ETH GPUs miners beware!

[MagicSmoker]

I design ASIC's for a living.  I implement them in FPGA before we tape out.  (Not for crypto)..

The sheer volumes of memory bandwidth needed, and the costs, tell me that someone is smoking some seriously good shit.  I get beat up over 64k of RAM.... 

will you elaborate a bit more? are you saying that the cost of equipment manufacture is not worht designing such an asic miner? THanks.,

If it were me.  And I had the resources. I would make asic for Ethash just to say I got it done when so many day it’s impossible.  When you make billions of profit a year and look to do the same this year.  What’s a few 100k to dabble with an asic for fun?   Anyway cost isn’t the issue here. I’m sure it’s well worth it to learn what an asic can and can’t do.  All about learning.  Look at what we spend yearly on school.  This is just drop in bucket.

@rem26 is right - and I'm an EE, as well. To put this into an analogous terms, an ASIC designed for Ethash would replace the GPU core, not the GPU memory, and as anyone who has tinkered with Ethash knows, the speed of the GPU core has very little to do with hashrate; it is entirely up to memory size and bandwidth. THAT is why Ethash is considered "ASIC-resistant."

Ethash is memory bandwidth bound...I don't think ASIC can help much there...
and if bitmain can solve that, they better start making graphic cards, they'll earn more money

They did start making graphics cards.  In a sense. Checkout sophon.ai

I wonder if this means an ASIC for cryptonote coins like Monero are just on the horizon then? I don't know the exact details but I think some of the reasons cryptonote is ASIC-resistant are the same as ETH.

Roughly 70% of monero network hashrate are comes from large botnets like javascript webminers coinhive, etc. So there are no economical space for asics on cryptonight - memory hard algorithm

That is one of the reasons why is not on their asic roadmap, is just not feasible which translates to being not worth to create an asic for it.

Good luck making an ASIC with 4Gb ultra-fast memory to each processor.

The way you say, it looks like you are the top engineer of a multi-billion dollar semiconductor company, the reality of somebody or some people can do must be painful to you but don't worry troll, if one or some cant maybe another one or some can.

More importantly, the main bottleneck in GPU production is memory availability, there's just not enough chips. Even if these devices do materialize, they will simply be priced relative to their performance compared to GPU's but they wouldn't take over the market because they couldn't be produced in large enough volumes nor would they be that much faster than GPU's.

Where are you? Do you live in this planet? It does not look like that. GDDR3 has its own manufacturing plant, memory availability is not a problem cause few things use GDDR3 nowadays.

There’s a worldwide shortage in memory availability... fairly common knowledge. It’s like saying there isn’t a GPU shortage. Hello! Yes there is. It’s amazing how incorrect you are on virtually everything you post lol

[Viecoin]

I could only imagine the hashrate. I doubt there will be that many produced as the demand may drive up the price and scarcity of memory.  I'm wondering if this rumor coming into fruition would preempt the Casper fork.

[Metroid]

Yes and only for 90% GDDR5 and 10% DDR4. Do you really believe that for DDR3 or GDDR3? If you do then it means you are clueless about whoever manufactures them, So I will leave to that, there is nothing to talk about.

[jstefanop]

This kind of makes sense assuming the numbers are correct for 32GB per 6 asics on each board. That means about 5GB of memory for each asic. If they are really using DDR3 (which again makes sense for an ASIC style eth design, since 96 GB of GDDR5 would be crazy expensive), they could probably get away with a 256 bit memory bus running at 933mhz (near max of DDR3). That would translate to about 60GB/s per asic or about 7mh, x 6 = 42 MH per board or 126 mh per machine at probably 200-300 watts.

Nothing crazy but is the equivalent of a 6 GPU rig, for probably half the power cost at half the USD cost.

I think theres some faulty math going on here, the article says 6 chips and 32gb per board, 3 boards, and a total of 72gb. Also it says 32 1GB chips ... how many 1GB DDR3 chips have you ever seen jstenfanop?
Now if it were 24gb per board, that would make some sense as thats 6 x 4 so each asic/gpu gets 4gb. In any case, no chip designer is going to go with ddr3, and a 28nm process for prod, maybe for a test/tapeout but not full scale prod, it'd just be stupid. This is just pure vaporware.

Also guys quit hating on Metroid, hes just salty he missed the mining bus, let him enjoy these few moments he gets, however fake they may be.

Here you go :p

1GB x16 wide  933mhz chip super cheap DDR3 chip. Either way something is wrong with the article since the numbers don't add. If they are doing something like this would make sense to use 512MB x16 wide chips for lets say 4GB of 128 bit wide ram per core. Then your looking at like 7 or 14 MH per core depending on number on memory interfaces per core.

You don't need anything crazy on the core to do the hashes...going lower than 28nm for an eth specific asic is what would really be "stupid" as you put it.

Only reason eth asics have not come out is because GPUs have still been more economical, but with current eth prices that changes. An eth asic is essentially a GPU with a much smaller compute die and cheaper memory.

One of these cores would be about $10 bucks for the asic core/memory controller, and another 20 bucks for the 4GB of DDR3 ram. So your looking at around 30 bucks per 14 MH core (lets say it has 4 memory interfaces).

So bitmain is looking at the current market and are like hey 30 MH GPUs are selling for 400 bucks, we can make the equivalent with 2 ASIC cores for 60 bucks and sell it for 200 with a fraction of the power consumption = win.

Almost all modern GPU's today use GDDR5 memory though so what he said about memory shortages being a bottleneck for GPU production isn't wrong since you yourself confirmed that there is indeed a memory shortage for GDDR5 memory. You won't find anymore high end GPU's using GDDR3. At best, some companies still manufacture older entry level GPU's from the NVidia 600 series or Radeon 5000 series that are used in industrial settings or for HTPC's. But you wouldn't want to be mining much with a GeForce GT 610 or Radeon 5450 anyways.

Exactly, most of these trolls don't understand what that means.

Yes now they can build asics for eth and sell to idiots cause they are paying $1000 for a rx 580 30mhs, imagine how much idiots would pay for 350mhs, develop a 350mhs eth asic and put a price tag of $9999 and will be millions of idiots on the queue to buy it. If the rx 580 was selling for $180 then it would never happen.

[pbuva]

Their usual business tactics is to run the year themselves and then sell them to the public as new ones. So the difficulty will not be increased if they are sold, they are already running today. If there is any truth at all.

i am not familiar with the mining algorithm software however still involve din sofware dev in diff project. This kept wondering why they make slight mods to an mining algorithm such that it is no longer mineable by asic. I mean asic is 1000x faster than software but use the software adv. against the asic, which is flexibility and speed of development.

[Marvell2]

btw fuck you admins for constanly deleting my posts , others post way less useful or frivolous shit and you constantly delete my posts fuck off

[whoismoses]

...Yes now they can build asics for eth and sell to idiots cause they are paying $1000 for a rx 580 30mhs...

You have probably said this line a 100 times in the last couple months. Who pays that much? RX 570/580 can be easily gotten for $500 (which I would never do) and with just a tiny bit of effort can be gotten for $329-$400.

What evidence do you have that there are a ton of idiots willing to pay $1000 for a 580?

[ggbtctalk000]

one article regarding nvidia crypto mentioned about why nvidia and amd can not supply enough GPUs to market during this white hot demand is because of the manufacturing company TMSC is in full throttle and no f* way to meet the demand. nvidia and amd only designs it. So logically thinking if bitmain can manage to come up something for ETH i think hye will be on same situation and supply constraints faced by GPUs. Under the hood, I expect the similar type IC and chips for doing the mining.
