AMD and Nvidia have been biting the hands and necks of each other. Now that Nvidia has thrown in a new flagship for their mobile GPU division for extreme gaming laptops with their new GTX580M, AMD is also going to join in the ring.

The outfit just unveiled the Radeon HD 6990M with DirectX11 and HD3D support, and it insists this is the speediest GPU on the block — specifically, up to 25 percent faster than any other GPU that’s been announced to the public. And yes, AMD’s well aware of that 580M. Just like NVIDIA came out swinging, making pointed comparisons to the Radeon HD 6970M, AMD’s got some fighting words of its own: the company says the 6990M can whip the 580M in the benchmark AvP and games such as Batman Arkham Asylum, Dragon Age 2, Shogun 2, BattleForge, Left 4 Dead, Metro2033, Wolfenstein MP, The Chronicles of Riddick, and ET: Quake Wars. We don’t need to remind you that these numbers merely represent the story each company wants to tell. Still, you get the idea: these are the top-of-the-line cards each has to offer at the moment, and they’ll likely be competing for space in your next gaming rig.

As you can imagine, the 6990M joins other Radeon HD cards in supporting the company’s Eyefinity technology, as well as GPU app acceleration. Let it be known, too, that while the 6990M supplants the popular 6970M as far as performance claims go, AMD tells us the 6970M will still be available for the foreseeable future. Speaking of availability, the 6990M will be offered in the Alienware M18x — right alongside NVIDIA’s 580M.

Additionally, you’ll find it packed inside Clevo’s P170HM and P150HM. And you didn’t think we forgot about specs, did you? Head on past the break to find the full PR, along with a handful of technical details straight from the horse’s mouth.
