Here is the first picture of an NVIDIA reference design GeForce GTX 670.
For the most part, its design will resemble that of reference design GTX 680. The card pictured below is said to have had Leadtek branding, which later got removed. GeForce GTX 670 is carved out of 28 nm GK104 silicon by disabling one of the card’s eight SMX units, resulting in a CUDA core count of 1344.
Its clock speeds are lower than those of the GTX 680, with around 950 MHz core base clock, and core boost clock a little over 1 GHz. It features 2 GB of memory across a 256-bit wide GDDR5 memory interface. The latest price speculation puts it at US $399-$429.
