> The M1 chip, which belongs to a MacBook Air with 8GB RAM, features a single-core score of 1687 and a multi-core score of 7433. According to the benchmark, the M1 has a 3.2GHz base frequency.

> The Mac mini with M1 chip that was benchmarked earned a single-core score of 1682 and a multi-core score of 7067.

> Update: There's also a benchmark for the 13-inch MacBook Pro with M1 chip and 16GB RAM that has a single-core score of 1714 and a multi-core score of 6802. Like the MacBook Air , it has a 3.2GHz base frequency.

So single core we have: Air 1687, Mini 1682, Pro 1714

And multi core we have: Air 7433, Mini 7067, Pro 6802

I’m not sure what to make of these scores, but it seems wrong that the Mini and Pro significantly underperform the Air in multi core. I find it hard to imagine this benchmark is going to be representative of actual usage given the way the products are positioned, which makes it hard to know how seriously to take the comparisons to other products too.

> When compared to existing devices, the M1 chip in the MacBook Air outperforms all iOS devices. For comparison's sake, the iPhone 12 Pro earned a single-core score of 1584 and a multi-core score of 3898, while the highest ranked iOS device on Geekbench's charts, the A14 iPad Air, earned a single-core score of 1585 and a multi-core score of 4647.

This seems a bit odd too - the A14 iPad Air outperforms all iPad Pro devices?

The results seem a little weird but if remotely true then these machines are going to sell like cup cakes.

Why would anyone (who is not forced) buy an Intel PC laptop when these are available and priced as competitive as they are?

Until all software is ported to ARM, it will run in emulation, which is going to be slower in most cases. People invested in plug-in ecosystems, like DAWs or video editing, will likely have an endless long tail of plug-ins that aren't getting ported, or that require a re-purchase to get an ARM version. And due to Rosetta's architecture, you can't mix ARM and x86 plug-ins (in-process, like VSTs - Apple wants you to use AUv3 which is out of process but nobody does that), so you will be running your entire workflow under emulation until you can make the switch hard and all at once. And some of your software will never make it.

Mark my words, this is going to be a massive shit show for people using those ecosystems, for 5 years if not 10. It already happened with the PPC transition.

won't emulation catch up in those timeframes ? still, 3+ yrs which is a long time...

Three years isn't that long for CPU performance gains anymore, but even if it was, it isn't the emulation that gets faster, it's the hardware. Contemporary ARM machines emulating x64 would still be slower than contemporary x64 machines natively executing x64.

You're also going to be in a bind if Apple decides they don't care about the long tail and stops supporting emulation before all of your plugins have been converted (if they ever are).

There is no emulation per se, there is a one time AOT translation of Intel to Arm. Then that native code just runs. So no emulator is running on the cpu while the app is.

There is an exception for apps with JIT and those will perform poorly (think Chrome and every Electron app).

"Emulation" is a catch-all term that includes binary translation, static and dynamic, which every modern emulator uses (Apple just doesn't want you to use that name because people think emulation is slow). Rosetta2 is not a pure static translator, because such a thing can't exist (see: self-modifying code).

Just because binary translation is used doesn't mean it's magically as fast as native code. Converting code that runs on architecture A to run on architecture B always has corner cases where things end up a lot slower by necessity.
