Intel Nova Lake Platforms Pass USB and PCIe Compliance Testing

Compliance Achieved for Nova Lake Platforms

Intel's Core Ultra 400-series 'Nova Lake' platforms have successfully completed compliance testing with industry standards. Specific Nova Lake components are now listed on the USB Implementers Forum (USB-IF) Integrators List and the PCI-SIG Integrators List. This is a standard procedure for new hardware to ensure interoperability and to gain authorization for using the respective USB and PCIe logos on products.

USB Compliance Details

The USB-IF listing confirms that Intel's mobile Nova Lake-H processor (Device ID D331, D333) is compliant with the USB4 80 Gbps specification. In contrast, Intel's desktop Nova Lake PCH-S chipset (Device ID 6E6E) is compliant with the USB 3.2 Gen2 standard, supporting data transfer rates up to 20 Gbps. The Integrators List currently does not include Intel's desktop Nova Lake processor, which is expected to support USB4.

PCIe Compliance for Desktop Chipsets

The PCI-SIG Integrators List includes Intel’s 900-series chipsets, which are designed for Nova Lake-S processors. This indicates that these chipsets meet the necessary PCIe standards for their upcoming release.

Qualification by Similarity

Intel utilizes the USB-IF's Qualification by Similarity (QbS) program. This program allows for related products to be certified with limited or no additional testing once a sufficiently similar product has passed compliance. This explains why Intel might submit specific CPUs and chipsets first, as their USB4 and USB 3.2 circuitry is similar across different Nova Lake products, enabling subsequent certifications through QbS.
