Over the last few months AMD has continued to ramp up frequencies on their current bread-and-butter Phenom II processor line-up to the point where they're now flirting with the 4GHz mark. The Phenom II X4 980 Black Edition marks the release of AMD's highest clocked processor yet. The new quad-core Phenom II X4 980 Black Edition's default clock on all four of its cores is 3.7GHz. Like previous Deneb-based Phenom II processors, the X4 980 BE sports a total of 512K of L1 cache with 2MB of L2 cache, and 6MB of shared L3 cache. Performance-wise, for under $200, the processor holds up pretty well versus others in its class and it's an easy upgrade for AM2+ and AM3 socket systems."
