NVIDIA release desktop graphics cards on 28nm GK107

NVIDIA released its first desktop graphics cards based on its 28 nm GK107 silicon, in as many as three models, the GeForce GT 630, GT 640, GT 640 (second variant).
Apart from these, NVIDIA appears to have launched two more models, one labeled GT 640, and another GT 645, which are based on previous generation GF116 and GF114, respectively. These new SKUs are available only to OEM partners, who will implement them in their new desktop PC designs.
Of the five new SKUs, the GT 630 and GT 640 (28 nm) are most interesting, as they are based on the GK107 silicon, with as many as 384 CUDA cores, and TDP as low as 50W. The GT 630 is a single-slot, low-profile graphics card with 384 CUDA cores, and a 128-bit wide GDDR5 memory interface, 875 MHz GPU clock speed, and 891 MHz memory clock speed. The GT 640 (28 nm) features different clock speeds.
The specifications may seem confusing to the end user, but then they really don’t concern people who buy retail-channel graphics cards. NVIDIA and AMD design OEM-specific SKUs completely à la carte, to OEM partners’ requirements.
