Ahead of AMD’s official unveil of the Hawaii line of GPUs, details, photos, and benchmarks of (probably) the Radeon R9-290X have leaked. The photos and benchmarks seem to confirm that the Hawaii XT (GCN 2.0) R9-290X has 2816 stream processors, split among 44 clusters. There’ll probably be 64 ROPs (render output units), and around 176 TMUs (texture mapping units). The GPU should be clocked at around 900MHz, and there’ll be a fat 512-bit memory bus to GDDR5 RAM. The new R9 GPUs are DirectX 11.2 compliant, while the R7 GPUs don’t seem to be. The leaked benchmarks peg the Radeon R9-290X as equal or slightly faster than Nvidia’s GTX Titan, and around 10% faster than the GTX 780 — strong, and if it’s priced right, it could put AMD back in the driving seat.
