Why, M1?

In this video I’m going to tell you exactly why Apple’s brand new M1 chipset is just kicking the ever-loving silicon out of Intel right now, kicking them right out of the low power, entry-level Macs and, in some cases, posting results that just clown even higher power, higher-end PCs.

Why? Because of Apple's heavy investment in integrated, scalable architecture. That's what lets them cover all these products efficiently, without the complexity that would come from having to treat each one as a separate client.

And it also means M1 gets to leverage many of the same latest, greatest IP blocks as A14. Only the implementation differs.

For example, the compute engines are close to what a theoretical A14X would look like, 4 high-efficiency CPU cores, 4 high-performance CPU cores, 8 GPU cores, and twice the memory bandwidth and higher memory

But the M1 CPUs can be clocked higher and it has more memory. iOS hasn’t gone beyond 6GB in the iPad Pro or latest iPhone Pros. But the M1 supports up to 16GB.

Then there are the Mac-specific IP. Things like hypervisor acceleration for virtualization, new texture formats in GPU for Mac-specific application types, display engine support for the 6K Pro Display XDR, and the Thunderbolt controllers which lead out to the re-timers. In other words, things the iPhone or iPad don’t need… or currently just don’t have.

It also means that the T2 co-processor is gone now, because that was always really just a version of the Apple A10 chipset handling all the things Intel just wasn’t as good at. Literally a short series of chips Apple had to make, and run BridgeOS on — a variant of watchOS — just to handle everything Intel couldn’t.

And all of that is now integrated into the M1. And the M1 has the latest generation of all those IP, from the Secure Enclave to the accelerator and controller blocks, and on and on. The scalable architecture means it’ll almost certainly stay that way as well, with all the chipsets benefitting from the advances and investments in any of the chipsets.
