AMD Announces Radeon HD6990M Mobile GPU, Shatters NVIDIA GTX 580M Records

The seesaw race between AMD and NVIDIA for top performance crown once again tips in AMD’s favor with the announcement of their latest mobile graphics part, the Radeon HD6990M. NVIDIA had claimed the top speed crown with the GTX 580M mobile graphics part barely 3 weeks ago, but today already finds itself outclassed by the latest Radeon part.

The Radeon HD6990M is based on the desktop Barts XT core found in desktop Radeon HD6850/HD6870 GPUs. The previous HD6970M part was also based on the Barts XT core, but had a lower clock speed and some Stream processors disabled. The new HD6990M part sees a boost in core clock from 680MHz in the HD6970M to 715MHz and increases the Stream processors from 960 to the full 1120 units. Texture units are also boosted from 48 to 56.

The AMD provided Powerpoint slide (above) synthetically generated performance metrics using lower clocked, equivalent desktop parts to the AMD and NVIDA mobile parts running at 1920 x 1200 resolution. What it shows is a clear performance advantage of AMD’s new mobile Radion HD6990M over NVIDIA’s GTX580M part. The results are expressed in relative percentages against a normalized NVIDIA score. In short, it’s a whole lot of Radeon Whoop Ass over NVIDIA.

Either part will handle 1080p video and gaming without a hitch and will ligthen your wallet by several bills. But if you absolutely, positively must have bragging rights to the fastest mobile GPU under the sun, AMD has a part with your name on it.
