Hardware, Embedded Systems The CPU industy is working on 16nm chips to debut by around 2013, but how much smaller can it go? According to the smart guys, not much smaller, stating that at 11nm they hit a problem relating to a 'quanting tunneling' phenomena. So what's next? Yes, they can still add core after core, but this might reach a plato by around 2020. AMD's CTO predicts the 'core wars' will subside by 2020 (there seems to be life left in adding cores as Intel demonstrated a few days ago, the feasibility of a 1000 core processor.) A Silicon.com feature discusses some potential technologies that can enhance or supersede silicon.

From what I gather, it seems electrons for instance can always pass through any barrier as the probability is always non-zero, interesting...

Also seems tunnelling only seems to effect barriers 3nm or less (other than the odd electron that might get through (in theory))...

I guess we will have leaky CPU's soon enough if we don't come up with something else (which I'm sure we will).

I remember reading in BYTE magazine years ago that the maximum speed of a CD would be 10x. I remember thinking then how fast that would be...
