Message Text: NVIDIA has released five new OEM graphics cards for the desktop market, based on both 28nm Kepler and 40nm Fermi GPUs.

The GT 645 is based on Fermi GF114 core and has 288 CUDA cores paired with a 192-bit memory bus and a core clock running at 776MHz.

The GT 640 comes in three vesions: A full GK107 (384 cores) GT640 (GDDR5 memory 950MHz clock), a GF116 (144 cores) GT 640 version with DDR3 memory and a 720MHz clock speed, and a GT 640 that’s a full GK107 (384 cores) with DDR3 memory and a 797Mhz clock speed.

The final card is the GK107-based GT 630. This is also a full GK107 (384 cores), paired with DDR3 memory and a clockspeed of 875MHz.
