With the usual ~70 Day turn-around for Chips that puts you a little past mid January for your first silicone.
the usual 70 day turn-around is for people who don't pay extra to the fab to expedite the process
Turn around is commonly closer to 60 days, and we are expediting the process in several different ways. Ever since mock tape out we have been streamlining every piece of the manufacturing process so that we can deliver at break neck speed as soon as we receive chips.
your quote is wrong:
"In Bitcoin mining hardware, the factors that matter the most are the speed of hashing and the consumption of power. The CoinTerra GoldStrike1 based TerraMiner series is poised to be the leanest and most powerful Bitcoin mining line in the market"the most important is speed to market & hashing... power usage is such a small % that if you are happy to shave 50% of power costs (tiny part of equation) and give up 75% of btc production (very large part of equation) you are terrible at math or just 'selling your book' as they say
if diff hardly grew, then yes you can show gains from less power but that is madness in this reality
