Intel 5th Gen Xeon Performance Benchmarks: Impressive Efficiency Gains With "Optimized Power Mode"

([Processors] 18 December 10:00 AM EST 18 Comments)

With the new Intel 5th Gen Xeon "Emerald Rapids" processors there is a new feature called the Optimized Power Mode (OPM). This Optimized Power Mode can be enabled via the system BIOS for Emerald Rapids for helping to reduce the CPU power consumption when not running at full utilization. With Intel claiming that up to 110 Watts of server power savings can be conserved when running at 30~40% utilization, I was curious and set out to run my own Optimized Power Mode benchmarks with the Xeon Platinum 8592+ processors. Here is a deep dive on Intel Optimized Power Mode benchmarks.
