The Surface 3 Reviewby Brett Howse on May 4, 2015 9:00 AM EST
Since the Surface 3 is a tablet that can replace your laptop, comparisons will be made between both devices. Because the new tablet is running full Windows 8.1 x64, it is possible to run the full benchmark suite that we have for laptops. On the tablet side, there are not a lot of cross-platform benchmarks so the only thing that can really be used is browser based tests. It is not ideal, but we have to work with what we have.
To summarize the Surface 3, it is powered by the top model of the latest Intel Atom 14nm stack. The Atom x7-Z8700 is a quad-core processor with a base frequency of 1.6 GHz. The CPU can turbo up to a maximum of 2.4 GHz, and all of this is done within a 2 watt Scenario Design Power. The review unit that I received is the $499 unit, so it only has 2 GB of LPDDR3 memory rather than the 4 GB offered on the higher priced model.
For comparisons against tablets, I have selected a sampling of several devices that have already been reviewed. Some of the devices are running on ARM processors, and several of the Windows ones run on Intel Core M, with a few more running on previous Atom architectures. To compare this device against any other device we have tested, please check out our Mobile Bench.
By attaching the keyboard, the Surface 3 becomes a pretty reasonable laptop, so to see how much of a performance drop off there is with tablet class parts, the Surface 3 was run through our Laptop suite as well. The Atom is also equipped with eMMC storage, and some of the tests like PCMark take storage into account. Other benchmarks like Cinebench and x264 are CPU only. To compare the Surface 3 against any other laptop we have tested, please use our Laptop Bench.
PCMark 8 from Futuremark has several benchmarks within it, all with the goal of simulating real-world use cases for each of the scenarios. It includes Home, Creative, Work, and Storage benchmarks. The workloads generally include both burst and sustained performance. The Atom can’t compete with the bigger Core pieces, but it is actually surprisingly close to the Core i3 Surface Pro 3. I think this is less about Atom and more about how handicapped Core i3 is with its lack of Turbo.
TouchXPRT 2014 is a benchmark that has a lot of burst workloads. The tasks are quick, but heavy, and it gives the processor a quick chance to cool off between each one so normally it is good about not running into throttling behaviour. The Atom processor is a long way off of the Core series here, with the exception of the i3 Surface Pro 3 which has no turbo capability. However there is a good bump in performance over the previous generation Atom in the HP Stream 7.
Cinebench is purely a CPU task, and it loves Instructions Per Clock (IPC) and frequency. There are two modes here with a single CPU run and all core run. It is still a long ways back of the Core i3 Surface Pro 3 on this test, and despite the Atom processor having four physical cores and the Core processors having only two physical and four logical cores, it is still not enough on the multithreaded run to really close the gap, although it does slightly. Looking at version 11.5 of this test, we have more data going back to older devices, so there are scores available from the ASUS T100 and there is a bump in performance compared to Bay Trail.
Once again this is a benchmark that prioritizes good IPC and frequency, along with multiple cores. The Atom struggles here compared to Core, which at this point should not be a surprise.
So clearly the new Cherry Trail CPU cores are not a giant leap in performance over Bay Trail, but like Haswell to Broadwell, there is a decent bump and the better manufacturing process helps increase overall performance due to the additional thermal headroom in the same power envelope. However when comparing it to the ARM competition, we only have a few data points but it does seem to be about on par with the top ARM CPUs at this time. Comparing devices across different operating systems is always difficult though.
Using the device day to day as a tablet though, performance was good. Yes, it could be better, and devices that use Core M are going to be able to run circles around Atom, but at the cost of additional heat. One of the nicest surprises of using this tablet was that it just never got warm at all, and the same cannot be said of any of the passively cooled Core M devices. Sure, when running very heavy benchmark loads, there was a bit of heat on the back, but it was never much more than around 30°C or so.
My experience was that when the Surface 3 felt slow, it was often not CPU bound but disk bound.

ingwe - Monday, May 4, 2015 - linkThis definitely looks interesting. If they would lower the price a bit or use faster storage, I would almost certainly buy.
hughlle - Monday, May 4, 2015 - linkAgree. As a device it is very compelling especially at that price point (i paid £480 for a 64gb ipad air 2 which could do pretty much nothing), however i'd only want one for the full functionality, and once you've paid out for that, it becomes quite a big argument as to whether you just pay the little more and go for the i3 sp3.
stefstef - Thursday, May 7, 2015 - linkno need to be unhappy. used apple hardware goes like hell on ebay. you might surely get a good price for it.
jim32 - Thursday, May 7, 2015 - linkI plan selling my iPad Air and getting the Surface 3 when the LTE version comes out. I need to wipe the dust from the iPad first though.
hughlle - Monday, May 18, 2015 - linkSold it a week later and took a 100 pound hit. 20% depreciation in a week is hardly good retention of value in my mind,
houkoholic - Monday, May 18, 2015 - linkIt's relative - with Android kit you usually lose 40%, and in 6 months more than 70%. So 20% is actually very good.
JRX16 - Wednesday, May 27, 2015 - linkOne week or 6 doesn't make much difference here. It would still be 20% which is excellent for anything used. What makes a difference is how close it is to the next release. It's not like a car with mileage, time of use doesn't make a big difference in price on these things. Condition does.
jaydee - Monday, May 4, 2015 - linkMy sentiments exactly. I feel there's a very small number of people who "need" a tablet/laptop all-in-one and are willing to sacrifice the best of either world, for an average tablet/mediocre laptop. I might be generous calling it an average tablet, just because of the lack of apps compared to android and Apple. If you're not going to hit at an attractive price point, then I'm not sure of your expectations.
With the $600 model, plus type cover and dock pushing $930 plus tax, why not an HP Spectre x360 8GB/256GB for $999? Is the portability, really worth giving up that much CPU/SSD speed, and RAM/SSD capacity, better keyboard and larger screen?
deathwombat - Monday, May 4, 2015 - linkLack of apps? It runs Windows! It runs about 8 billion apps written between 1995 and 2015. There is no large library of apps for any tablet.
smorebuds - Monday, May 4, 2015 - linkIkr. I just want to run my legacy Windows programs on a 10" screen using just my fingers. Can't do that on my sucky Samsung and Apple tablets. Who needs modern touch-friendly interfaces anyway...
