[H]ard|OCP is back with a performance review of the ATI Radeon HD 5870 Eyefinity6 graphics card. As we described earlier, this card is no different than the regular AMD Radeon HD 5870 with the exception of its having 6 mini-DisplayPorts, and 2 GB of memory. Does having 2 GB of memory help the performance? What does [H]ard|OCP think of the new card?
It boils down to this, when the video cards are not so GPU limited, in the case of multi-GPU CrossFireX, we are able to utilize the frame buffer more. We can crank up more settings, enable higher AA settings if the frame buffer space is there for it. With single-GPU video cards running a high resolution like 5760×1200 we are pushing the limits of the GPUs and not really taxing the frame buffer as much. So, it comes down to the fact that CrossFireX is going to benefit more from a 2GB frame buffer per GPU than single-GPU video cards are at high Eyefinity resolutions.
