"Clock speeds will only double, triple in next 10-14 years"

He said that it’s clear that there’s a requirement for smaller products with longer battery life, and Moore’s Law is changing in a fundamental way. He said: "We’re reaching scaling limits at both speeds of transistors and the density of transistors".

System power cooling capacity is moving less quickly and there’s an order of magnitude factor emerging. This is even more striking, he said, when you compare the increase in theoretical clock frequencies over the next 10 or 14 years and the constraints of power means we’ll see only doubling or tripling clock frequency in the next 10 to 14 years.
