ATI R600 and NVIDIA G80 details

NVIDIA is planning to launch their G80 GPU by June during Computex, VR-Zone reports. This chip will use TSMC's 80nm half-node process which allows a reduction of die size by 19 percent.

The G80 (maybe the GeForce 8800?) will likely feature a Unified Shader approach and support for Shader Model 4.0. The memory will likely be 2.5Gbps GDDR4 memory chips from Samsung.

ATI has just unveiled their R580 and by the end of this year we can expect their R600 which will be a 65nm GPU.

Here are some rumoured ATI R600 specifications:

65nm

64 Shader pipelines (Vec4+Scalar)

32 TMU's

32 ROPs

128 Shader Operations per Cycle

800MHz Core
