Hello. I've limited WUs to GPU only and it seems GPU gets less load compared to GPU+CPU mode. Besides, GPU only WUs need much longer time to be crunched comparing to GPU+CPU mode. Does it ruin performance running GPU only mode? Is CPU essential for crunching WUs? GPUs are AMD Vega 56 + RX 480. CPU i5-4670 Thanks. |

Hello. It's more efficient to let the gpu use a cpu core to run the workunits, you need to keep the gpu fed and happy as it does 10 times the work giving you10 times the credit as a cpu core. The cpu and gpu workunits are doing the same thing just in different ways, so do things efficiently. |
