TPU writes leaked benchmark figures indicate that AMD's upcoming Radeon R9 290 will be able to beat NVIDIA's GeForce GTX 780. The 290 is a more affordable version of the 290X, it features 2560 stream processors, 160 TMUs, 64 ROPs, a 512-bit memory bus and 4GB GDDR5. The clockspeeds are said to be 947MHz for the core and 5000MHz for the memory. Pricing is rumored to be around the $449 mark but more information should arrive on the launch day, which is October 31st.
If these performance numbers posted by credible reviewers at OCUK hold up, then AMD could have a second, more affordable graphics card for you, which outperforms NVIDIA's GeForce GTX 780, at least in synthetic benchmarks. In a brief performance run that spans synthetic tests, which included Unigine Heaven 3.0 at 1080p and 1440p resolutions, with normal level of tessellation; 3DMark 11 (performance preset) and 3DMark Fire Strike (both Normal and Extreme); the card we believe to be R9 290 (name blurred out in the graphs) is consistently faster than the GeForce GTX 780 reference, in the same bench.
