Is 5.0 GHz not enough for you on a laptop? Well, how about 5.27 GHz? That is apparently what the Core i9-10980HK can operate at, the Comet Lake-H successor to the Core i9-9980HK. The clock speed boost allows the Core i9-10980HK to achieve a multi-core score over 32,000 in Geekbench, eclipsing even something like the AMD Ryzen Threadripper 2970WX.
