Graphic cards gpu technology breaks passwords faster than every cpu!

I got around the progtram IGHASHGPU  and rapidly found that graphic cards gpus shouldnt be underrated these days! 
ighashgpu

An AMD Radeon 5770 can crack an standard password with 5 characters in under one second, a normal cpu with about 3GHz would need to spend about 24 seconds on thsi operation.
Another password with about 6 characters uses an normal CPU about 1 and a half hour, while the GPU of the Radeon 5770 manages to crack this word in ~4 seconds.
With an passwort with 7 chars where one is an space, an normal CPU would need about 75 days for this operation, our GPU fucks the password up in about ~7 hours!

So in future if we think of an SLI moded Graphiccard with more power than this mid-range card we used here, passwords could be breaked really fast in no time, what took as about 50 years for now can be done i about 5 weeks or less depending on the GPU powers...


so long here is an crack report of multiple GPUS with IGHASHGPU:
for example, result for HD5770+HD4770+8600GT looks like:

Gert some GPUS get yourself an lawyer, an insurance, some passwords and crack the hell out of em! CHEERS
Tramadol
 As my picture above describes, i will get me a bunch of tramadol or zolpidem and chill out till my 12 char pw got cracked =P cheers folks!

  2. that is extremely power stuff!

  3. It's surprising to see a video card calculating this particular thing faster than a processor, pretty cool info.

  4. It is because graphics cards use a floating point cpu and not a math co processor.

  5. Forcing passwords, such a brutal method! I prefer to use a keylogger and be as subtle as possible. :P Still, guess this means I need to invest in a better graphics card.

  6. o-o you'll be having fun...

  7. Mythbusters did a good comparison between CPU and GPU. CPU does one thing, in a linear fashion where GPU does everything it can at once.

  8. my graphiccard is so old i think it needs longerthan my cpu...

  9. Good to know. Some NVIDIA cards provide extra performance boosts for some audio engineering applications.
