> given that Ryzen runs in "rage mode" all the time It doesn't. "Rage mode" would be equivalent to Ryzen's PBO. Which is definitely not on by default. It's likely equivalent to just dragging the power limit slider to the highest it goes on MSI afterburner. Letting boost go out of power spec limits, but nothing more. Which can still give decent gains (look at how power starved Ampere is, for example). But the only noteworthy thing here is just it's in the official control panel instead of a 3rd party app.

Small correction - Rage mode increases the power budget but AMD confirmed it does not max out the power budget the same as sliding the slider all the way to the right. Speculation point: because of this I almost wonder if it's equivalent to selecting a higher TDP rather than a warranty violating OC like PBO was. One of the things people railed on Nvidia for was for ever slightly less perf you could get a much lower wattage card that was quieter, maybe this was the response to that?

  PBO basically just selects a higher TDP, too. The warranty violating part of all of these would be you're technically driving the power delivery system beyond what the spec strictly requires. For PBO that'd be your exceeding the spec that AM4 requires from motherboards, which could put you of spec for a motherboard's VRM solution. I don't know if there's a handshake there between the CPU & BIOS to ensure PBO doesn't exceed a given motherboard's specs, though. If there is it'd be hard to claim this would be an actual warranty-violating usage. Rage mode almost certainly respects the vbios limits, so you'll likely see lower-margin cards have basically no improvement from Rage mode, depending on how much they skimped on the power delivery. You'll likely not see an actual push to void warranties as a result, too. Although in both cases (PBO & Rage mode) it's going to be almost impossible for a vendor to actually reject a warranty issue unless you tell them you did this. Afaik nobody is doing something like a blown fuse to keep a permanent record of these feature(s) being used or enabled.
