the XFX Pitcairn cooler performs on par with Powercolor PCS+ , likely due to the smaller actual heatsink (the heatsink doesn't even cover the PCB). Not saying it's great, but it's quieter than the jet engine that is the XFX 7950 likely due to a slower fancurve.
Also there was supposedly a BIOS update to get a more aggressive fan curve
^ runs hotter but is quieter, so it's a fan curve thing... 34dB at 10cm
^ ASUS had bad die contact I believe
It's no sapphire though. (26°C hotter when OCed)
My point was it was a extremely poor design for Tahiti, while it was simply a poor choice of fin area for Pitcairn.

Also, look at the 6000 series, they contain VLIW5 and only 6900 was VLIW4. The 7000 series is mostly VLIW instead of GCN as well IIRC. As long as the price/performance is there, I don't mind rebrands. Too bad the supposed 7970 rebrand lacks crossfire fingers - that probably rends it impossible to crossfire with my 7970
HD7000 series is all GCN except OEM ones like HD 7670 or HD 7570 that usually see in HP/Dell PCs. There's also the HD 7000 series G (Trinity) integrated graphics which are VLIW4 and not GCN.
HD7730 / HD 7750/7770= Cape Verde
HD7790 = Bonaire
HD7850 / HD 7870 = Pitcairn
HD7870XT/HD7950/Hd7970 = Tahiti
Basically everything you can buy in a store and put into a desktop motherboard PCI-e slot is GCN.Edited by AlphaC - 9/26/13 at 6:42pm
