AMD Radeon R9 290X

AMD announced the new Radeon R9 290X, its next-generation flagship graphics card. Based on the second-generation Graphics CoreNext micro-architecture, the card is designed to outperform everything NVIDIA has at the moment, including a hypothetical GK110-based graphics card with 2,880 CUDA cores. It's based on the new "Hawaii" silicon, with four independent tessellation units, close to 2,800 stream processors, and 4 GB of memory. The card supports DirectX 11.2, and could offer an inherent performance advantage over NVIDIA's GPUs at games such as "Battlefield 4". Battlefield 4 will also be included in an exclusive preorder bundle. The card will be competitively priced against NVIDIA's offerings. We're awaiting more details.
