I'd expect a huge performance jump when the new ARM-based Macs come out, both in Single-core (they can ramp up the clocks and increase cache and execution units) and Multi-core (they can add more cores to fit new power budgets as well). The current A11 chips for iPhones are within 10% of Intel's top mobile chips on Geekbench, and within about 30% on their top desktop CPUs. It's entirely possible for chip architectures to see 2x-3x speeds when moving from mobile power budgets to desktop power budgets. An Intel Pentium 4410Y Kaby Lake running at 4.5-6 Watts gets about 1800 single-core on Geekbench, while an Intel Core i7-7700K Kaby Lake running at 115 Watts gets 5600 single-core on Geekbench.

> The current A11 chips for iPhones are within 10% of Intel's top mobile chips on Geekbench No, they aren't. iPhone X's multithreaded geekbench score is 10k. The 15" macbook pro is 15k. That's a lot more than 10%. It's only close if you look at the lower end Intel chips, the dual core ones (which is what Apple ships in the 13" macbook pro).

  Those are multi-core numbers, not the single-core numbers. What do you think is the most important for 250million desktop users? Because the vast majority of them are sitting idle waiting for interaction tasks, like on your system now.

    > Because the vast majority of them are sitting idle waiting for interaction tasks, like on your system now. My dual Xeon E5-2690 v4 regularly loads all its cores and benefits greatly from them, but keep making assumptions by all means. But if all you want is a chromebook competitor then sure, A11-class works fine. I'm going to guess that the people using Mac Pros tend to care a bit more about just running Chrome/Safari, though. Maybe Apple is just going to completely give up on their historically strong content creation market.

    Even browsers are doing a better job of loading multiple cores now and desktop machines often have more processes running in the background.

Geekbench is not representative of application performance, sadly.
