This time around it appears AMD is going for a different approach by equipping the ATI R600 with less unified shaders than NVIDIA’s recently launched GeForce 8800 GTX. However, the unified shaders found on the ATI R600 can complete more shader operations per clock cycle.
Level505 claims AMD is expected to equip the ATI R600 with GDDR3 and GDDR4 memory with the GDDR3 endowed model launching in January. Memory clocks have been set at 900 MHz for GDDR3 models and 1.1 GHz for GDDR4 models. As recent as two weeks ago, ATI roadmaps had said this GDDR3 launch was canceled. These same roadmaps claim the production date for R600 is February 2007, which would be after a January 22nd launch.
Memory bandwidth of the ATI R600 is significantly higher than NVIDIA’s GeForce 8800-series. Total memory bandwidth varies from 115GB/s on GDDR3 equipped models to 140GB/s on GDDR4 equipped models.
