Still Great Battery Life

With all the gaming performance on tap, and despite the lack of Optimus Technology, the M11x still manages to deliver great battery life results. Alienware puts an 8-cell 63Wh "Prismatic" battery in the M11x, which is quite large for an 11.6" chassis. Even better is that Alienware manages to keep the chassis looking clean, as opposed to designs like the Dell 11z where the large 6-cell battery juts out the bottom. We calibrated the LCD for ~100nits as always and found that a brightness setting of 60% (three steps down from maximum brightness) gave us the desired result.

Battery Life - Idle

Battery Life - Internet

Battery Life - x264 720p

Relative Battery Life

The best-case results will give you typical CULV run times: over 4.5 hours of x264 playback, 7+ hours of Internet surfing, or just shy of 9 hours of idle battery life. If you don't like fussing with the BIOS, we suggest you run the M11x at the overclocked setting all the time; you still get over four hours of x264 video playback, 6.5 hours of web surfing, and 7 hours of idle battery life. Try that with any other "gaming" laptop and you'll likely end up disappointed. Relative battery life puts the M11x just slightly behind other 11.6" CULV laptops (Acer 1810T and Dell 11z) and on par with the Gateway EC54. Again, we really like switchable graphics and Optimus, as it allows users to get the best of both worlds… except Optimus appears to be the way of the future since you get better driver support (at least that's what NVIDIA is saying right now—we'll confirm when we see the next public Verde driver).

Of course, if you want to play games without plugging in—which means using the GT335M, naturally—you're going to get significantly less battery life. We conducted a gaming battery life test as well, with the CPU overclocked. The M11x managed just over two hours (126 minutes) before shutting down, though it did provide the same great gaming performance in the interim. If you need to play games for 90 minutes or less on your daily commute, and you don't mind the strange looks on the faces of your fellow passengers, the M11x will provide a nice outlet. However, it works better for gaming if you have ready access to an AC outlet, in which case the battery is just a safeguard against losing your progress with the power goes out.

    Thanks so much for your comprehensive review, Jared. I've read a bunch of reviews for the m11x, but they're always mixing up overclocking, non-overclocking, GPU enabled, GPU disabled, and a bunch of other factors that make it extremely difficult to discern how the thing actually performs.

    Your review, on the other hand, covers all the bases thoroughly, and answers every single question I have!


    Well, one question left - I wonder when the 335M will be made available in other laptops? I'm interested to see what ASUS and other manufacturers could do with it....

    I'm guessing it's just a question of laptop manufacturers asking for chips from NVIDIA. There are lots of options so they can take their pick. For example, a great alternative that's not from NVIDIA would be the Radeon Mobility HD 5670... we'll show you why soon enough. :-) Reply

    Thanks for the review and only confirms my initial thoughts that this tiny notebook is hardly qualified to be a gaming computer. I knew it was all marketing hype. I don't enjoy gaming in low res, thank you. Reply

    As an M11x owner your review pretty much sums up the M11x pretty well. Once I got my Alienware unpacked and setup I immediately started loading some games onto it and was pleasantly surprised. I've only played Wolfenstein and Call of Duty: Modern Warfare, but they look good and are definitely playable with no problems. Will it play Crisis as well as my desktop? No way, but I don't expect it to either.

    I found the keyboard tight, but I got used to it quickly. I don't really care about the lack gigabit ethernet or optimus, however I do find the screen kind of glossy. Glossy screens are a problem with every other laptop manufacture on the planet, so I don't blame Alienware directly.

    One thing that really surprised me when I opened up the packaging was an actual Windows 7 install disk was included. The system manual was actually useful as in it gave graphical pictures on how to replace the hard drive, memory and battery. Granted I don't buy that many laptops but I haven't seen either these things included with a computer since 2002.

    There's a laptop for everybody and this one will suit some and not others. The angular looks and the system lighting are the greatest thing since sliced bread IMHO, but I'm sure others will disagree. I'm in the military and deploy fairly regularly so small form factor and power are crucial when your trying to squeeze hundreds of pounds of stuff into small bags. This computer is almost perfect for a deploying gamer and I'm sure I'll be testing that out soon enough. Anyway, good review even if I thought you were being just a little bit picky.

    The lack of Optimus is more a driver concern than anything. The old push-button switchable graphics probably won't get more than token driver support from nvidia, while they're pushing Optimus very hard--Optimus drivers will soon be included in the Verde package.

    Personally even if I had Optimus, I'd tell it to change GPU switching to manual since there's a lot of weirdness with some apps when you let it try to decide on its own.

    As an M11x owner I thought I'd just comment/question on a few things:

    1. I know there are two different LCD panels(one a bit brighter, one a bit better contrast) used and both pretty much suck ratings wise, yet I find mine looking more than good enough for me. My 24" LCD for my desktop is rated much better all around(double M11x quality or more) but I honestly can't tell much of a difference between it and the M11x screen. So while I do understand better is better, I see why the LCD is the corner that is cut most often in a notebook.

    2. My fan never turns on unless I am using the 335M. Once I use the 335M it kicks in instantly and can get loud if you don't have sound(games, music, etc) going.

    3. How well does GPU assisted video editing work? I know you said fast but does it make up for the weaker CPU? I am planning to use it on vacation most likely once I get around to buying a camcorder.

    Overall I think the M11x is sorta for people who want something as small as possible that can game well and have big battery life in standard tasks like browsing. I got it for traveling/mobility myself, I liked the better performance in bigger notebooks but I knew I their size or extra weight would defeat the purpose. I almost never use the 335M for gaming unless I am going to be sitting plugged in for a while so it works perfect for me.

    As far as the fan, either my unit is flaky or your unit is better than most. Fan noise levels top out at 36 dB, which is certainly lower than a lot of laptops, but it kicks on ALL the time for me.

    Video editing is generally far more CPU bound than video encoding, and here the CULV processor will be a definite bottleneck (at least AFAIK... maybe someone can recommend a good video editing package where the GPU will make a difference). Since you asked about video, though, I did a quick check of Badaboom with the GT335M.

    The result (using the same test as here: http://www.anandtech.com/show/2878/9) is an encoding speed of 53.1 FPS on the GT335M. With the CPU using TMPGEnc, we got a result of just 22FPS. A faster CPU can surpass the GT335M, but we're looking at quad-core Kentsfield before we get to the crossover point.

    Finally, in regards to being picky, I admit to being a bit occupied with my wife and pending birth. LOL. But I tried to make it clear where the flaws are and where the M11x excels. If your primary criteria is getting a smaller laptop with good battery life that can still play games, it's awesome. If you're concerned about drivers, I'm not convinced. The LCD is also a weak spot, but it's no worse than 98% of laptop LCDs, so that's almost a wash. Optimus and an i7 ULV processor would have been a silver award for sure.

    When I first heard about the M11x, I was really pretty shocked Dell didn't use the Arrandale ULV processors. A Core i5-520UM or i7-620UM would have been perfect in this (along with Optimus), but it appears the problem was that Intel did not have the ULV chipset with support for discrete graphics available at the time the M11x was ramping up. It wasn't until later that I saw Arrandale ULVs with a discrete graphic option... and right now, only one of the MSI X-Slim is the only one I can think of. Reply
