The USB-IF, the organization responsible for maintaining USB standards, has certified several new device IDs. Specifically, it has confirmed that two Nova Lake-H device IDs, designated D331 and D333, comply with the USB4 standard. In addition, the Nova Lake PCH-S chipset—intended for desktop motherboards and listed under ID 6E6E—has passed the USB 3.2 Gen 2 conformance test.

Industry analyses suggest that Intel has applied a method known as “Qualification by Similarity” at this stage. By certifying a laptop CPU and a desktop chipset, Intel can obtain certification for a broader range of related products without having to subject every single variant to the full testing process. This strategy is often used to keep the exact specifications of flagship desktop components under wraps until shortly before the official market launch.

PCIe 5.0 and Root Complex Verification

In parallel with the USB tests, Intel has made significant progress with the PCI-SIG. The 900-series chipset has been listed in the conformance databases since April, with entries in the ID range from 6E30 to 6E47. In August, however, a new set of entries appeared that are specifically intended for processors. The device IDs D461, D465, and D467–D46A were verified for the PCIe 5.0 x16 Root Complex. It is believed that these IDs correspond to the Nova Lake-S desktop processors or high-end variants for mobile devices. Since conformance testing is typically the final technical hurdle before a product is released for mass production, these entries suggest that the architecture is functionally complete.

Production Timeline and Core Specifications

According to recent reports, mass production of Nova Lake-S components is set to begin in the fourth quarter of 2026. Following this production phase, the first retail SKUs are expected to hit the market in the first quarter of 2027. The initial Nova Lake-S launch is expected to feature a 28-core configuration with a single compute die. Although a higher-end flagship version with 52 cores has been mentioned, the specific technical details for this SKU have not yet been finalized. Intel has indicated that this high-core-count version will be released for the desktop market sometime in 2027.
