Specifications

NVIDIA’s GeForce 7600 GT is based off NVIDIA’s brand new 90-nm G73 graphics core. G73 supports all the latest features found in NVIDIA’s latest high-end GeForce 7900 cards, including shader model 3.0, NVIDIA’s more robust CineFX 4.0 architecture which boasts more powerful pixel and vertex shaders that have been tuned to handle more complex math operations, high dynamic range lighting, PureVideo, SLI, and transparency anti-aliasing, which can be used to improve anti-aliasing image quality.

The 7600 GT and GeForce 6800 GS

In a nutshell the GeForce 7600 GT supports all the key features found in higher-end GeForce boards, only its been designed from the outset to be cheaper for NVIDIA to produce. Since the GeForce 7600 GT’s G73 GPU is derived from G71 rather than G70, a quick and dirty analogy would be that the GeForce 7600 GT is essentially half a GeForce 7900 GT: the GeForce 7600 GT has half the pixel shaders as GeForce 7900 GT (12 versus 24), half the ROPS (8 versus 16), and half the memory interface (128-bit versus 256-bit). Essentially the only portion of the GeForce 7600 GT that isn’t sliced in half are the vertex shaders. NVIDIA equips the GeForce 7600 GT with five vertex units, whereas the GeForce 7900 GT has eight.

NVIDIA has even integrated one dual-link DVI transmitter into the GeForce 7600 GT, while the 7900 family have two dual-link DVI ports.

Looking over the paper specs, NVIDIA’s GeForce 7600 GT is very well equipped to replace the GeForce 6600 GT, boasting faster memory, more pixel and vertex shaders, and higher core clock speed to boot (both the core clock and vertex clock run at 560MHz on the GeForce 7600 GT). G73 consists of 177 million transistors, in comparison GeForce 6600 GT contained 146 million while the X1600 contains 157 million. Enough with the paper specs though, let’s take a look at the actual card!
