what about other algorithms ? like Equihash , NeoScrypt , CryptoNightAlloy , ..... ?
can i get the 660 Hash/s on another algorithms to?
Nope, the hashrate for the cards is different on every different algorithm. If you go to
https://whattomine.com/ and enter in one RX 470 card, you'll get an approximation for how fast a 470 can hash on the various algorithms that are listed on the site. It's unclear to me whether or not the numbers given are for a 4GB card or 8GB card, but they should be about the same for your 4GB 470s.
