But now they are locking down their software hard. So there is really no free lunch.

In what respect is Apple “locking down their software hard” with respect to these new Macs?

Locked bootloader only booting stuff signed by Apple.

So these CPUs can only be used to run MacOS, no Linux or other alternate open platforms.

It's not just outperforming the MacBook Pro. It's also blowing away the current 2020 top-end iMac, which has a 10-core Intel i9. And it's doing this while using more than an order of magnitude less power (10W vs. a TDP of 125W for that Intel part). That's stunning.

TSMC’s 5nm node is exceeding everyone’s expectations.

On the non-Apple side, it will be interesting what AMD does with the 5nm node.

Not exactly. You can check the clock speeds: https://browser.geekbench.com/v5/cpu/4620493.gb5 Up to 5050MHz is stock behavior for the 5950X and it's using standard DDR4 3200 memory.

Even if the Ryzen wins out, that would still be comparing a desktop CPU to a mobile one, using 105W vs 10W. It is incredible that we are making these comparisons. Apple outdid themselves.

There's going to be a AMD mobile version of the 5000 generation soon and when looking back at 4000 generation their single core (boost) performance is going to be virtually the same as the desktop variant.

Desktop CPUs differ from the mobile CPUs mainly in how much can they boost more/all cores.

very treatable form of cancer Nope, he pretty much died right on time in terms of median life expectancy for his form of cancer: https://pancreas.imedpub.com/prognostic-factors-in-patients-...

Nope, that study is about survival of patients with his form of cancer and hepatic metastases. As far as I'm aware the cancer in Jobs was detected long before hepatic metastases.

Sure, call it what you want. This is the beta product. It’ll be buggy. It won’t be full throttle. I’m excited for whatever is next.

This is the beta product. It’ll be buggy. Doubtful. You know they've been using ARM-based Macs with the requisite version of macOS for at least a year inside of Apple. They've done a processor transition two other times; unlike the last two times, this time Apple controls the entire stack, which wasn't the case going from 68K to PowerPC or from PowerPC to Intel. Apple has been designing their own processors for a dec…

Even if it's used internally it doesn't mean it's not beta/buggy. Intel releases regular microcode patches and has issues with all their existing experience. This is apple's v1 which was in the pipeline for over a year. The designers are likely months into working on v2 already - that cycle is very long.

"Don't upgrade MacOS to x.0 version" is already a common idea. Why would it be any different for their hardware?

it's probably iPad pro - the current 2020 gen iPad pro has A12Z (essentially the same chip as 2018 A12X with extra GPU cores) - significantly older chip than A14. I think there will be an A14 iPad Pro refresh with mini led display in early 2021.

Laptop Macs of late are known for heavy throttling due to inadequate cooling, which cannot have been unnoticed in simulations

I have the 16” MacBook Pro. It doesn’t throttle and will happily run at max boost for tens of minutes.

Mine doesn't throttle when the ambient temperature is below 21°C, but throttles almost immediately if the ambient temperature is above 24°C.
