    Well Synopsys has offered full 7nm DDR5 and LPDDR5 memory interface IP since october 2018, and Cadence does as well. So Joe 7nm garage SoC builder have been able to buy this off the shelf for half a year already. If AMD doesn’t support those memory types it’s by choice. Rather dubious choice IMHO given that they try to carve themselves a market niche by supplying CPUs with high core counts and APUs with theoretically high performance. They need the data flow to support that to really reap the benefits. Or rather, their customers do.

    Well I think the chiplet approach would let AMD do that, decoupling the memory controller from the CPU would let AMD all the space they need for it and improve it independently from the CPU design.

    We’ll see. I do believe that AMD would stand to gain a lot by being on the ball when it comes to the memory subsystem. Unfortunately, HBM hasn’t really materialised for PCs, but AMD may still be able to leverage their experience in the future.

    Personally, as a user of stationary PCs, I’m not in the market for a new system until the PS5 has been introduced, and gained some multiplatform software support at its native level (i.e. not cross-gen titles). I guess that will be late 2021 at the earliest, and by then DDR5 (and possibly PCI-5) is likely to have been on the market long enough to have stabilized. It would be nice to have some headroom CPU wise in order to facilitate higher framerates than the console targets, but that may turn out to be tricky.

    Then again AMD is likely to transition to TSMC 5nm around then, which seems like it could be a worthwhile lithographic step.
