Benchmarks and photos of ATI Radeon HD 5750 leak out

On a Taiwanese website, the first photos and benchmarks have surfaced of the HD 5750, a video card that should serve the mainstream segment together with the HD 5770. The 5700 cards have 1120 stream cores on board.

the GPU features according to the Taiwanese forum poster about 1120 instead of the 800 stream processors mentioned in previous posts. The number of 1120 cores means that there are 14 simd engines present, because each consists of 16 thread processors, which in turn are made up of 5 stream cores. Since there are four texture units linked to a simd engine, that also means that there are 56 texture units present. The memory bus was shortened from 256bit to 128bit but the gddr5 memory is clocked at a respectable speed of 4600MHz. As a result, a bandwidth of 73.6GB/s is available. The GPU itself is clocked at 700MHz for the time being.

In the 3DMark06 and 3DMark Vantage benchmarks, the HD 5750 is quite similar to a GTS250. However, the video card is a lot faster than the HD 4770, but the benchmarks are not really representative of real gaming performance. The photos also show that the video card, just like its bigger brothers, the HD 5870 and the HD 5850, also has two DVI, an HDMI and a displayport output. For the power supply, the video card seems to need a single six-pin PCI-e connector. The 5770 and 5750 are expected to go on sale in two weeks, priced at $199 and $149 respectively.
