Nvidia Tightens Up Midrange Performance With The $300 GeForce 7950GT

Page 2 of 7:

Tech Specs

The GeForce 7950GT should exhibit performance gains over the GeForce 7900GT just from faster clock frequencies - it has all of the same core components as the 7900GT, but is running them 100 MHz faster. The vertex shaders are operating at 570 MHz, and the rest of the core is at 550 MHz. At 700 MHz (1.4 GHz DDR), the memory is 40 MHz faster than the GeForce 7900GT. Below is a chart that lays out all of the 7000 series cards and their Nvidia reference design specifications.
