Compression and Encryption
I decided to replace the WinRAR test with a more repeatable and threaded application – 7-Zip.
TrueCrypt is one of the most popular pieces of software for disk encryption, and it includes a handy benchmark mode to test the capabilities of your processor. Keep in mind that many modern CPUs include AES acceleration which is used throughout TrueCrypt.
Compared to Devils' Canyon, the Core i7-6700K is slightly ahead in pure AES encryption. That difference grows when we dive into the additional encryption methods as well. In that case, Skylake is more than 15% faster than Haswell.
