the pixel density heap
for thin-and-light computers. For comparison, the current 13-inch
MacBook Air display has 127 ppi, while the Surface Pro 3 hits 216 ppi
with its 12-inch screen.
There are still scaling issues in Windows 8.1 on high-res displays,
but dropping a 36.3-megapixel image onto the Yoga 3’s desktop will make
you remember why high-res panels are so damned beautiful. You’ll poke
your face to within inches of the Yoga 3’s screen to check out where the
detail stops. On our test image, a publicly available press shot from
Nikon, the detail didn’t stop.

And the display isn’t even what’s new in the Yoga 3 Pro—the
Yoga 2 Pro essentially had the same screen. The real conversation piece
is the watchband-inspired hinge that connects the display to the
computer. It looks like someone broke into a jewelry store, absconded
with a dozen Speidel watchbands, and machined them together for the new
Yoga’s hinge. But unlike a watchband that’s made to bend to and fro
without resistance, the hinge on the Yoga 3 Pro holds its place in
familiar Yoga fashion.
The new design is based on six hinges instead of the previous two.
This adds rigidity, and it lets the unit fold completely flat against a
surface. I’m not sure why you’d really want the entire unit flush
against a tabletop, but I suppose when you’re doing Yoga and your drill
sergeant is screaming at you to do the downward dog properly, you'd
better do it.
Gordon Mah Ung Thinner and lighter
Lenovo says the Yoga 3 Pro is 17 percent thinner and 15 percent
lighter than its predecessor. It’s officially 2.62 lbs, 13 inches wide, 9
inches deep and 0.5-inch thick. It’s so thin, in fact, Lenovo claims
it’s the thinnest convertible notebook in ze vorld!
That’s technically true, I suppose, but I’ll point out before the
peanut gallery does that the Surface 3 Pro is 0.36-inch thick. However...
the problem with that Microsoft spec is it doesn’t include the Type
Cover keyboard. And, I’m sorry, without the keyboard, the Surface Pro 3
is essentially useless for most real work. So the Surface Pro 3’s
effective width (keyboard cover and all) is 0.55-inch, and thus the Yoga
3 Pro is ze vinner!
Lenovo has made a few other nip-tucks to the Yoga 3 Pro. There’s now
one more USB 3.0 port than the Yoga 2 Pro, plus a handy combo USB 2.0
and charging jack. Lenovo also moved the power button back, responding
to complaints from people who hit the old button by mistake, putting the
machine to sleep.
In my experience, though, the new power button placement isn’t
enough—the button protrudes slightly and is still too easy to hit. At
this point, it might be wiser to recess the button more, or move to a
slide switch. I also had issues with the Windows button integrated into
the display: It requires so much pressure, the laptop slides back half
an inch when I try to activate it. I suspect it’s a problem with my
review unit, as others haven’t reported similar issues.
In our review of the Yoga 2 Pro, we dinged the unit for having a
shallow keyboard with insufficient key travel. The problem persists in
the Yoga 3 Pro. The machine’s thin profile certainly presents challenges
for keyboard design, but nonetheless, typing on the backlit keyboard
takes some getting used to. It’s always a bit jarring when the keys
bottom out too soon. The trackpad, fortunately, offers the same
silky-smooth experience that Lenovo delivered in the Yoga 2 Pro.
Other specs? For those keeping score, the review unit I received
featured a 256GB Lite-On M.2 SSD, 8GB of low-power DDR3 RAM, a 720p web
cam, 802.11ac and Bluetooth 4.0 radios, and Windows 8.1.
Gordon Mah Ung Enter Intel Core M
Besides the watchband hinge, the real big news is the CPU: Intel’s new Core M 5Y70, aka Broadwell.
This 5th-generation chip’s main claim to fame is lower power
consumption. In fact, Intel says the Core M 5Y70 in the Yoga 3 Pro is
rated at 4.5 watts versus the 15 watts of the Haswell-based Core i5
chips in the Surface Pro 3 and the previous Yoga. The Core M 5Y70 in the
Yoga 3 Pro features an upgraded graphics core (Intel’s HD 5300) and a
base clock of 1.1GHz, with the ability to crank up speeds to 2.6GHz when
needed.
