Half Life 2: Episode One - Performance per Watt

Having just visited Valve to discuss their multi-core and multithreading plans, it's interesting to consider their claims that they are more CPU limited than GPU limited. The only one of these high-end graphics configurations that isn't completely GPU limited at the tested resolutions is the 8800 GTX SLI setup, which is CPU limited to approximately 230 frames per second. Apparently, Valve intends to make a lot more use of your CPU in the near future, since we're still testing Source engine performance without multithreading support.

Besides the impressively expensive 8800 GTX SLI, even the slowest of the tested configurations is able to run at 2560x1600 4xAA with reasonable performance. A single 7900 GTX might be a bit choppy, although disabling antialiasing should cure that problem, but some levels and areas in Episode One should have lower overall frame rates than this particular demo script. In that case, the single 8800 GTX once again ties X1950 XTX CrossFire for second place, with 7900 GTX SLI trailing by 15%-20%. 8800 GTS comes next, outperforming all of the remaining single card offerings.

    i'm sure there was a lot burried in there ... sorry if it wasn't easy to find.

    8800 gtx and gtx are both no louder than 7900 gtx. 1950 xtx still takes the cake for loudest graphics card around by a long shot -- especially after it heats up in a game.

    My comments in Daily Tech on this subject-

    More "G80" Derivatives in February R
    E: More info would be nice

    If you link VISTA -SANTA ROSA platform-Core2DUO(merom)CPU line up(T7300,7500,7700 models)then a matching Graphics card
    to complete the link.

    So a G80 for laptops/notebooks?

    The pairing of Intels Santa Rosa platform with Vista in the 2Q 07 is next big thing for the first tier notebook manufacturers & all they need is a matching G80 for this setup.

    Unquote-
    Nvidia currently caters to Desktop requirement/needs with the new G80 releases,wonder how the notebook/server versions will be-with Vista ofcourse.

    Vitual memory is probably a good thing for most cases, but in the graphics arena, this *could* potentially make for sloppy/ bad coding practises. Knowing a lot of game devers (some of which actually work for well known companies), I've heard them from time to time complain about maxing a 16x PCI-E pipe. What I'm trying to say here, is that while it would be a good thing for never having to run out of texture memory, but that system memory, and definately the swap disk can not hold a candle to the memory bandwidth that most Video cards are capable of. End result, is that you definately *will* get a performance hit. All this, and we already know the memory bandwidth capabilities of modern PCs, suffice it to say, the most we'll see from current systems is what ? 12-13K GB/s ? Even a 7800GS can do roughly 35 GB/s on card. A 7600GT ? 22GB/s ?

    Still I think Directx10 is a very good thing, and as I didnt read the whole article, perhaps a missed a little ? Reason being, I've been reading about Directx10 since April, and a friend of mine was privy to some of this information after an interview with ATI.

    I don't know how they threading really works, but its quite possible VM support is required in order to allow multiple threads to run without stepping all over each other,. Reply

    Sorry, should read "I don't know how THEIR threading works" Reply

    I don't know what is the problem but I'm really unable to see the images within the latest articles from Anand...Can anyone give me a suggestion? What might be the cause of that?
    The thing is I'm really, really interested in these articles and I need to see those images. Thanks

    Oh, er, then in the options tab of Firefox, (tools->options->content) check the "load images" check box ;) Reply
  • falc0ne - Thursday, November 09, 2006 - link

    well...it would've been simple but I'm afraid is not that...It might be the addblock extension from firefox, other than that I have nooo ideeea...Well I will use the IE tab option instead and load the pages using IE 7. Thanks anyway:) Reply

    Checked the exceptions list ? I know that firefox makes it really simple to block images from a site (to a point of being too easy). Reply
  • JarredWalton - Thursday, November 09, 2006 - link

    If you've got AdBlock on Firefox, press Ctrl+Shift+A and you can see what it's blocking. If it blocks the images.anandtech.com stuff, you can then see which RegEx isn't working right and edit that. Reply
