Before this already some news confirmed NVIDIA G80 will use 384bit to reveal saves the position funds, but the present top reveals the card all to use the 256bit position width. Although ATi R520/R580 but the interior used 512bit ring-like to reveal saves the main line its only then 4 to reveal saves the channel, the outside reveals saves the position width still was 256bit.
R600 will bring unprecedented true 512bit to reveal saves the position width, if will provide 2500MHz GDDR4 to reveal saves, then the band width will achieve astonishing 160G/s,we knew even if is the eDRAM band width which X-box in 360 inlays also only then 256GB/s,although in the speed eDRAM is quick many, but X-box 360 eDRAM only then 10MB, but R600 provides is actually 1024MB.
The R600 research and development code number will be Pele, will use TSMC 80 nanometer craft manufacture, will support DirectX 10 completely, will estimate in the next year first quarter issue.
