Well, AMD's Renoir 4C/4T Ryzen 3 4300U has a base frequency of 2700Mhz at 15W. If they felt like playing in the 28W space directly, one would think they might be able to have a fairly compelling product with either way higher base clocks or many more cores/threads at a similar power level. So calling Coffee Lake best in class might not be the best description any more.
