So an i3-8100 has a single score of 1000, and the highest PC score they have is 1371? These Geekbench comparisons keep showing phone CPUs being faster than server ones, but I question their validity.

Here's an iMac (i9 9900K) result of 1402: https://browser.geekbench.com/v5/cpu/172942 https://browser.geekbench.com/v5/cpu/172942

The A12 has better single-threaded SPECint2006 scores than EPYC7742 almost across the board. It's about 10% worse than the 3900X, and 20% worse than the i9-9900K, so if the 20% uplift holds true for SPECint scores then the A13 should be pretty much par with the i9-9900K. ikr https://www.anandtech.com/show/13392/the-iphone-xs-xs-max-review-unveiling-the-silicon-secrets/4 https://www.anandtech.com/show/13392/the-iphone-xs-xs-max-re... https://www.anandtech.com/show/14694/amd-rome-epyc-2nd-gen/9 https://www.anandtech.com/show/14694/amd-rome-epyc-2nd-gen/9 https://www.anandtech.com/show/14664/testing-intel-ice-lake-10nm/4 https://www.anandtech.com/show/14664/testing-intel-ice-lake-...

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.
