Here it is, a full specification of non-Ti variant of GeForce GTX 660.
It has been rumored for some time, now we have a confirmation. A non-Ti model will feature 1536 MB of GDDR5 memory with 192-bit memory interface. GeForce GTX 660 has 1152 CUDA cores and a memory bandwith of 144.19 GB/s. Card will have 24 raster operating units. The only part that is not yet revealed is the actual GPU (likely GK106), but when we look at the transistors count, it looks like a GK104. Card is clocked at 980/1033/1502 MHz for base, boost and memory respectively.
The GeForce GTX 660 will have a performance comparable to Radeon HD 7870, but the leaks suggest that in overall performance it will be slower. On the other hand a faster variant GTX 660 Ti will likely have 256-bit memory interface and 8% worse performance than GTX 670.
UPDATE:
Also a GPU-Z screenshot of the GTX 660 Ti model leaks out.
