Future Trends

Transistors are still being made smaller and smaller.

We have hit the Power Wall resulting in a Dark Silicon approach. We can no longer turn on all of the chip and get the heat out cheaply: perhaps one tenth maximum for today's 22 nanometer chips. Even less in the future.

Water cooling remains an option to mitigate the Power Wall. »Insights Article

Slow, bulky power transistors will turn thousands of power islands on and off under automated or manual control.

Conservation cores: use of high-level synthesis (HLS) of standard software kernels into application-specific hardware coprocessors and putting them on the chip in case they are needed? Afterall, they have negligable cost if not turned on. »Venkatesh
