GeForce 7800GTX vs. 7900GTX


While we have just covered the physical side of the card itself, we will have a quick look at what the 7900GTX offers over the previous generation.


As we have mentioned already, we have two Dual Link DVI-I ports to power two 30" Apple or Dell LCDs. It is important to remember that Dual Link isn't needed to power 30"+ LCDs but just the two specific models available from Dell and Apple at the moment, which punch out a massive 2560 x 1600 resolution.


Moving more onto the core, this is nVidia's first 90nm chip and what took ATI months and a huge amount of delays nVidia seemed to do without breaking too much of a sweat. The move to 90nm gives us higher clock speeds and cooler temperatures.


24 pixel pipelines are included on the 7900GTX (like the 7800GTX) but thanks to the increased core speed, performance should be increased without any problems at all.


Speaking of increased speeds, the standard clocks on the core is 650MHz which is a HUGE jump from the 430MHz found on the 7800GTX and memory has been bumped from 1200MHz to a massive 1600MHz thanks to the 1.1ns memory being used.


Now with stock speeds being all good and well, it's a bit boring. BFG Tech has given a small bump at both ends with a core of 670MHz and memory speed of 1640MHz.


With all that out the way let's have a look at how we go in our benchmarking results.
