I have been running the Ryzen 5900X machines early in the morning for the Universe@home project. They are an astronomy project studying black holes at the moment. The 5900X can do their work units between 30 minutes and 1 hour when running 24 at a time.

I had another look at the cost of upgrading the Ryzen 5900X to Zen 4 and its still rather expensive. In addition there doesn't seem to be any 32GB DDR5 memory modules available that can do 6GHz which is the sweet-spot for Zen 4. There are a few 16GB modules but they don't recommend using 4 memory modules due to timing issues. Another concern is the power consumption that a Zen 4 CPU will use and the additional cooling needed.
