Thanks for the clarification. It's now clear that if the CUDA algorithm achieves its high speed by computing the delta from the previous key, then applying a filter would likely be ineffective. Even a 30% reduction in the range probably wouldn't offset the performance loss caused by filtering—assuming it's even possible to implement it. On standard CPUs, filtering might be slightly more reasonable, but their speed is vastly inferior compared to GPUs. Overall, even if filtering could be perfectly implemented on a GPU without any performance drop, a 30% reduction in the key space wouldn't make much of a difference for anyone without access to thousands of GPUs. The real benefit would come not from a 30% reduction, but from reducing the range by several orders of magnitude.
