PowerColor HD 7850 PCS+ 2 GB Review
Packaging & Contents »Introduction
AMD's recently released HD 7800 Series is based on the company's new Pitcairn silicon which uses the GCN shader architecture on a 28 nm process. HD 7850 provides great midrange capabilities beating the Radeon HD 6950 and the NVIDIA GTX 560 Ti.
PowerColor's HD 7850 PCS+ comes with a massive overclock out of the box, upping GPU clock by 140 MHz, to 1 GHz. Memory clock is up to 1225 MHz, so a relatively small increase.
