Surface Pro as a Tablet

If you can get over the bulk, Surface Pro is easily the fastest tablet on the market today. Apple has done a great job of making relatively slow hardware feel very fast with iOS, but Surface Pro brute forces its way to the top. Web pages load quicker than on any ARM based tablet and multitasking is just awesome on the device. This is where the power of Intel’s Core microarchitecture really comes into play.

Since the introduction of the 3rd generation iPad with Retina Display several folks have pointed out to me that UI frame rate isn’t always so smooth on the device. I personally never noticed because I found that most of the competition was even worse, so it always seemed relatively smooth to me. After playing with Surface Pro however and going back to even the 4th gen iPad all of the sudden frame rate stutters are much more noticeable. Playing around with Bing maps on Surface Pro vs. RT is like night and day. Even if you compare scrolling and zoom performance to native iOS maps on the iPad 4, Surface Pro wins out.

Scrolling in web pages, application install time, file copy time, everything is just significantly faster on Surface Pro than on any competing tablet. Oh, and it boots (from full power off) in less than 10 seconds. It’s really the combination of the great CPU performance and fast SSD that deliver the responsiveness of the Surface Pro.

We’re still lacking good cross-platform performance tests, but there are a few browser based benchmarks that I can use to highlight just how much faster Surface Pro is compared to anything ARM based on the market today:

SunSpider Javascript Benchmark 0.9.1 - Stock Browser

SunSpider is our tried and true quick js benchmark, and here we see huge scaling as we move to Intel's Core i5. Regardless of browser used you're seeing a significant improvement in performance that directly translates to faster web page load times.

Moving on we have Kraken, a seriously heavy javascript benchmark built by Mozilla. Kraken focuses on forward looking applications that are potentially too slow to run in modern browsers today. The result is much longer run times than anything we've seen thus far, and a very CPU heavy benchmark:

Mozilla Kraken Benchmark

Even when handcuffed by modern IE10 you're looking at almost twice the performance of the Nexus 10. Level the playing field with Chrome as a browser and now Surface Pro completes the test in a bit more than 1/8 of the time of the iPad 4, or 1/4 of the time of the Nexus 10.

Surface Pro manages to deliver almost 5x the performance of the iPad 4 here.

We have one last web-based benchmark: WebXPRT by Principled Technologies (PT). WebXPRT measures performance in four HTML5/js workloads:

Photo Effects: Measures the time to apply effects to a set of six photos. The filters are Sharpen, Emboss, and Glow. WebXPRT applies each filter to two photos. This test uses HTML5 Canvas 2D and JavaScript.

Face Detect: Measures the average time to check for human faces in a photo. WebXPRT runs this test on five photos and uses the average time to calculate the final result. This test uses HTML5 Canvas 2D to get access to photo data. The detection algorithm is implemented in JavaScript.

Stocks Dashboard: Measures the time to calculate financial indicators of a stock based on historical data and display the result in a dashboard. The calculations are done in JavaScript, and the calculated stocks data is displayed using HTML tables and Canvas 2D.

Offline Notes: Measures the time to store notes securely in the browser's HTML5 local storage and display recent entries. This test uses using AES for security.

We're reporting the overall score after all tests have been run:

Next up are another set of benchmarks from PT, but unlike the WebXPRT suite these tests don't run in a browser. Once again we're looking at performance in a handful of tasks designed to stress the CPU. Here the performance advantage continues to be quite significant. While Surface RT and the other Windows RT/8 devices still feel a bit sluggish, I have no performance complaints whatsoever about Surface Pro:

TouchXPRT 2013 - Photo Enhance

If I had any complaints about using Surface Pro as a tablet outside of weight, they’d be about Windows 8. There are still far too many bugs and quirks in the OS that just don’t make sense. I’ve outlined some of my issues with Windows 8 before. I think the UI works just fine for a tablet, it’s just the unfinished touches that need attention. For example, having to gesture in modern IE10 before being able to switch between tabs seems silly.


This still happens way too often in the Windows Store, no indication of what's going on just a blank screen

On the bug-front, all too often I’ll wake up the system only to have the lock screen upside down. And despite all of the extra performance under the hood, the time from when you hit the power/lock button to when something appears on the screen is just longer than on an iPad or Android tablet. We’re not talking several seconds, but it’s still noticeably longer.

    Because most people who are hardware reviewers see red flags only.. $899.. And the rest of the review is based on that..

    Surface Pro is the MOST productive tablet available. BY FAR. Why? because it's a PC in tablet form.

    Has there been any talk/musings about a hybrid APU featuring both an Atom and the traditional Ivy Bridge/Haswell cores on a single die??

    I believe your last podcast mentioned the Octus or Octal or whatever in the ARM space. Seems like for a powerful, but mobile Surface Pro, this is a no brainer. If I want to switch to battery life mode and get 9-10 hours, Win 8 can be made to only schedule on the Atoms and power gate off Haswell.

    Or does Intel really believe they can get Haswell and beyond into the power space of Atom/ARM??

    The review said that in power saver mode it runs at 800MHz. Can you force the low clock rate? If so, how would performance and battery life compare to ARM?
  • Netscorer - Wednesday, February 6, 2013 - link

    That's actually a good point. Anand delivered performance charts based on fully powered core i5 and battery results based on clocked chip at 800MHz. Many people don't realize that you don't get both (and review does not help to highlight that difference) - either you are using it in light mode for stated hours or you run some complex program and have to be always connected because CPU would seep power like a thirsty kid on hot afternoon.

    I also want to see how much battery life you can get on power saving mode. Peformance would also be nice, but it's predictable I guess, So, please, battery life on power saving mode. I registered to post this comment.

    Anand, are you guys planning on reviewing the ASUS TAICHI21? The base model is $1300, which is only $170 more than the Surface Pro with a Type Cover, and it solves the lap usage problem while maintaining mostly the same battery life. I'll grant that it's a bit heavier, but I've got one and I absolutely love it. Those screens are just stunning.

    That was just another scam by InHell.

    The Pro seems, in this and other reviews, to always get the unfavorable comparison on each dimension--it's not a thinner, lighter thin-and-light, it's either a heavy, bulky iPad or a bit slow for the most advanced games, depending on context.

    Microsoft seems to be betting that some folks can live with tradeoffs to get a super portable fully-functional computer. I really hope they're right; I'd like my next computer to be like this, and I'll have more options if this (or something like the Acer W700--I'd happily lose the pen and apparently unreliable covers) does well.

    Hi Anand,

    Would yod mind posting up a screenshot of the Surface Pro's desktop in full 1080p resolution? I'm curious to see how an application like Visual Studio 2012 would look like.

    My hopes for this device were to be my go-to device for sitting on my couch writing code after I put my kids to sleep...

    Thanks in advance.
  • spencer.p - Wednesday, February 6, 2013 - link

    I am curious, Anand, if you can test to see if the Surface Pro works with the widi standard that Intel is pushing out and if it's also possible to get the Surface Pro to a 30" dual-link DVI monitor via one of those mini-displayport to dual-link DVI adapters. I am really curious if the Surface Pro will be able to meet my use case.
