GTX 750 Ti is the name and according to ChinaDIY, the card will feature another revision of the GK106 GPU, with 960 cores, 80 TMUs and 32 ROPs. The base clock is 1033MHz and it can hit 1098MHz on boost. However, the memory bus is now 256 bits wide, whereas 192 bits was the norm on old GK 106 products.
It’s got 2GB of GDDR5 clocked at 1502MHz and as a result the bandwidth is 192.3GB/s. The peak bandwidth on the old GTX 660 Ti was 144GB/s, which was upped to 192GB/s on the GTX 760 thanks to the addition of a 256-bit bus, with a very positive effect on overall performance.
There is still no word on price or the possibly launch date, but the GTX 750 Ti should end up on the cheap side – anything over $200 would render it quite pointless.
