Well if what they saying is true that it power consumption is 10 times less than what exist now, if you assume 15 watts per core for standard hardware, then this thing 1.5 watts per core. so under 200 watts total at full load. $2000 for that cpu is probably about in the right ballpark. they said the cost is 3x lower than other things.
Okay, so if it's 200W, it's only 1/3 less than what I used, so it doesn't change the result much.

You can get a Compac F [1] for around $200 and 15W of power draw that pushes 300GH/s, so two of those would match this hypothetical CPU at a price of $400 and 30W. That's 5 times cheaper and at least 10 times more power efficient, so you could say 50 times better.
the problem with doing that is, it can't mine anything else except sha-256 coins and even at 300GH/s I don't think it makes any money.
Sure, you would buy more of them if you have $2000 in budget or just get something with better hash / $ ratio like an S17 ASIC. These are definitely overpriced if you want to get a lot of hashrate and really make some money. Even the little Apollo BTC has a better hash / $ ratio than the Compac, though it consumes more power (per hash).

which is why i later said that the only way this cpu could make sense in mining is to mine some other algo. where it could probably make some money.

but there is an upfront cost kind of like there is for asic mining. no getting around that. but i realize now that asics are way more advanced in bitcoin for cpus to be competitive. Grin
Sure, there always is. The CPU you mentioned will surely be great for something like Monero or other CPU-targeted coins, however I'm not sure if there won't be ASICs for those eventually, too (or already exist but nobody knows about it). But this is another topic. Wink
