The Radeon HD 7970 is the first graphics card built at a 28nm production process and the first member of its Southern Islands family of GPUs. As its name suggests, the HD 7970 is the replacement for AMD's fastest single-GPU graphics card to date, the HD 6970. The new card increases transistor count from 2.6b to 4.3b, cranks the engine clock speed up from 880MHz to 925MHz, and adds 33 percent more Stream processors, jumping from 1,536 to 2,048. VRAM is also up from 2GB to 3GB with a 384-bit memory interface for a bandwidth of 264GBps but the most important change is in internal architecture, with the new Graphics Core Next setup promising to untap the card's potential to perform more computational tasks (i.e. GPGPU) without sacrificing any of its gaming prowess.
