WinRAR 4.01 and 4.10

Other popular software compression and decompression of data archives. Inside it there is a benchmark utility that compresses a standard file suitable for this purpose; the software will return the compression speed in KB/s. We also performed the tests by turning off core parking in the operating system Windows 7 SP1. You can read our study of the topic at the following link:

Core parking on Windows Seven: WinRAR performance with Sandy Bridge

This benchmark ran within the same application shows a double face. If we look at the result without affecting the parameter of Core Parking it can be seen that the new AMD Bulldozer architecture is able to have a really amazing performance compared to other competitor CPUs, even the Intel top of the range, the i7-3960x. But we note that all Intel CPUs with Hyper Threading in fact have the same performance of CPUs without this technology. In particular we see how the Intel i7-2600K has the same performance with and without HT. This made ​​us go further in our analysis and we have examined the subject (please read the article listed above in this regard).Disabling the Windows core parking, via a registry key, performance have changed for many CPUs, and we rerun the tests especially for Intel CPUs with Hyper Threading, but also we re-ran the tests with the AMD FX-8150 itself.

Setting the operating frequency to 4 GHz there are the same considerations set forth above. Disabling the core parking the performance of the other Intel CPUs with HT increased significantly.
