Why? Remember that we're talking about single-thread performance. There's no big reason why servers should be more optimised for single-thread performance than mobile ones. It's more useful to use the extra die area for more cores, or other features. They have the same fundamental limitations that makes it hard to scale to higher single-thread performance (remember that CPU processors also have to minimise power consumption, even if they use a lot more power in total). They're both using cutting edge processes, and they both have more than enough die area to make a single core perform as well as is physically possible. I really do think this indicates that Apple/ARM has caught up to Intel when it comes to architecture and we already know TSMC has surpassed them in process technology.
