The popular synthetic benchmarks also react positively to the architectural advantages of the Socket 939 Sempron over its Socket 754 analog (particularly, a higher memory bandwidth).
The memory subsystem performance influences the speed of the reviewed processor the most in ScienceMark 2.0. The new Sempron 3000+ is very close to the Athlon 64 3000+ which enjoys a single architectural advantage over it – a larger L2 cache.
WinRAR yields an opposite picture: the single-channel memory controller of the Socket 754 Sempron has a lower latency compared with the dual-channel controller of its Socket 939 counterpart. That’s why the transition of the Sempron from Socket 754 to Socket 939 brings about a certain performance hit in this particular test.
The memory bandwidth is most important for video encoding tasks and the Sempron 3000+ with a dual-channel memory controller is much faster in applications of that type than its Socket 754 analog.
