The results of our media encoding test are different. First, the Celeron D 325 is faster in such tasks than the Sempron 2600+ for Socket 754. Second, the numbers suggest that the Lame and MainConcept codecs are very sensitive to the CPU clock rate, so the older Socket A Sempron 2600+ (at 1.83GHz clock rate) finds itself ahead of the new Sempron 2600+ (1.6GHz clock rate).

When overclocked to 2.5GHz, the Sempron 2600+ easily leaves behind all midrange Athlon 64 CPUs that are clocked at 2.2GHz and lower. Intel’s NetBurst architecture is better suited for processing streaming data, so the overclocked Sempron 2600+ is almost everywhere slower than the Pentium 4 3.4E and sometimes slower than the Celeron D 325 overclocked to 3.4GHz.

The computational capacity of processors with AMD’s K8 architecture shows itself in mathematic modeling tasks. The frequency is also important here, though. That’s why the new Sempron 2600+ can only outperform the Celeron D 325. When overclocked to 2.5GHz, this Palermo-core Sempron finds itself at the top of the diagram.

It’s similar in the final rendering task in 3ds max 7. We should keep in mind the fact that this application makes an efficient use of Hyper-Threading technology. That’s why the overclocked Sempron 2600+ cannot catch up with the Pentium 4 3.4E GHz.
