Performance Rating

The Radeon R9 280X2 was a graphics card by AMD. Built on the 28 nm process, and based on the Tahiti graphics processor, in its Tahiti XTL variant, the card supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_1, which can be problematic with newer DirectX 12 titles. The Tahiti graphics processor is a large chip with a die area of 352 mm² and 4,313 million transistors. Radeon R9 280X2 combines two graphics processors to increase performance. It features 2048 shading units, 128 texture mapping units, and 32 ROPs, per GPU. AMD has paired 6 GB GDDR5 memory with the Radeon R9 280X2, which are connected using a 384-bit memory interface per GPU (each GPU manages 3,072 MB). The GPU is operating at a frequency of 950 MHz, which can be boosted up to 1000 MHz, memory is running at 1500 MHz (6 Gbps effective).
