Intel Haswell-EP Xeon E5-2600 v3 Server Family Processor Overview

AIDA64 memory bandwidth benchmarks (Memory Read, Memory Write, and Memory Copy) measure the maximum achievable memory data transfer bandwidth.




AIDA64 memory tests show the Crucial DDR4 2133 MHz improving memory bandwidth in the Read and Copy tests.


However, we do not see good scaling in the Write tests. At this time we are not sure why this is; it could be testing software needs updating, or it could be there are issues with the IMC on the E5 v3's processors. We plan to test this further to see if we can spot just what the issue might be.


DDR4 also offers improvements in latency over DDR3, which we saw around 90-103ns. With DDR4, we see a big improvement with latency dropping to around 77ns. Faster memory and lower latency with higher capacities offer higher performance for memory driven applications.
