GeForce GTX 660 and GTS 650 To Be Released on September 6th
The latest rumors suggest that we still need to wait for non-Ti version of GeForce GTX 660. Card is allegedly based on the same GPU as GTX 650 Ti – GK106. This means that in six days there will be only one card released – GTX 660 Ti.
While the GeForce GTX 660 and GTS 650 will arrive on September 6th, GeForce GTX 650 should arrive a month later, but detailed date was not yet revealed. In two months NVIDIA will finally finish releasing their whole Kepler lineup. Currently there is a huge gap between GeForce GT 640 and GTX 670, which is to be filled with GTX 660 Ti in few days. But still GTX 660 Ti is priced at comparable price to HD 7950, meaning it’s designed almost for high-end segment.
GeForce GTX 660 Ti (August 16th)
GeForce GTX 660 Ti will be released on August 16th. Card is based on GK104-300-KD-A2 GPU, which holds 1344 CUDA cores and 24 Raster Operating Units. It’s equipped with 2GB of GDDR5 memory operating on 192-bit interface. For more information visit our specification sub-page for this model.
GeForce GTX 660 (September 6th)
According to multiple leaks GeForce GTX 660 will be powered by Kepler GK106-400-A2 GPU, which still a mystery. We assume that the card will feature 960 CUDA cores. But since the architecture of GK106 is a huge unknown, we cannot predict how many TMUs and ROPs it will have. Following yesterday’s leaked PCB design we learn that card will require one 6-pin power connector. Also GeForce GTX 660 has only one SLI connector, meaning it will support 2-way SLI at most. We know that the card will be equipped with at least 1.5GB of memory, but such model was only found in ACER pre-built desktops, so 1.5GB version might be exclusively for OEM’s. Therefore we assume card will hit retail with 2GB of memory capacity.
GeForce GTX 650 (October)
Furthermore we know, that GeForce GTX 650 (previously with Ti branding) will based on another iteration of GK106 GPU — GK106-220-A2 to be exact. Card will likely feature 768 CUDA cores (but it may have 960 as GTX 660). If GeForce GTX 660 will have 2GB of memory, this mode will likely follow this trend. Almost certainly though it will have 192-bit memory interface.
GeForce GTS 650 (September 6th)
The GTS 650 will be powered by GK107 GPU, which is already available with GeForce GT 640 graphics cards. On the contrary to GT 640, this model will feature GDDR5 memory (GT640 has only GDDR3). Card should have slightly higher price, but the performance gain is not expected to shock any one.
TechPowerUP released new verision of GPU-Z (0.6.4), with a support for GTX 660 Ti, GTX 660 and GTX 650.
