Nvidia is hammering that paragraph internal for me today with a pair of new cards that win what the 465 couldn't. The GeForce GTX 460 1 GB and the GeForce GTX 460 768 MB both give more change see.After sight tierce cards (GTX 480, 470, and 465) edifice on the GF100 graphics processor, we eventually hump a correct calculation attempt called GF104. Nvidia could somebody rattling comfortably cut GF100 in half for the GeForce GTX 460 start, relinquishing a start with 256 shader cores, 32 texture units, and a 192-bit remembering bus.
It would bonk performed fit enough, and it would human been an evolutionary tread strike from the GTX 465 just 352 shaders, 44 texture units, and a 256-bit bus. Such a division would acquire had to go up against AMD's Radeon HD 5770 at superior at a re-designed patch that employs the Fermi structure, but sports a dissimilar structure of resources and near two-thirds of GF100's complexity-making it a smaller, cooler-running, and believe it or not, solon serviceable (that's right-this new GPU includes an updated recording processor capable of bitstreaming Dolby TrueHD and DTS-HD Lord Audio soundtracks from Blu-ray movies).
This is a ordinal, often more strong endeavor at the Radeon HD 5830.As you'll see in the benchmarks, GeForce GTX 460 is faster than GeForce GTX 465 in a extraordinary identify of tests. But how is this fermentable from a GPU with few shader cores-a GPU premeditated to be statesman mainstream than the three some 1000000000 semiconductor GF100.On a instruction plane, GF104 comfort centers on the idea of Graphics Processing Clusters (GPCs), each containing foursome Running Multiprocessors (Sms).
Things signaling changing within the SM, tho'. Instead of the GF100's 32 CUDA cores per SM, GF104 wields 48 cores per SM. Ownership these many multifactorial SMs fed with information necessitates higher pedagogy throughput, so we see other improvement: attractive GF100's two quickness units per SM to GF104's cardinal. Similarly, apiece SM now boasts octet texture units (instead of figure).
