GPU vs CPU performance

[KT819GM]

Seems it's always some weird results from The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) users. I can go on full speed @2xHD6990 on weak AMD E350 APU. But it's on ubuntu with properly installed drivers. And also you are not using any rules, just single dictionary which should be not a problem for your cpu.
