Getting back to NVIDIA - as expected, the GK104 chips which did not "pass the mustard" will be recycled and named GeForce GTX 670 and GTX 670 Ti. According to German publication 3DCenter.org, GK104 will take the GF100 (GeForce GTX 465/470/480) route: GK104 on the new cards will have one SMX less (7 in total), bringing a total of 1344 cores (should we still call them CUDA cores given the amount of GPGPU performance castration performed with Kepler?).
The remainder of the chip will remain the same, and we're looking at the following specs:
1344 Cores
4 Graphics Processing Clusters (GPC)
7 SMX Clusters (192 units per Cluster)
112 Texture Units (TU)
32 Raster Units (ROP)
256-bit Memory Controller
2 GB GDDR5 Memory
~900 MHz GPU Clock
~1 GHz QDR Memory Clock (5 effective GHz)
~160 GB/s video memory bandwidth
As you can see, theoretical performance of the card targets the previous generation GeForce GTX 580 and direct competitor AMD Radeon HD 7950 3GB. Coupled with NVIDIA wanting to increase the price pressure to the red team. the new cards undercut the Radeon HD 7950 by $50-100, pitching the product around $349-399.
