The 11-inch as a Windows Notebook

As a follow-up to our Nvidia 320M/MacBook Pro 13 article last week, I’ve been running our Windows test suite on the MacBook Air 11”. I, like Anand, have the lowest end 11”er, with 2GB memory and the 64GB SSD. This makes installing Windows an interesting proposition since after the two OS installs, you’ve got right around 30GB of free disk space to work with. My suggestion - if you plan on installing Windows and dual booting often, save yourself the headache and get the 128GB model.

The other quirk with putting Windows on the Air is that it must be done with a USB optical drive - no hard drive/thumb drive installs. Interestingly, my external optical drive wasn’t recognized as a bootable drive, so I had to run out and grab an Apple SuperDrive. Apple says that you just need an external DVD drive, without specifying the MacBook Air SuperDrive, but your mileage may vary.


Boot Camp Drivers are now downloaded from Apple's servers prior to the Windows installation

With the Windows install out of the way, we were free to test the living daylights out of it, and that we most certainly did. The 11” Air has the same 1.4GHz Core 2 Duo SU9400 as the similarly thin Dell Adamo 13. Months after we move to Arrandale ULV, leave it to Apple to bring the good old CULV platform back to relevance. As expected, Cinebench and the x264 encoding test gave us results around the same level as the Adamo and the rest of the old CULV gang. Versus the 13” MacBook Pro, you’re looking at roughly a 40% decrease in the CPU compute-heavy benchmarks, roughly equivalent to the reduction in clock speed from the 2.4GHz Pro to the 1.4GHz Air. Arrandale ULV notebooks, such as the Alienware M11x and its Core i7-620UM, are another matter entirely, with the newer architecture posting numbers nearly doubling the Air’s Core 2 processor.

The gaming benchmarks get a bit more interesting. We’re looking at the same GT 216-derived GeForce 320M that was in the MacBook Pro 13, with the same 450MHz core and 950MHz shader clocks. Based on the performance we saw out of the Pro 13, we know that the Air, even in 11” form, can still hold its own in games.

StarCraft II: Wings of Liberty

At low detail settings, the Air is pretty consistently 20% slower than the Pro 13, except in SC2, where they were roughly equal. Given that the GPU is identical and that both are using 256MB of the system’s DDR3 1066 memory, it is likely that the 1.4GHz Core 2 Duo is slow enough to put a bottleneck on gaming performance. It’s still a ways ahead of the ASUS Core i3/G 310M combo, and all of our games are playable at native resolution.

At medium settings though, the Air starts to fall off a bit. Where the MBP13 was borderline-playable, always between the 25-35 fps range, the Air is about 10% behind and makes it to the magical 30fps mark in STALKER, but nothing else. DiRT 2, Left 4Dead 2, Mass Effect 2, and StarCraft II all ended up between 22 and 26 fps, still faster than the G 310M, but not quite playable. Another interesting concern during gaming is heat. The Air isn’t the coolest notebook in the world, with idle temps hovering around 50C, but while running the gaming tests, I saw GPU temps rise up into the 70s. Nothing too alarming, but still pretty toasty and more than enough to get the fans spinning to the max.

But let’s put this all in perspective. This isn’t about just an 11.6” notebook that can game - the 11.6” M11x is the fastest gaming notebook under 5lbs, but even then it’s still a full two times heavier than the MB Air 11. The Air 11 shoehorns quite a bit of power into one of the smallest form factors on the market. Having a GT 216 core in an enclosure this small and being able to run these games at 40 fps at native resolution is definitely very impressive.

    I don't know any company that will do this -- HP and Dell require you to mail your machine in as well (unless you pay the extra $500 for the "Gold" replacement plans; an option only available on their most expensive "business" machines.) Often you have to remove the HD before you send it off or else yours might get "lost" (along with all the data on it.)

    Not that it's a great situation to be in; but this is an issue with many more companies than Apple. You'd still be out a machine.

    I own an MBP because it was the only machine available with both discrete graphics and better than 3 hours of battery life. The screen is also dynamite. Were there other machines that were cheaper? Sure. But Apple is the only company that makes a machine comparable to the MBP at any price.

    M11x has a descreet, and intergrated, and better then 4+ battery life, in home repair (they send out technicions)

    ill give ya the screen though. mac books do have nice displays.

    FYI if you have a Fry's electronics near you, when you get a notebook from them they will give you a loaner laptop till they finish fixing your system. If your paranoid about hardware failing in your system its something to consider.

    On another note the way that the macbooks are built makes it so that when you drop them you can do serious damage to the internals. Ive seen several MBPs that needed an external disk drive becaus the aluminum mill next to the dvd tray was made to thing and warped to the point where it would scratch any disk going in, or would not be able to load a disk at all.
  • Roland00Address - Wednesday, October 27, 2010 - link

    You only get a loaner if you bough Fry's Protection Plan that they offer not if you get it repaired under a manufacturer warranty (which Fry's will gladly service since they are an authorized repair center for many brands.)

    I second the aluminum mill being able to be warped it happened with my 08 macbook pro. That said many samsung dvd external drives are so cheap (and work with OS-X). I am seriously considering buying another ssd and a mounting mechanism in my macbook pro and then booting from the ssd.

    According to Anand:
    "The SSD isn’t in an industry standard form factor, although the connector appears to be either micro or mini SATA. Presumably 3rd party SSD manufacturers (ahem, SandForce partners I’m looking at you) could produce drop in replacements for the MacBook Air SSD."

    And... bingo!

    "The Air USB 3 Adapter gives you not only a brand-spanking-new 256GB module with a Sandforce SF-1200 controller, but a speedy USB 3.0 flash drive too -- which smartly doubles as the mechanism by which you move your old files over, as you can just transfer everything through the USB port. Once you're done swapping modules, the company says you'll see a 30 percent speed boost over the original drive, with reported transfer rates of 250MB/s on both sequential reads and writes. "

    Thanks for the link. Interesting.

    And matte screens are also available:

    All that is missing is an SD card slot

    It's a couple of very interesting machines, to say the least, but seem to suffer from much the same issues as previous generations.

    That said i'd be a pretty much perfect machine for me if it had;

    The traditional backlit keyboard.
    AMD's upcoming thin-and-light Fusion chips or an Intel Sandy Bridge ULV.
    USB 3.0 and HDMI ports.
    Matte screen options.

    Maybe the next version, eh?

    "In practice I found the 2008 13-inch MBA launched applications quicker (short bursts of full clock speed), but after prolonged use or completing CPU intensive tasks it was tough to tell apart from the new 11-inch. What's even more troublesome is that Apple's aggressive clock throttling went relatively undetected until now. This is something I'm going to have to devise tests for and pay more attention to in future reviews. Sneaky, Steve, sneaky."

    And this isn't the first time, Your Dell XPS 16's throttled like crazzy, and still do.
  • ipredroid - Wednesday, October 27, 2010 - link

    Anand, can 13in MBA run 30FPS on StarCraft 2? I realize this isn't a support forum... sorry for the lazy question. Thanks for the review. I saw the 11in MBA FPS) no 13in MBA :( FPS
  • khimera2000 - Wednesday, October 27, 2010 - link

    it is possible to do SC2. the memory bump would do you well if your considering running starcraft on the Air (RAM is shared with gpu and cpu) since you loose 256 megs of your 2 gigs to the video card and SC2 has a min spec of 2 gigs with a recommended of 4.

    it has performed respecabaly on the old air on low settings, so you should be able to bump up a couple of settings possibly getting up to medium with this new revision.

    but if your looking for 30FPS through i would go for low. with lots of units on the map in some games your system might lock up at the wrong time.
