PCWizKid has been testing for a long time now each generation of AMD CPU's and their climbs to greater performance and clock speeds. Today we are fortunate to review what AMD claims is the fastest default clocked Dual Core CPU with the Phenom II X2 555 Black Edition. Last year we saw a tremendous surge in mainstream Phenom II CPU's from AMD with also the release of lower power consumption Athlon II CPU's. The Phenom II X2 555 BE is actually a newer faster revision of the Phenom II X2 550. It is also a 45nm, 80Watt CPU but comes clocked at a default 3.2 Ghz which is truly fast! As usual this CPU uses the AM3 socket and is backwards compatible with AM2+ motherboards (check your motherboard manufacturer for a BIOS upgrade and compatibility) and is thus flexible to be used with either DDR2 or DDR3 memory depending on the motherboard you end up using. Similar to the previous review of the AMD Phenom II X2 550 BE which we did last year we will attempt going beyond the traditional benchmarks that only use default clock settings, but we will unlock all 4 cores and overclock the CPU with minimal increase in the CPU voltage. The Phenom II X2 555 BE is using a revision C3 silicon, which has hardware C1E and promises to give greater overclocking results.

Using the 3.2GHz Phenom II X2 555 BE at default clock speeds felt like its previous 550 model, with one small difference, the overclocking potential is indeed greater. The Phenom II X2 555 at launch is priced at $99 US whereas an Intel Core 2 Duo E8400 costs about $165 US which makes the AMD as always an attractive alternative. PCWizKid was pleased to have been able to unlock all 4 cores of the Phenom II X2 555 which transformed the CPU to a Phenom II X4 (Deneb) CPU and overclocked it also to 3.6Ghz which beat a Phenom II X4 955 in all benchmarks for $65 less! The default clock speed temperatures as seen in the video review are well below the limits. When overclocked and with a good CPU Cooler for a quad core CPU there is potential to reach the 3.8 easily. Again the overall benefits of owning a black edition CPU from AMD prove that its a wise buy for a gaming system which can be turned into a enthusiast system if your lucky to get all the 2 additional cores unlocked. Wheather you unlock or not the CPU Cores the Phenom II X2 555 BE today is a low cost choice for performance on a dual core CPU. PCWizKid gives the Phenom II X2 555 BE recommended award, specially for enthusiats looking to unleash its full potential for the price point of $99 with no doubt an attractive alternative.
