>I gather in the early days the LPDDR used on laptops was slower too Oddly, the latency hasn't improved too much - CAS is often 5-10ns for DDR2/3/4/5. Bus width, transfers per second, queueing, power per bit transfered and stored have, but if a program depends on something that's not in cache and was poorly predicted, the RAM latency is the issue. |
