- Surface Pro 3
Earlier this Summer Microsoft released Surface Pro 3, a fully equipped Haswell ULT based tablet in a chassis that was much more in line with what you'd expect from a tablet. From a hardware standpoint, Surface Pro 3 is the chassis design that Microsoft needed from the very start. If you've ever been tempted by the Surface Pro story, the latest model was bound to push you over the edge.
Unlike previous generations however, Microsoft delivered multiple CPU/GPU options with Surface Pro 3. The device's price range extends both lower and higher than any prior iteration. While the original Surface Pro launched at $899 and $999, the second version offered increased storage options that drove the max price up to $1799. Surface Pro 3 starts at just $799 and can be configured at up to $1949. In our review we were sampled one of the launch versions of the tablet, a $1299 configuration featuring Intel's Core i5-4300U. Until next month the Core i5 models are the only ones available, however starting on August 1st you'll be able to purchase cheaper Surface Pro 3s with a Core i3-4020Y or more expensive versions with a Core i7-4650U.
We just got our hands on the $799 entry level Core i3 configuration and are in the midst of a full review of the device. Battery life testing alone will take a few days, but I wanted to share some of my initial performance data since there is a pretty substantial difference between the Core i3 and i5 models. For a quick refresher, this is what the Surface Pro 3 lineup looks like:
|Microsoft Surface Pro 3 Configuration Options|
|CPU||Intel Core i3-4020Y||Intel Core i5-4300U||Intel Core i5-4300U||Intel Core i7-4650U||Intel Core i7-4650U|
|Frequency Base/Max Turbo||1.5GHz/-||1.9/2.9GHz||1.9/2.9GHz||1.7/3.3GHz||1.7/3.3GHz|
|GPU||Intel HD 4200||Intel HD 4400||Intel HD 4400||Intel HD 5000||Intel HD 5000|
|GPU Frequency Base/Max Turbo||200/850MHz||200/1100MHz||200/1100MHz||200/1100MHz||200/1100MHz|
|Storage||64GB SSD||128GB SSD||256GB SSD||256GB SSD||512GB SSD|
To hit the $799 price point Microsoft went to a 64GB M.2 SATA SSD. Interestingly enough, the CPU doesn't actually save Microsoft any money. The Core i3-4020Y carries the same 1000Ku price as the i5-4300U ($281). The Y at the end of the part number implies a Haswell ULx SKU, the only Haswell type to ship with a SDP as well as a TDP rating. Even using the same workload, the Y-series parts weigh in with a lower TDP than the more typically used U-series parts (11.5W vs. 15W). Given the substantial reduction in chassis thickness, I suspect the Y-series parts may have been a better fit for the design to begin with.
You do give up performance in the process however. Since this is a Core i3 processor Intel disables turbo boost in addition to lowering the base frequency of the chip in order to hit its 11.5W TDP. At 1.5GHz without turbo, peak single threaded performance could be as little as half of the Core i5 models. The GPU performance story is arguably more interesting. Although there's a decrease in max GPU turbo, I wonder if the lower TDP may help improve sustained performance in games. I ran a few tests to see how things change with the move to a Core i3. Let's start with a look at the CPU.
Single/Multithreaded Performance - Cinebench 11.5
One of the benefits of a Surface Pro is the ability to run heavy PC workloads just as well as lighter tablet workloads. The device can behave as a tablet, notebook or even a desktop. We'll start with Cinebench 11.5, an offline 3D renderer that is largely CPU bound. The single threaded incarnation of this benchmark should give us a good look at the worst case scenario performance delta between the Core i3 and Core i5 Surface Pro 3s:
Without the ability to boost above its 1.5GHz base clock, the Core i3-4020Y comes in substantially slower than the Core i5-4300U model. It turns out a 1.5GHz Haswell core is around the performance of a 2.3GHz AMD Piledriver core.
With both cores (and all four threads) active, the gap between the Core i3 and Core i5 parts doesn't really shrink any. It's clear that if you're after running heavier PC workloads on your Surface Pro 3, you'll want to spring for the Core i5.
General Usage Performance - PCMark 8 v2
Cinebench may overstate the difference you'll see between the $799 and $999/$1299 models in regular usage, so we turn to PCMark 8 v2 and PCMark 7 to give us a better look at real world performance differences when running lighter tasks. PCMark 8 v2 runs through a bunch of usage driven application scenarios grouped into home, creative and work usage flows.
From Futuremark's description of the Home test:
"The PCMark 8 Home benchmark includes workloads that reflect common tasks for a typical home user. These workloads have low computational requirements making PCMark 8 Home suitable for testing the performance of low-cost tablets, notebooks and desktops. Home includes workloads for web browsing, writing, gaming, photo editing, and video chat. The results are combined to give a PCMark 8 Home score for your system."
A 20% increase in performance is what the Home suite shows for the i3->i5 upgrade, and that seems fairly reasonable. The Core i3 model ends up performing quite similarly to the original Surface Pro, but in a much more appealing chassis.
