That's not true. They can release a new ASIC every month only because they started developing them last year. A new algo is safe from ASIC for 6-8 months. Some coins (Monero IIRC) have plans to fork every 6 months. Just the threat of that is enough to deter ASIC development for that algo.

Look, it doesnt make sense. It will cost too much more, have very little to mine and be at the whim of the antminer E3 pricing basically lol.

Most important question. WHY just WHY do u wanna make an FPGA when one asic already controls 64% of GPU mining? A few asics control most of the GPU mining already.

And this FPGA u are doing is just another GPU. Why? Because anyone can do it. U make a slightly stronger GPU known as FPGA. All u need is abit of dumb money going in there and u make no profits due to high difficulty.

In my opinion, interest to FPGA can be short-term, when you need to mine a certain number of coins before the release of ASIC. Like a Groestl, Nist5 and others.
But a more fundamental interest may be to offer a useful proof of work function  which can also be ASIC-resistant.
By setting new standards for the usefulness of the POW function, we will strengthen mining on FPGA in the long term.
In the end, someone uses mega-FPGA cards in real life. For what? Amazon AWS earns with them, why not do the same?

I fully agree with prospect of FPGA vs ASIC but the point is that you are not that dependent of one manufacturer. There is no reason to wait for E3 for example over 3 months right, since its basically a nice packed GPU rig. and by the time you get it everyone gets it. Imagine that you can mine now CNv7 with 1 card @ 64Khs. Also the flexibility and consumption vs GPU is pretty good. Agree that the pricing is out of range for most miners....

you make some good points. i do think you are not taking some things into consideration though, and thats the versatility and longevity of something like this.

i will be buying a xupp3r (although i will use ddr400 memory at 1st, as the qdrii+ is crazy expensive).

why? its not to compete with asics, you cant. i own none and dont intend to buy any, im GPU only with a power budget of 1500 watts (my self imposed limit, no reason i couldnt do more). its because i want the power efficiency and density that a fpga can give me. plus the versatility.

sure any current or new algo can have an asic built, but it will take time. a fpga is more nimble, load a new bitsteam and go. for that period of time of no asic for the algo, the fpga will rule compared to gpus.

also there is no reason a xupp3r cant last for years and still be pretty competitive even against other fpgas. sure new ones may come out that are more energy efficient but not by orders of magnitude. as long as it has the capacity to fit the bitsteam it will be useful. thats why i figure ill go with the xupp3r as it seems the most advanced one of those being discussed here, and it has the most connectivity (link up to 4 of them for any algo thats too large to fit in one unit).

plus, i like playing with new tech. give me a reason to learn programming (although i will never be good enough to bang out algos) it will be fun just to play around. what can i say, i like shiny new toys.

will i lose money on it, possibly. but thats the chance ill take, and if i do lose, no regerts. for me the tech is the most fun. if it loses money, well im sure i could find another use for it, at least something better than a doorstop anyway.

Maybe u have too much guts lol. The crazy expensive part is the problem. It is more expensive and less efficient. Versatility just isnt worth it when mining difficulty will go to your coins anyways due to new and current asics. Asic manufacturers can flood the market like crazy. It wont be the first time.

Perhaps u can update on the total expected cost and hashrate of its best coin when u get the info.

No, it looks like you have strong feelings on this subject

Most other posters have a much more pragmatic approach. I've been mining with GPUs and ASICs so I'm quite sure I have a fairly good grasp on how this works. You're dismissing a lot of variables - power consumption, density, forks, exchange rates, etc. BTW the best time to be a GPU miner was when there were cheap GPUs flooding eBay.

OP said these cards take 100w - 160w.. they'll be profitable on something for a while. People aren't going to mine algos with GPUs that lose money lol From the sounds of it these cards will remain profitable long after GPUs are no longer possible. The arguments here are cost vs hashrate vs GPUs.. but you have to remember that the GPUs will consume significantly more power than the equivalent hashrate of a GPU rig. You're also repeating yourself over and over again which honestly seems like you're attempting to just scare people off from the idea of using these cuz 'muh ASICS are coming for everything'. I think everyones aware of what happens to other cryptos when ETH either goes ASIC or Proof of stake.. the insane amount of hashrate pointed at ETH will move. Markets adapt.. at this point I think a lot of anti ASIC cryptos are getting annoyed with these ASIC companies and will likely create a plan to have backup algos slightly modified to switch to prior to an ASIC being released for their current algo. The current ETH ASIC aren't super awesome. At 800 they're decent but add on shipping an a PSU and it pushes the price up.. they can't just flood the market with these or they'll kill the profitability on ETH and they won't sell more of them or possibly annoy ETH devs to the point they really do fork. If anything the current ETH ASIC is likely just going to put a cap on the profitability of ETH.. when ETH increases significantly and GPUs are scarce they'll be able to dump another round of ETH ASICs on the market essentially capping the profit at a certain point to a certain extent.

I dont have such feelings lol. This is kinda obvious. Bitcoin + mining is a small portion of my assets. Just because it works before doesnt mean it works always. It is human nature to be resistance to change though.

Those GPUs will be there because it is not profitable to use them. Ok then, I guess it is time to put your money where your mouth is.
Perhaps update the cost and hashrate when u buy and program these FPGA then and the profits lol. Lets see.

i am repeating because it is quite ridiculous. lol, wat adapt when it is 64%.
Look GPU is 2500 USD for 180mh and E3 can be as low as 800 USD for 180mh. It is somewhat similar to the S9 vs S7 where the S9 is 3 times more efficient. In this case, efficiency is same but cost is far lower. It really depends on E3 pricing. More expensive and less efficient eventually becomes obsolete or cant break even.

There is nothing to gain from scaring anyone haha. If u lot buy into asics, it will increase the network difficulty alot because asics are cheaper on a per hashrate basis. If u lot buy this FPGA instead, it will increase network difficulty far lesser since it is more expensive per hashrate basis. I should be abit happier that more mining money of others will be soaked up for less hashrate. I am not though, doesnt matter to me. I own no GPUs now, juz some asics.

Good luck to u and perhaps track your numbers here too ya.
