Is my test results normal?(oclhashcat-plus for truecrypt ,2*gtx690)
#1
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!

nvidia is bad, pretty much the official word
#3
AMD has both more raw power and a the better integer instruction set (floating-point doesn't matter) and thus it's better for crypto, since crypto only uses integer instructions. That's the reason why its generally faster than NV in crypto.

But, AMD has bad support for 64 bit instructions or at least worse support than NV. This makes it bad when it comes to 64 bit based algorithms, such as SHA512.

Here are the results for a single GTX Titan.
-m 6211: 74015
-m 6212: 33988
-m 6213: 10592
Price: £800

Radeon 7970.
-m 6211: 59108
-m 6212: 25180
-m 6213: 12987
Price: £319

MAD is far from losing I would say.

Is this about right for 4 7970s? Should I even mess with overclocking? I do have them watercooled.
