yes, I was thinking of HSA, but they don't seem to be working on it. I think it turned out to be hard, and therefore expensive, and they got distracted by staying alive by developing decent processors.

I think we could argue that tensorflow and/or pytorch has displaced any HSA interest, too. These are programming interfaces that do an OK job of abstracting from the hardware details, and are totally embraced by the most demanding field (AI).

They have abandoned it at their lowest to focus on Zen. Now they seem to start picking up the slack. Upcoming Instinct MI300 APU brings HBM as unified system memory, together with hardware cache coherency between CPU cores and GPUs within and across NUMA nodes.
