Fudzilla claims that the Radeon HD 2900 manages an impressive 102.4GB/s memory throughput. The card uses a 512 bit memory interface and 1600 MHz GDDR3 memory. The core was clocked at 800 MHz. For comparison, NVIDIA's G80 with its odd 384 bit memory controller scores 86.4 GB/s.
The new HD 2900 XTX with GDDR 4 memory clocked at 2200 MHz, as originally planned, can theoretically have 140.8 GB/s. Both cards have twice or close to twice more memory bandwidth from ATI's Radeon X1950XTX card. This card was limited to a now modest 64GB/s.
Editors note: The NDA on the R600 makes it impossible for anyone to release accurate benchmarks of the R600. In fact, the NDA is so strict, we'll be lucky if the leaked R600 pictures have any accuracy. The theoretical memory bandwidth was attained by simple math: 512bit * 1600MHz / 8bit = 102.4GB/s.
