only if you disable boost. 88W PPT for AMD's "65W" CPUs at stock.
not a fan of the "PPT" terminology, it's pretty deliberately designed to mislead people and give AMD a mental "cheat factor" in these comparisons.
And no this is not something that "everyone did", in the 5960X/7700K days Intel's TDP values were expected to cover boost clocks and AVX as well, it's only 8700K/9900K/etc where Intel started to play fast and loose with their TDP figures. Which was after the introduction of Ryzen and the "PPT" terminology... in those days AMD pulled more than Intel's chips and they needed a way to hide it. Then they took the lead on efficiency.
kinda like TSMC naming their chips "7nm" and that resulting in huge mindshare problems for Intel even though 10ESF/Intel 7 (third-gen 10nm) was actually better than N7. Or Samung 8nm not even being as good as first-gen Intel 10nm, lol. So Intel had to rename their nodes too. A few bad actors ruin it for everyone.
88W is the number that matters for your load power measurement comparison - again, unless you disable boost.
The "X" chips are also clocked higher... 7950X would be 170W with boost disabled and runs 220W at stock.
