Now at Computex, AMD assumed the wraps off of 2 highly expected processors: the Athlon 2 X2 250 and the Phenom 2 X2 550 Black Version. Both are founded on AMD's 45nm SOI function with the key dissimilar being the amount of L3 cache. The Phenom 2 X2 550, codenamed Callisto, acquires the complete 6 MB cache of the Phenom II family and will serve as AMD's fresh flagship double-core processor. The Athlon II X2 250, on the other hand, is based on the new native double-core Regor die that omits the L3 cache fully and targets the mainstream segment. Benchmark Reviews was fortunate to receive samples of both processors and now we can officially share with you our answers. In this review, we focus on the Phenom 2 X2 550 BE HDZ550WGIBOX.


Based on the similar 45nm STARS micro-architecture as the remains of the Phenom 2 family, the X2 550 BE should not only be quicker, but too more sufficient than AMD's last 65nm Kuma double cores. For example, posts a nice 2.8 GHz

clock velocity and 2 MB L3 cache, but at the price of a 95W TDP. The new Callisto-based X2 550 BE, however, arrives in 300 MHz higher at 3.1 GHz with a Six MB L3 cache and a TDP of just 80W.


Of course, function and sufficient do come at a cost. In this case, a Phenom 2 X2 550 BE will set. That positions it toward the upper-mainstream market, only under the Phenom 2 X3 family. On the Intel side, its closest competitors will be the Pentium E5400 and Core 2 Duo E7400. Fortunately, we have an E7400 on hand for comparison. Read on to discover how the X2 550 stacks up oppose this and various other processors.
