> The basic GCN microarchitecture underpinned every single one of AMD’s compute accelerators for nearly 15 years [...]. With CDNA5 AMD has moved over to a microarchitecture that is based on the RDNA series putting a bookend to the long-lived line that was the GCN microarchitecture.

So everything is new again. Will this be another "buy now, have ROCM work in 3 maybe years if you are lucky"?

Arguably this might reduce it, because now ROCm won't be prioritised for the GCN-based systems?

432 GB of RAM per chip. Tens of terabytes per rack. Clients queuing up to buy them.

RAM prices are not coming down any time soon.

Of course. Wishful thinking is a true staple of human intelligence.
