Californian fabless GPU and ARM CPU designer is apparently dead-set on launching a GeForce GTX 660 Ti video card that will be able to use the GTX 670 PCB. This means that the Ti suffix will come together with a 256-Bit memory interface.
The lesser GeForce GTX 660
version will come with the same GK104
GPU, but it will feature a 25% narrower memory
BUS that will also allow the card to fit into a more modest 130-watt TDP.
There are various sources
that talk about a GK106 GPU that will likely power the GTX 660
in the future once it tapes out from TSMC
The full specifications reportedly
show a well-known GK104
Kepler GPU that will have only 1152 CUDA cores active clocked at a default 980 MHz frequency, with a 1033 MHz Boost option and the same 6008 MHz frequency for the 1.5 GB of GDDR5 video memory.
The GTX 660 Ti model might come with a 1133 MHz Boost option, but we find that very unlikely.
