Is my test results normal?（oclhashcat-plus for truecrypt ,2*gtx690)

[helloworld]

I use 2*gtx690, result as below:
•PBKDF2-HMAC-RipeMD160 / AES: 95.6kHash/s
•PBKDF2-HMAC-SHA512 / AES: 130 kHash/s
•PBKDF2-HMAC-Whirlpool / AES: 30 kHash/s *updated*
•PBKDF2-HMAC-RipeMD160 boot-mode / AES: 187 kHash/s


Comparison of the results of the official release：

Here are some speeds from 2x hd6990:
•PBKDF2-HMAC-RipeMD160 / AES: 223 kHash/s
•PBKDF2-HMAC-SHA512 / AES: 95 kHash/s
•PBKDF2-HMAC-Whirlpool / AES: 49 kHash/s *updated*
•PBKDF2-HMAC-RipeMD160 boot-mode / AES: 451 kHash/s


I think two result difference is large, Is there the results of the official about gtx690? thank you!
