The old chip pulled 33% less than its rated TDP in the real world.

Also, lol if you actually think TDP means anything anymore. Over the last 5 years it's become a marketing number more than anything else. It gives you a vague category of what power consumption will look like... at base clocks, under a non-AVX workload. Modern processors will happily blast past their TDP by 50-100% if there is thermal headroom available.

(And that's where laptops come up short - they can't actually cool a steady-state load, so these laptops will happily turbo themselves into a wall, and then once the heatsink is saturated they'll thermally throttle. Looks great in a 30-second benchmark though!)
