Performance

SYSMark 2004 SE

As usual, we will test the performance of our systems in “general-purpose” application with the SYSMark 2004 SE testing suite. This benchmark emulates the user’s work in popular applications with multi-tasking of the operating system actively involved.

As we see, the new dual-core Intel processors work much faster than the older ones based on Smithfield core. It even allows Pentium Extreme Edition 955 to outperform Athlon 64 X2 4800+, which has always been unattainably fast for Intel dual-core processors.

PCMark05

PCMark05 is another popular test suite for “general” system performance. Since it creates multi-threaded workload during work, the CPUs with two cores perform the best of all in it.

First of all I would like to point out the high performance of the overclocked Pentium Extreme Edition 955. By raising the clock frequency of this processor to 4.26GHz, we put this CPU into the leading position in many benchmarks. And PCMark05 is no exception. However, even when Presler based CPU works at its nominal speed, the results appear quite high, so that it even surpasses the top competitor’s solution – AMD Athlon 64 X2 4800+. In fact, there is nothing surprising about it, as this test is optimize for NetBurst architecture.
