For those wondering about Granite Rapids power use when idle or nearly idle with a single-threaded workload, the Python PyBench test had just a 185 Watt average and a peak of 206 Watts between the two Xeon 6980P processors -- much lower than many of the other tested Intel and AMD CPUs. Similarly, the Numpy CPU power consumption for one instance was around 209 Watts between the two Granite Rapids processors Meanwhile the Xeon Max processors were consuming around 320 Watts.

The Intel Xeon 6980P processors indeed consume more power than their predecessors but delivering higher performance. Typically the CPU power efficiency was comparable to AMD EPYC Genoa(X) or in HPC workloads and other cases where Granite Rapids and MRDIMMs are screaming, there was a nice power efficiency lead too. It will be very interesting to see where the upcoming AMD EPYC Turin processors fit into this performance and power efficiency equation.
