Intel Unleashes 2.7x Performance per Rack Improvement for 5G Core

Intel Infrastructure Power Manager software delivers an additional 30%-plus power savings.

What’s New: To answer network operators’ demands for energy-efficient scaling, Intel Corporation disclosed two major updates to drive footprint, power and total cost of ownership (TCO) savings across 5G core networks: the preview of its Intel® Xeon® next-gen processors, code-named Sierra Forest, with up to 288 Efficient-cores (E-cores), and the commercial availability of the Intel® Infrastructure Power Manager (IPM) software for 5G core.

“Communication service providers require greater infrastructure efficiency as 5G core networks continue to build out. With the majority of 5G core networks deployed on Intel Xeon processors today, Intel is uniquely positioned to address these efficiency challenges. By introducing new Efficient-cores to our roadmap and with the commercial adoption of our Intel Infrastructure Power Manager software, service providers can slash TCO while achieving unmatched performance and power savings across their networks.”

–Alex Quach, Intel vice president and general manager of Wireline and Core Network Division

Why It Matters: Energy consumption and reduction of the infrastructure footprint remain top challenges that network operators face in building out their wireless 5G core network.

How It Works: Unveiled at Intel Innovation this past fall, the Intel Xeon processor roadmap is expanding to include E-core processors. E-cores will provide network operators with processors optimized for energy and TCO savings. Intel Xeon next-gen processors, code-named Sierra Forest, launching later this year will offer up to 288 cores and help operators recognize a 2.7x performance per rack1 improvement – an industry leading performance per rack for 5G Core workloads2.

The new processors will allow network operators to increase performance per rack, virtual CPUs (vCPUs) and performance per watt without significant changes to application software. Intel is collaborating closely with operators and 5G core software suppliers to deploy the new processors and Intel Infrastructure Power Manager software.

About CPU Innovations: Intel Xeon processors are the proven and most widely deployed server CPUs across the industry. Backed by an extensive ecosystem of innovative partners, Intel’s technological advancements and collaborations utilizing E-cores will help unleash proven power savings for a more sustainable future.

About Intel Infrastructure Power Manager: Launched last year at MWC 2023, the Intel Infrastructure Power Manager software for 5G core proved how operators can take advantage of the built-in telemetry of Intel Xeon processors and reduce CPU power usage without compromising key performance metrics including throughput, latency and packet drop. The software can be installed on existing and future Xeon-based network infrastructure.

About Reaching Net Zero Emissions: Energy consumption amounts to 20% to 40% of network operating expenses.4 It is critical for communication service providers (CoSPs) to holistically optimize end-to-end power utilization and the overall sustainability of their 5G networks. Integrating Intel Infrastructure Power Manager software into their 5G core software offerings allows operators to accelerate their sustainability goals and offset carbon dioxide emissions.

  • Casa Systems will feature a demo with Dell Technologies and Telenor in its booth in Hall 2, #2G11 at MWC showcasing up to 50% power savings with Intel Infrastructure Power Manager running on 4th Gen Intel® Xeon® processors. Casa's 5G core integrated with Intel IPM is now commercially available.
  • NEC ensures the energy efficiency of UPF by using Intel® Infrastructure Power Manager, enabling the offset of increasing power consumption for carbon neutrality. This achievement helps improve the performance of mobile network traffic processing by leaps and bounds, as well as contribute to lower power consumption and costs.
