Memories both forms with GDDR5 an advantage in terms of clock rate of 11% for the Radeon HD 5970 solution. The analysis of the component GPU is generally more simple, the number of stream processors is doubled in the new Radeon HD 5970, while the clock sees a slight margin of advantage for the Radeon HD 4870 X2 (750 MHz against 725 MHz).

Appears possible superiority of the Radeon HD 5970 compared to Solution Radeon HD 4870 X2 will be justified primarily by increased capacity GPU rather than the higher bandwidth of video memory. the frames are fact lower than the Radeon HD 4870 X2, radically changing in favor of newer cards by switching to 2560x1600 frames. The margin of advantage the Radeon HD 5970 varies significantly depending on the resolution, from a minimum of 21% up to 37% at the higher resolution.
