From Tom's Hardware: The USB Implementers Forum now lists some of Intel's Core Ultra 400-series 'Nova Lake' platforms in its Integrators List, meaning that the products have passed applicable USB compliance and interoperability tests. The PCI-SIG Integrators List also includes Intel’s 900-series chipsets for Nova Lake-S processors. Such tests are conducted ahead of product launches to ensure interoperability and to gain the right to use the PCIe and USB logos on new products.
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 (which is not surprising, as the part is also supposed to support Thunderbolt 5). In contrast, Intel's desktop Nova Lake PCH-S chipset (Device ID 6E6E) is compliant with the USB 3.2 Gen2 standard and supports a data transfer rate of up to 20 Gbps, which is in line with unofficial information about Intel's 900-series chipsets. Meanwhile, the Integrators List lacks Intel's desktop Nova Lake processor that is expected to support USB4 (more on this later).
The choice of the products to certify first — a desktop chipset and a high-performance notebook CPU — may seem a bit odd. However, there is a good explanation for why Intel submitted these parts to the Integrators List ahead of others and why the order of such submissions for compliance testing does not matter significantly in this case.
