The G92 is NVIDIA's next-generation GPU and according to rumours this chip will be available in the fourth quarter of this year.
In a separate answer to an analyst's question, he also noted that they have no intention from diverging from the cycle they have adopted with the G80, which is to have the high-end part ready at the end of the year and release the lower-end derivatives in the spring.Beyond3D also reports that NVIDIA isn't really impressed with ATI's R600 and believes this GPU won't really have an impact on their G80 sales. However, NVIDIA believes the ATI RV610 and RV630 are much more competitive chips that will likely gain traction in the marketplace.
Assuming that NVIDIA manages to hit these aggressive release schedules, it implies that the chip will compete with any potential R6xx refresh at the beginning of its lifetime, but also eventually with R700 as it seems unlikely NVIDIA will refresh again before the second half of 2008, unless they go for an optical shrink from 65nm to 55nm. It also remains to be seen how aggressive ATI will be on the process front this time around.
There also were a number of other highlights during the conference, including a major emphasis on GPGPU (aka 'GPU Computing') and a short mention of Intel's upcoming GPU efforts through their Larrabee project. Micahel Hara seemed far from certain about Intel's exact strategy there, although he did mention that it was possible Intel was more interested in the GPGPU market than the gaming one. This is something we have already said in the past.
