AMD Phenom II X4 955 Black Edition 3.2 GHz Socket AM3 Processor Review
9 August 2009
Summary: The 3.2GHz AMD Phenom II X4 955 Black Edition is the companies' latest quad-core processor, and it's being released in tandem with a new memory tuning tool called Black Edition Memory Profiles, or B.E.M.P. for short.
Conclusion: While the X4 955 Black Edition did not make it in time for the initial Phenom II launch, it's definitely a welcome addition. The new chip rounds out the Dragon Platform refresh and can now take its place as AMD's new flagship processor.
Pros: Highest Phenom II clock speed yet, AM3 & DDR3 support, Unlocked multiplier, 8MB of total cache, AMD OverDrive 3.0, Excellent price/performance
Summary: That, I think, leads us to our conclusions, which ought to be fairly straightforward. The performance contest between the Phenom II X4 955 and the Core 2 Quad 9550 is crazy close, and even the X4 955's one apparent weakness, a higher power/thermal rating, turned out to be a non-issue in our testing.
