Memory latency went down mere 2x between SDR and DDR around 2000, and then stayed flat for the last 20 years: https://en.wikipedia.org/wiki/CAS_latency#Memory_

  > Memory latency The widening gap between memory latency vs speed of processing in the processor (and how that arguably makes access optinizations that used to make sense between processor and HDD sensible between processor and main memory) is the issue that was being discussed, so memory latency can't be counted as part of processor speed in that context.
