And it turns out that the F3 shown in that video is apparently NOT an ETH ASIC miner.
Bitmain released their E3 today for preorders - delivery NOT 'TILL MID JULY (indicating that they do NOT have many units on hand).
180 Mhash
800 watts
(they CLAIM these are minimums, but they'd have to do a TON better to change the below commentary).
About the same hashate and same power draw as a well-tuned 6-card RX 480/580 "BIOS modded for memory straps" rig.
Slightly LESS hashrate and slightly MORE power draw than a well-tuned 6-card GTX 1070 rig.
NOT exactly a GPU mining killer.
Note that they would have to sell well over ONE MILLION of these units to achieve 50% of the current ETH network hashrate.
For perspective, current Bitcoin network hashrate equates out pretty closely to 2 Million S9 units (but PART of that hashware is LW.COM internal-usage miners, some is Avalon 721/741 units, some is EBang miners, et cetera - Bitmain PROBABLY has sold a total of ONE MILLION S9 units but it took them almost 2 YEARS to manage that despite having THE best performance miner on the market).
The E3 is NOT a GPU mining killer - in fact, I doubt it's going to make much more than a SMALL DENT in ethash mining profitability before ETH goes Proof of Stake and the REAL shakeout happens.
On the positive side, they DID get the price at $800 to a reasonable level, and probably WILL sell as many of these units as they choose to make since that's a LOT cheaper than building a GPU rig that can match the performance.
