2.0 GHz memory frequencies? No problem.

Anh beat me to R600 benchmarks by a few mere hours -- when you snooze, you lose at DailyTech. Needless to say, I feel somewhat compelled to add my benchmarks to the mix as well. 

The system I'm using is an Intel Core 2 Extreme QX6800, ASUS P5N32SLI-E with 2x2GB DDR2-800.  My tests this morning used the Catalyst 8.361 RC4 driver.  The card used was a Radeon HD 2900 XT 512MB.

Core Clock
Memory Clock
745 MHz
800 MHz
800 MHz
900 MHz
845 MHz
950 MHz
845 MHz
995 MHz

Like Anh, I was able to get pretty close to a 2.0GHz memory clock while still keeping the system stable.  For reference, my GeForce 8800 GTX (core clock at 650 MHz, memory at 2.0 GHz) scores 14128 (1280x1024) and 11867 (1600x1200) on the same system with ForceWare 158.19. 

I'm currently benchmarking the Radeon HD 2900 XTX, though I'll revist the XT if anyone has any particular requests.

Wake up.

The shaders run at almost double speed of main clock in G80 generation so approximately 1.35 GHz.
This is what the G80 gives its speed.

All components inside R6xx runs on main clock.

Conclusion: one cannot compare those two generations of cards on the sole main clock frequency.

Wake up.
