Tom's Hardware: "A few months ago, we compared the Phenom II X2 555 to Intel's Pentium G6950 in both stock and overclocked form. When the dust settled, the results were inconclusive after we enthusiastically over-volted the Pentium CPU past its limits and into oblivion. Even though the load temperatures were quite cool, the processor died halfway through our benchmarks. Readers also commented in the forums that they wanted to see what would happen if our Phenom II X2 555 could run with its dormant CPU cores enabled."
