AMD Radeon HD 6750 and 6770 specifications leaked

Posted on Monday, September 27 2010 @ 18:49:49 CEST by


VR Zone found a slide with the specifications of AMD's Radeon HD 6750 and Radeon HD 6770 graphics cards. The specifications reveal these cards will get close to the performance of the current ATI Radeon HD 5800 series.
The chart also reveals details about the SIMD structure of the Barts core. The Evergreen series SIMD featured 16 VLIW-5 clusters of 5 shaders each, for a total of 80 SP. Each SIMD also featured 4 TMU. The top part, Cypress XT / HD 5870, thus comprised of 20 SIMD, which is 320 clusters = 1600 SP and 80 TMU. The first major change, that has already been widely speculated, is the structure of each shader cluster. It now features only 4 shaders. However, each cluster is now more efficient, providing equal or greater performance for a smaller die area. Each SIMD now oddly consists of 20 such VLIW-4 clusters. (8, 16, 32... are usually expected) The total shaders per SIMD, thus remains the same - 80 - though they are arranged differently. Barts XT features 16 SIMD, or 320 clusters with 4 shaders each. I.e. a total of 1280 SP. The TMU per SIMD ratio remains constant at 4. Hence, Barts XT features 64 TMU. If these specifications are true, the end result is a HD 6770 card which soundly defeats a HD 5850, as recent rumours suggest, and gets very close to a HD 5870.
Hit "read more" to see the full specifications. The Radeon HD 6750 reportedly has a 114W TDP while the Radeon HD 6770 consumes up to 146W.
