HBM is designed to feed GPUs with enormous amounts of data, reaching bandwidth in the terabytes-per-second range. That's why NVIDIA's AI systems and AMD's Instinct accelerators rely on HBM. Optane Persistent Memory was much slower. Real measurements found read latency around 374 ns and bandwidth around 38 GB/s for reads, which is probably why Optane is dead.
