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.

    The demo is not full detail, its a playable test with lower image settings than the final game. Wait and see the final before we see what its "supposed" to look like. Reply

    If its really going to look like these pics then this performance review is useless, fps will drop by half. Im hoping you're right, but im betting epic simply polished up those pics to wow everyone. Reply

    Yah, i downloaded the demo. I was really disappointed. It gets boring really fast, like Quake Wars does. Nothing really innovating in terms of graphics, or fun factor, or "repeatability" over long term.

    I think TF2 ruined all these games. lol

    Despite being a mostly GPU-bound scenario, Intel still managed a 9% performance advantage over AMD at 3.0GHz.

    This text does not match the graphs posted, where the max gain was 4.4% for ShangriLa, the other two tests showed close to 0% difference. Analysis mistake, graph error, typo or what?

    Well since many of us today (yes even I bought one) has started to use Lappys and there is ones out now that where it is possible to play a view on how a 8600 GT w 512DDR2 and 256 DDR3 does would be nice and from 1680*1050 downwards. There are tons of these in lappys now so..

    Pretty please :)

    Just grab ATiTool from Techpowerup! and reduce the clocks of the XT.

    Interesting article, and as someone said you have a chart with text referring to AMD above it and the actual CPU numbers labelled as Intel. The last four charts on the clock for clock page say AMD yet list Intel CPUs.

    Last time I checked, ATiTool dosen't support the HD 2900xt. Only one that I know of is a buggy peice of software from AMD to change clock speeds. Reply

    Ati Tools works with 2900, I use it for my overclocking/fan contol.

    Ati Tray Tols does not work with the 2900. They are two different programs, Ati Tools is mainly for the things I use them for, while Tray Tools is a replacement for Catalyst Control Center.

    why bench the 2900 pro? is there a 2900pro which can't be clocked back to xt level? :)

    I'm glad i got a 2900pro for myself, regarding this benches i get 95% performance of a 8800gtx for 50% of it's price.
