You can run the Phoronix test suite before and after enabling them. There's not a lot of data on the various recent AMD platforms, presumably because of the smaller market share especially until recently. I imagine there's a large difference between mitigations=on and mitigations=off on the pre-Zen AMD platforms and a smaller difference between the two on the most recent AMD generation.
