RARLAB – WinRar v3.71 has a multithreaded version of the RAR compression algorithm, which improves the compression speed on computers with several CPU, dual core CPU and processors with hyperthreading technology. Multithreading is enabled by default, but you can disable it in “General” part of “Settings” dialog.
When we ran WinRAR on the Intel Core 2 Extreme Processor quad-core processor, we noticed that it used roughly 80-84% of the available cores, so it makes for a decent SMP benchmark.
Benchmark Results: The Intel Core 2 Extreme QX9770 processor easily took the lead on WinRAR 3.71 by beating out the rest of the processors.
Futuremark’s 3DMark06 has a built-in CPU test is a multi-threaded DirectX gaming metric that’s useful for comparing relative performance between similarly equipped systems. This test consists of two different 3D scenes that are processed with a software renderer that is dependent on the host CPU’s performance. Calculations that are normally reserved for your 3D accelerator are instead sent to the CPU for processing and rendering. The frame-rate generated in each test is used to determine the final score.
As expected, 3dMark 2006 CPU test shows us that the Skulltrail system just plain wipes up the floor with our other two CPUs represented here as it just totally out paces them by about 30% and more in score.
