Memory Read

This benchmark measures the maximum achiveable memory read bandwidth. The code behind this benchmark method is written in Assembly and it is extremely optimized for every popular AMD and Intel processor core variants by utilizing the appropriate x86, MMX, 3DNow!, SSE or SSE2 instruction set extension. The benchmark reads a 16 MB sized, 1 MB aligned data buffer from system memory into the CPU. Memory is read in forward direction, continuously without breaks.

In order to avoid concurrent threads competing over system memory bandwidth, Memory Read benchmark utilizes only one processor core and one thread.
