Radeon HD 5750 performance leaked
AMD's first mainstream graphics chipset in its ATI Radeon HD 5000 series has been leaked with photos, specifications and even performance tests. The reference model seen by Chinese site MyMyPC is a dual-slot card but has a unique teardrop-shaped cooling system. It should be a slightly scaled-back version of the 5800 line with 1,120 effects cores (versus 1,440 for the 5850), a 700MHz core (down from 725MHz) and an unknown amount of 1,150MHz GDDR5 memory.
The 5750 would be treated as a faster card than the 4700 series is today and would ultimately replace the once high-end Radeon HD 4870 in the ATI catalog. A faster-still model, the 5770, should replace the 4890. Both should support all the same software features, ranging from newer DirectX 11 and OpenGL visual features to multi-display Eyefinity and general purpose computing through DirectCompute and OpenCL.
Early testing appears to bear out the claims. In the synthetic 3DMark benchmark, the new graphics processor would outperform both the Radeon HD 4770 as well as some cases cards in an entirely different speed segment, such as the Radeon HD 4850 and NVIDIA's GeForce GTS 250.
The 5700 series is unofficially believed to be shipping at least in stand-alone cards for October and would have the 5750 sell for $150 while the upgraded 5770 would cost $200.
