ATI Radeon HD 5870 Eyefinity 6 pushes pixels and performance

High resolution gaming has always been an issue due to the relatively lack-luster performance of graphics chips in the past but now that they’ve finally caught up on that aspect there are other limitations, mainly the amount of video memory that’s available.

HardOCP has taken a look at how well the ATI Radeon HD 5870 Eyefinity 6 handles multi-monitor, high-res gaming even in CrossFireX configuration:

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.

If you’re into the high-end multi-monitor gaming extravaganza well it’s clear which setup you’re going to go after.
