BLAKE2 is a very good alternative if you want software performance: https://blake2.net/.

Just stop what you're doing and look at scrypt, bcrypt or even PBKDF2-HMAC-SHA512 if you're thinking something that involves the words "passwords" and "fast hash function." (http://throwingfire.com/storing-passwords-securely/#notpassw...)