Next up is the Creative test:
"The PCMark 8 Creative benchmark includes workloads typical of enthusiasts and professionals who work with media and entertainment content. With more demanding requirements than the Home benchmark, this benchmark is suitable for mid-range computer systems. PCMark 8 Creative includes web browsing, photo editing, video editing, group video chat, media transcoding, and gaming workloads."
The creative suite shows a larger 34% advantage for the Core i5 vs. Core i3. Once again the i3 performs within 10% of the original Surface Pro, but for heavier use cases the Core i5 is necessary if you want Ultrabook/Macbook Air-class performance in a Surface Pro 3.
Finally we have the Work test:
"The PCMark 8 Work benchmark test measures your system's ability to perform basic office work tasks, such as writing documents, browsing websites, creating spreadsheets and using video chat. The Work benchmark is suitable for measuring the performance of typical office PC systems that lack media capabilities. The results from each workload are combined to give an overall PCMark 8 Work score for your system."
Here we see another 33% advantage for the Core i5, and surprisingly enough a pretty similar gap between the Core i3 SP3 and the original Surface Pro. It's really the lighter workloads that will understandably show less of a gap between the i3 and i5.
I'm also including PCMark 7 results which tend to fall in between the PCMark 8 v2 results, here showing a 26% advantage for the Core i5 model.
GPU Performance - 3DMarks
I'll split our look at PC GPU performance into two sections, first let's look at peak theoretical performance using 3DMark. The Core i5-4300U has a 29% higher peak GPU clock compared to the Core i3-4020Y so we could see gains of up to that in any GPU bound scenario.
The heaviest 3DMark 2013 test here is Fire Strike and we see a 27% advantage for the Core i5 vs. Core i3 model. Note that the i3 is still substantially quicker than the original Surface Pro.
In lighter graphics workloads the gap narrows, with the Core i5 model holding a 21% performance advantage over the Core i3. The entry level Surface Pro 3 still delivers substantially better GPU performance than the original Surface Pro.
The Ice Storm test seems to provide a good mix of CPU and GPU bound work for the platforms, which contributes to the largest gap we've seen thus far in our GPU tests of 30%.
Looking at 3DMark 11 there's virtually no performance difference between the two platforms. This ends up being a bit more strenuous of a test, likely forcing the Surface Pro 3 into a thermally constrained situation where GPU clocks can't remain at max for long.
PC Gaming Performance - Dota 2
In our original Surface Pro 3 review I asked Ryan Smith to put together a reasonable Dota 2 benchmark to better illustrate what a prolonged light graphics workload would do to the system. In the end I found that the thermal constraints and default fan profile of Surface Pro 3 can contribute to lower sustained performance vs. Surface Pro 2. Our Dota 2 benchmark did a great job of showcasing a real world scenario where SP3 could be appreciably slower than SP2.
With the Core i3 version I was curious as to whether the better binning and overall power reduction would result in a device that would be able to sustain a higher level of performance for longer than the Core i5 version. I ran the Core i3 model through the exact same Dota 2 workload and came away with some interesting results:
Whereas the Core i5 model couldn't make it through a single run of our test without stepping down in performance, the first run on the Core i3 system came very close to the performance of the Surface Pro 2. Subsequent runs however did drop to performance similar to the Core i5 model, although the i3 is able to sustain higher performance.
My original review sample featured a 256GB Samsung PM851 (an OEM version of the SSD 840 EVO) SSD. The $799 Core i3 model I received features a 64GB SSD, and in my case it's an SK Hynix drive. SK Hynix is a fully vertically integrated NAND and controller manufacturer thanks to its acquisition of Link A Media. The HFS064G3AMNB-2200A in my Core i3 based Surface Pro 3 uses a LAMD 87800 controller like the Corsair Neutron/Neutron GTX and Seagate SSD 600 series of SSDs. Both of those drives proved to be highly consistent performers, even when running in a full state. I'm not sure if all 64GB models will use the Hynix/LAMD drive, but given how little free space is available on the 64GB drive I would hope as many of them are this configuration as possible. After installing my relatively limited suite of tests for this review I had 10GB free on the device, with Windows telling me that another 10.5GB was taken up by things I'd installed.
PCMark 8 v2's storage test gives us a good look at high level performance, and here there's no real difference between the 64GB and 256GB drives:
However this is a bit of an optimistic look, I turned to Crystal Disk Mark to give us a quick idea of peak sequential and random performance:
64GB Hynix SSD (left) vs. 256GB Samsung SSD (right)
Testing over a 4GB span there's clearly a reduction in sequential and random IO performance but both are quite solid on the 64GB model. I don't expect users to store large files on a 64GB Surface Pro 3 so the reduction in sequential read/write speed isn't a huge deal. Overall I'm quite pleased with the performance of the 64GB drive in my i3 sample.
Last but not least, I wanted to look at how the Core i3 would perform in a lighter set of benchmarks we typically run our ARM based tablets through. Surface Pro has always ended up at the top of these tests, but we've never had a Surface Pro clocked as low as the Core i3 SP3. At 1.5GHz this also gives us an interesting look into the IPC comparison between Haswell and Apple's Cyclone cores as the iPad Air runs at a similar frequency (1.4GHz). Do keep in mind that there's a fairly large difference in platform power between a Surface Pro 3 and an iPad Air however.
