Radeon: Performance
built 448 days ago
The 256MB variant of the Radeon 9800 Pro is virtually identical to the 128MB model. The only difference is the 256MB Radeon 9800 Pro uses DDR II memory which has a higher latency compared to the old DDR memory. Therefore, a slight memory clock speed bump was implemented to eliminate any loss of performance due to the increased DDR II latency.

This release for all Radeon family products updates the AMD Display Driver to version 8.391. This particular software suite updates both the AMD Display Driver, and the Catalyst Control Center. This unified driver has been further enhanced to provide the highest level of power, performance, and reliability.

At a resolution of 1,600-by-1,200 with 4X full-scene anti-aliasing and 8X anisotropic filtering enabled, the Radeon 9700 Pro sustained playable frame rates while the WinFast Ultra often couldn't. Take the Comanche 4 demo (not included in the table), for example: At 1,600-by-1,200 without anti-aliasing, the Radeon 9700 Pro ran at 33 fps—tied with the WinFast Ultra. But adding anti-aliasing reduced the WinFast Ultra's performance by more than 50 percent, to 16 fps. The Radeon 9700 Pro took a smaller hit, slowing only to 27 fps.

Only certain situations using high FSAA settings gave the 256MB Radeon 9800 Pro a slight edge over its 128MB brother. Even then, the slight improvement in performance didn't make the additional USD 100 worth considering. Or is that REALLY true?
