AMD has hardly kept quiet on the CPU front these past several months. At the beginning of the year AMD put the nail in Atom's netbook coffin with the Brazos platform, and last month it announced the first shipments of Llano APUs to OEMs. Expect an official launch of Llano to follow sometime in the next two months.

AMD's focus on the mainstream echoes to a certain extent its GPU strategy: focus on the bulk of the customers first, then address the smaller high end of the market. Despite an overly controlling stance on overclocking and issues with B2 stepping 6-series chipsets, Intel's Sandy Bridge (Core ix-2xxx) dominates the high end. AMD will make a go for that market later this year with its Bulldozer architecture. It's still too early for an accurate preview of Bulldozer performance, although the time for such a thing is quickly approaching.

Until Bulldozer's unveiling, the Phenom II remains as AMD's high end platform. Today, that very platform gets a little boost.

Read on for our review of the Phenom II X4 980 Black Edition.

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 560, 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.

The Phenom II X2 565 is an unlocked Black Edition part, also identical to its predecessors. Here you have a quad-core die with two cores disabled, a 512KB L2 per core and a shared 6MB L3. The 565 runs at 3.4GHz, up from 3.3GHz, but the clock increase comes with a $10 price increase.

The six-core Phenom II X6 gets a speed bump as well. The 1100T increases default clock speeds from 3.2GHz to 3.3GHz, and increases Turbo Core frequency from 3.6GHz to 3.7GHz. Turbo Core is only supported on Thuban based processors (currently only Phenom II X6s) and increases operating frequency if half or fewer cores are actively in use.
