I guess these could be important: % clinfo | grep -e 'Platform Version' -e 'Device Name' -e 'Driver Version' -e 'Max compute units' -e 'Max clock frequency' Platform Version OpenCL 1.2 CUDA 11.2.162 Device Name GeForce GT 1030 Driver Version 460.91.03 Max compute units 3 Max clock frequency 1430MHz >> so we could start with same hashes as CPU tables have.. > >I think that choice is not ideal.
