While i dont like apple, moving away from X86 is the right thing to do. ( moving away from ppc was a mistake )

I have not heard this about the M2.

Sun Jul 31 2022 12:33:05 PM EDT from reb0

The low spec M2 is worse than the low spec M1. Is it coincidence that the PPC G5 was worse than the G4? I think they should've went with AMD like all the major PCs went since AMD is cheaper than Intel. And not to mention, AMD has a higher performance still. But, it might be a while until AMD gets their chips working good on laptops though...

True.

Is there a high spec M2 and how does it compare to an AMD?  I thought the reason Apple changed to a different CPU again was because they didn't want to be impacted by a third party manufacturer.

Apple is unique in that they can get away with doing changes like this at all.

Id say it was more about total control than being impacted. Apple is a bunch of power hungry elitist f-ers.  

But ya, id imagine they have more than one level of chip. "M2 pro", or some such stupidly named thing.

I guess in a "fabless" world it's less of a big deal than it used to be. They basically just bought a bunch of IP from other companies and threw it together in a configuration that they felt was ideal for the computers they wanted to build.

Pretty much.  There are not many left really making chips.

The idea of the semiconductor industry dividing up into designers and manufacturers sounds efficient to me, and like it would make more sense from a business point of view. I guess we will see what happens. Intel is one of the few left that still insists on being both. (Eventually PD will read this and enlighten us with some more Intel-insider stories.)

I think there are advantages to both models. 

When i worked for GM we made our own chips  You are not reliant on anyone else..

He will tell us that Intel is a manufacturing company, not a chip company.

I thought his latest observation was that Intel is a government contractor.
He'll clarify next time he's here I guess.

Hmm so Apple announced they are starting to move away from ARM and towards RISC-V.  First in support components on their SOCs, but later it will be 100% even if they didnt admit it yet.  Wont be tomorow as it takes time, but i bet in 5 years we see one that ditches ARM totally

That didnt take long to make that decision. Figured they would, they get total control then. No license fees, no rules, so they can lock it down as much as they want. Good luck getting drivers, or even running non-approved code.

NVIDIA is next. they already have RISC-V in their GPUs a 'glue'.  And after losing the fight to buy ARM, you know that is where they will go as well.

It is possible that they've hit the peak of what ARM is capable of doing.
Who knows. We do know that the MAC OS can move between different ISAs easily because of the Rosetta translator and Universal Binaries. They seem to have that covered pretty well, actually. Rosetta gets used for a little while but the big software houses all seem to add the new ISA to their universal binaries pretty quickly.

Does apple have a bytecode format they like to use? Something like the Dalvik VM on Android? That's usually the tactic that gets employed when you expect to have computers running a zillion different processors.

I think they're quite opposed to bytecode. They've banned most third-party language interpreters (which might use bytecode) from Apple Store. You get JavaScript, that's about it...

Nah as there is even more powerful ARM in data centers already.

I think its purely cost and control.  They see the advantages.
