Have been following the different manufacturers in mining equipment. I just wonder how they can do this:
Consider:
Cointerra --- 28nm chips x 16, can only produce 100GHS per chip and machinewise 1600GHS, and use 1.3W/GHS
Antminer S3 --- 28nm chips x 32, can only produce ~15GHS per chip and machinewise ~450GHS, and use ~0.78W/GHS
Spondoolies --- 28nm chips x 30, can produce 200GHS per chip and machinewise 6000GHs???, and use <0.5W/GHS???
I know Cointerra is kinda crapy, but the "Cointerra vs Antminer" comparison makes sense, Cointerra use higher frequency per chip thus more GHS per chip, but less power efficient. vise versa. And indeed both these products exists, but both delivered under-spec, suggesting that the industry struggled in further pushing the 28nm chips to higher performance ... 28nm chip has more or less reached the limit (i.e. overclock setting: 100GHS with 1.3W/GHS, or underclock setting: 15GHS with 0.78W/GHS).
Now the "Cointerra vs Spondoolies" and "Antminer vs Spondoolies" comparisons doesn't make sense. Spon got both chipwise and powerwise more efficient than both Antminer and Cointerra ... that doesn't sound right ... has any of this product been shipped yet?
you do realize the 3 chips are all different?
also the s-3 should not be compared to either unit. the s-3 is a small unit in physical size . it can be scattered about your home. it can be under clocked. it is pretty quiet .. the coin terra gear and the sp30 are big pull a lot of power on 1 circuit . they are loud much better gear for use in a data center.
the s30 will not hash for you for at least 45 days. it should not be compared to anything at all.
the s30 is being built in a country that has been under missile attack for the last two weeks.
the s30 in hand mining today would beat everyone! but it is not in hand.
my s-3's are mining right now. they will be roi by some time in sept due to my lower power cost (only can run 2 this way)
I would have loved to purchase a s10 back in april went with a dragon miner. i just did a fiat roi with it this week.
