..Ty for your explanation, I can't pm u back because of messaging limits. So basically there is no way to combine really fast random hex generator to work with the calculation process? So all we can do is randomly get starting points and from there work in increments.
True, according to my knowledge after 1 year of research.
In fact, you want a gpu BrainFlayer. Everyone wants it)
Ryan refuses to write it because he is a WhiteHat.
If successful, it will be slower than sequentially calculating points.

heuristic calculate the hashrate for BrainFlayer cuda/opencl
BrainFlayer cpu sse
0,1 Mk/s - 1core i7-6820
8core - 4core real, 4core hyper-threading, so x6 instead x8
0,6 Mk/s - 8core i7-6820
You'd probably need to perform string mangling on the GPU to keep the cores working as much as possible, because the transfer of each and every candidate phrase from CPU/system memory to the GPU could end up being a severe bottleneck. Perhaps a deliberately slower algorithm like warp may work better, since the GPU will spend most of its time calculating rather than transferring to/from the host... but how common are non SHA256 brainwallets? As you state, any passphrase based search (which is essentially a set of random keys) will be slower than a sequential search.
