Memory bandwidth benchmarks (Memory Read, Memory Write, Memory Copy) measure the maximum achiveable memory data transfer bandwidth. The code behind these benchmark methods are written in Assembly and they are 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.
The Memory Latency benchmark measures the typical delay when the CPU reads data from system memory. Memory latency time means the penalty measured from the issuing of the read command until the data arrives to the integer registers of the CPU.
Here on the AIDA64 Copy test the Corsairs Vengeance LED 32GB 2666MHz Kit kit gave us 36.280MB/s.
We expected the latency to be a little lower than the 3000MHz kits, and in general a faster kit will have a lower latency, and the 2666MHz Corsair kit gave us a latency of 56.1ns.
The Corsairs Vengeance LED 32GB 2666MHz Kit kit ran a 36.963MB/s on AIDA’s read benchmark.
The write benchmark didn’t slow the Corsair kit down any and it hit 39.817MB/s .
