RealWorldTechPerhaps the most significant demonstration of Nvidia's commitment to compute is the fact that a great deal of the new features are not particularly beneficial for graphics. Double precision is not terribly important, and while cleaning up the programming model is attractive, it's hardly required. The real question is whether Nvidia has strayed too far from the path of graphics, which again depends on observing and benchmarking real products throughout AMD's, Nvidia's and Intel's line up; but it seems like the risk is there, particularly with AMD's graphics focus.
These are all important questions to ponder in the coming weeks, and really feed into the ultimate technical question - the fate of CPU and GPU convergence. Will the GPU be sidelined for just graphics, or will it be like the floating point coprocessor, an essential element of any system? Will it get integrated on-die, and to what extent will the discrete market remain? These are all hard to predict, but it's clear that Nvidia is doubling down on the GPU as an integral element of the PC ecosystem for graphics and compute and time will tell the rest.

TESLA):
6-pin + 8-pin -> TDP ~300W

Produkty založené na jádře "Fermi" by se měli dostat na retail trhy v Q1 2010...First thing worth pointing out is that Nvidia sees clear potential in High Performance Computing and GPU Stream Computing - perhaps even more than gaming - and believe there is multi-billion dollar potential in the HPC industry, which is currently dominated by much more expensive and less powerful CPUs...
...Products based on the Fermi architecture will only be available on retail stores in Q1 2010 - which is a rather long time away. This length delay and yields/costs could be two major problems for Nvidia. While there is no doubt Fermi/GF100 is shaping up to be a strong architecture/GPU, it will be costlier to produce than Cypress. We have already heard horror stories about the 40nm yields, which if true, is something Nvidia will surely fix before the product hits retail. However, this does take time, and Nvidia's next-gen is thus 3-6 months away.By then, AMD will have an entire range of next-gen products, most of them matured, and would perhaps be well on their way to die shrinks, especially for Cypress, which would might end up being half a year old at the time...
