Is that true even with a chiplet or north bridge approach? I feel like we’ve seen plenty of examples of CPUs laid out this way. Yeah with a performance penalty

Is that true even with a chiplet or north bridge approach? I feel like we’ve seen plenty of examples of CPUs laid out this way. Yeah with a performance penalty but that 192GB of L4 with direct GPU access would go a long way to making that better.
- brucethemoose2 3y agoApple could indeed fab a small memory controller chip, but I am not sure the M2 Ultra die has the interconnect to support such a thing? AMD makes this looks "easy," but it is not easy, and they built for Infinity Fabric from the start. As said below, the answer is CXL. Apple would be stupid not to support CXL devices on the M3 or M4, though I would not be surprised if they skip it
- arcticbull 3y agoI actually wasn't familiar with CXL, I'll check it out. Thanks!
