Rumour time! According to ChipHell (https://www.chiphell.com/thread-1588175-1-1.html), the new GTX Titan "P" and 1080 Ti will be based on GP102 and not GP100. The major difference of the the Titan P...

Post: RE: GTX 1070 & 1080

I bet the lowest belong to the stock clock of 1607 Mhz, and the other results are from overclocking the GPU by a bit. I'm not a fan of automated overclocking shenanigans and luckily GTX Titan has sta...

Post: RE: GTX 1070 & 1080

According to my preliminary calculations, 1080 should do ~18129M p/s at stock clocks (no boost) for MD5, but since it's derived from old gen's data (Maxwell), the estimation should be skewed, either u...

First thing, it's a raw wordlist attack, those tend to have lower speeds/utilisation than mutation / brute force attacks. Second, I can see that the cache is set to default (32MB), which is why the wo...

Fab reduction from 28nm to 16nm is a big deal, let's just hope it's done optimally architecture-wise.

    Thread: CPU and GPU in same box?
Post: RE: CPU and GPU in same box?

Rolf will chime in and say that GPUs beat CPUs in terms of performance/$ and performance/W, so running a pure CPU cracking box for a bunch of generic hashing algorithms isn't very efficient.

Short answer: attack WPS through reaver. A slightly longer & educative answer: Check this out (https://hashcat.net/wiki/doku.php?id=combination_count_formula) and be amazed how long will it take.

So, in this specific example, Titan X is ~7.2 times faster than Titan, both being overclocked. Serious performance increase over old gen architecture.
