Power savings data revealed in NTT DATA's processor efficiency tests

NTT DATA Group tested power efficiency on Intel's latest Xeon processors as part of their sustainability initiatives and NET-ZERO Vision 2040, aiming for net-zero emissions by 2040.

Key findings from testing Java-based web applications include:

• 5th Gen Intel Xeon Scalable processors with OPM 2.0 cut power use by 7% (25.1W) under low-load
• Intel Xeon 6 processors with E-cores showed 41-51% lower power use than 5th Gen
• Performance per watt nearly doubled with E-core processors without losing application performance

NTT DATA plans to apply these findings, recommending E-core processors for sustainability projects.
