AMD in a bid to remain competitive in the desktop market, has unveiled three additional tri-core Phenom processors.

The new Phenom X3 models are the 8750, 8650 and 8450, which have clock speeds of 2.4GHz, 2.3GHz and 2.1GHz respectively. All three CPUs offer a total of 1.5MB of Level 2 cache, 2MB of shared Level 3 cache and a TD of 95 watts. The processors are used in conjunction with the AMD 780 series chip set and ATI Radeon graphics.

The 8750 costs $195, the 8650 costs $165 and the 8450 costs $145. All three processors carry a "50" designation to show that the chips are part of a new batch of silicon called "B3," which corrected a design flaw in the original quad-core processors."In today's market, customers are too often forced to weigh the benefits of one component over another while sifting through one-sided marketing claims," said Leslie Sobon, AMD director of Product and Brand Management. "AMD is the only company in the world that is able to deliver a balanced platform solution without compromise, delivering a thrilling visual experience and powerful multi-threaded application performance."
