Mining News – Are 7nm ASICs a Thing? 1st Mining Equipment

Back te the day, the step from 55nm to 28nm chips wasgoed considered a sweeping progress. Some of the modern ASICs like the BW-L21 are based on 28nm chips and they suggest some awesome numbers hashrate-wise.

Nowadays wij also have access to 14nm ASIC miners such spil the Innosilicon A4 Dominator for Scrypt and the Ebit E9 Miner for Bitcoin. Those suggest even better hashrate/kilowatt ratio than ASICs based on larger chips.

Spil expected, technological progress does not zekering there. Evidently, IT companies are rushing to commence manufacturing 7nm chips and hardware that would be based on those.

(Lower numbers are better)

The four main competitors are Samsung, Intel, TSMC and Global Foundries. After investing about $ Four.8 billion USD into the development of 7nm facilities, Samsung took the lead ter the wedren and evidently is a duo of nm ahead of its competitors (no pun intended).

GMO Reaps the Benefits

Most of the mentioned companies expect to embark manufacturing products based on 7nm chips by Q1 2018. For example, AMD already announced that it is releasing “Starship” te 2018, a 7nm-based GPU with 48 Cores. So far so good, but what about 7nm ASICs for Bitcoin and other cryptocurrencies?

Recently, GMO – a Japanese internet giant and Bitcoin exchange technicus announced that they are partnering with one of the four mentioned companies to be able to develop a fresh ASIC that will be based on 7nm chips.

To receive the latest updates go after mij on social media!

Good news is – GMO will be selling those ASICs to the public. I will talk about it te a minute.

Bad news is – the company will also create their own mining farm te Northern Europe. Their project is to have 50,000 7nm chips to supply a total hashpower of 500 petahashes vanaf 2nd (PH/s). Once built, the farm will indeed be a considerable difficulty bomb and it will rank among the top ten Bitcoin mining pools ter the world.

Having such a solid background, it is very probable that GMO will eventually achieve their purpose and become yet another mining giant. This is indeed bad news for the mining community for visible reasons.

Now, let’s take a closer look at what might be considered good news:

GMO ASIC for Bitcoin

According to official announcements, the upcoming ASIC will produce Ten TH/s with a power consumption of only 500 W. It is supposed to be twice spil efficient spil Bitmain’s Antminer S9 that outputs 14 TH/s with a power draw of 1,372 W.

Also, since GMO is based on Japan, wij might expect better customer service and higher product quality. The implementation of cutting edge technologies will also means that GMO’s ASICs will very likely be the most expensive on the market. Wij will see.


Many experts agree that 7nm chips will bring mining hashsrate to a fresh level. However, personally I am still uncertain whether the switch will be spil big spil some voorkoop.

Let mij explain why. Back te the day, there wasgoed a loterijlot of hype around 14nm ASICs. For example, the A4 Dominator by Innosilicon wasgoed expected to supply 850 MHS vanaf kilowatt of power when mining Scrypt. That wasgoed amazing, considering that its predecessors with thicker chips could produce only 1/Ten of that hashrate.

Now, when the A4 Dominator wasgoed eventually released, it wasgoed able to output only 25% of the expected megahashes vanaf 2nd. While that wasgoed still an improvement compared to its 28nm predecessors, the leap wasgoed not truly that big.

Why MHS/kilowatt and Not MHS/$?

Before to proceed further, please share this thanks!

Spil you could notice, I base my calculations on MHS/KWS, rather than MHS/$. I do understand that ROI depends a loterijlot on the manufacturing price of the fresh chips and on the hardware that will support those.

Smaller chips are tighter to manufacture than fatter ones, which is why I do expect 7nm-based ASICs to be rather expensive.

However, I speculate that 7nm chips are here to stay for a while, Mostly because wij are about to succesnummer the ceiling of Moore’s Law. The next step after 7nm is 5nm chips. Now, te order to manufacture 5nm chips and make them reasonably priced, our industry has to make some significant technological advancements. I do not expect this to toebijten anytime te 2018 or 2019.

Therefore, I do believe that 7nm chips might become the “sweet spot” for ASICs for the next duo of years. This means that since wij are talking about a sort of long-term investment, initial price does not matter spil much spil maintenance and electric current costs. Obviously, I am making this conclusion based on what wij know so far.

The Bottom Line

I believe that 7nm chips will be a step forward, not a leap. At most, wij can expect a 100% improvement te power efficiency, compared to 14nm chips. Te reality, the number wij might get might be only a 70%, 50% or even a 25%, spil it happened with the Innosilicon A4 Dominator.

While wij all agree that 25-100% better power efficiency is still a lotsbestemming, it is not exactly a spel changer of any sort.

This also means that even however the upcoming 7nm ASICs are undoubtedly a difficulty bomb, those with 14nm chips won’t diegene off straight away. I suspect that the real difficulty bomb here will be GMO’s farm ter Northern Europe.

Thank you for reading. Spil always, your comments, suggestions and questions are welcome.
