Data Archiving and Compression 

WinRAR cannot run in more than four execution threads when archiving data and cannot utilize the extra cores of a six-core CPU or Hyper-Threading technology. As a result, the Core i5-760 is much faster than the Phenom II X6 1055T and is almost as fast as the Core i7-860.

The TrueCrypt encryption tool, on the contrary, can run in multiple parallel threads effectively: the Core i5-760 is 26% behind the Core i7-860 and 54% behind the Phenom II X6 1055T.
