Let me see if I can put some reality into this...
The unit with 40 chips, (5x boards), shows about 212GHs average per board running an undersized share/hash. So, If running with the appropriate diff-rate of 64, which that unit should be doing, I'll say it runs closer to the peaks I saw of just under 222GHs per board. Total, that is 5x 222GHs = 1110 Peak (Which is what a company advertises as a units "Ability" or "Potential". Not to mention that it takes about 30 min of mining to settle-in to a decent average, which is higher than start-up averages and peaks.)
The power consumed read as, 1059-1061 Watts, "from/at the wall". (Since power does not move "to the wall".)
They also admit that the "unit will run with lower wattage", once they actually optimize it. (Obviously, this is just a RAW setup, which has not been tuned, it was just made to function for the demo.) For now, lets assume they don't get any better, with 40 chips, running at an unspecified operating voltage. You don't know if those are slightly voltage-bumped, which I assume they are, by the specs of the units and chips.
The units being sold to us are 1.2THs units. (Still does not specify if that is a maximum potential, or normal operation potential, but I will assume "normal for the unit, at the stock settings of the unit". Also I will assume that is a peak potential for that mode. Eg, ideal cooling and power delivery of your home. Thus, potential. Individual use may vary, obviously.)
So this would require more than 40 chips, as 40 is only what is required for the 1.0 advertised units. With each card being roughly 200GHs (222GHs peak, at non-optimized settings.) This would be 6 cards, which is 48 chips.
6 cards (48 chips), running non-optimized deliver 222GHs peak (at an unspecified operating voltage). This is a total of 1,332GHs or 1.332THs peak, in normal mode. (Not Max, because that would be "turbo", and that is not how these are being setup.)
Voltages are variable, and settable by steps, so how AMT sets-up the voltage as "normal", will ultimately matter. However, I will assume, rightfully, that the video showed just the chips running at the "normal" chip-voltage.
Quick recap of the 5x units values...
Power-saver: 750GHs {est: 400W}
Normal-mode: 1000GHs {act: 1060W} (
1110GHs peak shown)
Turbo-mode: 1500GHs {est: 1875W}
Translate up to the 6x cards (48 chips) AMT's minimum possible chip requirement
Power-saver: 900GHs {est: 480W}
AMT-tuned: 1200GHs {est: 990W} [900W + 10%] <- voltage below "chips normal mode".Normal-mode: 1200GHs {act: 1272W} (
1332GHs peak shown)
Turbo-mode: 1800GHs {est: 2250W}
Now, provided AMT uses this Minimum possible chip design, and does not add more chips... (More chips would allow them to run at lower voltages, delivering more GHs per the same wattage.)
900W, the "estimated" power consumption, plus 10% = 990W (That is the "complete adjusted estimate".)
1200GHs, the "estimated" peak production ability, minus 10% = 1080GHs (That is the "complete adjusted estimate".)
By those estimates, the projected 6x (48 chips), would operate within specs, slightly below the "chips" "normal voltage". Which, for the AMT 1.2THs miner, would be the units "normal operating voltage", or "stock setting".
It would only take about 60 chips, operating at lower voltages (but not power-saver low), to produce the desired 1.2THs at 600W, but I am sure the 600W +10% (660W) is the consumption in power-saver mode, which should be about 900GHs. (480W estimated by the producers of the chip, for their completed units. Which would be about 600W if they used 60 chips, instead of 48, and produce 1.2THs, not 900GHs.)
So... If this is only the 48 chip design (6x boards), that allows me to push the unit to 1.8GHs potentially, by adding one more PSU. Nice... if it is 60 (doubt that), wow, that would be about 2.4GHs... Actually, that makes 60 chips sound like a more realistic design. (Still doubt I will get 60 chips though.
)
40 chips... Not... that is not the system they sold us, 40 chips is the 1.0GHs unit. That is why I would have never gotten the unit from coincraft, besides having to pay crazy VAT for delivery.
I don't see these units being impossible to fall into the specs. My view has not changed. The chips have exceeded the design specs themselves. So should most of the units.
Hope AMT is generous with the first production of non-optimized and heavily-populated boards. (Would like to know what the chip-count would be for the units still... Anything over 48 would be freaking great! But 48 would be plenty still. 1.8THs potential from a 1.2THs machine, and I am happy.)
