Comparing the main specs of the 5750/5770 i.e Core Speed, Mem Speed, Shaders, Mem Bandwidth… it looks like they will perform near on equal with each other.

The 5770 will no doubt give higher frames per seconds in games, but probably not much more than 10% of the overall of a 5750…and going by those specs these cards will probably be getting atleast 50FPS at 1920×1080 in the up and coming Modern Warfare 2 anyway.

Hopefully we’ll have more info soon with some reviews and benchmarks to shed some light on my prediction.

I am however very surprised that the 5770 only has 800 shaders, not much of an increase over the 4770s 640.

4770 – 640
4870 – 800

5770 – 800
5850 – 1440
5850 – 1600

Even compared with the 2nd best in the 5800 series, there is a massive gap in shader power between 800 and 1440.

If i was AMD i would of made the 5750 with 800 shaders, and the 5770 with atleast 1000 shaders, as going by thge power requirements above both cards with these revised specs would still be below 150W and still only require x1 6-pin.

Nevermind though, i’m sure the 5700 series is going to be a best selling item for the end of 2009
