Memory Copy

 

This benchmark measures the maximum achiveable memory copy speed.  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, AVX, and AVX2 instruction set extension.  For each processing thread the benchmark copies a 32 MB sized, 64 KB aligned data buffer into another 32 MB sized, 64 KB aligned data buffer through the CPU.  Memory is copied 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.
