More like 1 MByte / HOUR at most even for larger ASIC rigs.
My entire farm was using less than 100 MB / DAY back when I was on a metered Sat connection (which I strongly recommend against, the high latancy was hard on stale shares, but the options I had at that location were ALL bad). 5 A2 Terminators, 5 S5 and a SP20, and some GPU rigs doing various stuff at the time.

Nothing behind for ether either, its potential is honestly bigger than any crypto out there.  At this point, the ONLY cryptocoin that can honestly say "we will survive for the long term" is Bitcoin - nothing else is even on the same PLANET much less in the same ballpark when it comes to market adoption by merchants, and without that there is NO staying power possible for the long term no matter how "technically superior" a coin might be. I am very strongly reminded of the Beta vs VHS wars - Beta was hands down technicall superior, but VHS was "good enough" and far better marketed and had much more widespread adoption and support, so Beta died after some years of competition. |

GLOBALFOUNDRIES Fab 1 in Dresden, Germany is currently putting the conditions in place to enable the site's 12FDX development activities and subsequent manufacturing. Customer product tape-outs are expected to begin in the first half of 2019. We're still looking at probably 2020 timeframe for someone to start building miners on that node, is anyone goes that route even if GF manages to hold to that schedual. Also have to wonder how much of that production is going to be tied up by AMD's aggrement with Global Founderies reguarding that fab (which used to be an AMD fab). |

I think bitmain now going to produce, mine and not for invest for development new chips for maybe years...
Because 14nm is not such move forward to invest much money what it need.
What you think about? Because if I am right, we can start nice investment in miners today. S9 will be here for long time.
14nm and 16nm are on a practical basis interchangeable - I forget which of AMD and NVidia is set up for production of their cards on BOTH nodes offhand, but that's just one example. 10nm and 7nm however should be significant moves forward - but I think Intel and IBM (respectively) and TMSC are all bit optimistic in their projections of when they'll be bringing these new nodes to market. 7nm in particular requires completely different "ALLOYED" wafers of a type that have never been done before, which is going to take time to get production ramped up. BW should have their LK-1402 second-gen part and miners based on it in production, but not a 3'd gen and haven't even announced plans for such a part. A721 was definitely rushed, as Caanan didn't even announce they were STARTING on a miner design 'till very close to the same time BirFury announced their new part and demo of sample, and shortly before the S9 started shipping. I'd guess the chip in the 721 is closer to the LK-1401 and isn't a "ful custom" design, as opposed to the LK-1402, BM1387 (S9), and the Bitfury part. As I recall, the Bitfury part is 14nm, I *think* the LK-1401 and LK-1402 are both 14nm but might be misremembering on those. Based on all of my reading, I'd guess we won't see 10nm or 7nm in miners before early 2020 - and I won't be shocked it it's more like 2021 sometime. I remember some of the early predictions of 14nm and 16nm process node "would be available" almost 2 YEARS before they finally were, due to the teething pains - then TSMC got hit by the earthquake and their shipping scheduals slipped a couple more months.... |

I predicted ZEC would join the "basket" of altcoins ballpark 2 weeks back.
Upgrades to the miners didn't change that - just meant you had to keep upgrading your software to stay competative.
As of right now, my R9 290s would be less profitable even with the optiminer software than they are running Genoil on ETH - but it's quite close - electric cost MATTERS, someone with high electric cost would probabl be more profitable on ZEC.
ETH right now is still more profitable than the week before ZEC was launched - but it's slipped down to only being a LITTLE more profitable with the recent price drop.

2 units 12th 2018 + 80 fee so 2100 for 12th
which is a huge premium for gear since bitmaintech will sell a 12 th miner for a lot less.
When they have the S9 in stock, that is. Interesting that Wells Fargo refused to do a bank transfer. I wonder if that's a Wells issue (they're NOT a good or even a fairly good bank IME with them) or if it's an Innosilicon issue? I see no real chance that ZEC pricing will go up significantly ever. Haven't seen ANY mention of ANY merchant that accepts the coin, which is the kiss of death for the long term. The only reason I see to buy an Avalon 721 is that Caanan has a better record on reliability than Bitmain has. |

ALL mining contracts are scams...ALL OF THEM.You will NOT get a breakeven on ANY of them................  I did pretty well (as did everyone else) on those contracts BitMain was offering for a while. Not HUGE profits, and not up to their claims, but definitely profitable. That was awhile ago too I bet. I did Hashnest S7 & barely got out what I put in by selling my shares just in time,I got VERY lucky.......... I didn't do the S7 ones, the return was WAY too low. |

