Compression and Encryption
I decided to replace the WinRAR test with a more repeatable and multi-threaded application – 7-Zip.
TrueCrypt is one of the most popular pieces of software for disk encryption with a handy benchmark mode to test the capabilities of your processor. Keep in mind that many modern CPUs include the same AES acceleration which is used throughout TrueCrypt.
As the microarchitecture has improved, so does support for advanced features like AES encryption. In this case, the Core M 5Y70 with the updated Broadwell design is able to pull in the best score at 1.5 GB/s throughput, 15% faster than the Core i5-4200U and 69% faster than the Atom Z3770.
