HD 5870 VS HD 5970 in Crysis Benchmark

sapphire Radeon HD 5870 Toxic beat His Radeon HD5970in crysis

A 2GB frame-buffer enables the Radeon HD 5870 GPU to breathe when really taxed. Indeed, it's faster than a Radeon HD 5970 - a card that has to share its frame-buffer between the GPUs.

A near-30 per cent performance increase over a generic HD 5870 is down to more than just clock-speed, clearly.
