Speed? No benchmark? We already have GPU enabled tools which are 20 to 30 times faster than CPU versions, I don't know what you are promising, but definitely your tool is not faster than others whatsoever, besides searching with CPU is useless.

You can benchmark it for yourself:
- run the fastest CPU tool you know and compare the keyrate with my tool!
On my slow CPU i get about 30% more speed, but this may be different on other CPUs. I would be happy if some users would post keyrates of their CPUs.

I never talked about GPUs and said that my tool can compete with them - of course GPUs are faster, but not everybody (like me) has access to a fast GPU, but some people here may have access to fast multicore CPUs and using several cores of a modern CPU could give in total a quite good rate, even if a GPU may still be faster. All i say is that my approach/logic for searching is different and that i took a big effort in improving speed for CPUs - that's it.

Solving #66 requires not only speed, it also requires luck and with luck even a slow CPU could solve #66 - unlikely, but possible - in the end it's more lotto than a puzzle Wink

So, if you have a fast GPU then you should use it and in this case my tool is of course not helpfull for you at all.
