I think I can get my 980ti to mine @ 1GHASH as well. But a waste of time.
They tested the opencl bitcoinminer, wich is slower than ccminer.
You can get the performance of the 1080 for free if you just know wich software to run.
And which software as of now is the best to run on the 980ti to get 1080 hashing power?
Has this changed in the last 2.5 months that is was posted?
Status after 2 months:
Dagger Hashimoto (Etherum, etherum classic) is still 5MHASH on the gtx 1080 (windows) The 980ti can do 22MHASH on standard clocks.
Neoscrypt is 700khash on the 1080 and 1,2MHASH on the 980ti (with djm34's opensource kernal and oc)
Lyra2v2 on the 1080 does 52 MHASH with the nanashi bins (1.7.6. release 12). and 42MHASH on the 980ti (with oc) sp-mod private #7 (1.5.80 sp-mod #7 run with -X 64)
Gtx 980ti vs gtx 1080 (Most profitable memory algos)
Etherum: 440% faster
Neoscrypt: 70% faster
Lyra2v2: 20% slower (Because the kernal has been optimized for the pascal chips in 12 releases )
And for the other algos like x11,x13,x14,x15 quark-and-qubit you can soon forget gpu's because there are asic's comming..
