nVidia G80 GPU is expected to be released in H2 (possibly as early as June). G80 expected to be released on TSMC's new 80nm process and will likely be the first DirectX 10 / Shader Model 4 compliant GPU on the market, indicating a total core redesign over G70/G71 and the implementation of a Unified Shader Model which processes vertices and pixels through the same dual purpose pipelines. In addition to SM4 support, improved SM3 performance and enhancements to the texture filtering engine are also expected. G80 clock speeds are expected to be around 700Mhz and the core will interface to GDDR4 memory.
nVidia G83 GPU is expected to be released in H2. G83 is a mid range GPU and the successor to the GeForce 7600, featuring the enhancements found in the G80 core.

G83 verkar RIKTIGT lockande, min mun dreglar när jag läser detta, detta medelklass kortet kommer ju klå x1900 (lite överdrivet jag vet, men man kan ju drömma)
GDDR 4 som jag är mest intresserad av kommer ju att vara grymt mycket snabbare än GDDR 3, sen DirektX 10 och shader model 4 är inte illa pinkat det heller, hoppas bara korten kommer att ligga på 2000:-

Fortsättning, en annan källa
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.
