The following table shows the reported STREAM speeds by processor/RAM for a few servers, as the number of cores utilized increases. All except the one Opteron model (featuring eight sockets of six core processors) are Intel systems. RAM included here is all double data rate synchronous dynamic random access memory (DDR RAM). The main two standards in use in current hardware are DDR2 and DDR3, and the RAM DDR column shows which standard is used and what clock speed the memory is running at. The performance numbers shown for different total core counts are in units of Mbps:
