March 2014 Mining Devices

[BigLad]

KnC are bringing out new devices in March.  Anyone have any info on these devices, please state your source or if that its just your own thoughts?

Being that Terrahash is planning the 2TH/s miner for Dec, I think a 5TH/s or 10TH/s could be entirely plausible, but at the current difficulty increases wouldn't be worth it?

A 20TH/s would start returning a nice chunk of change. - http://mining.thegenesisblock.com/a/2cd59d2121

Why not for the fun of it a 50TH/s costing $30000 - http://mining.thegenesisblock.com/a/a8c73298ac

What are your thoughts for next years miners?

They're going to hit the wall of diminishing returns on node sizes fairly soon.

Once the miners are on 28nm, they are at the limit of current tech (unless you're Intel, who will not even bother with bitcoin).  The returns on shrinking feature size have been smaller and smaller with each shrink lately, and this is likely to continue.

At this point, the only real optimizations are in layout, but there are only so many creative ways to improve incrementing a nonce, performing a SHA256 block operation or two, and comparing the result for a number of null bits.

I expect everyone to eventually settle into around the same price/performance/power consumption, though the companies getting to 28nm first will obviously have an advantage.
