crossfire Crosfire is ATI's version of SLI... instead of having an internal cable (bridge) you need to connect, they have an external cable... a crosfire cable... No settings needed, its mostly "plug 'n pray"
they just tried to make it more hassle-free than the SLI, where you have to, connect the bridge, enable SLI in windows, then restart to make it all work.... (but then again, how often will you change the SLI settings??? is it really that much more effort to do it once and leave it? )
I just tested the difference between 2 cards.... fairly similar cards...
The first a Leadtek nVidia A6800 LE TDH 128 bit, 256 MB card (a GeForce 6800 card)
The second a Leadtek nVidia A6800 A400 TDH 256 bit, 256 MB Card (also a GeForce 6800 card)
now not to bore anyone with detailed specs of a benchmark program... i decided to rather use something simpler, and more to the point of basic evidence Larian's very own "Config tool" that tests the Frames per second...
The first card got on 1600 x 1200 FSAA 0, Fog ON a FSP of 65 - 68 (i ran a few tests to make sure)
The second card got on the same settings 93 - 98 FPS (i also ran a few tests to make sure)
now the differrence between the 2 cards:
card 2 is 256 bit (double the processing bandwidth -speed that data can get gathered and sent), faster ramdac (450 MHZ), UMFB memory (runs at the same speed as the GPU, instead of having its own speed that can be slower than the GPU)...
card 1 is 128 bit (like MOST cards still) normal ramdac 350 MHZ, DDR 3 memory (400 MHZ - in this case faster than the GPU, so no bottleneck)
I cant even identify the 2 cards from each other... they look EXACTLY the same.
