Intel Xeon 6980P vs. AMD EPYC Power Efficiency / Performance-Per-Watt Benchmarks

In many of the benchmarks as shown on Tuesday the Granite Rapids performance is leading while now with the CPU power numbers collected we see its power efficiency is typically comparable to Genoa(X). It is a big improvement though compared to Emerald Rapids and prior generation Xeon Scalable processors.

In the HPC workloads where the Xeon 6980P + MRDIMMs is a pretty sweet combination, the Granite Rapids performance-per-Watt does deliver leading performance. For those wondering about MRDIMM power consumption, that will come in the DDR5-6400 vs. MRDIMM-8800 comparison.

With the very demanding WRF weather research and forecasting model benchmark, the dual Xeon 6980P was consuming 995 Watts on average -- just below the default 500 Watt TDP rating for both processos.
