Data Compression and Encrypting

WinRAR cannot run in more than four execution threads when archiving data, so the overall picture resembles what we’ve just seen in the games. The Phenom II X6 is not as fast as we might expect and falls behind the quad-core products from Intel due to its rather low clock rate that neither the number of cores nor Turbo Core technology can make up for. The Phenom II X4, on the contrary, performs well enough. You should keep it in mind that this quad-core processor is competitive only because AMD positions it as an alternative to Intel’s dual-core models from the Core i5 and Core i3 series. The dual-core Phenom II X2 falls behind even the junior Core i3 series product, indicating that modern processors from AMD and Intel with the same number of cores deliver completely different performance.

Moreover, the dual-core Phenom II X2 560 is inferior to the Core i3-530 even in the TrueCrypt encryption system which is generally favorable towards the Stars (K10) architecture. On the other hand, the Phenom II X4 and Phenom II X6 perform well in the encryption tasks, being much faster than their opponents from the Intel Core i5 series. Here, the quad-core Phenom II X4 970 matches the speed of the more expensive Core i7-980 while the Phenom II X6 is far faster.
