Fifty or Sixty Years of Processor Development for This?

Energy efficiency is important (in a server/bitminer and in mobile), but do you have figures for (1) performance; (2) cost?

Custom asics would be expensive now, but perhaps... exponential... cost decrease with sufficient demand. A related approach is programmable asics. I've heard this was researched decades ago, but (I presume), silicon was so cheap, so to speak, it wasn't worth it then.

Today, with "peak silicon", perhaps all these discarded tailings will be picked over. To mix mining metaphors.

The only relevant figures I know of are from mining bitcoin. [0].

What do you mean, if not fpgas?

thanks.

wait, we're looking at 18,000,000 Mhash/s vs 2568 Mhash/s Like... 4 orders of magnitude?

And, 11,000 Mhash/J vs 3 Mhash/J, over 3 ordera of mag, just like you said.

yah, fpgas
