NVIDIA confirms Next-Gen close to 1TFlop in 4Q07
Wednesday 23rd May 2007, 12:12:00 PM, written by Arun
In recent analyst conferences that were publicly webcast on NVIDIA's website, Michael Hara (VP of Investor Relations) has claimed that their next-generation chip, also known as G92 in the rumour mill, will deliver close to one teraflop of performance. 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.
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.
And finally, he mentioned that although he does not believe R600 will have any impact on their G80 sales, RV610 and RV630 are much more competitive parts that are likely to gain traction in the marketplace. He argued that he was not convinced 65nm gave AMD a real advantage in terms of costs because of the yield curve, and seemed confident that their own 65nm mainstream parts will be superior. We can't help but wonder how much that matters when you release them 9 months later, though? It will also be interesting to see who's first to 55nm, and how good of a half-node it will be.

If quad X always goes to TMUx, then a predication mask that always masks (say) quad 2, will leave TMU2 without any work to do.
I'm not sure how a local TMU uses the ring at all -- local ALUs talk to local TMUs, I wouldn't expect that to be over the ring.
As it is, ALUs are always talking to remote TMUs (how remote depends on which quad). Have I misunderstood something? [that's a stupid question ;)] What have I misunderstood?
