AMD is reportedly revising their reference design of the HD 5770 video card. New PowerColor, Sapphire and MSI cards have been pictured, and other board partners are expected to soon follow suit.
The new design looks like it was brought in as a cost saving measure. As you can tell from our review of the HD 5770, the 'old' HD 5770, as we might want to call it now, looked like the little brother of the HD 5870, with a similar cooler on it. The 'new' HD 5770 uses a the same sort of cooler as found on the HD 5750 -- one that uses less metal.
The cooler isn't that only thing changed either; the PCB has been shifted around a little bit. We'll have to wait to get our hands on one for testing before we are able to say for sure that this smaller cooler is able to handle its cooling duties as well as the original design.
However one thing will remain the same: the performance level. The revised HD 5770 has the same specs.
