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

Earlier this week in the launch-day Intel Xeon 6980P Granite Rapids review/benchmarks I unfortunately wasn't able to provide any CPU power consumption and performance-per-Watt benchmarks due a Linux kernel issue and the minimal time ahead of launch for testing. I've now repeated the Xeon 6980P benchmarking on the Linux 6.8 kernel of Ubuntu 24.04 LTS with power monitoring working and have those power efficiency numbers to share today for how Granite Rapids compares to prior Emerald Rapids / Sapphire Rapids / Ice Lake and against the current AMD EPYC Bergamo/Genoa(X) competition.
