Like our review of the AMD Athlon II X4, it's difficult getting the modern comparisons for the Phenom II X2 555 BE. Intel has largely left the lower priced segments to its older Core 2 processors and recently the Clarkdale based Pentium G9650. Since we don't exactly have some of these processors lying around in our lab, we had to make do with the ones we tested for the Athlon II X4 review, namely the Core 2 Quad Q8200 (US$160) and the Pentium Dual-Core E6500 (US$87). Of course, we'll also compare the Phenom II X2 555 BE with the Athlon II X4 630 and 620. With the release of the Athlon II X4 635, the Athlon II X4 630 has been reduced in price to US$99, the same price as the Phenom II X2 555 BE, so that makes for an interesting comparison point too.
By downclocking the Phenom II X2 555 BE, we have obtained the results of the Phenom II X2 550 BE for reference. Two systems (AMD and Intel), with similar amount of memory and the same graphics card and hard drive are used to keep the results comparable in our benchmarks. Both were running Windows XP SP2. The full system configurations are:
