The Radeon R9 280X was a performance-segment graphics card by AMD, launched on October 8th, 2013. 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.
