Radeon HD 6790, April 5 Posted on 29/03/2011 at 13:08 by Guillaume
The Swedish site, Nordic Hardware, has just published the specs of the forthcoming Radeon HD 6790. This card, which is slated for release on April 5 is reported to be using an LE version of Barts which already equips the Radeon HD 6850 and 6870 (Barts Pro and XT). Logically then, it could have been called the HD 6830.
Only ten out of fourteeen SIMD groups are active, giving us 160 vec5 units (against 192 and 224 for the 6850/6870) and 40 texturing units (48/56). The GPU is said to be clocked at 840 MHz (against 775 and 900) and memory at 1050 MHz (1000/1050). The GPU is to keep its 256-bit memory bus and the card to use two 6-pin connectors for a TDP of 150 watts, whereas the HD 6850 uses just one. It will be interesting to check the real consumption of the card in practice. This will mainly depend on the quality of the power stages – these are often revised on LE models to keep costs down.
