This integer benchmark measures CPU performance using AES (a.k.a. Rijndael) data encryption. It utilizes Vincent Rijmen, Antoon Bosselaers and Paulo Barreto’s public domain C code in ECB mode.
CPU AES test uses only the basic x86 instructions, and it’s hardware accelerated on VIA PadLock Security Engine capable VIA C3, VIA C7, VIA Nano and VIA QuadCore processors; and on Intel AES-NI instruction set extension capable processors. The test consumes 48 MB memory, and it is HyperThreading, multi-processor (SMP) and multi-core (CMP) aware.
