7-zip 9.2
7-zip has been added to our test protocol. In contrast to WinRAR, this application is highly multithreaded if its highest performance algorithm, LZMA2, is used. We measured the time required to compress a large volume of files.
The large L3 cache combined with quad-channel memory allows the 3960X to open up a record lead of 62.4% over the 2600K!
The gain on the 990X was however only 7.4%.
WinRAR 4.01
The same files were compressed in WinRAR using the most demanding RAR algorithm ("Best").
Unfortunately WinRAR doesn’t really use more than two cores and the 3960X therefore only has a 12.7% lead over the 2600K.
The 990X is however further back, with the gain for the LGA 2011 platform rising to 22.7%.
