Microsoft Surface Pro 2 Reviewby Anand Lal Shimpi on October 21, 2013 12:01 AM EST
When Microsoft introduced its first Surface devices last year, it did so in a staggered fashion. Surface RT showed up first, then four months later Surface Pro went on sale. Despite sharing a lot of the same DNA, the response to Surface Pro was much better than what we saw with Surface RT. While Surface RT suffered a lot from being a new platform that lacked the support of decades of Windows applications, Surface Pro had no such issue.
Instead, Surface Pro offered the promise of a tablet that could potentially replace your notebook and desktop as well. Microsoft’s strategy with Surface Pro mimicked the market transition we saw years earlier. The notebooks that replaced desktops over the 2000s did so by being able to work as both notebooks or desktops. Similarly, Microsoft hoped that Surface Pro could act as both a tablet and a notebook for those users who didn’t want to carry two devices.
By and large, Microsoft was successful in achieving that vision. Although as with all devices that attempt to fulfill multiple roles, Surface Pro presented a set of tradeoffs. It wasn’t as portable and didn’t last as long on a single charge as a conventional ARM based tablet. It also didn’t have the same keyboard or in-lap experience as a PC notebook. You got a compromised experience on both sides of the fence. Just as with Surface 2, Microsoft is committed to a more aggressive update cadence to its Surface Pro hardware as well. Here we are, almost 9 months since availability of the original Surface Pro, reviewing its successor.
Unlike Surface 2, Surface Pro 2 shows almost no signs of change on the outside. It reminds me of the pre-iPhone/iPad era where expecting a dramatic chassis redesign a year after introduction was considered ludicrous. Surface Pro 2 keeps the exact same finish, dimensions and weight as the original Surface Pro.
It’s unfortunate given how much thinner and lighter the device could be this time around. I suspect Microsoft has a three year plan for Surface Pro. It could move to a thinner design this year and drop performance by going to a 6W Haswell SKU, keep performance the same but pay a thermal penalty with a 15W Haswell or wait until Broadwell next year to shrink the chassis (hopefully without much of an associated performance reduction). I can understand why Microsoft chose the latter, it’s still just frustrating as I would’ve loved a thinner/lighter Surface Pro.
I also lament Microsoft’s decision to update the VaporMg finish on Surface 2 but not on Surface Pro 2. I really like the new finish both in feel and in color. Surface 2’s resistance to picking up fingerprints is an added bonus on that front. Alas, it’s an update that I’m guessing the Surface Pro lineup won’t get until next year.
Surface Pro 2 also retains the same front and rear facing cameras as its predecessor, both 1.2MP units and it doesn’t get the new 3.5/5MP sensors from Surface 2.
You still get a bundled Wacom active digitizer with Surface Pro 2, just like with the original. I’m hardly a creative professional, but from what I’ve experienced with the pen it’s really a great addition for those folks who are. I’ll point you at none other than Gabe from Penny Arcade who did a great post on an artist’s perspective of using the Surface Pro’s stylus. Spoiler alert: he likes it a lot. If I illustrated for a living, I probably would too.
Surface Pro 2 inherits the same kickstand and branding decisions as Surface 2. As I mentioned in my Surface 2 review, the new 2-stage kickstand is awesome and a huge improvement over its predecessor. The kickstand now opens at 24 and 40-degree angles, the latter enables more comfortable use when you’re not typing at a desk. The new kickstand also ditches the Windows 8 logo in favor of the Surface logo across the back.
Finally, Surface Pro 2 does get the new 1080p panel from Surface 2 (albeit a brighter implementation). There’s no improvement in resolution compared to the original Surface Pro, but color accuracy is a lot better.
I did notice an odd display corruption issue on Surface Pro 2 when waking up from sleep (pictured above). Resetting the device or sometimes just doing another sleep/wake cycle was enough to fix it. Microsoft tells me it’s aware of the problem and plans to issue an update shortly to address it. We only got review samples a few days prior to the NDA lift, I get the impression that it was a lot of work to get final hardware out the door in time for this launch. Update: Microsoft traced the issue back to a later revision of an Intel graphics driver. After release, a Surface Pro 2 update rolled back to an earlier optimized driver that no longer exhibits the display corruption on wake issue.
Internally we see where Microsoft spent most of its time updating Surface Pro. It all starts with an upgrade to Haswell. Surface Pro 2 features Intel’s Core i5-4200U, a dual-core 1.6GHz 15W Haswell part with Hyper Threading, 3MB of shared L3 cache, and a max turbo frequency of 2.6GHz. Just like last time, I had no issues hitting 2.6GHz on Surface Pro 2. I would see 2.3GHz far more frequently however.
