> Memory access times have not significantly improved in many years. We could say that it actually became worse and not better if we put it more into the context. For example, 90ns latency coupled with a 3GHz core is "better" than 90ns latency coupled with a 5GHz core. In latter, CPU core ends up being stalled for 450 cycles while in the former case almost half as much - 237 cycles. |
