Ok folks - I have a bad news and a good news - we won't see 40mhs on 1080... but I've tested 1070 today and for some reason - it does at 125-130w... 26.7mhs - so overall its very reasonable to buy if you consider price and resale value - its definitely better then fury nano (considering other algos
The only problem its in linux now and I dont know when they get wddm 1 driver working and whats happening with july release of Win 10 and wddm 2

oh finally a good news, so 27 at 130w, do you have proof of the wattmeter? 27MH at 130w is very good, but apparently the nano is doing somehting like 20-22 at 80w, so it's not worse at all...

still they will be pretty expensive, so i would avoid buying right now, you can buy a 970 for cheap(230 euro, used) that does 20.5MH/140w

Its nv-smi - didnt have time to catch with wattmeter - but thats stock - i think you could go lower with power target as you do with 970

can you try to set tdp at 60% with msi afterburner? not sure if recognized yet, and then measure again with smi

smi is pretty accurate, but there is a 5% error, for example in my case it say 135w mining ethereum at 20.5MH per 970, but it's actually toward 140-145w maximum

vaulter, MSI afterburner 4.3.0 beta should have support for 1070/1080. Any chance you could try it?

I can try it but not for ethereum - this perf is on linux only - there is no fix for windows yet (low hashrate)
And i dont know how to change power target under linux
But comparing with 970 i do get 140w with the same settings where i get 125w on 1070 at stock settings

26.7MH out of 32MH of full bandwidth is about 83%. That's what most cards approximately do. Still a mystery why the 1080 did only 24.5. Should be around 32MH if you take the 80% efficiency rule.

Finally good news. I will hold on buying the AMD R9 390 and wait for the price of 1070 to drop to reasonable levels.

Someone had a review unit they posted some ETH hashrates on - it was..... VERY VERY underwhelming, a 970 outhashes it.

Not sure how much of that is "new drivers not optimised for OpenCL or CUDA compute yet" and how much of it is "archetecture changes made it work WORSE on Ethereum than NVidia cards already do"....

they perform surely better on any other algo, due too low consumption and better hash, so i think it may be true that it is just a matter of bad optimization, or lacking of something necessary

genoil said that their potential could be around 40MH, for the 1080, which would be an instant buy.....but anyway, still too pricy for my taste

The maximum of the 1080 is 40MH, just like the max of 290 is 40MH, because of the bandwidth of 320GB/s (simply divide by 8KB/hash). I've heard through the grapvine that Pascal will be able (but does not yet) support (TLB) page sizes of 2MB and 8MB. When this would be enabled, we might finally see hashrates up to copyspeed (40MH) on NVidia. What we've seen with current drivers is much less; 650KH/s on Win7, 6MH/s on Win10 and 24MH/s on Linux (OpenCL).

Have you seen anybody achieve the 40 MH/s on the 290 or 390?

Why the 390x is the same speed as the 390?
