Why is the 4870 X2 the slowest out of all the graphic cards tested for CoD4? According to Hardware Canucks, the 4870 X2 absolutely destroys the competition. At 2560X1600 on highest detail, 4X AA and 16X AF, they got average frame rates of 122.5 and a minimum of 54, while you guys got only 92FPS at 19X12. That's a huge difference of frames.
For Crysis, AnandTech managed 40FPS at 19X12, Hardware Canucks managed average of 36FPS and minimum of 21.6FPS at 19X10 with High Detail, 2X AA, and 64 bit while you guys got only 28FPS at 19X12. Now AnandTech doesn't state what quality they used, but it's probably something like high and above right? That we can only guess....
The test systems, such as CPU, RAM, etc have an impact on the GPU performance, but is the performance difference that big? I compared the test systems between you guys and Hardware Canucks, and the systems are basically the same. Same CPU except that theirs is at 3.8Ghz. Mobo are both X48 chipsets so the performance difference caused by the motherboard should be maybe 1 or 2%. They used high frequency DDR2 while you guys used high frequency DDR3. And the OS is Vista Ultimate, with them using 64 bit with SP1. Hard drive is different too, with you guys using a Raptor X while they used a Hitachi Desktar.
Sorry if I'm sounding negative, but it's just that the performance difference is really big.
as a rule every review will vary slightly, with differences in hardware, software, temps, and different actual benchmarks, you'll never get a replicable result, so they are averaged, maybe nate(and the LR crew) averages more results, maybe less, the main point to hardware reviews with performance being the major key, is: how did it do comparatively to the other cards tested, and in most reviews, the 4870X2 is the most powerful single-card solution in the market as of now
.with an exception of maybe one or games, in certain points in the game, but you ALSO have to keep in mind that these aren't exactly the greatest drivers for the 4870X2, so performance will only increase over time
