38 TH/s miner... I'm skeptical. With all due respect, here's some reasons why:
Case sizeThe current state of the art Bitcoin ASICs use 28nm lithography. The latest 4th Generation Intel® Core™ i7 Processors use 22nm lithography (e.g. the
Intel® Core™ i7-4960HQ Processor). Intel is a big company, I doubt we'll see relatively small (compared to Intel) Bitcoin ASIC manufacturers using better than 22nm lithography any time soon. Even if a Bitcoin ASIC manufacturer did use 22nm, it is not a huge leap from the 28nm process used by Bitcoin ASICs now. It's a leap, but I suspect not enough to pack 38 TH/s into one miner in a desktop or 4U (say) rack-mountable case.
Power UsageAnd what about power usage? AFAIK current state of the art is Bitmine.ch in Low Power mode (pre-order, so we haven't seen a working example yet). Their website claims 0.35W/GH/s in low power mode. At that rate, 38 TH/s would draw 13.3kW. In New Zealand, you can pull a maximum of 2.4kW from a standard 10A household power plug. An entire house in NZ has a total supply of 240V @ 60A = 14.4kW. (Someone else can advise the figures for the US and other countries, but I suspect it is fairly similar). I'm pretty sure all the ASIC miners designed so far keep the power draw <= 2kW, otherwise it is difficult for a home user to use it. Perhaps the 38 TH/s miner is for datacentres only?

BTW, the
Asic Bitcoin Mining hardware comparison page on your web site is out of date. It looks like an old list published on another site I saw a while back. I don't have the time or patience to go through all the updates, but here's a few for you, free of charge:
- Remove TerraHash from the list - their business has closed.
- Include the 28nm miner pre-sales from Bitmine.ch - CoinCraft Desk and CoinCraft Rig.
- KnCMiner - remove Mercury, it is no longer offered. Update the specs on Saturn to 275 GH/s and Jupiter to 550 GH/s as per the KnCMiner website. My Jupiter gets 530+ GH/s, but some people get better than 550 GH/s, it varies a bit from unit to unit. Also the KnCMiner ASICS draw roughly 1.2W/GH/s measured at the wall (sample of 1, my Jupiter)
