CPU Computation Benchmarks

This suite is a collection of CPU intensive benchmarks

We have used two versions of WinRAR, 4.2 and above introduce significant multi core speedups, which our scores for WinRAR 5 demonstrate. These different versions cannot be compared with each other so we have shown both.

Our numbers show WinRAR is highly optimised already so does not show much improvement on the newer architecture, future updates to support Haswell's updated instructions should improve performance.

7-Zip and WinRAR's built in throughput based benchmarks are replicable PC to PC, User to User. If we setup our own test case which we zip and time, this becomes heavily dependent on the condition of the storage drive and difficult for others to replicate

Fritz is a synthetic benchmark based on a chess game. It utilises the AI from the game to achieve a score. On AMD's first generation Bulldozer architecture, excess of 11,600 is achieved despite also using 8 threads.

We do not test TrueCrypt with AES acceleration disabled as the end-user would never disable this function apart from scientific compression of the way the AES instruction is implemented in a processor. Testing only with TrueCrypt on shows any improvement in AES throughput.

We note TrueCrypt's benchmark is highly sensitive to being cached and much higher cached/burst throughput can be seen. When overclocked to 4.6GHz, Haswell achieves 5GB/s mean throughput.
