Review: Eyefinity 6 and 4GB memory
XFX HD 5970 4GB Black Edition graphics card is a limited quantity graphics card that comes at a pretty penny but in turn offers equally pretty performance levels. This naturally means that the card is not quite aimed at the general masses, and this kind of performance is surely not for the faint of heart. We know that Radeon HD 5970 is currently the fastest graphics card around, but XFX pushed the bar even further with its Black Edition card. So, for the price of US$1000/€1000, you’ll get XFX’s HD 5970 4GB Black Edition cards with six video outs, meaning Eyefinity 6.
The reference HD 5970 runs at 725MHz and the memory at 1000 (4000MHz effectively). Many expected the reference dual GPU HD 5970 to end up running at single-GPU HD 5870’s clocks (850MHz core, 1200MHz memory), but XFX offered that with its HD 5970 4GB Black Edition card. Naturally, this managed to give it the upper hand in the fight with the reference card.
XFX used non-reference cooling to make sure that the card will handle higher clocks. Furthermore, the card comes with 6 video outs and as much as 4GB of memory. While the reference card’s GPU has 1GB at its disposal, this time around it’s 2GB.
