The Futuremark PCMark04 test uses the Hyper-Threading technology, so the results of the Pentium 4 processors are higher than those of the Athlon 64. The overclocked Sempron 3100+ can’t win this test for the AMD camp, but it is anyway much faster than the Athlon 64 3400+.
The Pentium 4 CPUs are again at the top of the diagram in the memory subsystem test. They work in systems with a dual-channel memory controller, while the Sempron 3100+ and the Athlon 64 model we tested have a single-channel controller. That’s why the K8 architecture doesn’t show its strength here, but let’s see what we have in other tests.
