Dell XPS 12 Tablet Performance Summary

We have a separate set of benchmarks for tablets, which focus a lot less on outright performance. Needless to say, the gap between Core i7 ULV and typical ARM and Atom tablet SoCs is pretty huge. Our tablet comparisons are going to use different devices, so let’s start with another table of the various tablets. You’ll note that the CPUs, Graphics, and Storage are all substantially faster on the Core i5/i7 devices. We've also tested the XPS 12 with multiple browsers, just to make things slightly more interesting.

Tablet Configuration Overview
Device CPU Graphics Storage Battery
Acer Aspire S7-391-9886 Intel i7-3517U HD4000 2x128GB SSD 35Wh
Acer W510 Intel Atom Z2760 SGX540 64GB eMMC 27Wh
Dell XPS 12 Intel i7-3517U HD4000 256GB SSD 47Wh
Microsoft Surface Pro Intel i5-3317U HD4000 128GB SSD 42Wh
Microsoft Surface RT NVIDIA Tegra 3 GeForce 64GB eMMC 31.5Wh

As we’ve noted in the past, while ARM and Atom can run a light OS like Android fine, and even Windows RT works well, that doesn’t mean we have anywhere near the same level of compute available compared to a full Core i5/i7 processor. And it’s not just about the performance shown in the above charts; start copying data to or from one of the Intel Core devices and you’ll notice a stark contrast compared to tablets with their slow eMMC storage and generally inferior WiFi and USB connections. Which is fine, considering the cost of the Surface Pro is the lowest of the Core offerings we’ve tested and still tips the scales at $900.

Intel has two paths going forward, and both are going to be quite interesting. On the one hand, Core gets updated with Haswell in the near future, which should lower power requirements and perhaps close the gap in battery life between Core and ARM/Atom. Whether they can actually close it or merely narrow it is the bigger question, but we’ll wait and see. On the other side of the equation, Atom will get a significant upgrade at the end of this year (or early 2014), and this will be the first time Intel has really put some effort into improving Atom performance. With a new architecture and a process shrink to 22nm, Intel’s codename Merrifield will be their most serious attempt at beating ARM and other SoCs and getting into more smartphones and tablets.

    Out of interest, what's the SSD inside your review unit?
  • JarredWalton - Friday, February 22, 2013 - link

    256GB Micron C400 mSATA -- table on the first page. :-p

    Really? I have a XPS 12 and it has a Samsung PM830 in it.
  • JarredWalton - Friday, February 22, 2013 - link

    Not too surprising -- Dell and other large OEMs usually like to have more than one supplier.

    Mine also has a Samsung PM830, but as others have pointed out, they do have sort of a part's bin. I believe all of the drives have similar performance though.

    Happens on many SSD equipped systems.
    I have an Ativ PC Pro with a PM830 while others (review systems and retail) have Sandisk U100. :)

    Mine also Has a Samsung PM830. I wonder if it region based or pre-production/final production makes a difference.

    I don't see the point of the 12 inch touch screen, if it doesn't also feature a decent digitizer for pen input.
    With pen input, I could have recommended this device to anyone who needs a medium sized sketch pad on the go, but like this it's just a small laptop with a useless gimmick.
  • nerd1 - Friday, February 22, 2013 - link

    With proper digitizer this would make a good note taking tool.

    Couldn't have said it better.

    If I'm to get a machine with a large touchscreen, that's portable, it needs to have an active digitizer and a good pen, and a slot for that pen.

    Otherwise, why would I buy it? It doesn't have a good graphics card (so bored of this trend of thin machines with onboard graphics, my goddamn Sony Vaio Z12 is 9.7mm thicker than this thing, yet has discrete graphics, and indeed a DVD writer, is actually smaller in X and Y dimensions yet has a larger screen, faster CPU, larger battery.. Come back when you can compete with that.)
