Think of it like this, they sell an accelerator card, people go “hey, this apple GPU is awesome”. then apple tells them it works even better in their own computers, because it does, and people go “I guess I should buy an apple computer, I can run my video editing software even faster.”

And then you have people both. Buying your accelerators, and entire systems. Now the ecosystem caters to a wide variety of users, not just “Pros, and facebook scrollers”.

Now apple would have to directly compete with AMD, Nvidia, and Intel. But this competition should potentially help drive innovation, which would help rapidly accelerate the growth and development of computer technology in a 4 way arms race.

They do have their afterburner card, and the Mac Pro already uses a modified version of PCIe. The key difference is the M1 macs are laptops and all in ones, and the Mac Pro is a modular system. It’s a different beast. The MacBook Pro has to be power efficient as well as fast, where a desktop computer like the Mac Pro does not have that limitation. The current Mac Pro already uses infinity fabric bridges to link the graphics cards. Apple could easily design an accelerator card that has everything you need in one card. A GPGPU isn’t hard to design. You just have to understand form factors.

The 192 GB refers to memory, aka RAM, not storage. RAM stands for Random Access Memory, which is used for holding data for running applications and is randomly accessible, meaning the CPU can access data from any address in memory. Large amounts of RAM like this may be used for rendering 3d environments, editing high resolution footage, or other intensive applications. For reference, your xbox has 12 GB of RAM, and my mid-tier PC has 16 GB of RAM, so 192 is quite a lot. Also this is a desktop computer, not a laptop.

I'm not sure it'd work out. A lot of what makes M1 work is having everything on the same fabric. It gives them awesome memory bandwidth, unity memory so the gpu properly shares the cpu's ram, giving zero transfer time, etc. A lot of the gains come from architecture that wouldn't survive being taken off the SoC package.

That said, I'd love to be proven wrong, because competition is good.

(On the down side, it's also why we're unlikely going to see replaceable RAM - taking it off the chiplets would take it off the fabric, and lose that bandwidth. Best-case scenario is the on-package RAM and the replaceable RAM would work on different tiers, making the on-package RAM the mother of all caches.)
