Relative Battery Life

The coup de grace for the UL80Vt is the battery life. Look at those charts and try to find anything else for $800 that can match the ASUS UL80Vt. (Note: the ASUS UL30Vt doesn't count, since it's pretty much the same laptop in a slightly smaller package.) Netbooks are able to offer competitive battery life, sure, but they're less than half as fast. The best-case Idle battery life tops out at just over 14 hours, but even a more demanding test where we load four web pages every 60 seconds - including one page with three Flash ads - still ends up at nearly 10 hours using the IGP and stock CPU speed. What's more, you can run with Turbo33 and the G210M and still get over 6.5 hours of web surfing.

We've dropped the other video playback tests, mostly because they're all very similar to the x264 results. HD DivX will last about 10-15% longer, and lower resolution videos would also improve on the results, but in general you can expect 5 to 6 hours of video playback with the UL80Vt.

The relative battery life is the final element, putting things into perspective. The UL80Vt has a higher capacity battery, so getting more mobility is somewhat expected. In the lowest power mode (IGP + stock CPU) the UL80Vt can provide nearly seven minutes per Wh, which is just slightly less than the ASUS 1005HA netbook. Turn on Turbo33 and battery life drops by about 10%. Running stock with the G210M enabled on the other hand results in a drop of 46%. Internet surfing with Turbo33 + G210M doesn't really change compared to stock with G210M, with only a 1% drop. The results here are in a test that happens to be more demanding than our MacBook testing, so the stellar battery life is even more impressive. Is it any wonder we're impressed with the ASUS UL80Vt? You get awesome battery life with reasonable gaming and application performance, all for just $800.

    I think you're not getting the whole picture

    Run it for an hour and then see the max temps then

    When mine arrives I intend to downclock below the 9800MGTX speeds ... for longievity.

    You may want to blur that picture of the bottom of the second laptop.

    Ummm... oops! Thanks.

    YOU'RE TOO LATE!!! Just kidding.

    I'm one of those people who has complained on the internet about the viewing angles, and I think your assessment is spot-on, because I came from an older laptop that had a higher-quality, but much dimmer, display. I do like that the UL80Vt's display is so much brighter than my previous laptop's, but the fact that such low-quality displays are commonplace nowadays is really sad. Companies will do anything to cut costs, I guess, but it's unfortunate that it's being done with such an important component. I guess most consumers don't care that much about the display quality, though, or else they wouldn't be able to get away with it. It would be nice if laptop manufacturers would at least offer the option of upgrading to a high-quality display. I would seriously have been willing to spend $1000 on a UL80Vt with a display on par with, say, the Macbook Pro or Dell Studio XPS (throw in a matte finish, an all-aluminum chassis, and a backlit keyboard, and you'd have the perfect laptop).

    Also, I notice in this article you said the graphics switch time takes about five seconds. I guess your fifteen second time to switch to the nvidia GPU went away when you reinstalled the old drivers? I'm still curious what might've been causing that.

    I think it may have been either drivers or something else; at one point I broke the GPUs with updated Intel and NVIDIA reference drivers. (They altered the support list to explicitly exclude hybrid GPUs after that, I guess.) Anyway, it's working fine now. If you're running a 3D app when you try to switch, it will blank for a bit and then you'll get an exclamation point on the NVIDIA icon, which is maybe what happened before... worst I've seen that I can confirm worked was around 10 seconds.

    Agree on the LCD, finish, etc. I've got a Photodon cover for a 17" laptop that I'm going to test out in a little bit and see how that compares to running a native matte LCD.

    What's the point of having a dedicated GPU in this laptop? It's too slow for gaming anyways. It's a thin and light laptop. Better to save 150-200$ to get a desktop computer to play games. The X4500MHD IGP will play 1080p movies just fine anyways. What else do you need? It's like people who want a dedicated GPU on an atom laptop or on their mac. Most of them will never make use of it.
  • DominionSeraph - Wednesday, December 16, 2009 - link

    WTH? It's the discrete graphics that make the UL80Vt interesting. Without it, there's no reason for it to have anything more than an Atom.

    Too slow for gaming? Jarred mentions playing Batman and Fallout 3 for several hours each. Sounds to me as though he was deriving entertainment value. Bet it plays WoW just fine, too.

    With laptops, there's always tradeoffs between price, performance, portability, and battery life. The UL80Vt seems to hit a sweet spot.

    And, honestly, for non-portable gaming, save yourself $600 and get a console.

    the UL30A is much more interesting

    Someone asked me to run DXVA Checker on the G210M to see what it says. Here are the results for the interested:

    NVIDIA GeForce G210M
    ModeMPEG2_IDCT: DXVA2, NV12, 720x480 / 1280x720 / 1920x1080
    ModeMPEG2_VLD: DXVA2, NV12, 720x480 / 1280x720 / 1920x1080
    ModeMPEG2_A: DXVA1, NV12, 720x480 / 1280x720 / 1920x1080
    ModeMPEG2_C: DXVA1, NV12, 720x480 / 1280x720 / 1920x1080
    ModeVC1_VLD: DXVA2, NV12, 720x480 / 1280x720 / 1920x1080
    ModeVC1_IDCT: DXVA1/2, NV12, 720x480 / 1280x720 / 1920x1080
    ModeWMV9_IDCT: DXVA1/2, NV12, 720x480 / 1280x720 / 1920x1080
    ModeH264_VLD_FGT: DXVA2, NV12, 720x480 / 1280x720 / 1920x1080
    ModeH264_VLD_NoFGT: DXVA2, NV12, 720x480 / 1280x720 / 1920x1080
    9947EC6F-689B-11DC-A320-0019DBBC4184: DXVA2, NV12, 720x480 / 1280x720 / 1920x1080
    B194EB52-19A0-41F0-B754-CC244AC1CB20: DXVA2, X8R8G8B8, 720x480 / 1280x720 / 1920x1080

    For the record, DXVA Checker fails to get any useful information when using the GMA 4500MHD.
