HBM is very expensive though. I wonder if older generations are still being produced, but significantly cheaper these days? A P100 from 2016 (HBM2) has 732 GB

A P100 from 2016 (HBM2) has 732 GB/s memory bandwidth [1], whereas the ddr-4 [2] produces 50GB/s. So the AMD APU would be more than 10x slower at LLM inference.
Edit, even old GDDR5 cards like the P40 have bandwidth of 347GB/s. [3]
