Yes, they matter, and they should probably be included. Ditto for GPU driver version and OpenCL backend version. For NVIDIA GPUs, you'd include things like these: Driver Version: 418.39 CUDA Version: 10.1 as printed by nvidia-smi. > so we could start with same hashes as CPU tables have.. I think that choice is not ideal. We'd also need to add sha*-crypt to all tables, whereas our LM is in a poor state on CPU (doesn't scale to many threads, except with "--fork") and our bcrypt-opencl is in a poor state on NVIDIA GPUs. However, if you want to show JtR shortcomings along with CPU/GPU differences, then these are fine, they just should not be misinterpreted as indicating the CPUs and GPUs can only achieve roughly those speeds at these two hash types.
