We know (more or less) exactly what the Pro desktop chips will be, in the same way that these laptop chips weren't much of a surprise - they'll be basically exactly this, but bigger. More of it.

They can't get that much bigger. The Max is already over 400mm^2. For comparison, the biggest chips are around 600. Apple can't realistically get much bigger than this since yield already drops off a cliff at 600. Getting bigger than that will be tough for them since it isn't clear that apple has put R&D into interconnect tech needed to make effective multi-chip modules.

  They are probably going to do two M1 Max chips in the imac, so basically take the existing m1 max, and double it (at least for multicore perf, who knows how single-threaded will play out).

    They almost certainly will not do this and it would be a NUMA nightmare if they did.

      Not sure why you were downvoted for this. Considering that some of the magic in these things is the shared, local memory with a very wide bus it would seem obvious that trying to go multi chip would indeed be a massive headache in this regard

        That isn't what that article is saying.

  It looks like they were designed for chiplets from the start. So desktops could simply be the existing chips stacked.

    Is this true? I was curious and searched around for sources, but it looks like all of the news outlets screwed up and thought the M1 Pro was going to be a chiplet based device called the M1X. All of the M1 devices have been monolithic dies so far.
