There are still a good amount of mobos that will default to lock the CPU down to 95W and won't even allow for small boost periods above 95w,a lot of review sites even made whole benchmark runs with such settings were you can see the 9700 be faster than the 9900 in single threaded stuff because the same TDP gets shared to less threads.
Stock settings can exceed base clocks so you will draw more power,if your cooling can only sustain 95w it will drop to base clocks,that's not thermal throttling these are the specs,you get what you pay cool for.
Also both turbo and PBO have the same basic idea,if you have saved up some power cache because you were idle for a while exceed your TDP by as much as temps allow for as long as they allow to get stuff done as fast as possible,after that TDP levels off.
Of course since ZEN is hitting it's limits much sooner and has almost no overclock headroom its boost and sustained numbers are almost the same,intel drops from almost 200 down to 150.
Which is still plenty above TDP but again is only a suggestion of cooling to sustain base clocks.