As Surface Pro 2 is rather thick by Ultrabook standards, you get the full performance of the 4200U. I ran a multithreaded Cinebench 11.5 test on Surface Pro 2, comparing it to Apple’s 13-inch 2013 MacBook Air under Windows 8. The two deliver identical performance, just in different form factors:
The 4200U is nearly identical to the base CPU you get in the new 2013 MacBook Airs, the only difference being that you get Intel’s HD 4400 graphics vs. HD 5000. Apple’s obsession with graphics performance explains the difference, although it’s disappointing to see Microsoft not sharing the same obsession. To Microsoft’s credit the difference between Intel’s HD 5000 and HD 4400, when constrained by a 15W TDP, just isn’t very large. The real benefit to going with HD 5000 over HD 4400 has to do with power consumption, since you can get similar performance at lower frequencies/voltages thanks to a doubling of the number of EUs in HD 5000.
It’s not just the CPU that’s changed this time around, Microsoft did extensive work under the hood of Surface Pro 2 to further reduce power consumption. Haswell ULT supports LPDDR3, a feature that Microsoft chose to take advantage of in pursuit of lowering power consumption. All other components on the motherboard are also optimized for power consumption. The result is a device that looks like and is cooled similarly to its predecessor, but is appreciably cooler/quieter in operation. While the original Surface Pro would spin its fans up on a regular basis, Surface Pro 2 is far more hesitant to do the same thing. In what I’d consider to be light to medium tablet use, Surface Pro 2 behaves like a passively cooled device. When the fans do ramp up, they aren’t any louder than before as far as I can tell.
Just like the original, Surface Pro 2 retains a full SSD rather than an eMMC solution. We’re still dealing with an mSATA based drive here, but Microsoft expanded the available capacity options. The combination of DRAM/SSD/price options are in the table below:
|Microsoft Surface Pro 2 Storage Configurations|
The most interesting options are unfortunately the more expensive models. I think the sweet spot is likely the 8GB/256GB version, which also happens to be how my review sample was configured. Unfortunately the LPDDR3 is soldered on board (as with all modern Ultrabooks) so that’s not user upgradeable. The SSD is technically serviceable, but there’s a ton of risk associated with doing so as you have to take apart your Surface Pro 2 to do so. Once again Microsoft refuses to equip Surface Pro with a Thunderbolt port, which would help greatly in dealing with high performance storage expansion concerns. There is still a USB 3.0 port at least.
Surface Pro 2 is compatible with all of the new dock accessories, including the new touch and type covers. I went through the improvements to both of those in our Surface 2 review already, but in short they are great. I still prefer the new type cover as I can type a lot faster on it, but the new touch cover is significantly better than its predecessor. Neither is included in the cost of a Surface Pro 2, so factor in another $119 - $129 depending on which cover you end up with. I noticed the same trackpad disappearing issues on Surface Pro 2 as I did on Surface 2, Microsoft claims a fix is in the works.

Surface Pro 2 ships with Windows 8.1 Pro x64. Since there's no connected standby 64-bit version of Windows 8/8.1 yet, Surface Pro 2 ships without the feature. It also continues to behave more notebook like in the sleep/wake sense as a result. There's a delay between when you press the power/lock button and when you'll see the tablet respond as the system comes out of its sleep state. Ironically Surface Pro 2 comes with nothing more than a link to try Office 2013, while Surface 2 comes with a free copy of the Home & Student edition.
Like Surface 2, Surface Pro 2 ships with 150% DPI scaling enabled for classic desktop applications. Unfortunately even under Windows 8.1 there are a lot of issues with DPI scaling in 3rd party applications and touch targets. Chrome for example is mostly unusable as a touch browser in classic mode.
There’s not much difference between the new 1080p panel in Surface 2 and what’s in Surface Pro 2. Both feature a laminated cover glass and the same increase in color gamut. The end result is a big improvement over the previous generation, but not quite up to the level of color accuracy we’ve come to expect from cheaper tablets.
Surface Pro 2's display does get substantially brighter than the panel in my Surface 2 review sample. One thing I don't have a good feel for is just how much variation there is between panel suppliers into the Surface lines.
It really is a very good display, it just could be better.
While multitasking on Surface 2 can struggle, the same really can’t be said for Surface Pro 2. The tablet is effectively a Haswell Ultrabook, capable of delivering the exact same performance as a 2013 MacBook Air – but in the form factor of a thick tablet. The performance of Intel’s Core i5-4200U is a fairly known quantity at this point, but to put Surface Pro 2’s tablet performance in perspective here are some comparisons to the best of the best in the ARM tablet space.
