The problem is not understood by the prime majority: As said above, the performance, and power consumption of modern CPUs is an "all, or nothing" choice. Modern laptop CPUs are nothing, but well disguised desktop/server cores. Nobody designs designated mobile use cores, unless you are in ARM world. In principle, they are unable to work in the "middle gear." CPU makers tried to make them to, but never managed to get a reasonable trade off. So you cannot run them reasonably at "half-performance"
