Graphics Cards are Better than CPUs at Cracking Wi-Fi Passwords

100°
274w ago - There's a lot of software out there for cracking wireless passwords, and most of it is legal. Why? Because it's sold as a way for network administrators to 'test' their network's security.

Of course, there's nothing to stop you 'testing' a network that you don't own, in a coffee shop or airport, for example.

Most cracking programs use your PC's CPU to do the hardcore number-crunching, but it turns out that the graphics card is actually far better at doing the kinds of calculations necessary.

How good? Well, an above average quad-core CPU, the Intel Q6600 can only accomplish 1,100 passwords per second, whereas a similarly above-average ATI HD4870 graphics card can smash through 15,750 passwords per seconds.

Who woulda thunk it? Luckily, we might be seeing some of this power hit regular programs too, with Nvidia's CUDA, ATI's Stream, and Apple's OpenCL frameworks.

The graphics card isn't best at every type of calculation, but if a program can intelligently route calculations to their fastest solver, then we could see blazing program speed increases in the near future.
 

GTA 4 Benchmark with Seven ATI and Nvidia Graphics Cards

50°
278w ago - Grand Theft Auto 4 caused a lot of problems on its launch: crashes during startup, the copy protection and the performance annoyed the customers.

By now Rockstar reacted and delivered a patch which fixes several bugs and also makes it possible to test several graphics cards without complications.

In order to keep the framerate at a moderate level we use maximal details, but restrict the draw distance to 50 percent - a value normally intended for cards with 1,024 MiByte VRAM. As our CPU benchmark review reveals, GTA 4 primarily needs a fast CPU.

To check the performance of the graphics cards we use our Promenade benchmark. It challenges the system with many passengers and heavy traffic as well as a huge range of visibility and is quite representative for GTA 4 because you spend a lot of time in the city.

Therefore we use a Quadcore Extreme QX6850 clocked to 3.33 GHz instead of the Core 2 Duo E8500 we usually use. The remaining components are a Intel chipset and 2x 2,048 MiByte DDR2-800 RAM and Windows Vista SP1.

286w ago - PlayFire, known for their custom gamer cards, has recently announced a major update to their PS3 trophy card system. They have expanded their selection to better suite the latest three new trophy patches that hit PlayStation 3 for the new games coming out with trophy support.

The update doesn't stop there! In addition to the new size and themes, PlayFire has introduced 'automated level calculation' based off the number & type of trophies you have fully integrated and functioning with a new level progress indicator so you no longer need to constantly adjust or guess your level.

Now, this all sounds cool, and much love to PlayFire for giving the PS3 users a custom gamer card solution, but seriously, when will Sony gives us real time syncing with a flash PSN gamer card? Adding every single trophy and game will get old fast.

All PS3 owners want, is a gamer card that will update in real time just like the XBox 360's. What is Sony waiting for? Could they be waiting to integrate the trophy reward system?

Or are they just not really worried about a very important thing that pimps out the PS3 in forums, Web sites, and social sites? For now, PlayFire will continue to be a good solution.
