Absolutely this. I have a 16'' mbp and it constantly throttles, even when I manually set the fans to full blast and use a cooling pad. There's no way to sustain the 45 watt tdp for more than a few seconds.

Anecdotally, my outdated i5 quad core is much snappier than the mbp i7 8 core because it can go all out at 69 watts/max boost for hours and not throttle for a second.

Disable turbo boost. Throttling is not directly linked to any temperature sensor, and turbo boost almost instantly causes throttling, which then takes some time to return to normal because of a back-off algorithm.

I’ve used the software that lets you modify all the CPU flags and nothing helps. Killing turbo boost sucks, having a frequency in the 3.0Ghz+ instead of 4.4Ghz+ is brutal when you are single thread bound.

This is exactly it, the thermal ceiling leaves almost no room to use the full 45 watt TDP. The fact that this problem isn’t a huge PR nightmare shows just how “pro” the typical buyer’s workload is.
