Is password breaking accelerated on the GPU with an increase in videocard memory?
No, it will not be accelerated. The amount of videocard memory does not affect in any manner the speed of password breaking of passwords.
For password recovery on the GPU, the videocard memory (as well as the computer's main memory) is practically not used — of the entire multigigabyte array, only a few kilobytes or megabytes of memory participate.
Here, other characteristics of the GPU are more important — the core count of the videocard and their operating frequency. The product of these two dimensions is an indicator of GPU throughput for breaking passwords. The higher this figure, the better the GPU is for password recovery (without regard to the cost and power efficiency of the videocard).
For breaking passwords, you will find detailed information on AMD/NVIDIA videocard performance in a rating sheet on Passcovery's site..
Password recovery on the GPU
Videocards considerably increase (sometimes by factors of ten) the password search speed. The large number of computing kernels and high clock speed of operation are ideally suited for this task. Learn how to choose a videocard for password breaking and get the most for each dollar invested, here.
And that is what is even more important — the password recovery program.
Your new supercharged Porsche will hardly demonstrate everything that it is capable of, if Granny is behind the wheel. Same here. The program should not simply operate with the videocard, but squeeze everything out of it all to the last stroke.
This is why we recommend Passcovery Suite, a program ideally optimized for speed, which guarantees the best password search speed on any computer.
