Voltage scaling stalled and frequency scaling hit thermal limits. Simply adding cores no longer restored historical performance curves. Meanwhile, last-level caches and register files grew so large that they began consuming energy comparable to—and often exceeding—the cores they served. Modern memory hierarchies evolved not independently, but in symbiosis with speculative execution. They became the scaffolding required to sustain large volumes of in-flight, uncertain work. Speculation optimizes for the appearance of forward progress. The memory system exists to sustain that appearance—and to clean up when predictions fail.
