The NVIDIA GeForce 7600 GS is a single slot card that features a 400MHz core clock speed with a GDDR2 memory clock speed of 400MHz (800MHz double data rate). The 7600 GS features 5 Vertex shading units with a total of 12 pixel shader pipelines. This is the same number of shading units and pipelines found on the GeForce 7600 GT, so the only difference on the card is the clock speeds and the memory type used. Thanks to the lower clock speeds NVIDIA has been able to get the peak power consumption down to 32 Watts from the 67 Watts found on the 7600 GT.
