The best targets are stuff that is data dependant for behavior and memory size for current gpus. Larger number sizes will help but maybe not as much as you think, since those work well for FPGA or asic devices. Data dependency helps because it can kill cache behavior and branch prediction which are key features for fast speed on fpga and gpu devices. Combined with memory size which limits the number of possible attempts on devices thats where the protection comes from. N.B. sorry for typos, have a cat in the way
