SummaryMicron's chart shows compute performance scaling roughly 3x every two years while HBM bandwidth grows under 2x, illustrating a widening gap between processing speed and memory throughput that constrains AI workloads.
Why it mattersQuantifies the memory-wall gap from a primary vendor, giving readers a concrete basis for reasoning about why LLM inference stays bandwidth-bound despite faster GPUs.
