In the Performance Mainstream segment of the market things are not that different. Clearly AMD's latest expansion with the Barts architecture came at the right time. The Radeon HD 6870 and the Radeon HD 6850 both manage to outperform not only the GeForce 460 1GB but also the GeForce GTX 460 768MB. It must be noted that the Radeon HD 6870 enjoys an impressive 35% lead over its opponents in this category.
It is no wonder that the Radeon HD 5770 has no competition in the Mainstream category. The GeForce GTS 450 can only achieve an honorable draw with the Radeon HD 5750 at only 690 3DMark11 points. The entry-level Radeon HD 5670 has no problems outperforming the GeForce GT 430 which is the slowest card in our Extreme preset benchmarking. Although its score of 336 points looks ridiculously small, we can remember the times when entry-level graphics cards couldn’t pass an earlier version of 3DMark at all. So, the little Fermi is doing quite fine for its price.
