Good thing Apple is moving to M1; no more of that Intel crap. and stick with AMD for Linux.

I wonder what interesting things are in Apple's completely undocumented chips? There is that famous saying about known unknowns and unknown unknowns...

No more or less so than intel or amd. Or is the problem that the entire implementation is not public? Because even risc5 doesn't require that.

That isn't true. AMD aren't great at it, but Intel publish thousands and thousands of pages of manuals. They don't have the secret sauce in them as per se but Apple literally will not publish jack shit about anything inside M1.

There's also the "unpublished" stuff that occasionally leaks here and there; not something which I suspect will ever happen with Apple, but you never know...

Untrue. There're more documentation on Intel's CPU than Apple provide on an entire M1 laptop.

.. you mean the ARM specifications?

Out of the frying pan into the fire.

do you think the M1 doesn't have security bugs?

Apple's M1 too supports Spectre.

Note that the code will likely require minor modifications to apply to other CPUs or browser versions; however, in our tests the attack was successful on several other processors, including the Apple M1 ARM CPU, without any major changes.
