Here is another review testing at extremely high resolutions:
Digit-Life - May 24, 2007
Drivers: ATI 8.37
NVIDIA 158.18/158.19.
Far Cry Research @ 2560x1600 4AA/16AF
8800GTX = 83
HD 2900XT OC 850/2000 = 55.4
HD 2900XT = 47.8
8800GTS 640 = 48.4
8800GTS 320 = 46.7
*Note at 1600x1200 all the cards provide > 60 FPS.
Far Cry Research HDR @ 2560x1600 4AA/16AF
8800GTX = 55
HD 2900XT OC = 47.2
HD 2900XT = 41.7
8800GTS 640 = 36.4
8800GTS 320 = 28.3
*Note at 1600x1200 all the cards provide > 60 FPS.
FEAR @ 2560x1600 4AA/16AF
8800GTX = 45
HD 2900XT OC = 45
HD 2900XT = 37
8800GTS 640 = 32
8800GTS 320 = 26
*wouldn't call this acceptable performance on any card. Note at 1600x1200 all the cards provide > 60 FPS.
Splinter Cell: Chaos Theory @ 2560x1600 4AA/16AF
8800GTX = 52.3
HD 2900XT OC = 57.4
HD 2900XT = 47.1
8800GTS 640 = 31.2
8800GTS 320 = 29
*Note at 1600x1200 all the cards provide > 60 FPS.
Splinter Cell: Chaos Theory HDR @ 2560x1600 4AA/16AF
8800GTX = 45.1
HD 2900XT OC = 51.5
HD 2900XT = 42.8
8800GTS 640 = 34.0 (odd that this is greater than above without HDR)
8800GTS 320 = 27.7
*Note 8800GTS 640 and 320 cannot provide 60FPS at 1600x1200. However, for this game even high 50s is fast enough.
Call of Juarez @ 1024x768 4AA/16AF (running at higher resolutions kills all the cards other than GTX):
8800GTX = 64
HD 2900XT OC = 42.5
HD 2900XT = 38
8800GTS 640 = 50
8800GTS 320 = 49.6
*Note potential ATI driver problems and room for improvement as HD 2900XT can barely outperform X1950XTX.
Company of Heroes @ 2560x1600 4AA/16AF
8800GTX = 34.7
HD 2900XT OC = 51
HD 2900XT = 45
8800GTS 640 = 23.9
8800GTS 320 = 20.4
*Note ATI clearly dominates this benchmark as even X1950XTX outperforms 8800GTX at this setting.
Serious Sam II @ 2560x1600 4AA/16AF
8800GTX = 73.8
HD 2900XT OC = 72.4
HD 2900XT = 62
8800GTS 640 = 49.5
8800GTS 320 = 33.8
*Note at 1600x1200 all the cards provide > 60 FPS.
Serious Sam II HDR @ 2560x1600 4AA/16AF
8800GTX = 54.6
HD 2900XT OC = 60
HD 2900XT = 51.4
8800GTS 640 = 37.8
8800GTS 320 = 13.5
*Note at 1600x1200 all the cards provide > 60 FPS.
Prey @ 2560x1600 4AA/16AF
8800GTX = 48.9
HD 2900XT OC = 53.1
HD 2900XT = 45
8800GTS 640 = 34
8800GTS 320 = 33.3
*Note at 1600x1200 all the cards provide > 60 FPS.
Conclusions:
- For resolutions at or below 1600x1200 4AA/16AF, 8800GTS 320 provides the best value as it can sustain 60FPS in most of the games tested
- At the current time from the games tested HD 2900XT has a far superior ability to handle HDR than 8800GTS series outperforming NV in all HDR tests including: 1) Far Cry; 2) Splinter Cell: Chaos Theory; 3) Serious Sam II
- At stock speeds 8800GTX is the fastest card. Overclocked HD 2900XT becomes a serious contender and often outperforms 8800GTX
- Potential for future performance improvements as HD 2900XT sometimes barely outperforms previous generation X1950XTX
- Any conclusions related to DX10 implementation and efficiency in true DX10 games unknown relative to GeForce 8 due to lack of any true DX10 games
