I'd consider it feasible-- in my testing, my iPhone XS outperforms my mid-2017 MacBook Pro (with i7-7820HQ [1]) in single-core benchmarking with Geekbench 4. Not by much, but it does manage a slight lead: https://browser.geekbench.com/v4/cpu/compare/10006209?baseline=3218259 https://browser.geekbench.com/v4/cpu/compare/10006209?baseli... Granted, this probably wouldn't hold up for a more sustained workload since the fanless iPhone's going to hit its thermal limits much more quickly than the full-size laptop, but it's pretty impressive that they're edging this close to Intel anyways (in a much smaller, much lower-power package). It'll be really interesting to see what happens with the more unconstrained A12X that'll likely go into the iPad Pro this year.

Did you run it on MacBook when it was on battery? Might not get to the max TDP in that case. So it would be like 30W vs 4W, but it's also 14nm vs 7nm. Anyway though, it's still _very_ impressive from Apple, but much more believable. Looks like they've got very good engineers working on it. I hope they can scale it to the laptop requirements.

  I think that one was run on AC, but it was a while back so I can't be 100% sure. I keep meaning to re-run it to make sure, but haven't gotten to it yet. I also have benchmarks of Haswell-era hardware which the XS is also very competitive against-- including my personal desktop, which the XS beats in single-core and matches for multi-core. But that one's probably not an entirely fair comparison, given that it's older hardware and the machine wasn't intended to be particularly high-end when I built it. I'd like to see some more comprehensive benchmarking against Intel... I'd be inclined to do some myself, but I don't have a good benchmarking suite that isn't Geekbench. If only the SPEC benchmarks weren't so stinking expensive...