WARNING:
Truly ask yourselves about mining profitability.
Take all of the Factors into consideration:
* There is an improved speed by about 15-25% for Claymore's v7.0 for ZEC
* There is an power improvement by 5% for Claymore's v7.0 for ZEC
* Previous Claymore's V6.0 for ZEC was 32% less profitable than Claymores Dual 7.4 for ETH
* There is a 14% drop in ZEC price
I add all of these numbers up and it does not seem profitable to mine ZEC unless you see some future profitability in ZEC holdings...I do not.
This forum has helped me so, I am hoping to help you in this information.
ETH profitabiity has also dropped quite a bit the last week - you pretty much have to crunch the CURRENT numbers on at least a daily basis. Also really need to factor in the other options as well, like XMR and ETC et cetera. |

As much as I like my 1070s, for almost every GPU-mineable coin out there the AMX RX series blows away the GTX 1070 on hash/$ and is usually a tossup at worst on hash/watt.
I only mine stuff like ETH and ZEC with my 1070s 'cause I was going to buy them ANYWAY and the ETH / ZEC mining has been somewhat more profitable most of the time since I started building my 1070-based machines.
There are a few exception but none of those right now are matching ETH or ZEC profitability (though XMR is close sometimes).
Best AMD-miner for ZCash is giving 30-50% higher sol/s on the RX 480 then the best NVidia-based ZCash miner on the 1070, similar power usage/hash, but the RX 480 is a lot less $$$.
The NiceHash miner is WAY behind the curve on the AMD side.

It would probably be less stable and harder to design for, and also use a heck of a lot more node-level support and data components and PCB space. Basically, it's worse enough that I didn't even consider doing it.
Comparing the top-clock efficiency of this pod to an S5 is comparing an S5 to an S5, since it's basically the same setpoint (800mV). Please also note that I specifically said it would only achieve that hashrate with modification to cooling and risks blowing up the regulator. I will probably never run one that fast.
At stock, you'd be seeing S5 hashrate at 400W. At bottom clock, you'd get it from 320W. And that's assuming your brick efficiency kinda sucks. Bottom clock is almost on par with 135-chip S7.
And yes, the efficiency is not impressive because the chips are two generations old. If I could do better, I'd be doing better. In fact, this whole thread is specifically about all the effort being put into trying to do better. If you want something better, it's way more constructive to try and help than to whine about what's common knowledge.
(sorry, that was rude. I'm kinda grumpy right now.)
OK I'm confused - I thought you were talking about designs for the new BitFury chips? |

Id imagine the only thing a scrypt miner would be use for is to mine shit coins and dump them at the first pump.
Litecoin has been pretty stable on price for over a year now, and is making me around a third of my current income on cryptocoin mining with my "paid for" A2 farm. I strongly suspect my income will drop some over the next year as more A4 units get sold and put online driving the network hashrate and difficulty slowly up, especially if Innosilicon or a 3'd party gets the current instability issues in the current firmware fixed, but I still anticipate my old A2 units will remain profitable at least that long or 'till I sell them to help finance an upgrade into something more efficient - whichever takes LONGER. ZEC is much more of a "pump and dump" coin than LTC is, especially given the near-continuous massive drop in price since it first came out live. Other scrypt "me too" coins though have turned out to have zero long-term staying power - and the only one that ever had ANY significant name recognition outside of the cryptocoin mining community was Doge. Litecoin on the other hand is accepted by more merchants than any other cryptocoin except BitCoin even now. |

