Igor's Lab has very similar results as elmor. Appreciate the excessive testing

Concerning AIDA 64, which did not speak about it in the call, but one of the optimizations brought by Zen 2 is the reduction of the writing from a CCD to the IOD of 32B / cycle to 16B / cycle when the writing bandwidth remains fully provisioned at 32B / cycle. Since workloads have little writing, the link does not need to be 32B wide. This choice of design makes it possible to optimize the energy consumption in other parts of the architecture. In other words, with the 3700X and only one chiplet the observed behavior is normal (and on 3900X with two chiplets you will logically observe higher theoretical writing results).
