I have the 2016 version of the machine, base model, and it throttles. Not nearly as badly as anything else in it's thinness class, but the CPU can only run at 37w as measured by Power Gadget under p95 with fans forced to 6500rpm. PC manufacturers often throttle the CPU with the BIOS on purpose or set PL1/2 which Apple doesn't do. Similar PC notebooks tend to keep the CPU at 85C and run them at 15-20W. Apple runs the CPU at 102C before throttling them, and there aren't apparent power limits. They're trying pretty hard to solve this problem and to be honest there's not very much more they could be doing short of putting last-mm^3 heatsinks everywhere or making the fans even louder. I'm personally okay with the form factor they've chosen and they've done their best with that.
