NVIDIA is being remarkably coy about divulging any details for its upcoming super-duper GeForce GTX 590 dual-GPU graphics card. Indeed, company representatives don't even acknowledge the existence of such a model.
AMD has no such inhibitions in handing out reference Radeon HD 6990 cards - an also-dual-GPU card that's primed to fight the GTX 590 - to its range of partners. A perusal of the CeBIT stands revealed no less than six partners showing the graphics card in its bulky glory.
The busy CeBIT trade show provided an opportunity to quickly sneak a look at the Catalyst Control Centre on what appeared to be a wholly reference HD 6990.
Bear in mind that some information has been blanked to protect the identity of the partner, but it's clear that CCC is reporting a core speed of 800MHz and an effective memory clock of 'just' 4,500MHz. These are significantly lower than a Radeon HD 6970, suggesting, tenuously, that the dual-GPU card may not be quite as monster-ish as first thought.
Then again, these are pre-mass-production cards and CCC's figures may well be incorrect. Let us know if you think the HD 6990 will come in at faster speeds than those reported here.
