Benchmarking AMD's BC-250, offering Steam Machine-like performance at half the price
AMD splits Zen 7 into three EPYC families for 2028 and starts selling server CPUs by the agent
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.
The USB-IF has a program called Qualification by Similarity (QbS) for sufficiently similar products, under which testing one product can enable related products to be certified and added to the Integrators List with limited or no additional compliance testing. Since USB4 and USB 3.2 circuitry in different Nova Lake products is similar, Intel can submit select CPUs and chipsets for USB-IF compliance tests and then follow up with the QbS.
Meanwhile, since USB-IF certification is formally attached to a specific product name, model, and revision, differently named products are not certified automatically simply because they contain identical USB circuitry. These products must be submitted separately under QbS, after which USB-IF decides whether the differences are significant enough to require additional testing.
