Rumors are flying fast and furious about the new NVidia GPU, the GT300. Michael Feldman of HPCWire taps his inside sources for some information, and writes it up.
According to Valich’s sources, the GT300 will offer up to 512 cores, up from 240 cores in NVIDIA’s current high-end GPU. Since the new chips will be on the 40nm process node, NVIDIA could also crank up the clock. The current Tesla GPUs are running at 1.3-1.4 GHz and deliver about 1 teraflop, single precision, and less than 100 gigaflops, double precision. Valich speculates that a 2 GHz clock could up that to 3 teraflops of single precision performance, and, because of other architectural changes, double precision performance would get an even larger boost.
His article focuses more heavily on the HPC side of the chip (it’s use in CUDA & GPGPU), but it still sounds like it’ll be a pretty powerful gaming/rendering chip.
