We're not far away from going 'out with the old and in with the new' as the launch of the 4k series of AMD graphics card close in upon us. This month, looking through the release notes for the latest incarnation of Catalyst drivers we see that a few performance increases have been promised.
Maybe AMD are hard at work on the 4k series of cards and have figured out how to extract some more power out of the aging 3k ones in the process.
Call of Juarez DX10: Performance increases up to 12% on systems containing an ATI Radeon HD 3xx0 series of product
Halo: Performance increases by 10-30% across all of the supported ATI Radeon series of products
Lost Planet DX10: Performance increases from 5 to 35% on systems containing an ATI Radeon HD 3xx0 series of product
Stalker DX9: Performance increases by 20-50% when HDR is enabled in the game; across all ATI Radeon HD38x0 series of products
World in Conflict DX10: Performance increases up to 25% on systems containing an ATI Radeon HD36x0 and/or an ATI Radeon 38x0 series of product. Higher performance gains are noticed on systems containing an ATI Radeon 3870x2 series of product
We'll see if these performance increases translate to any of the games we use.
