xorbeBoth sides should adjust the names a little more. Golden Platinum Extreme Edition, and nVidia's Founders Extreme Edition.

Platinum Edition is an old ATI Radeon branding from the X8XX series of cards (circa 2004-2005). In those times it was meant for the highly binned high end chips like the R481 (X850 XT Plantinum Edition AGP).

well below my performance target, but dayum that card is sexy!

And I thought my corny joke would be too obvious, heh ...

FinnersHmmm who's going to be the first one to try and unlock this to a 480!, PCB looks the same -2 power phases,.

No copper core to the heatsink seems like taking penny pinching a little to far, the cooler doesn't cool the 480 well enough so leave it the same and hopefully it would have done an alright job on the 470 but no, they have made it even weaker and probably saved about $2.

The purpose of copper in a heatsink is often misunderstood - it's mostly for handling transient heat loads. Aluminum is better at dissipating heat, copper is better at conducting it. The interface between the two metals needs to be supremely good for the small amount of copper in the RX 480 heatsink to be of any use.

The copper basically keeps idle temperatures lower, and reduces spikes in temperatures, but the peak average will be quite similar between the same heatsink in all aluminum.

The 20W lower likely power output of the RX 470 will be easier to cool, so the copper being absent will likely make no difference.
