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.
Thanks to the improved AES performance of Haswell, the Core i7-4770K is 24% faster than the Core i7-3770K but is still slower than the 6-core Core i7-3970X SNB-E. In our non-AES accelerated tests the AMD FX-8350 does very well and actually beats out the stock speed Haswell by a small margin.
