The AMD Phenom II X3 also struggled with image sharpening compared to the Intel Core i7 920. However, it is important to note that the Core i7 system was using its triple memory channel controller compared to the dual channel memory with the Phenom II. While the Phenom II X3 710 and Core i7 920 are both, respectively, at the lower end of AMD and Intel's newest processor families, the Core i7 920 does cost significantly more than the AMD tri-core product.
Turning to testing out GCC 4.4.0 on Ubuntu 9.10 Alpha 1 with the Linux 2.6.30 kernel, the results were interesting. The Phenom 9500 was by far the slowest and running at its stock speeds the Phenom II X3 was 60% slower than the Core i7. When overclocking the Phenom II X3 to 3.51GHz, it was slightly faster than the Core i7 at its stock speeds.
The 3.51GHz Phenom II X3 was almost twice as fast as the Core i7 920. However, the Phenom II X3 at 2.60GHz was almost twice as slow as the Core i7 system.
