Moscow (Russia) – HotHardware has a mini-review up of a software program which is showing how phenomenally powerful the GPU-acceleration can be to defeating encryption or security.
ElcomSoft’s Wireless Security Auditor 1.0 can operate with or without GPU acceleration, and it supports both Nvidia and ATI graphics cards.
To put the power in perspective, a Core 2 Quad Q6600 is capable of trying 1100 passwords per second. A Core 2 Duo E4500 is capable of 480 password per second. Nvidia’s GTX 280 increases that number to 11,800 per second (10.7x faster than Core 2 Quad). ATI’s HD 4870 increases it to 15,750 per second (14.3x faster), and their HD 4870 X2 increases to 31,500 per second (28.6x faster). Nvidia’s high-end Tesla S1070 increases it the furthest, to 52,400 passwords tried per second (47.6x faster).
If it were to tak 12 million tries to reach the correct password, the Tesla card would complete the task in 3.8 minutes. The Core 2 Quad system would require over three hours (181.8 minutes) while the Core 2 Duo would take nearly 7 hours. I have a feeling my notebook computer would take days.
In some applications, the parallel computing power of GPU is flatly astounding. To own this wonderful ability you’ll pay $1,199 – though the software is currently on sale for half price ($599.50) until March 1, 2009.