The light workload js benchmarks end up being great measures of single threaded performance, which is why we see such a substantial difference between the Core i5 and i3 models here. That being said, the i3 based Surface Pro 3 still ends up being faster than any of the traditional ARM tablets. The iPad Air comes dangerously close though.
Kraken tells a similar story, although here we see a larger gap between the i3 based Surface Pro 3 and the iPad Air.
The GPU performance story is no different than in our earlier tests. The i3 model takes a hit, but GPU performance is understandably much better than any other tablet you'd come across.
Subjectively, the entry level Surface Pro 3 feels pretty quick. Even running at only 1.5GHz, a pair of Haswell cores are plenty fast. The real question is whether or not the extra $200 is worth the increase in performance. For anyone looking to use the Surface Pro 3 like a real PC and less like a tablet, the $200 Core i5 upgrade is a wise investment. Lighter tasks and more tablet oriented usage models however may not merit the extra expense. In a lot of lighter tasks we're looking at a 20 - 30% advantage to the Core i5 for a 25% increase in system cost. Ultimately I feel like the increase in storage capacity in addition to CPU performance may be what really justifies the larger expenditure for users who don't necessarily need the extra CPU performance.
The big unanswered question at this point is whether there are any gains in battery life. I'm working on producing that data now and I'll post a follow up once it's complete. Updated: Battery life results are in.

Trixanity - Wednesday, July 23, 2014 - linkWill you look at the i7 model as well?
Bultreys - Wednesday, July 23, 2014 - linkYes, I'm most keen to see a performance/heat breakdown of the i7 before I pull the trigger on any of these SP3 models.
lorribot - Wednesday, July 23, 2014 - linkRetail price difference between a 256GB and 128GB SSD mSATA drive is around $60. $GB ram to 8GB ram is $20, total $80. Microsoft seem to think it is $300.
It seems that MS have drifted in to Apple land with thier pricing and quite frankly either their purchasing department are looking a bit inept or they have succumbed to the marketing men.
But it is to Anadtech's eternal shame for not calling out this huge rip off in pricing.
kyuu - Wednesday, July 23, 2014 - linkExcuse me, but please point me to the outfit that builds tablets and sells component upgrades at-cost? I'll wait.
Yes, obviously there is a mark-up. That's how the business model works on these things (and it's not just Microsoft or just Apple): margins are slimmer on the lower-specced models, and the margin grows on the higher-specced models.
Compared to Apple, Microsoft's markup is quite reasonable, really. To go from an iPad Air with 16GB of NAND to the 128GB model, it costs $300. That's $2.68/GB. To go from 128GB to 256GB with the Surface Pro 3, you also pay $300 more. That's $2.34/GB. And that's for an actual honest-to-god SSD, whereas in the iPad we're talking about much, much cheaper eMMC NAND. *And* you get the extra 4GB of RAM on top with the Surface.
Would it be swell if it was cheaper? Of course. If you don't see the value proposition, then don't pay. There's nothing for Anand to call out here.
chizow - Wednesday, July 23, 2014 - linkYep I really like the options MS put out there with their SP3 line. It's never a price bump just for storage until you get to the i7 models I believe. You get a faster CPU and more storage going from $800 to $1000, and more RAM and more storage going from $1000 to $1300. Definitely hits a lot more target users that way.
Impulses - Thursday, July 24, 2014 - linkI actually thought that made more sense than the usual breakdown for these things, and the $800 price point is bound to tempt away some buyers that were looking at $600 budget laptops...
name99 - Thursday, July 24, 2014 - linkYou do understand that the point of this variable pricing is to be able to charge richer customers more? That extra money, in turn supports the R&D that allows poorer customers to get their devices cheaper.
This is not some massive moral matter, unless you happen to believe that the world as a whole, and MS (or Apple) in particular, ought to privilege wealthier buyers at the expense of poorer buyers.
skiboysteve - Wednesday, July 23, 2014 - linkRule of thumb at my company is 4x price for 1x cogs (cost of goods sold). This pays for engineering time, manufacturing expenses, storage, shipping, etc.
Every time someone posts the nonsense about selling goods at cost i wonder what they do for a living
Cygni - Wednesday, July 23, 2014 - linkAt that price, I would still rather have a Macbook Air and bootcamp if i wanted Windows...
Surface still seems to be an answer to a question the market wasn't asking in the first place.
Drumsticks - Wednesday, July 23, 2014 - linkThe surface line consists of 2, at most 4 SKUs. The Mac line consists of at most 9 SKUs, almost all of which have vastly higher pricetags. Revenue on the Surface line (again, which ranges from $500 to $1500, now $2000) was 500 million, while the Mac line put out 4.5B.
The surface line might not be selling well, but given that + the significantly higher price of almost every unit in the mac lineup, it's certainly not doing so poorly that the market isn't asking a question of it.
