Intel’s Mighty Dual Xeon Beast – V8 Platform Preview

WinRar v3.70

RARLAB – WinRar v3.70 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 QX6700 we noticed that it used roughly 80-84% of the 2.66GHz quad-core processor, so it makes for a decent SMP benchmark.

When running WinRAR on the eight cores using a pair of Xeon X5365 processors, the CPU utilization was even lower at roughly 75-78%, which is something interesting to point out. Also, notice that the performance decreased when moving from the quad-core system to the eight core system. Lets a look at the multithreaded testing results and see how things turned out.

The Intel Core 2 Extreme QX6700 processor easily took the lead thanks to the fact that it has better memory bandwidth thanks to its low latency DDR2 modules versus the FB-DIMMs that the Xeon workstation board uses.
