Overall CPU Comparison

Because of the AMD performance issues we've encountered, even the Athlon 64 X2 6400+ isn't really competitive in our overall CPU tests. The 6400+ is marginally faster than the Core 2 Duo E4500, despite being priced higher than the E6750.

On the Intel side, the sweet spot for performance looks to be the Core 2 Duo E6550, or if you want to go cheaper, the E4500. Remember what we discovered about the impact of L2 cache on performance: you need around 20% more clocks to make up for a 2MB L2 deficit on Intel's CPUs, and about 35% to make up for a 3MB deficit.

AMD vs. Intel - Clock for Clock High End GPU Performance

    A very interesting article. I was wondering if you could pit Intel and AMD chips having the same L2 cache against each other? You can clock up the lower specced Intel part if need be. Since the game is L2 bound, this experiment would provide a more balanced outlook in a GPU bound or a clock-for-clock situation.

    If this is a beta demo (the multiplayer server browser does scream BETA! doesn't it?), does anyone know if there will be an updated 'final' demo? Further, will there be any Onslaught maps in said demo?

    Does AA work in the demo? I've downloaded it but due to Orange Box I haven't even bothered installing it.

    I'm mainly interested to know if the 8800GTS/GTX blow away the 2900XT or not once AA is enabled at 1920x1200 so that I feel better about my purchase of a 8800GTS 640 :)

    I dont think the purpose of reviews is to make you feel better about what you already bought. But hey, to each his own. Reply

    I appreciated the inclusion of some of the previous-gen cards here. Some of the recent graphics card reviews completely left them out, which essentially leaves me guessing as to how much improvement I might see by upgrading my graphics card.

    30 fps at 1920x1200 on my 7900GTX isn't great, but it's still at the lower threshold of playable, which is nice to know.

    What does this show us? At least for UT3 quad (vs dual) is rather a waste. If it shows so small and increase when its not gpu limited (ie low res 1024 tests) one wonders what will happen at higher res where the gpu is actually pressured.

    And even more so when your already crossing 100fps does it even matter?

    Now if quad helped us go from say 20 fps to 30fps I would say hell yeah its actually making a difference, but as is 155 fps to 186 fps...omg now I have to get a quad!

    Of course there were no tests at high res to compare core effect too.

    You have to remember that these were flybys with no activity. UT3 is making little of use of the extra cores now, but I'll bet that a quad core will flex its muscle once you add players, vehicles, explosions, and all the mayhem that goes along with a good UT match. Reply

    I thought the CPU tests were interesting, but largely useless! It reminds me of the UT2K3 flyby vs botmatch days. Why didn't Derek and Anand use Fraps to run a few botmatches. Sure the results aren't 100% repeatable, but if you run a couple botmatches on each setup and average the fps you'd get a fairly accurate result.

    I actually played with this, the frame rates weren't actually much different at all. You also have to keep in mind that in real world usage there won't be any bots, just other human opponents.

    Take care,

    just to underline this, running through a level with fraps yielded very similar framerates to the flyby tests.

    but the problem here is that even our run throughs were not very taxing. We can't add 9 thousands bots to a game and test anything, as they will cause problems with the run through adding variability and removing the possibility of repeatability.

    we don't have a doezen people we can start up a multiplayer game with and choreograph a scene that we can run every time we need another number.

    the real solution to the issue is the demo record and playback functionality. until we get that, flyby testing is the best we can offer and just isn't any better than a fraps run.
