The latest roadmap leak indicates that Intel Nova Lake will be available on desktops under the Intel Core Ultra 400 name, skipping the Core Ultra 300 desktop numbering. The X post from leaker momomo_us places Nova Lake in 2027, but this is unconfirmed and should be treated as a rumor.
The mock roadmap, posted on X, suggests that the Core Ultra 300 name will be used for Panther Lake on mobile in the first half of 2026, while Arrow Lake and any refreshes will retain the Core Ultra 200-series numbering on desktop. That would mean a direct desktop jump to the 400-series for Nova Lake instead of using 300 on desktop.
Who wouldn’t be curious about a naming skip like that? It feels like a bit of a surprise, but remember that the leak is just one post and not an official Intel announcement.

The roadmap also shows the Arrow Lake period extending into late 2026, which fits the idea that Arrow Lake Refresh chips would remain in the 200-series. Early shipping records reportedly show a 28-core Nova Lake pre-QS sample moving for testing, but there’s usually a long gap between early testing and full production.
Additionally, earlier leaks have hinted at an Intel 3D V-cache style approach for Nova Lake, which could provide significantly larger L3 caches on some chips, potentially even multiples of the current X3D parts, although these reports remain unverified. If you’re considering upgrades now, remember that test samples don’t necessarily mean retail parts are ready, and it’s perfectly fine to shop for motherboards and coolers that match your current build.
