Keysight Technologies has collaborated with AMD to validate electrical compliance for PCI Express (PCIe) at speeds up to 64 GT/s for pre-production AMD server CPUs. Using Keysight’s early access PCIe CEM test tools, including beta software, AMD tested and developed a server motherboard capable of supporting PCIe 6.0. The technology was showcased at the PCI-SIG Developer’s Conference held June 11–12 in Santa Clara, California.
PCIe 6.0, the latest high-speed interface for server and computer components, achieves data transfer rates of up to 256 GB/s across 16 lanes. It offers lower latency and improved energy efficiency compared to PCIe 5.0, supporting the demands of artificial intelligence (AI) accelerators and 802.3dj Ethernet communications. These enhancements facilitate faster and more efficient AI application development and networking deployments.
Keysight provided AMD with its 64 GBaud High Performance BERT, 59 GHz UXR-Series Oscilloscope, and pre-compliance software to characterize, tune, and validate the server platform. This early access to pre-release beta code ensured the hardware met performance requirements before official industry test tools were available.
Amit Goel, Corporate Vice President of Server Engineering at AMD, noted that Keysight’s tools enabled AMD to confirm electrical compliance at 64 GT/s, validating the signal integrity and electrical robustness of its upcoming server CPUs. Dr. Joachim Peerlings, Vice President and General Manager of Keysight Network and Data Center Solutions, highlighted the collaboration’s role in advancing PCIe 6.0, emphasizing its importance for AI and networking applications.
The PCIe test setup was demonstrated live at the PCI-SIG Developers Conference 2025 at the Santa Clara Convention Center.
