What the leak says
Hardware leaker Jaykihn, answering a question on X, said Wildcat Lake Refresh is expected in Q2 2027 and Moon Lake is targeting Q4 2027. Notebookcheck reported the same claims independently of Digital Trends, which is useful corroboration of what the leaker said. It is not confirmation from Intel.
The catch is that the later chip is not the faster one. Moon Lake launches later but may not be more powerful, because Intel appears to be designing the two for very different kinds of laptops.
Moon Lake: the low-power chip
- Target: Affordable, low-power laptops, including devices that don't need cooling fans.
- Cores: Four Darkmont low-power efficiency cores, built on Intel's 18A process, with a base power rating of 6W. The leak describes no traditional performance cores.
- Possible positioning: Moon Lake is expected to succeed Twin Lake. One outlet's report adds claims about sub-$400 notebooks and a configurable limit near 15W. That is a single secondary report, so treat it with extra caution.
A 6W rating is a design target. It doesn't tell you battery life, surface temperature or real-world speed. Those depend on the laptop maker's cooling, battery, firmware and power settings. As TweakTown puts it, the leak doesn't establish actual system power consumption. No benchmarks, prices or laptop partners have surfaced.
Wildcat Lake Refresh: more cores
- Cores: Up to four performance cores plus four low-power efficiency cores. The leak describes no standard efficiency cores. Wildcat Lake Refresh may use a 4+0+4 layout: four performance cores, no standard efficiency cores and four low-power efficiency cores.
- Power and business features: Intel vPro support and configurable limits reaching 35W. One outlet puts the range at 10–35W, with vPro aimed at commercial fleets.
- Branding rumor: VideoCardz claims it is a Core Series 4 product aimed at the Core 5 and Core 7 tiers, with Core 3 staying a non-refresh. This is unconfirmed.
Intel's own datasheet for the current Core Processor (Series 3), "formerly known as Wildcat Lake," lists up to two P-cores, no E-cores and up to four LP E-cores. Four P-cores would double the maximum P-core count in that listed configuration. That does not mean double the performance. Clock speeds, power limits and cooling matter just as much. Reporting also says the refresh would keep Cougar Cove performance cores and up to two Xe3 GPU cores. If that holds, the gain would come from core count rather than a new architecture.
What Intel has confirmed about the process
The leak says Wildcat Lake Refresh would use Intel's improved 18A-P process for its compute tile, while Moon Lake sticks with standard 18A.
Intel has confirmed some things about 18A-P in general. A June 16, 2026 announcement said 18A-P had entered risk production. Intel claims it delivers 9% higher performance at the same power, or 18% lower power at the same performance, compared with 18A. Intel also says it is design-rule compatible with 18A.
These are process-level claims from Intel. They are not measurements of either rumored chip. Intel's announcement also doesn't confirm that either product will use 18A-P or ship on the leaked schedule.
What it means if you buy a PC
Digital Trends' naming complaint is fair. Digital Trends also notes the wider roadmap chatter:
- Nova Lake for desktops and high-end laptops, with Nova Lake-HX rumored under Core Ultra 4000-series branding.
- Razor Lake-AX, an integrated-graphics project whose consumer-laptop future is unclear.
- A possible return of Raptor Lake-HX under Core 2000 HX branding.
All of these are leaks too. Here is how I'd handle shopping while the names are this unsettled:
- Ignore codenames and launch order. Look at the exact processor model and its core configuration.
- Check the power limit the laptop maker actually set. The same chip can behave very differently in a thin fanless design and in a roomier chassis.
- For business fleets, check vPro availability on the specific model, not the chip family.
- Wait for independent laptop reviews before trusting any leaked efficiency or performance claim.
Bottom line
Based on the leaks, Moon Lake looks like a cheap, efficient chip for basic laptops, and Wildcat Lake Refresh looks like a modest step up in core count for mainstream and business machines. The schedules, core counts and branding could all change before launch. A newer-sounding name still doesn't guarantee newer technology.
