The same thing happens on a lot of mobile devices as well. It's the reason that mobile devices generally don't get advertised with clock speeds. E.g., see: https://dl.acm.org/doi/abs/10.1145/3032970.3032982 https://dl.acm.org/doi/abs/10.1145/3032970.3032982 Unlike desktops, where CPUs from different quality bins are sold at different price points (with different clock speeds), mobile CPUs are simply run at different voltages to compensate for quality differences. The resulting differences in power dissipation end up creating different temperature profiles, depending on which bin you happen to get.
