I did a comparison thread on www.bitcointalk.org
I'll re-post the main points here
I compared it to a KNC Titan 300mh/Innsilicon A4/ and the L3 BItmain Scrypt miners
They were ALL EXTREMELY CLOSE IN $$$$ MONTHLY AS PROFIT
Anyway below is a recap from the above bitcointalk thread
(hmmmm I guess I should have posted on here first) Anyway for those into this comparison chime in
I'm using www.litecoinpool.org/calc calculator from www.litecoinpool.org a free NO FEE LTC pool that pays at 103% fyi
ok cutting it down further
KNC Titan 300mh at 1200w (using latest mods and gen tarkin software and improved noctura 3000 rpm fan etc) at 10c kwh at 4.17 LTC getting 103% on litecoinpool
(again see above calc link).
KNC Titan 300mh
24 hours 2.01788086 LTC 8.41 USD 2.88 USD 5.53 USD
7 days 14.12516602 LTC 58.90 USD 20.16 USD 38.74 USD
30 days 60.53642578 LTC 252.44 USD 86.40 USD 166.04 USD
L3 Bitmain 250mh
What this L3 Bitmain Scrypt miner at 250mh and 400w making at 400 watts bet its really 500 watts but anyway at 10c kwh at 4.17 getting 103% on litecoinpool
24 hours 1.68156738 LTC 7.01 USD 0.96 USD 6.05 USD
7 days 11.77097168 LTC 49.08 USD 6.72 USD 42.36 USD
30 days 50.44702148 LTC 210.36 USD 28.80 USD 181.56 USD
hmm...diff is $15.52 a month difference in profit. LOL! (Not as bad as I thought)
I also think that IF they are off on the watts and it is really 500 watts they'd be more or less equivalent.
Also IF the L3 Bitmain 250mh a month unit is sold at $2000 lets say (could be as high as $2300 but lets be optimistic) and compare it to an A4 getting 260mh to say 170mh
(they say 280mh but they also say each cube on the 2 cube A4 is 135mh lol) So we will use 270mh a kick ass fixed A4 batch 3 with firmware fixes....
A4 Innsilicon 270mh at 1100 watts (so I've been told by folk running them...Innsilicon says 1000 watts ...lets use 1000 watts) (again using litecoinpool calculator for LTC at 103%)
24 hours 1.81609277 LTC 7.57 USD 2.40 USD 5.17 USD
7 days 12.71264941 LTC 53.01 USD 16.80 USD 36.21 USD
30 days 54.48278320 LTC 227.19 USD 72.00 USD 155.19 USD
So to sum up
KNC Titan 300mh at 1200watts using gen tarkin 3rd ware software with eff tweaks to get such, just to note at 10c kwh and $4.17 LTC you get MONTHLY $166.04 PROFIT
L3 Bitmain 250mh (say Jan 15th 2017) at 400 watts (they say likely to be 500 watts imho but lets use 400 watts) at 10c kwh and $4.17 LTC you get MONTHLY $181.56 PROFIT
A4 Innsilicoin 270mh (they say 280mh but know of none such) at 1000 watts (most say 1100 watts but using 1000 watts) at 10c kwh and $4.17 you get MONTHLY $155.19 PROFIT
hmm.....not to impressed...this only works also IF you got a unit Jan 15th 2017..I doubt they will get it to us in the USA at that time frame. Likely 1 month later.
So unless LTC and scrypt coins really, really pump here....this looks to me like oranges/oranges/oranges....on a side note....I see Titans sell for 2k/A4's are 2k with shipping and
L3's let say are 2k when they come out...admittedly the L3 will MAYBE last longer then the others with the electric use....but with the Titan getting 300mh the A4 getting 270mh
and the L3 getting 250mh as they all state standard.....the L3 loses some in 'slippage' with the bit extra hash of the others.
So as the title says...Meh!
Thought this would be a LOT rougher then this.
ANY scrypt POW miner today is IFFY...to say the least. The LTC to BTC ratio is 0.00457 ltc to btc as we speak. The price used above is $4.17c per LTC.
So we need (any scrypt unit running yet) at least imho 0.008 to 0.010 ltc to btc to make ANY of the units above...worth the estimated 2K I use above with shipping.
Also difficulty for LTC has gone up 20% in last 7 days or so. (ouch) the combo of price and ltc to btc ratio above has to change or it will be doorstop city imho.
The KNC Titans tend to be MORE for he reason..imho of their MODULAR nature...ie something breaks LIGHTFOOT on here can fix it ..and/or you just lose 1/4
hashing (1 cube) rather then maybe the whole unit...and they are hard to find, used though they are!
The A4's have a 45 day warranty and PROBABLY? the L3's also (I think?) . Looks like maybe if they go it is more like all or 1/2 hashing lost....if something goes boom.
Anyway take the poll. This was a lot and I mean a lot closer then I thought looking at the 400 watts for the L3..but the calc link above shows what it is from
www.litecoinpool.org NO FEE LTC pool at 103%...
Anyway along with taking the poll....post on here what you think of all this and the future of scrypt pow mining with how this seems to be lining up with all the
difficulty rises (LTC) and equipment and of course (imho) the crummy price for LTC as an example.
Also post your own views and modify my premise on above run your own calcs...this seems kosher to me ...but then again at one time I drank the BFL kool-aid so thus
silly hobby huh?
Here is the L3 speculation link
here is the A4 link on their issues with hash and firmware and trials and tribulations group buy results
KNC Titan thread (kinda light but their is lightfoot who can fix them...which is damn helpful....also the gen tarkin 3rd party firmware that imho has fixed them for another 2 years of use)
Do your own revisions/calcs...I was shocked on how close they all are even with the watts consumption
and everything. Use the above calcs and/or your own and post what you find here as well
hope it helps
