AMD preps three new Radeon HD 7900 series parts

TechPowerUp delivers news that AMD is working on three new Radeon HD 7900 series SKUs. This includes the dual-GPU Radeon HD 7990, the Radeon HD 7970 GHz Edition and the Radeon HD 7930. The 7990 is reportedly delayed until August to make it perform within "acceptable" range of the GeForce GTX 690, while the Radeon HD 7970 GHz Edition could be just around the corner. The 7930 on the other hand is expected after June, when NVIDIA's upper-mainstream SKUs become available.

Launch of the Radeon HD 7990 has been facing quite a few delays. We can't imagine technical hurdles with regard to board design, but the performance yield, and performance-per-Watt figures the SKU will have to produce, to ever make it to the market. The HD 7990 has the tough task of performing within an acceptable range of the GeForce GTX 690, on both these fronts.

The Radeon HD 7970 GHz Edition will be NVIDIA's bid to compete with the GTX 680, if merely lowering prices won't cut it for the HD 7970. AMD will raise the reference clock speeds for the HD 7970. Lastly, we're hearing of a new SKU, called HD 7930, codenamed "Tahiti LE". This SKU was first spotted when keen observers were poking around with driver information files. It's likely to be a cut-down 28 nm "Tahiti" GPU. It will be interesting to see how AMD prices it, seeing as how it's a tight squeeze between the HD 7870 GHz Edition and HD 7950.