Scrypt GPU mining ended in the fall of 14 without private kernels. x11 started up shortly there after, became unprofitable at the beginning of winter. Gridseed weren't ASICs either, the first ones weren't very profitable or good. You may have just remembered those little USB things coming out and thought 'well those were ASICs', they weren't. There were a lot of really bad ASICs. Gridseeds were never a good deal.
Unless you were running private kernels yourself, it wasn't happening.
What other algo are you looking at that's mature? Dagger doesn't count. That's a very niche scenario and it's bound almost exclusively by bus width. The GPUs never get a chance to even be close being fully utilized.
R9-290 has a 512bit bus as was already mentioned.
Who tests GPUs on sha-256? How about trying something remotely relevant to the discussion like say NeoS, Lyra2v2, or even x11. People haven't made optimized miners for Sha in years. As mentioned before if you're talking about 'theoretical usage' scenarios, video games are a very good example of that as GPUs are made to run as fast as possible on them.
Memory usage doesn't need to be about bandwidth or bus width, it could just be the total memory usage as well. Not just that, it doesn't need to be restricted JUST to throughput, it can utilize memory and still do a lot of processing on GPUs. At this point though you're just making shit up and theorycrafting again.
You can blame latency all you want, but Fury not only has a 4096 bit bus, but also gobs of memory bandwidth, it's not eight times faster then R9-290 or even twice as fast. It's not just all about memory speeds here or even latency.
The Gridseed 3355 WAS in fact an ASIC - and on scrypt it was more efficient than anything GPU based at the time by quite a bit. single side of an "80 blade" would pull 2.5 Mhash/sec at 40 watts where the best GPUs of the time were pulling less than half that at a LOT more power (7990 was an exception with it's pair of cores, it could actually manage a bit more than half the hashrate but pulled a TON more power to do so). Dagger (ETH) isn't "bus width limited, it's memory access limited - NOT the same thing or the RX 480 wouldn't even be close to matching the R9 290 on hashrate. For MOST usage, the Fury is a LOT faster than the R9 290 - but on ETH it's barely in the same ballpark despite the much higher "in theory" memory bandwidth. *SOMETHING* certainly keeps it uncompetative with much older cards with lower rated memory bandwidth. |

RX 480 has faster (8000 Mhz effective) but narrower (256 bit) memory than the R9 290 and R9 390 that gives it overall slightly better memory bandwidth than the R9 290 (5000 Mhz effective at 384 bit) but slightly worse than the R9 390 (6000 effective Mhz at 384 bit).
The RX 480 has 12.5% MORE compute cores (2304 vs. 2048 for exactly a 9:8 ratio) at quite a bit HIGHER clock rate than the R9 390 and even more so than the R9 290.
RX 480 and R9 390 are both PCI-E 3.0 cards, R9 290 is only PCI-E 2.0, but that has little or no measurable effect on most mining.
The RX 480 is NOT "close or a bit less than a R9 290" but in fact is a superior card across the board except ONLY for memory bus width
Might also want to pay attention to the R9 290x vs the R9 290 as they have the same memory system but the 290x has the same 2304 cores that the RX 480 does
 He's gonna need some ice for that burn. Good job fact-checking. What burn, that GPU-Z image just proves my stated facts about it. If you're talking about the "listed" memory speed vs my stated EFFECTIVE memory speed, keep in mind that GDDR 5 can transfer 4 bytes per bus cycle - on raw clocks the R9 290 and 290x run at 1250 vs the 2000 for the RX 480, so same ratio as I stated. I'm not discussing overclocked efforts, or it would be even worse - the RX 480 has demonstrated a LOT more overclock headroom than any R9 2xx series managed. Too bad the other 2 links appear to be broken, would be interesting to see what they were about. I don't need GPU-Z images for the R9 290 or R9 290x though when I have several of the first one and one of the second one and have worked with them quite a bit and have the bloody specs on them memorised. |

I think I paid $200 or so for my "27" - on sale from NewEgg a couple months back. Similar ASUS model to the one linked, but can do 1280 vert not just 1024 or I'd have never considered it - and had I realised it was a wide-screen I'd have passed on it.
IMO 16x9 sucks 'cause it's too wide - I'd actually prefer 1:1 if anyone still made those, or at least 5:4 (1280x1024 aspect ratio), but can live with 4:3

I had two days of intensive research and found the bitcoins is not profitable any more for beginners/hobbyists. So, I wonder if I can buy any Asic Scrypt miner for $150 or a collection of ones, Which can give me about 25MH/s. (I want at least $1/Day) Is there any Asic Miners for any algorithms other than SHA-256/Scrypt  So, you want to make in a year what a single $80 GPU can do in 2 months? Not on Scrypt. On the other hand, I've seen the Zeus X6 units in OPs's price range on rare occasion, and they're in the 25 Mh/s ballpark that OP was looking for - but 25 Mh/s isn't going to make $1/day at this point, more like 85c/day and slowly dropping (I forget what the actual hashrate out of the X6 was though, might be somewhat higher like 30MH/s). DO NOT try to mine Scrypt on a GPU - you'll lose money. Some of the other altcoins can be mined profitably on a GPU though, like ETH (Ethereum) ETC (Ethereum Classic) ZEC (Zcash) XMR (Monero) among others. Also, your laptop probably has a "GPU on motherboard" or "GPU as part of the CPU" setup, laptops almost NEVER have adaquate cooling to handle running these GPUs or their CPU 24/7 like a miner does and you almost definitely WILL KILL YOUR LAPTOP quite quickly. VERY BAD IDEA. |
