NVIDIA Plans Two New SKUs Based on GK106
A little later this month, NVIDIA plans to launch the GeForce GTX 660, its first desktop GPU based on the 28 nm GK106 silicon. The GTX 660 carries NVIDIA's ASIC codename GK106-400. An internal document detailing other SKUs based on the GK106 in the works, was leaked to the web. According to a 3DCenter.org report, the two ASIC codenames GK106-250 and GK106-200 described in the document could be new SKUs.
The GK106-250, carrying a working title GeForce GTX 655, could have one of the five SMX units of the GK106 disabled, resulting in a CUDA core count of 768. According to the document, it features a 192-bit wide GDDR5 memory interface, holding 2 GB of memory, much like the GTX 660. The GK106-200, on the other hand, with a working title GeForce GTX 650 Ti, could feature just three of the five SMX units on the GK106 silicon, making up 576 CUDA cores. According to the document, it features 2 GB of GDDR5 memory across a 128-bit wide memory interface, much like the GK107-based GTX 650. The two SKUs could help NVIDIA seal gaps in its mainstream desktop GPU lineup.
