AMD plans to include one more member to its family of Radeon R9 cards that will be a faster version of the recently launched Radeon R9 285. The new video card, when launched, will carry the Radeon R9 285X brand name and will have some nice hardware improvements.
The Radeon R9 285X will be based on the so-called Tonga XT GPU made on 28 nm tech process and this is the reason why the new card will offer 2048 stream processors instead of the 1792 found in the R9 285. In addition to that it will have 3 GB of GDDR5 memory, a 384-bit memory bus, 128 TMUs and 32 ROPs and 288 GB/sec of memory bandwidth. Unfortunately we do not know the clock speeds of the GPU and the memory but we suspect that the memory will work at 6000 MHz effective. The new card fully supports DirectX 12, API Mantle and TrueAudio and needs power via two installed 6-pin PCI-E Power connectors.
The Radeon R9 285X will be launched very soon. The card is expected to cost around USD 300.
