Performance tests were conducted in a system based on the motherboard Gigabyte GA-Z77X-UD3H, processor Intel Core i7-3770K (4.5 GHz) and 8 GB DDR-2133. Updated accelerator is about 7% faster than normal Radeon HD 7970, and on average is a competitor to the GeForce GTX 680.
Curiously, while working at a frequency of 1075 MHz, Radeon HD 7970 GHz Edition uses about 10 watts less power when compared with earlier models Radeon HD 7970 operating at similar frequencies. Related Products :
