In PC and embedded design, a processor's power consumption and heat output determine the size of the chassis and the cooling hardware it needs. The ideal CPU configuration differs depending on whether you are building a compact fanless device or leaving enough cooling headroom for higher performance. Now there are signs that Intel is developing two follow-ups to its low-power "Wildcat Lake" processors, which launched in the second quarter of 2026: one with even lower power consumption and one with stronger processing performance.
According to a post on X by hardware leaker Jaykihn on October 28, 2026, Intel is preparing an ultra-low-power processor called "Moon Lake (MNL)" and a higher-performance variant called "Wildcat Lake Refresh (WCL-R)." Moon Lake reportedly drops performance cores (P-cores) entirely and uses only low-power efficiency cores (LP-E cores), with a base power of 6W. Wildcat Lake Refresh, meanwhile, would double the P-cores from two to four and may support "Intel vPro," Intel's enterprise management platform.
However, neither product has been officially announced by Intel, and product names, launch timing, and final specifications are not confirmed. Because this information comes from unofficial leaks, it needs to be evaluated separately from the official specifications of products already on sale.
Intel's Low-Power Strategy Reportedly Splits: A P-Core-Free 6W Model and a Doubled-P-Core Model
The notable point of this leak is that Intel may be evolving its existing low-power processors in two different directions for different uses. Moon Lake would cut power consumption and heat by omitting P-cores, a configuration aimed at compact devices with limited cooling capacity. Wildcat Lake Refresh, on the other hand, would add P-cores to improve processing performance and reportedly strengthen the management features that corporate PCs require. Both target the low-power market, but they prioritize very different kinds of performance.
The benchmark for comparison is Wildcat Lake itself, which Intel has already brought to market. According to Intel's official product database (ARK), the series is classified as "Intel Core processors (Series 3)" and launched in the second quarter of 2026. The representative model, the "Intel Core 5 processor 320," has two P-cores and four LP-E cores and is manufactured on the Intel 18A process. Its processor base power is 15W, its maximum turbo power is 35W, and its minimum assured power is 10W.
By contrast, Moon Lake's base power is reportedly 6W. If realized, that would be well below the current Core 5 320's 15W base power. However, minimum assured power, base power, and maximum turbo power are indicators tied to different operating conditions, so the numbers alone cannot be used to compare actual power consumption or efficiency.

}Intel has long offered low-power products that use only efficient cores, such as Celeron, Pentium, and more recently the Intel Processor N series. Moon Lake could be positioned as a successor to those lines, but it is unclear whether it would be offered as part of the Core series or under a separate brand. The report that Intel is aiming for lower power settings than the existing Wildcat Lake suggests the company may be rethinking its lineup for small, low-power devices.
The current Core 5 320 combines the processing performance of P-cores under heavy load with the power efficiency of LP-E cores under light load. But in thin fanless devices or always-on embedded equipment in sealed, compact enclosures, thermal designs built around a 15W base power or 35W maximum turbo power can be difficult. Moon Lake appears to be an approach that simplifies the CPU configuration itself for such devices.
Wildcat Lake Refresh, by contrast, appears to be configured with general office work in mind, as well as environments that run multiple applications and background processes simultaneously. Corporate PCs often have security software and management agents running constantly, which calls for some CPU headroom. Doubling the P-cores from two to four could improve performance in these uses.
Moon Lake: Removing P-Cores Entirely and Targeting 6W Base Power
The biggest reported feature of Moon Lake is that it has no high-performance P-cores and is built only from up to four LP-E cores based on the "Darkmont" architecture. It omits the "Cougar Cove" P-cores used in the existing Wildcat Lake and relies on relatively small, efficient cores alone for CPU processing. This could reduce circuit scale and power consumption compared with configurations that include P-cores. Actual die area and power savings, however, depend on the design of the whole chip, including the GPU, NPU, cache, and peripheral circuitry.
Interestingly, it is reported that even without P-cores, the processor will not be integrated into a single silicon die. According to VideoCardz, Moon Lake retains the same multi-tile structure as Wildcat Lake, placing the four LP-E cores in a low-power island within the compute tile. In other words, it drops the performance-oriented P-cores while carrying over the functional partitioning used in the existing design.
A low-power island refers to a circuit region designed to keep processing going on relatively little power. If Moon Lake adopts the structure as reported, one can imagine a design in which light tasks run on the LP-E cores while the power states of other circuits are controlled as needed, reducing the chip's overall consumption. However, the specific power management mechanisms, and which circuits can be shut down under what conditions, have not been disclosed. For that reason, low-load power consumption and wake-from-sleep performance cannot be evaluated at this stage.
Jaykihn says the chip will be manufactured on Intel 18A and use the same BGA1516 package as the current Wildcat Lake. Intel 18A is a process already officially confirmed for the existing Core 5 320. A shared package specification may let Intel reuse existing manufacturing and assembly technology, but it does not guarantee motherboard compatibility. Reusing an existing board would require that the pins' electrical specifications, the voltage regulator module (VRM), the BIOS, and the firmware all support the new processor.
The 6W base power reported for Moon Lake also needs to be interpreted carefully. Club386 reports that Moon Lake's configurable power range is 6 to 15W. Again, this is leaked information, not a specification published by Intel. And a processor's power rating does not represent the power consumption of an entire laptop or embedded device.
In an actual system, memory, storage, the display, and wireless modules also consume power, and conversion losses in the power circuitry must be considered as well. Even if a processor's base power is 6W, the whole system will not run on 6W, and battery life cannot be simply calculated from that figure. Judging real power-saving performance requires measuring the power consumption of actual devices, both at idle and under heavy load.
