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 and Intel processor core
variants by utilizing the appropriate x86, MMX, 3DNow!, SSE or SSE2
instruction set extension. The benchmark writes a 16 MB sized, 1 MB
aligned data buffer from the CPU into the system memory. Memory is
written in forward direction, continuously without breaks.
In order to avoid concurrent threads competing over system memory
bandwidth, Memory Write benchmark utilizes only one processor core
and one thread.
Important
note
On AMD K8 class (Athlon 64, Athlon 64 X2, Socket 754/939/AM2
Sempron, Opteron, Turion 64, Turion 64 X2) systems configuring the
Command Rate setting to 1T significantly improves Memory Write
bandwidth and CPU PhotoWorxx scores.
