Nvidia GT200 GPU fp performance @ 1 to 1.33 TFLOP
192xGT200 + 1068xBloomfield: 295 TFlops Supercomputer
Wednesday 23rd April 2008, 02:00:00 PM, written by Arun French website PC INpact broke the news of an upcoming GPU-accelerated supercomputer, ordered by France's CEA for delivery in early 2009 from Bull. The cluster's performance confirms that GT200 will be rated at 1TFlop and that Nehalem/Bloomfield will clock up to at least 3GHz. PC INpact claims that the overall machine will sport peak performance of 295 TFlops, with 103 TFlops coming from the CPU and 192TFlops coming from the GPUs. Le Monde further confirms the performance target and indicates delivery will take place in early 2009. This would make it one of the world's first (if not the first) large-scale GPU- accelerated supercomputer. Sadly, PC INpact got the specifics wrong. There won't be a 8-core Nehalem in that timeframe, and neither could there be a 2TFlops single- chip GPU, especially given the qualification times in this market. Just like Conroe, Nehalem/Bloomfield will sport a 128-bit ADD and a 128-bit MUL per core; at 3GHz, that means 24 GFlops per core. Multiply that by the four cores per chip, then by 1068, and you get to ~103TFlops. As for the GPUs, obviously the 1U Tesla module sports 4 GPUs, not 2. So assuming this supercomputer is indeed based on GT200 and the per- module config is similar, that gives us 1TFlop per chip/board.[/b] Alternatively, if the TDP was substantially higher than G80's (which seems unlikely given the level of binning possible in that market), it might be possible that the module only sports 3 GPUs; that would result in 1.33 TFlops per GPU. Once again, that is not the most likely scenario. So, that gets us right back to where we were back in... May 2007, with Michael Hara's claim in an investor conference that their next- generation would be 'close to 1 TFlop'. Of course, we were all assuming that was referring to G92, and that obviously didn't turn out to be the case. We also assumed G92 would be the first chip supporting FP64; now, it has become clear however that's GT200 - which is also what makes the chip more attractive in such supercomputer deals. In practice, this doesn't represent a lot of revenue for NVIDIA; it's very likely less than one million dollars for a company which is consistently delivering sales of more than one billion dollars per quarter lately. However, it does highlight Tesla's momentum in the GPGPU market. How soon, if ever, will that represent a substantial part of NVIDIA's profits? Nobody knows. http://www.beyond3d.com/content/news/632 (almost a year ago.....) 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. http://www.beyond3d.com/content/news/230 |

Nvidia GT200 GPU fp performance @ 1 to 1.33 TFLOP
Well yes that's a bit impressive..BUT I bet it won't run GOTHIC 3 jerk free.
