Alder Lake Core i9 processor is faster than the M1 Max

I still maintain the M1 Max Quadro is a figment of media imagination. The M1 Max die is designed for precisely two-die usage. Not four. The IRQ controller has registers for two dies. The drivers reference two dies. The whole thing screams two dies everywhere.

4-die Apple Silicon machines will surely come, but not with the M1 Max die. It'll be a new design.

What about a dual CPU Mac Pro?

Edit: thinking about this for a few more seconds, I realise this is a completely separate discussion, but I was just trying to think how Apple could accomplish the Quad branding even if internally its separate CPUs.

How would you connect the CPUs together then? There's no mechanism for that. You need a bus, IRQ routing, cache coherency, and more. Those features are there in the Max with the d2d interconnect, for up to exactly 2 dies.
