It isn't so much about the benchmark one uses. A CPU converts electricity to heat, and does computation as a side-effect. A CPU embedded in a laptop (or moreover, a desktop) is going to be able to convert more electricity into more heat — and more computation — by virtue of being able to better dissipate the heat due to having a larger surface area to do it over. (In addition to having active cooling — vents and fans — which I've yet to see on a phone.) Modern non-phone CPUs can have TDPs of more than 80W. If your phone did 80W, it would burn your hand. So, forgive me if I'm skeptical of any benchmark that says a phone outperforms a laptop. You're arguing that the phone CPU can get significantly better performance, do so with less power, and occupy a form factor smaller than what a laptop requires? Why would I not just manufacture a less space-constrained version of this chip (to make it cheaper) and stick it in a laptop? I Googled the specific benchmark you referenced. I'm not able to find results on it, but one of the top hits was this: https://arstechnica.com/information-technology/2017/04/googl... |
