> THERE IS ABSOLUTELY NO WAY THAT A 5W PART LIKE THE A14 IS FASTER THAN A 100W PART LIKE THE i9-10900k! I understand they are comparing single threaded speed. FWIW, the 100W i9-10900k isn't even Intel's fastest single-threaded chip: that's the i7-1165G7 (a 28W part). Intel's desktop stuff is ancient: they're effectively still just Skylake (2015) derivatives; for single-threaded stuff the more modern designs they're shipping on mobile (Ice Lake and later) beat the desktop parts because their IPC is that much faster. Power doesn't really help single-threaded performance, aside from wide vector units, nowadays.

Is it sustainably faster, or only for a few seconds until it throttles? Searching for "10900k vs i7-1165G7" showed the 10900k as mostly faster with a few exceptions. I'm curious about next week's launch and benchmarks, Apple's claims compare it to a 1.2GHz i7, which I expect to quickly throttle. That's why I also expect the parent comment to be right, current desktop CPUs will still be faster.

  You can see a single-thread benchmark for both of those here: https://www.cpubenchmark.net/singleThread.html https://www.cpubenchmark.net/singleThread.html (comparing desktop vs laptop tabs), they get a similar score. The perf vs power charts on that website also put to rest the mistake of thinking perf simply increases with watt consumption. As for performance vs heat, well, you'd expect even better results from the chip consuming much less power. How does that 100W chip perform with a phone-miniaturized heat sink? Or the power-sipping chip with a double-tower fan cooler?

    Agreed, I think you make different design decisions- a mobile CPU is not just an underclocked desktop CPU. Apple also introduced a new CPU, not just put a A14 inside. I'm looking forward to benchmarks and seeing how well the new machines work - compiling speed, lightroom, responsiveness, how well Chrome works with max 16GB RAM :).
