Having covered the $549 and $449 territories in January with the Tahiti-based Radeon HD 7970 and HD 7950, AMD is bringing its latest generation GPU to mainstream brackets today. The new Radeon HD 7770 and 7750 use the same 28nm design process and Graphics Core Next (GCN) architecture as the 7000 series flagship, albeit in more affordable configurations.
The move to 28nm lets AMD squeeze 1500 million transistors into a 123mm2 die. In addition, the HD 7700 series die is 26% smaller than the HD 6770, while containing 44% more transistors. As impressive as those figures are, gamers will be more excited to see AMD's prices: the HD 7770 is $159 -- in line with the GeForce GTX 560 -- and the HD 7750 is even cheaper at $109, combating the GTX 550 Ti.
