Nvidia GPU more powerful to crack ?

Not years, not centuries, not even millennia.

Here's the amount of years it will take:

which is a pretty long time considering the universe is somewhere between 15 billion and 20 billion years old.

Here's that time-analysis thread again:

The only hope of cracking WPA is if you know that the passphrase is only a few characters long. If it's a long passphrase though, our sun will have gone supernova and swallowed the Earth before you ever come close to bruteforcing it.

Well, you could always get lucky and end up crackig it within the first 10 minutes :P

Well, just tested out the 295 GTX (Nvidia's Most Powerful Graphics card currently on the market), and sorry to report that the benchmarks on pyrit were pretty dissapointing. They're no different than the 280 GTX:





The average is about 10,500 PMK's/sec which is about the same as the benchmarks for the 280 GTX.

Essentially, the 295 GTX is a dual 280 gtx, so I'm assuming that the current CUDA drivers do not take advantage of the second GPU.

Good info, thanks for the follow-up.

Still, at 10K PMK's/s that is still blindingly fast, albeit a disappointment for the newest nVidia card. Fact is, my dual CPU BT3 achieves less than 100 PMK's/s running aircrack-ng and a dictionary. Yeah, old system.

Try notifying the author of your findings. He will at least appreciate the numbers, and at most offer guidance to unlock that 2nd GPU lurking in your card. He seems very responsive to questions posted in the WIKI section of the google code page. Perhaps you'll see 20K PMK's/s ?

Or, we could all just wait until Shamanvirtuel finishes the GUI front end he's been asked to write for pyrit... Either way, the results should be very interesting.

Hi all;

Can you tell me why GPU are so interesting compared to dual/quad core CPU ?

Thanks

Because GPUs have many more ALUs than CPUs

[joker5bb]

it shows here
code.google.com/p/pyrit/

that the gtx 295 does more pmk/s than a c1060

how is that possible?

[purehate]

Because all a C1060 is is a 295gtx with no video outs, more memory and addressing specially tailored to fit CUDA programming. This is necessary when programming protein building or something of that nature but for password cracking its not needed.

I always thought brute force was a last resort for security gurus...