Most convertible machines are about productivity and browsing, so a lot of people dismiss performance. But they do so at their own risk.
If performance didn’t matter, the world would still be happily driving
the same Netbooks with the original sucktastic Atom CPUs. So to measure
the performance of the Yoga 3 Pro, I tapped PCMark 8 and 3DMark. PCMark 8
runs simulated browsing, photo editing, video chat and light gaming to
measure performance. 3DMark, meanwhile, is a gaming and graphics
benchmark. You can see how the Yoga 3 Pro fared in this test in the
chart below.
Uninspired performance, but it may not matter
Compared to a Surface Pro 2 with a Core i5-4200U and a Surface Pro 3
with a Core i5-4300U, the Yoga 3 Pro isn’t very inspiring. As you can
see in the chart above, the oldest of the three convertibles
won our graphics battle. Why? The reason is mostly due to physics. The
Surface Pro 2 is about as thick as half a stack of pancakes and you
could probably beat a zombie to death with it. Its entire design is
built to endure high temperatures under heavy loads. But with the
Surface Pro 3, Microsoft opted for a thinner machine, and a more refined
experience. Under heavy workloads, the Surface Pro 3 throttles down to
control excessive heat.
Once we get to the Yoga 3 Pro we’re looking at an even thinner
notebook. In fact, if Lenovo is to be believed, it’s the thinnest
convertible ever made. To help accommodate this thinness—and not burn
your lap—Lenovo also throttles down CPU clock speeds to help keep heat
under control.
As you can see in the chart above, the fifth-generation Core M in the
new Yoga is slower than the fourth-gen Core i5 parts in PCMark 8’s Home
Conventional test, which uses a mix of web browsing, casual gaming,
word processing and video conferencing to measure performance. If you
plan on using the Yoga 3 Pro for hardcore Photoshop or video editing
work, think twice before pulling the trigger. But you probably won’t
notice any performance deficits during normal productivity use.
Afterall, this isn’t a Netbook that has problems typing the letter A.
Cool like Fonzie
Unlike the Surface Pro 3, which get warm under loads, the Yoga 3 Pro
runs surprisingly cool. There’s a small 1x4-inch strip on the bottom and
rear of the Yoga 3 Pro that gets warm during heavy use, but other than
that, it’s cool to the touch.
Interestingly, Intel touted the Core M as enabling fanless designs,
but Lenovo chose to embed a small fan. You can hear it on occasion, but
it’s very quiet. The fans in the Haswell-based Surface Pro 3 definitely
make themselves known, so score a win for the Yoga 3 Pro on acoustics.

Besides low temperatures, another benefit of performance-reducing CPU
throttling is increased battery life. It’s always odd for a
next-generation CPU to give up performance, but at least the Yogo 3 Pro delivers in the longevity department.
Using PCMark 8’s battery run-down test, the Yoga 3 Pro easily beat
the Surface Pro 2 and Surface Pro 3, as you can see in the chart below.
In PCMark 8, the Surface Pro 3 gave me about 141 minutes of run time
with 18 percent of battery life remaining, for a final battery score of
9,863. The Surface Pro 2 was next up with 175 minutes of run time; 12
percent of battery life remaining; and a score of 11,350. The Yoga 3
Pro’s final score was 15,224 after running the test for 208 minutes with
19 percent of battery life remaining. Basically, the Yoga 3 Pro and
Core M somewhat vindicate themselves against the older Haswell-equipped
Core i5 chips.
The bottom line
In the end, the Yoga 3 Pro is a worthy upgrade to the the Yoga 2 Pro and amazingly thin. But is it a Surface Pro 3 killer?
Gordon Mah Ung
Although it’s a tad heavier, it has better battery life and a larger
and even more pixel-dense display. While I’m a big fan of the pen
support in Surface Pro 3, I’ve never been happy with using it on my lap.
The Yoga 3 Pro, on the other hand, with its more traditional laptop
mode, works far better. So, yeah, maybe it is the Surface Pro 3 killer.
Now we just have to wait for the Surface Pro 4.
