True, but the A10 is much cheaper than any Intel CPU, so Apple could develop a multi-socket ARM motherboard to increase the number of ARM cores, to make performance compatible with Intel's (perhaps at lower cost, since Apple can get cheap A11s using the high volume of iPhone 8/X). Also, according to Geekbench, the single-thread performance of the 2.4 GHz A11 is 70%[1] of the 3.7 GHz i7-8700K. I'm guessing Apple could bring the A11 even closer to the i7 by increasing the clock frequency, which may not make sense for mobile devices (because of disproportionally higher power consumption). So, again according to the Geekbench figures, four A11s (at mobile clock frequency) is 50% faster than a 6-core i7-8700K[1].
