I searched when I was getting like 24 mh/s and people were saying that was average for a 1080 also. Does it just depend on the algorithm then? Maybe my miner was just showing wrong before.
Yeah it sounds like you switch from Ethhash, or Ethereum mining to Equihash. 24 mh is about right for a 1080, I think if they have Samsung memory they can be pushed a bit higher.
I have seen people get 27+ with rx570 and rx580 are you sure 1080 cannot get higher? I thought it was a better card. It costs more. Can't you get 30+ with a 1080?
GDDR5X has latency issues that severely hurt Ethhash mining on the 1080 and 1080 ti.
This appears to be WHY the GTX 1070 had HIGHER ETH hashrate than the 1080, and fairly close to the 1080 ti even though the 1080 ti is a MUCH higher end card.
No, the 1080 will NOT achieve 30+ ETH Mhash, unless you get INSANELY lucky on the silicon sweepstakes and can OC it a TON higher than most manage - and likely not even then.
1080 is a better card on algorithms that are NOT severely memory-limited though, like equihash used by ZEN/ZCL/ZEC.
