We heard that G80 will be in time for launch in June during Computex and the process technology is likely to be 80nm at TSMC. In the recent statement, NVIDIA has said that they will be backing the 80nm "half-node" process by TSMC where it allows reduction of die size by 19%. We have previously mentioned that G80 is likely to take on the Unified Shader approach and supports Shader Model 4.0. G80 is likely to be paired up with the Samsung GDDR4 memories reaching a speed of 2.5Gbps. As for ATi, the next generation R600 is slated for launch end of this year according to the roadmap we have seen and the process technology is 65nm. It seems that the leaked specs of the R600 that surfaced in June last year is pretty likely.
According to Xpentor, NVIDIA G80 will make ATI stumble on April. Quad SLI itself can be implemented on a single card with two chips solution because it will carry the first dual core GPU ever with the support of DirectX10 and Shader Model 4.0. The development of G80 is also mentioned as being running very intensive since NVIDIA\'s acquisition over ULi. As for the upcoming G71, there will be 32pipes, increase in ROPs and a little speed bump over the core clock.
