Details of AMD's next generation Radeon hit the web
has leaked benchmarks and specifications of AMD’s upcoming ATI
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
has already published and are present on ATI internal roadmaps as of workweek 49.
Preliminary specifications from
of the ATI
are as follows:
64 4-Way SIMD Unified Shaders, 128 Shader Operations/Cycle
32 TMUs, 16 ROPs
512 bit Memory Controller, full 32 bit per chip connection
GDDR3 at 900 MHz clock speed (January)
GDDR4 at 1.1 GHz clock speed (March, revised edition)
Total bandwidth 115 GB/s on GDDR3
Total bandwidth 140 GB/s on GDDR4
Consumer memory support 1024 MB
DX10 full compatibility with draft DX10.1 vendor-specific cap removal (unified programming)
32FP [sic] internal processing
Hardware support for GPU clustering (any x^2 [sic] number, not limited to Dual or Quad-GPU)
Hardware DVI-HDCP support (High Definition Copy Protocol)
Hardware Quad-DVI output support (Limited to workstation editions)
230W TDP PCI-SIG compliant
This time around it appears AMD is going for a different approach by equipping the ATI
with less unified shaders than NVIDIA’s recently launched GeForce 8800 GTX. However, the unified shaders found on the ATI
can complete more shader operations per clock cycle.
ATI's interal guidance states the R600 will have 320 stream processors at launch; 64 4-way unified shaders only accounts for 256 of these stream processors.
claims AMD is expected to equip the ATI
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
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
allows any amount of
GPUs to operate together in powers 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
beating out NVIDIA’s GeForce 8800 GTX in most benchmarks. The performance delta varies from 8% up to 42% depending on the game benchmark.
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.
'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
with the statement that "two staff members of ours are directly affiliated with AMD's business [development] division."

small corection, the average home outlet is 15amp, at least in the USA thats the code. while some outlets are 20amp. those are usualy deticated for apliance use, such as window a/c units ect...
