Athlon II X3 455, Phenom II X2 565 and Phenom II X6 1100T
 

AMD is usually pretty aggressive with turning process tweaks and yield improvements into new products. Just two months ago AMD gave us the Athlon II X3 450 and the Phenom II X2 565, today we're getting speed bumps of both of those parts. The Athlon II X3 455 runs at 3.3GHz, up from 3.2GHz and costs the same $87. You get an additional 100MHz for free. The chip hasn't changed otherwise. You get a quad-core die with one core disabled, no L3 cache and a 512KB L2 per core.
