Performance: Compared to 2.40 GHz
If we compare the performance of the Phenom X3 at the same clock rate with a Phenom X4 and a traditional Athlon 64 X2, the benefits of a tri-core processor are shown clearly by the course of benchmark tests.
The Phenom with four cores is 6% faster than the Phenom with three CPU cores at the same clock rate. However, under full load, it requires 36% more energy and costs approximately 10 euros more. When compared to the traditional Athlon 64 X2, the Phenom X3 is roughly 23% faster due to its greater efficiency and the additional CPU core.
