Keysight and AMD Break Barriers to Redefine Benchmarking for Cloud and Edge Infrastructure Performance

04/10/2026

Keysight Technologies, Inc. leveraged 4th generation AMD EPYC™ CPUs from Advanced Micro Devices, Inc. to develop an industry first benchmarking methodology that redefines the landscape of system performance evaluation for high-speed digital designers, network equipment manufacturers, and data center operators.

The deployment of mobile and 5G private networks is expected to grow rapidly across many industries as part of their automation and digital transformation strategy. This diverse set of industry use cases requires a versatile compute architecture that can simultaneously support millions of low-latency, high-bandwidth devices, and a multifaceted workload profile. Given this transformation, comprehensive infrastructure benchmarking is critical to ensure optimal performance across a spectrum of industry use cases.

To provide more realistic performance benchmarks, Keysight in collaboration with AMD developed an integrated test case methodology that takes into account the processing power of central processing units (CPUs). Using realistic traffic emulation, this novel approach enables data center operators to extract more performance from a chosen CPU and to characterize the performance across multiple vectors while adhering to bandwidth requirements. The methodology was developed by deploying Keysight's software tools onto AMD EPYC™ processors to conduct staged test cases with realistic traffic at scale.

Highlights of the test case methodology include:

• Infrastructure scalability – In settings such as smart grids and smart manufacturing, smooth and reliable operation requires handling millions of concurrent devices. Traditional benchmarks frequently overlook the CPU's capacity and its capability to handle a considerably higher concurrent load as the network's bandwidth constraints obscure this ability. This new benchmarking approach is designed to uncover the true CPU power and scalability in these environments.
• Real-life authenticity – Mobile and 5G private networks support specialized fields like vision-based smart manufacturing, extended reality (XR) viewership, and retail workflows. Testing infrastructure for its capability to handle realistic application, voice, and video traffic is crucial. The new benchmark emphasizes replicating bulk activities with millions of devices establishing new sessions and including highly realistic scenarios like subscribers initiating voice, video, and web calls. This insight into
  real-world capabilities empowers data center operators to provision their
  infrastructures accurately.
