This is the keccak algo. Can be mined in nicehash/zpool.ca or coins directly.

some of the coins:

smartcash
maxcoin

gtx 1070:

ccminer 2.2.2 does around 650MHASH (ccminer -a keccak --benchmark)
ccminer alexei does aound 775MHASH (ccminer -a keccak --benchmark)
ccminer sp-mod #3 does around 900MHASH (ccminer -a keccak --benchmark)

The 1080ti is not yet tested, but I expect 1500-1600 or more.

You can become a donator and test on the 1080ti. (0.05 btc)
