Performance - CPU-Queen | AES
Queen CPU test
CPU Queen test uses only the basic x86 instructions, it consumes less than 1 MB system memory and it is HyperThreading, multi-processor (SMP) and multi-core aware and thus is a multithreading CPU Benchmark with MMX, SSE2 and SSE3 optimizations.
A good question always is this one, does faster memory have a direct effect on CPU performance. Well, if the program is small enough to run in the memory. Very little.
But even little differences can be measured. Let us demonstrate in the chart above. Yeah I call that a draw. Makes sense as this is a 100% CPU test. But let's do one more.
AES data encryption
For this test we encrypt some precious data. Data encryption has become a sad necessity for responsible data managers. Cryptography is the science of secret codes, enabling the confidentiality of communication through an insecure channel. The AES algorithm uses one of three cipher key strengths: a 128-, 192-, or 256-bit encryption key (password). Each encryption key size causes the algorithm to behave slightly differently, so the increasing key sizes not only offer a larger number of bits with which you can scramble the data, but also increase the complexity of the cipher algorithm. AES encryption is applied in a lot of compressing software like WinZIP.
Again at 100% CPU utilization, we see that the effect of memory here is close to nothing. Makes sense. But now let's fire up more real-world applications.
