AMD has just released it’s current flagship card, the dual GPU Radeon 6990 and it didn’t take long for Nvidia to respond with it’s own single-card, dual GPU solution. Meet the GeForce GTX 590.
If the Radeon 6990 is basically two 6970 in crossfire configuration, embedded into a single chip, then the GeForce GTX 590 is basically two GeForce 580 in SLI.
The GeForce GTX 590 is clocked a bit slower than it’s single core brother the GTX 580 at just 607MHz and memory speed of just 853MHz. However, as with the case is with AMD’s Radeon 6990, lowering the card’s clock speeds help trim down this monster’s TDP to just 365W.
