VIA Padlock, interesting for bruteforcing hashes?

Hi,
today I read the news about Via releasing a new generation of their low-end CPUs, called Isaiah. The most interesting part was about the Padlock technology. That's a set of features that, briefly, consist in an hardware implementation of some of the most used security algos. For example for SHA1/SHA256 VIA site claims an encryption rate of 5 gigabits per second. Just for the sake of curiosity I made a very simple calculation and found about 7M words per second for words consisting of 8 characters. Now, I could be thinking totally wrong but wouldn't be these figures higher than what is a standard house computer able to do? These CPUs are also much less expensive and could be easily made to work in communicating "clusters". What do you think about? Any experience?

Thanks for the attention.
