The Radeon R9 380X has a fully-functional AMD Tonga GPU with all 32 compute units / 2048 shader processors enabled. AMD's reference specifications call for 970MHz+ engine clock with 4GB of 1425MHz GDDR5 memory (5.7 Gbps effective). Typical board power is 190W and cards require a pair of supplemental 6-pin power feeds. The vast majority of the Radeon R9 380X cards that will hit the market, however, will likely be custom models that are factory overlcocked and look nothing like AMD's reference design. The Radeon R9 380X, or more specifically the factory overclocked Sapphire Nitro R9 380X tested, performed significantly better than AMD's Radeon R9 285 or NVIDIA's GeForce GTX 960 across the board. The 380X, however, could not catch more powerful and more expensive cards like the GeForce GTX 970. Regardless, the Radeon R9 380X is easily the fastest graphics card on the market right now, under $250.
