It really depends on the tdp. On my laptop which has a 2070 with up to 115 w and an 10th gen i7 with up to 45 w the cpu can go up to 95 deg and the gpu throttles at 86 deg.
Some laptops have Max q or low pwer versions of the same card which have a lower tdp and produce less heat. But for higher power gpus and CPUs they will most certainly go above 80.
