It is especially hard to find 1070's as they are the product most in demand by the miners. The 1070 easily surpasses any 1080 in hash rate. Crypto miners won't touch a 1080, so they are left for the gamers to purchase.

Could you please explain to someone who has never done crypto, how a 1070 can outperform a 1080? Would that be productivity/watt, or some other metric, or just somehow is faster?

I was wondering the same thing.

With each crime and every kindness we birth our future.

So... the 1080 is the fastest? Color me confused.

---

I thought it had to do with cost of electricity to mine a certain percentage of coin relative to what you paid and how long it will take to recoop the cost. Also, you don’t run them flat out. There’s a power curve where you want the optimal current, usually less than full speed. I don’t do it but got a friend that does

---

I would guess in the mining world capital cost and running cost both come into the equation.

Its because of the GDDR5X memory used on the 1080. The 1070 uses normal GDDR5 memory. The memory bandwidth is greater on the 1070 than the 1080 for crypto mining. The hash rate is how crypto miners benchmark hardware. The hash rate for 1070's is larger than the hashrate for 1080's. This is a well documented and published discovery in the crypto mining community. I have never done crypto mining either. I do read about how miners get the most performance out of their gpu miners and came to this known fact.

The benchmarks posted I have not seen before. The commentary in all the crypto Reddit posts and forum threads said the 1070 was preferred over the 1080. Must be because of the power usage per sol or something.

From a Reddit post:

Only some algorithms depend on memory performance. DaggerHashimoto (Ether) is pretty much the one of most concern. Honestly, since Eth is not a top performing coin right now, it doesn't matter.

The 1070 Ti is untested so far, but it will likely outperform the 1080.

Already gone. I am still holding out for a Hybrid card. Two in fact for the middle card in my gpu sandwiches.

There are a couple 1080Ti Hybrids, and a couple 1080 non-Ti air cooled cards available right now, but no 1070Ti's sadly. Also some 1050 & 1030s still. As well as a couple 1060's.

Will be interesting to see how long this pricing surge lasts, as both South Korea and China have announced plans to regulate (Sth Korea) all the way to shutting down exchanges & large scale trading, and even mining (China).

This whole crypto mining craze is a textbook example of the "irrational exuberance" speculative bubble that goes back to the Dutch Tulip bubble in the 1600's That is why every financial expert has said to stay away from it. BTC is down 50% from its high in mid-December. There are going to be some major failings that will cull the market. The blockchain technology is here to stay but won't be tied with currency solely.

A Dutch supercomputer called ARTS that searches for Fast Radio Bursts (FRBs) may be at the base of the shortage of GTX 1080 Tis in The Netherlands, as it sports 200 of them (plus probably at least as many for replacement in case of defects).

Fast Radio Bursts (FRBs) are extremely bright flashes of radio light, that travel billions of light years to reach Earth. Discovered over a decade ago, their origin and nature are still largely a mystery. Because the flashes last only a fraction of a second, they are easy to miss and very difficult to observe. Therefore, only about 25 FRBs have been discovered so far.

That is now going to change with Apertif, the new wide-field cameras for ASTRON's radio telescope in Westerbork, the Netherlands. Apertif has the largest, most sensitive field of view of all radio telescopes in the world.

To find FRBs, Apertif needs to continuously make a high-speed movie of the radio sky, at 20.000 frames per second. This requires new, more powerful brains. "To form and process all those images, we need the computing power that only the fastest supercomputers in the world can produce", says Joeri van Leeuwen from ASTRON and the University of Amsterdam. "But we did not have such a computer yet. That’s why we designed and built this one ourselves."

Tweakers.net has a Dutch article about the speed it reaches (2 PFlops)

Numbers:
Data rate: 4Tbit/sec
Storage: 2 petabyte on 320 HDDs (*)
Speed: 20,000 8bit images per second

(*) because these can be written to continuously, whereas when SSDs are used, once these are full, write speed drops immediately to zero.
Also, the amount of SSDs one can add in a server is finite. Aside from some absurd/stupidly priced 60TB/16TB SSDs, the comparison was made between normally available hard drives and solid state drives. It was found that for maximum space, one HDD's space would need several SSDs. And since write speed isn't an issue (150MB/sec on average is enough), the choice was to add 320 HDDs.

Fun image: Seti would be jealous.

Not all of the 4Tbit/sec is stored. Pre-processing by 50 nodes cuts that down enormously.. These nodes consist of:
CPU: Dual Intel Xeon E5-2680v3 2.5 GHz (12 cores, HyperThreading disabled)
Memory: 256GB @ 2133 MHz
Disk: 2x 300GB 10Krpm SAS RAID
Network: 2x 1GbE, 2x 10GbE, 1x FDR InfiniBand
Part of which have 4 TESLA K40C GPUs.

holy cow!

What kind of backplane would they use to put 200 top end GPUS together in a string? In the world here where us mere mortals reside, we're lucky to get 3 x16 slots in one board, maybe a few more with dual proc systems designed with some addl PCIe lanes, but still, nothing even close to resembling something that could handle that many cards running full bore at once. As it is being done though, I guess all it takes is $, eh? :-)

---

I don't think that you would backplane all the gpus. Don't think that is possible. I would think they would use some form of the Hypertransport optical links that they use for cpu clusters in supercomputers. If you can put cpus onto that kind of link, you probably can do the same with gpus.

doubt if retailers will pay much heed to anything Nvidia says about selling practices.

I agree. The retailers will just chase the dollars. They could care less where they come from. The crypto miners are flush with cash from their profits. They will continue to buy up all available stock in large batches.

Think that there's any chance that Nvidia will monitor etailers, and if they see that they are selling them in quantities of more than say 2 per cust, they'll have their partners shut down their supply? Pie in the sky I know, but this can't be good for them in the long run, esp if/when the market crashes again and gets flooded with 10,000s of used cards. Though as usual, $ talks...

I'm just wait the day when "sanity descends" on the world of crypto currencies and they start to return below 1c/1$ There will be much grinding of teeth and a number of folks will find that the piles of silicon in their garages are worth less than piles of sand....
