It looks like AMD is preparing itself a new GPU, the Hawaii XTX. Right now we have the Hawaii PRO, which is the Radeon R9 290, and the Hawaii XT, which arrives to us in the form of the high-end Radeon R9 290X.
The new Hawaii XTX will arrive in retail form as the Radeon R9 295X, and will feature the full 48 Compute Units - compared to the 40 on the R9 290 and 44 on the R9 290X. Better yet, there will be 3072 cores, this is an increase from the 2816 cores found on the already fast R9 290X. When it comes to TMUs, this will be increased from the 176 on the 290X to 192 on the 295X. The ROP count will stay at 64.
The question now sits with pricing - will AMD be competitive, because these specs will allow the company to compete directly with the GeForce GTX TITAN BLACK Edition, as well as the GTX 780 Ti. Because of the increased specs, we should expect the Radeon R9 295X to arrive with custom cooling from AMD's various partners in SAPPHIRE, MSI, and more.
