UPDATE: Ok I had to rewrite this post, because NVIDIA posted wrong specs.
NVIDIA has quietly added a new graphics cards to their line-up. The non-Ti version of GTX 660 Ti has appeared on NVIDIA pages with all the specifications we could expect (well almost).
First of all, the non-Ti variant will has the same reference design as GTX 670 and GTX 660 Ti. Secondly it looks like a GK104 based GPU, but this cannot be verified at the moment. The GPU they used has 1152 CUDA Cores, which is 192 less than GTX 660 Ti and GTX 670. So the GPU is missing two SMXs. Also what was earlier said in numerous leaks, card features 1.5 GB or 3GB memory (there will be two variants). But it also utilizes 192-bit memory interface. The memory bandwidth was measured at 134 GB/s — the memory is down-clocked to 5.8 GHz.
The base clock is 823 MHz, while the boost clock is set to 888 MHz.
Card consumes up to 130W (TDP), which is lower than GTX 660 Ti (150W). The non-Ti variant of GTX 660 requires one 6-pin power connectors. In comparison to other high-end Kepler graphics cards, this one will only support 2-way SLI configuration.
The GeForce GTX 660 Ti 1.5/3GB is available with ACER Predator and Dell Alienware gaming desktops. NVIDIA has not yet added the card to their performance chart so it’s a mystery how it performs.
Official launch for retail market should take place in September.
