Memory Write
This benchmark measures the maximum achiveable memory write bandwidth. The code behind this benchmark method is written in Assembly and it is extremely optimized for every popular AMD, Intel and VIA processor core variants by utilizing the appropriate x86/x64, x87, MMX, MMX+, 3DNow!, SSE, SSE2, SSE4.1, and AVX instruction set extension. For each processing thread the benchmark writes a 64 MB sized, 64 KB aligned data buffer from the CPU into the system memory. Memory is written continuously without breaks, using 4 KB page size.
[*NEW*] Since AIDA64 v3.00, the test is HyperThreading, multi-processor (SMP) and multi-core (CMP) aware.
