In this benchmark the Phenom X4 doesn't really impress, in a clock-to-clock comparison to chip can't beat the Core 2 processors and most rumours indicate AMD isn't even planning to release a 3GHz Phenom X4 processor this year or in early 2008. If this benchmark is a good indication of the performance of the K10 it seems that AMD will need to agressively price their Phenom CPUs to compete with Intel.
