What’s different? Well, it has absolutely no fan and the memory chips are relocated on the backside of the card.
The PCB is a clear departure from AMD’s Radeon HD 7770 reference design.
As we said, the memory has been relocated on the back of the card and the chips are cooled by a metallic plate that also gives the card an increased structural integrity.
There seem to be only four heatpipes running through the cooler, but Sapphire is confident that those are enough to cool a fully fledged AMD Radeon HD 7770 GPU.
