Hexus found several photos and a 3DMark11 benchmark result of AMD's forthcoming Radeon HD 7770. This 28nm "Cape Verde" chip is expected to hit the market next month for around $150, it reportedly has 896 stream processors, a 1000MHz core, and 2GB GDDR5 memory with a 128-bit memory bus.
Where can we expect the Radeon HD 7770 to slot in? Well, it's too early to say, and we await confirmation of an official specification, but the above card has been benchmarked - on a yet-to-be-released Intel Ivy Bridge system, no less - and scored 3,421 in the 3DMark 11 performance test. By our reckoning, that puts it comfortably ahead of a GeForce GTX 550 Ti, but just behind a Radeon HD 6850. Either way, the first few months of 2012 are going to be hugely interesting as far as PC graphics are concerned.
