In the first generation the 1600X was a 95w TDP part, with the 1600 being 65w. They shuffle around where the lines are, the numbers aren't always 1:1.

They listed Zen 4 at 65w TDP being 74% more efficient than Zen 3 in their slides, which implies they do want to sell a part at that spec at some point.

If your concern is purely noise/heat and so on, and not budget, then you can just buy one of these chips and apply restrictions to it, given modern chips auto-scale performance. Can feel like a waste, of course, but should result in a very efficient setup.
