28 nm GCN (Graphic Core Next) Architecture
The new and 28nm GCN Architecture with more efficient process technology puts more transistors in less space, enabling a dramatic increase in Processing Power. Crank the settings, devastate your enemies and bear witness to absurdly high frame rates with AMD Radeon HD7000 series graphics card-DirectX 11 has never looked this good. Maximum setting and crazy performance shouldn’t be a compromise. The AMD Radeon HD7900 Series with the new 28 nm GCN Architecture assures that it’s not.

PCI Express 3.0
PCI-Express 3.0 delivers double the bandwidth per lane of PCIe Gen 2 for faster GPU (GPU communication-up to 16GB/sec in each direction), maximizing the performance from your GPU when paired with the latest platforms.

AMD HD3D Technology
