HBM

Memory-chip pressure is becoming an AI bottleneck in its own right

The AI chip story is often told through GPUs, but memory is becoming just as strategic. High-bandwidth memory sits close to the accelerator and determines how much useful work expensive chips can actually do.

Why it matters: Anyone tracking AI infrastructure should watch HBM like a core input, not a supporting component. The next compute bottleneck may come from the parts that make the headline chips useful.
