Nvidia preparing Geforce GTX 455, GTX 460 and GTX 49
 

Following the aftermatch of Computex, rumours about Nvidia's future cards are starting to hit the internet. First up would be the 460 card, followed by 455 and 490. The GTX 460 appears to be the odd 336 SP product, 768MB mated to a 192-bit. The 455 card - which may end up being labeled GTS or GTX - is based on GF106, and will be priced under $200 to take on the HD 5700 series. Finally, GTX 490 will be a dual-GPU product, consisting of two GF104/GTX460 cores.

While previous rumours suggested GF104 will be 240/256 SP and GF106 will be 128-160 SP, the current rumours suggest GF104 will be a far more powerful chip. The reason for the odd SP count of 336 is that the 460 could be that it is based on GF104, which realters the nature of each SM. The GF104 SM, then, contains either 16 or 48 SP - and perhaps, with some disabled for the 460 part. The full GF104 might then be a 384 SP product. The GTX 465 will almost certainly be EOLed not much following the release of the 460.
