There have already been a couple of rumors regarding yet another GPU from AMD based on the 28nm Tahiti chip, and according to Expreview.com, it appears that AMD will indeed push this GPU in the Radeon HD 7800 series rather than the Radeon HD 7900 series.
AMD plans to brand the SKU as the Radeon HD 7890. Unfortunately, there are still no precise details regarding the clock speeds or any precise specifications for that matter, but Expreview noted that it should end up around 15 percent faster than the Geforce GTX 660 graphics card. Of course, the new AMD Radeon HD 7890 SKU aims the GTX 660 as its primary competition as it should hit the marker with a similar price tag.
The new SKU is specifically aimed at the upcoming Christmas shopping spree and should fill the gap that AMD currently has in that price range.
