NVIDIA GeForce 7800 GTX 512 ReviewPosted on 2005-11-14 20:15:46 by LSDsmurf
This new 512MB version of the GeForce 7800 GTX, you see, doesn't run at the 430MHz GPU and 1.2GHz memory clocks that the standard version does. Oh, no. This card is intended to compete with—nay, embarrass—ATI's ultra-high-end Radeon X1800 XT, the recently crowned king of single-card graphics performance. NVIDIA's not calling it an Ultra, but they might as well be, with clock speeds of 550MHz for the GPU and 1.7GHz for the memory. That, my friend, is fast. We're talking about 13.2 gigatexels per second of fill rate and over 54GB per second of memory bandwidth..
