Report: Specifications of AMD's Hawaii GPU Surface

A report from a German news site,, has shed some light on the specifications of AMD's upcoming 'Hawaii' GPU. So, without further ado, let's list 'em!

For starters, the chip will supposedly feature up to 2816 stream processors, all of which will be split among 44 different clusters. This means that each disabled cluster takes along 64 stream processors for weaker cards. In all likelihood, the Hawaii chips will feature either 32 or 48 ROPs along with about 176 TMUs. The chip will be built on the 28 nm lithography and manufactured by TSMC. It'll feature the GCN 2.0 architecture, as well as support for DirectX 11.2. The GPU is expected to be clocked at 900 MHz or above. The memory interface will be a 384-bit wide memory interface, carrying GDDR5 memory, though no reference capacity was mentioned in the report.

The report also indicates that it expects the performance of the flagship 'R9 290X' card to be between the GTX Titan and the GTX 690. Needless to say, AMD is directly taking on Nvidia's GK110 GPU.

AMD will likely be showcasing the GPUs next week, with sales starting around the mid-to-end of October, starting with the Radeon R9-290 (Hawaii Pro) and the Radeon R9-290X (Hawaii XT).
