Bright Side of News reports ElcomSoft's password cracking software runs fastest on the Radeon HD 5970, which is pretty remarkable as this software uses CUDA to enable GPU acceleration.
The very interesting bit and a bit of a slap for AMD's public stance on how "CUDA is a closed standard" and developers that go developing with CUDA will suffer when they decide to switch to open standards… in reality, that is nothing else but hot air. ElcomSoft used CUDA to enable GPU acceleration in their software code and they're proudly showing "Designed for CUDA" logo on their site. Yet, it is the simplicity of CUDA code that enabled AMD's version of the code to execute in "ass-whooping" way and passed the magical barrier of 100,000 broken Wireless passwords in a single second - a number security agencies will certainly appreciate. Thus, AMD Radeon HD 5970 has killing performance on Designed for CUDA application. Interesting, right?
