Intel Nova Lake leak points to Core Ultra Series 400 branding, staggered release next year — hotly anticipated flagship 52-core desktop CPU might not arrive until late 2027

Intel was expected to unveil its next-generation desktop processors later this year. The upcoming Nova Lake lineup has been making the rounds online, and a new report from VideoCardz suggests that Intel could introduce it under the Core Ultra Series 400 branding. For context, the current Arrow Lake and Arrow Lake Refresh desktop CPUs follow the Core Ultra Series 200 naming scheme, while Intel’s latest Panther Lake mobile processors carry the Core Ultra Series 300 branding.

The report also claims to reveal the review embargo windows and launch timeline for several Nova Lake models. According to the report, Intel will initially introduce a 28-core DS package, which is expected to launch between January and March 2027. The new DS suffix is said to be an internal package designation for processors featuring dual-compute tiles. This will reportedly be followed by 28-core K-series (unlocked) models between March and April 2027, while 16-core and 8-core variants are expected to arrive between late March and May 2027. The flagship 52-core DS model is reportedly scheduled for a much later launch, potentially between late May and September 2027.

While Intel is yet to officially confirm a launch date for Nova Lake, various leaks have suggested that the lineup could be one of the company’s biggest generational leaps in recent years. The flagship desktop SKU, featuring a 52-core configuration, is expected to combine 16 Coyote Cove Performance (P) cores, 32 Arctic Wolf Efficiency (E) cores, and four Low Power Efficiency (LPE) cores. This would be a notable jump over the current Core Ultra 9 285K, which features a total of 24-cores. The introduction of Coyote Cove and Arctic Wolf also points to an entirely new CPU architecture, replacing the Lion Cove and Skymont cores found in Arrow Lake.

Nova Lake is also rumored to bring new platform upgrades including support for DDR5-8000 memory, up to 24 PCIe 5.0 lanes for expansion, Thunderbolt 5, and Intel’s next-generation Xe3 Celestial integrated graphics. The processors are also expected to feature an upgraded NPU5 for AI workloads along with a 150W Processor Base Power (PBP) and 253W Maximum Turbo Power (MTP) on the flagship model, despite the substantial increase in core count. Earlier reports have also indicated that Nova Lake will transition to a new LGA1954 socket, meaning users will likely need a new motherboard to upgrade from the existing Arrow Lake platform.
