MojoKid writes "AMD has launched their new top-end Radeon R9 290X graphics card today. The new flagship wasn't ready in time for AMD's recent October 8th launch of midrange product, but their top of the line model, based on the GPU codenamed Hawaii, is ready now. The R9 290 series GPU (Hawaii) is comprised of up to 44 compute units with a total of 2,816 IEEE-2008 compliant shaders. The GPU has four geometry processors (2x the Radeon HD 7970) and can output 64 pixels per clock. The Radeon R9 290X features 2816 Stream Processors and an engine clock of up to 1GHz. The card's 4GB of GDDR5 memory is accessed by the GPU via a wide 512-bit interface and the R290X requires a pair of supplemental PCIe power connectors—one 6-pin and one 8-pin. Save for some minimum frame rate and frame latency issues, the new Radeon R9 290X's performance is impressive overall. AMD still has some obvious driver tuning and optimization to do, but frame rates across the board were very good. And though it wasn't a clean sweep for the Radeon R9 290X versus NVIDIA's flagship GeForce GTX 780 or GeForce GTX Titan cards, AMD's new GPU traded victories depending on the game or application being used, which is to say the cards performed similarly."
