The passage around this formula
…its slower, generic-DRAM-rate branch. If context lengths and batch sizes instead grow faster than compression techniques can shrink the other factors — which is plausible, since agentic and long-horizon workloads push S upward directly — then the uncompressed cache stays the dominant bandwidth consumer, and the case for both faster HBM and for CXL-pooled or near-memory capacity strengthens correspondingly. Which branch the field is actually on by the early 2030s is not yet settled by public evidence, which is…
