Dell XPS 12 Laptop Performance Summary

We’re taking the same approach to benchmarks that we used with the Acer S7 and Surface Pro reviews—which is to say, we’ll use all of our typical laptop benchmarks along with some of the tablet-centric benchmarks to round things out. Performance as you’d expect is basically on par with other Core i7 ULV offerings (e.g. Acer S7), so faster than the Surface Pro, substantially faster than any non-Core products, but worse battery life than ARM offerings. Given the size and weight, this is much more a part of the laptop with a touchscreen crowd as opposed to being a tablet with laptop aspects, so our primary focus will be on how it compares with other laptops. Here’s the quick overview of the base components for the various laptops we’re including. Note that at present, only the XPS 12, Acer S7, Surface Pro, and Vizio CT15 were tested with Windows 8; the rest were running Windows 7.

There aren’t really any surprises here; the XPS 12 performs right about where we’d expect. Acer’s S7 does come in slightly ahead in most benchmarks, which is interesting considering it’s thinner and thus cooling the chip (and enabling higher Turbo Boost clocks) should in theory be more difficult, but clearly that’s not the case. Whether it’s a lack of fine tuning for performance, minor differences in other components, or prioritizing quiet over fast, unless you’re really concerned about a difference of a few percent all of the i7-3517U Ultrabooks perform about the same. Actually, that’s not quite true, as Windows 7 models seem to hold a slight performance advantage in several tests as well (particularly battery life, which we’ll get to in a moment).

    There's a specific application I use on my Android tablet (that is also available on iOS) that has text versions of several thousand books and magazines, and it's all linked together (e.g. you'll see a reference to an article and you can click it to go there). All of the content is freely available on the Internet, but instead of staying within a unified full-screen app (with the ability to make notes and highlight material), you end up having a bunch of web pages open (which requires an active Internet connection) and you can't take notes directly or highlight passages, nor can you have any notes sync between devices.

    The best you can find in the Windows Store right now is an app that only has about five books, none of the magazines or other manuals, etc. I'm pretty sure the group that makes the apps for Android and iOS will have a Windows Store app in the future, but it might be a year or two (or it might be a month or two -- who knows?).

    When I use the XPS 12 as a laptop, none of the above bothers me much, but in tablet mode the fullscreen apps are far more important. I don't want to open web pages and type URLs if I don't have to; I don't always have Internet either. I don't have a GPS in the XPS 12, which makes getting turn-by-turn navigation directions impossible (sometime I can get on a $200 or less Android tablet).

    " Maybe it was all in my head, but those extra couple inches make a big difference. " (Page 3)

    Sure made me laugh :-)

    I have a 15z, and while I've been happy with it overall, the Cypress touchpad is proof Satan exists. I'd have hoped they got their act together in the 2 years since I got my machine, but the issues Jarred describes are very similar here, but to an even worse degree. I've only recently found a driver for another Dell laptop that has made it semi-usable, but for the most part, I find myself using a wireless mouse instead.

    I keep wondering where the sub 700 € ultrabooks powered by AMD hardware went?

    There was loads of talk about how OEMs would design one Intel "Premium" ultrabook which would then filter down into more affordable and probably similarly performing ultrathins with AMD hardware inside?

    Right now I'm looking to replace my wife's 13" Macbook Pro with something halfway decent, but considering the small difference in price and the unfortunately high amount of shortcomings I'm still inclined to think spending a couple of hundred more on an Air is the smarter choice given the standard she's used to from the MBP.

    Dell, HP, Asus and the other OEMs should be able slam Apple on price/performance but in this case they are more like equals.

    At least I'm happy to see highres displays starting to show up on these machines.

    Honestly I feel a 13" MBP equipped with the retina display would be solid value. User-upgradeable battery, RAM(2 SO-DIMMs instead of the stupidly soldered primary SO-DIMM) and SSD/HDD. Would kill all competition even if it was priced similarly to the 13" "MBP with retina display".

    It's the proletariat crap consumerism we have nowadays.

    Then we get the insane bottom dollar acquisition talks about Apples production takeover strategies, and what's left is the crap sandwhich everyone pretends to hate until they buy one, then the love never ends.

    If anyone does produce the correct device that isn't a crap sandwhich, the first and only thing anyone ever hears is it's a ripoff.

    Instead, we get a crap sandwhich, and an on the spot economics lesson by the posting would be CEO, who notes that 50 cent a bom is 50 million bucks.

    So expect many crap sandwhiches, forever.

    This Dell XPS 12 is by far the worst device that I have ever purchased. Touch screen stops working all the time, constantly unable to connect the wifi, cannot find hot spots, crashes at least once per week. Dell's solution is to continue reinstalling the drivers. Not what I expected for $1700. I've gone back to my $300 HP2000 which has turned out to be a much better purchase.

    If the touchpad or touch screen stop working on your XPS try touching the metal casing with your other hand... Here's a video of what I found happened with mine.

    I know I'm a bit late to the party with this review comment - but I would first like to point out that prices have started coming down on the XPS 12. I got an 8GB i7 model with 250GB SSD for $1300, and they are dropping even further.

    As a Network Analyst/Engineer/Duct Tape Master, I am constantly in wiring closets, in meetings, and on the go. The XPS is what I would call a perfect blend of Laptop/Tablet. For MY purposes, it works better than any other hybrid out there. One reason the flip screen works so well is for documentation - I can use it in full tablet mode, or just flip the screen around easily go through large PDF's in either portrait or landscape using the base (keyboard) as a prop. It is sturdy, unlike most tablet stands, were I can navigate without worrying about the unit flopping over.

    There are some glaring omissions on what could be a grand slam of the jack of all trades laptop. GPS is not included, which is disappointing to me. It's not a deal breaker by any means, but the cost of adding GPS is negligible these days in a modern device. Also, as mentioned, there is no digitizer pen capability with the XPS 12. I don't find that as crucial. It would be nice, but it does reduce the sensitivity of the touch screen - which the XPS is one of the best touchscreens I've ever used. I just ordered a Jot Pro for note taking - but even that will be used sparingly.

    My last con is the touchpad - it is ill conceived to say the least. I've had all the mentioned issues - and it has horrible response. Button presses often go amiss. One thing I will say, it has gotten me used to the touchscreen, because I'm now constantly trying to use gestures on my non touch screen Mobile Precision laptop.

    I highly recommend this hybrid to anyone that needs flexibility between a laptop and tablet. Especially IT pro's that need to between the office and the field. (The field being wiring closets or datacenters). To me, Dell hit a triple with this. It is so close to being a home run, but I'll take it given the current generation of Tablet/Laptops hybrids.

    I don't mind the price of this because the specs are really good. However, the bulk worries me. In order to get a tablet with 256 gigs of storage and a 1080p screen, it seems like just about everything I can find are these sort of thick hybrid/convertible units. Sony's Duo slider unit comes to mind.

    What I would really like to see is something with a detachable keyboard, like Samsung's 700T tablet, which has the perfect style, but with 256 gigs of storage.

    I have not found the perfect Windows 8 tablet yet, but the XPS 12 come really close.
