Details of AMD's next generation Radeon hit the web
Newly created site Level 505 has leaked benchmarks and specifications of AMD’s upcoming ATI R600 graphics processor. The upcoming graphics processor is expected to launch in January 2007 with an expected revision arriving in March 2007. These early specifications and launch dates line up with what DailyTech has already published and are present on ATI internal roadmaps as of workweek 49.
Preliminary specifications of the ATI R600 are as follows:
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.
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.
Other notable hardware features include hardware support for quad DVI outputs, but utilizing all four outputs are limited to FireGL workstation edition cards.
There’s also integrated support for multi-GPU clustering technologies such as CrossFire too. The implementation on the ATI R600 allows any amount ofATI R600 GPUs to operate together in multiples of two. Expect multi-GPU configurations with greater than two GPUs to only be available for the workstation markets though.
The published results are very promising with AMD’s ATI R600 beating out NVIDIA’s GeForce 8800 GTX in most benchmarks. The performance delta varies from 8% up to 42% depending on the game benchmark.
When DailyTech contacted the site owner to get verification of the benchmarks, the owner replied that the benchmark screenshots could not be published due to origin-specific markers that would trace the card back to its source -- the author mentioned the card is part of the Microsoft Vista driver certification program.
If Level505's comments seem a little too pro-ATI, don't be too surprised. When asked if the site was affiliated in any way to ATI or AMD, the owner replied to DailyTech with the statement that "two staff members of ours are directly affiliated with AMD's business [development] division."
I am suspicion of such performance increases from R600. This is because the 8800GTX bottlenecks so many systems. How can they claim a 40+% increase in performance when 8800GTX's in SLI bottleneck a overclock QX6700.
