What is the latency and throughput of the RDRAND instruction on Ivy Bridge?

Question

I cannot find any info on agner.org on the latency or throughput of the RDRAND instruction. However, this processor exists, so the information must be out there.

Answer 1

I have done some preliminary throughput tests on an actual Ivy Bridge i7-3770 using Intel's "librdrand" wrapper and it generates 33-35 million 32bit numbers per second on a single core.

This 70M number from Intel is about 8 cores; for one they report only about 10M, so my test is over 3x better :-/
