Hello all,
So let me start off by saying that I'm well aware that the amount of GPU memory is essentially meaningless when it comes to performance - this is not yet another of those threads!
That said, are there any implications of memory size one should consider when purchasing a modern card (say 3GB vs 6GB). From my understanding from other threads the memory does dictate how large / how many rules,hashes,dictionaries/masks/etc... one can load. Have memory sizes increased to the point where that no longer realistically matters, or are there still edge cases where it could be an issue?
Finally, how does memory size scale with multiple cards? If I have 4 3GB cards do I have 12 GB of global memory to work with or is there some bottleneck where we limited to the lowest amount of memory on a single card or something?
Thanks!
