Sorry I'm not following the math there, whats the relation between 100ns and 10Mhz? Why is that the tipping point?

1 second = 1 billion nanoseconds and 1 Mhz = 1 million times a second, so if something takes 100ns you can only do it 10 millions times per second (10Mhz).

A 10Mhz processor has a clock cycle of 100ns (0.1 millionths of a second). Those are just rough representative numbers I picked...any particular RAM delays would be different and the actual latency would be complicated by bus speeds and protocols etc.

Thanks for the explanations that math makes sense to me now. Cheers.
