NVIDIA "GTX 790" Will Have 10GB GDDR5?
 

According to the crew at WCCF Tech, NVIDIA has plans to announce a GTX 790 that will have 10GB of GDDR5 640bit bandwidth, 4992 CUDA cores and will be release in February. It appears that the "GTX 790" will not be a Dual 780 Ti, a Dual Titan or even a Dual GTX 780. It is rather something inbetween these three. A 780 has 2304 Cuda Cores, a Ti 2880 and a Titan 2688. The Nvidia Geforce GTX 790 will have: Cuda Cores: 2496 (x2) Memory: 5Gb GDDR5 (x2) Mem Bus: 320 Bit (x2) Core: GK110 (x2)...
