Beyond the fact that the Powercolor site still shows the press release stating that it fully unlocks the shaders, there actually are several reviews that explicitly demonstrate it. Including one iirc that actually shows performance metrics between both shader numbers.

Please someone with this card test this. He was very curtain these are guaranteed to unlock shaders, but will not 'flash'
This is awesome if true!!! Can anyone else test this? Mine won't arrive until tomorrow or the next day.
Coincidentally I'm going to try to find that review I referenced above. Now that I think about it, I think they may have actually stated that switching the BIOS, by itself, only raised the clock speed. They then reinstalled the drivers for the shaders to unlock. The reason it strikes a bell with me is because when talking about the performance metrics, I actually recall them stating that simply going to 880MHz did little in terms of performance increases ... but the shader unlock yielded around 9% or so. Why would they have a 880Mhz metric with the traditional shader count unless it does occur as you describe?Edited by Raistlin_HT - 3/3/11 at 12:29pm