I ran tests using both Chrome and IE11, the latter is really only optimized for SunSpider and horribly unoptimized for everything else. In general you're multiple times better performance than what you can get from a quad-core Cortex A15 based device. If we look at Kraken, Surface Pro 2 running IE11 completes the test in 1/4 the time as Surface 2 running the same browser.
Intel’s HD 4400 is good enough for light gaming and is a huge step above what you can find in a traditional ARM based tablet. Microsoft only gave us a few days to review both devices so I didn’t have a ton of time to re-characterize the performance of Intel’s HD 4400, but I’ve done that elsewhere already.
My review sample appears to have a SK Hynix based SSD. I ran it through the same modified IO tests I did on the ASUS T100:
Our Android IO tests rely on Androbench with a relatively limited LBA span. I increased the difficulty of the test a bit under Windows 8.1 but still kept it reasonable since we are dealing with eMMC solutions. I’m testing across a 1GB LBA span and testing for a period of 1 minute, which is an ok balance between difficulty of workload and sensitivity to the fact that we’re evaluating low-class SSDs here.
Surface Pro 2 is a completely different league of IO performance. The number to pay attention here is the tremendous increase in random write performance compared to the eMMC solutions we’ve tested. I suspect the gap increases if we were to look at worst case sustained random write performance. Killer sequential performance definitely helps Surface Pro 2 feel quick.
Surface Pro 2 retains the same 42Wh battery and 48W charger as the original Surface Pro. I wasn’t pleased at all with the battery life of the original design, and I had hoped for a significant increase in battery life with Surface Pro 2. Microsoft claims up to a 75% increase in battery life compared to the original. In our 2013 tablet battery life test that turned out to be a 40% advantage – not shabby, but not where it needs to be. Update: Microsoft issued a firmware update that brings Surface Pro 2 up to 8.33 hours of battery life in our web browsing battery life test, or 76% better than the original Surface Pro.
I’m also beginning to think that Haswell’s video decode engine may not be all that power efficient. We did see better results out of OS X, but it’s still nowhere near what’s possible on the best ARM platforms.
Surface Pro 2 is a good improvement over its predecessor. The platform is quicker, quieter and boasts longer battery life as well. The new kickstand is awesome, as are the new touch/type covers, and the new display is a big step in the right direction. If you were tempted by the original Surface Pro, its successor is a solid evolution and that much more tempting.
I really like using Surface Pro 2 and Windows 8.1 in general as a productivity focused tablet OS. The screenshot below really helps illustrate what I would love to do on most tablets, but what I can only do (well) on a Surface:
Writing an article on the left, touch enabled web browsing on the right. Switching between both applications is seamless, and I’m just as fast (if not faster) from a productivity standpoint on Surface Pro 2 than on a traditional notebook/desktop – at least for this usage model. There’s really something very compelling about having the best of both worlds in one system. I literally can’t do this well on any other tablet, and ultimately that’s what Microsoft was trying to achieve with Surface. You can do it with Surface 2, you can just do it a lot better with Surface Pro 2.
When Surface Pro first launched, it wasn’t just a good device, it was arguably the best Ultrabook on the market. Surface Pro 2 launches into a much more competitive marketplace. I don’t know if I can make the same statement about it vs. Ultrabooks today. That’s not a bad thing as it is still a very different type of device, but it does make for a more difficult buying decision.
Surface Pro 2 isn’t the perfect notebook and it isn’t the perfect tablet. It’s a compromise in between. Each generation, that compromise becomes smaller.
What I was hoping for this round was an even thinner/lighter chassis, but it looks like we’ll have to wait another year for that. Battery life is still not up to snuff with traditional ARM based tablets, and Surface Pro 2 seems to pay more of a penalty there than other Haswell ULT based designs – I’m not entirely sure why. Parts of the rest of the world have moved on to things like 802.11ac and PCIe based SSDs. Microsoft appears to be on a slightly strange update cadence with its Surface lineup, and for the brand’s sake I hope we see that rectified next round. It’s not enough to just put out a good product, you have to take advantage of all technologies available, when they are available. Just like last year, my recommendation comes with a caution – Surface Pro 2 is good, I’m happier using it than I was with last year’s model, but the Broadwell version will be even better. What’s likely coming down the pipe are improvements in the chassis and in battery life. You’ll have to wait around a year for those things, if you can’t, then this year’s model is still pretty good.
