Probably not but I think the point stands that latency hasn't made any major strides since the switch from SDR to DDR.

That's very interesting. The estimate of 100ns came from here: https://people.eecs.berkeley.edu/~rcs/research/interactive_l.... and is probably not very precise (maybe because it is only capturing rough order of magnitude). I have now updated the post. Thanks for the feedback! Specific constant aside, the point about latency not improving much still holds.

There are these things called speed of light and virtual memory. The latency of the physical RAM is completely irrelevant unless its embedded directly on the cpu