The integrated GPU configuration has also not been confirmed. The current Wildcat Lake is reported to have two Xe cores based on the Xe3 architecture, but the specific GPU configuration for Moon Lake has not been disclosed. There is speculation that it could have one or two Xe3 cores to save power, but this is no more than conjecture. Additional information, including video playback acceleration, display output, and NPU specifications, will be needed to judge the product's overall capabilities.
There is also the question of manufacturing cost for an ultra-low-power processor built on Intel 18A. Adopting a leading-edge process may contribute to better power efficiency, but how manufacturing cost, yield, and packaging expense will affect the final price is unknown. If Moon Lake is aimed at low-priced PCs, profitability, including manufacturing cost, will matter as much as performance and power consumption.
Wildcat Lake Refresh: Double the P-Cores and Possibly Stronger Enterprise Management
While Moon Lake emphasizes power savings, Wildcat Lake Refresh is reported to build on the existing Wildcat Lake with stronger CPU processing power and enterprise features. It would raise the current maximum of two P-cores to four and pair them with four LP-E cores, for a CPU configuration of up to eight cores.
The table below compares the officially published specifications of the Core 5 320 with the configurations of Moon Lake and Wildcat Lake Refresh based on Jaykihn's leaks. The two unannounced products are marked as being at the reporting stage.

Note: The Core 5 320 figures are official specifications from Intel ARK. The two unannounced products are based on leaked information, and their specifications may change. Maximum turbo power, minimum assured power, and cTDP are different indicators and do not represent power consumption measured under the same conditions.
The Core 5 320, whose official specifications are public, has two P-cores and four LP-E cores and runs six cores and six threads in total. The P-cores' maximum turbo frequency is 4.60GHz, and the cache is 6MB. The integrated GPU has two Xe cores, the memory interface is single-channel, and PCI Express 4.0 is supported with up to six lanes. Both the CPU and GPU are manufactured on Intel 18A and housed in an FCBGA1516 package.
Wildcat Lake Refresh is reported to expand this configuration to up to 4P + 4LP-E. Doubling the P-cores could allow more compute resources to be allocated when several heavy tasks run at once. In environments that use many business applications, or on corporate PCs where security-related processing runs in the background, the extra P-cores could help performance.
However, doubling the P-cores does not necessarily raise real multithreaded performance by the same proportion. If the CPU's overall power limit does not change, the power available to each core is constrained, and clock speeds may fall. Actual performance depends on base and turbo clocks, power limits, cooling capacity, and the applications being run. More cores mean greater potential processing capability, but measured data is needed to judge how much performance actually improves.
Another point of interest is Intel vPro support. According to Intel ARK, the current Core 5 320 does not support Intel Active Management Technology (AMT) or the Intel Stable IT Platform Program (SIPP). It does support Intel Standard Manageability, however, so it is not entirely without enterprise management features. If Wildcat Lake Refresh gains vPro support, it could open up management features and enterprise platform options that were unavailable with the existing product.
AMT enables functions such as remote management that does not depend on the OS state on supported systems, while SIPP is an initiative concerning platform stability for corporate PCs. Such features matter to IT departments that manage many PCs centrally. However, vPro comes in several product tiers, and which features are available depends not only on the CPU but on the configuration of the whole platform. Which vPro features Wildcat Lake Refresh would offer, and whether all SKUs would support them, will have to be confirmed in an official Intel announcement.
As for branding, information reported by VideoCardz in June 2026 suggested that Wildcat Lake Refresh could be sold as Core 5 and Core 7 in Core Series 4. The latest information can be seen as adding details on power settings and enterprise management features to the previously reported 4P + 4LP-E configuration. The Core Series 4 brand name, however, has also not been officially announced by Intel.
As for the integrated GPU, Wildcat Lake Refresh is reported to carry up to two Xe3 cores, as in the current product. If the GPU scale does not change, a graphics performance gain as large as the increase in CPU cores is unlikely. Still, real performance varies with GPU clock speed, power allocation, and memory bandwidth, so the performance gap cannot be asserted at this point.
Markets Moon Lake and Wildcat Lake Refresh Target, and What to Watch
If the leaks are accurate, Intel would build its lineup around the existing Wildcat Lake, adding the even lower-power Moon Lake and the performance-boosted Wildcat Lake Refresh. Rather than simply raising CPU clock speeds, this can be read as a strategy of changing the number of P-cores itself to meet different power and performance requirements. But Intel has not officially explained either the products' specifications or which markets they actually target.
Possible uses for Moon Lake include fanless compact laptops, NAS devices for homes and small offices, and industrial edge computing terminals. In such devices, stable operation within limited power and cooling capacity can matter more than peak CPU performance. In sealed industrial equipment especially, dissipating internal heat efficiently is a key design challenge. These are, however, uses one can imagine from the reported specifications; no PC or device makers have been confirmed as adopting the chip.
Even if the 6W base power spec materializes, a fanless design is not necessarily possible. Whether cooling hardware is needed depends not only on the CPU's heat output but on heat sink surface area, the material and thermal conductivity of the enclosure, ambient temperature, and internal airflow. Even with a low base power, designers must account for power draw during momentary heavy loads and the temperature rise from long continuous operation. Until thermal design data from actual devices emerges, no firm assessment of fanless operation or quietness can be made.
Wildcat Lake Refresh, on the other hand, could suit the market for buyers who want enterprise management features while balancing low power consumption with a degree of processing performance. More P-cores could improve performance when running multiple applications at once or handling relatively heavy business workloads, and vPro support could affect corporate PC procurement plans. Actual performance and the availability of management features, however, will depend on the final SKU lineup and the specifications of the systems that use them.
If benchmark results from prototypes or unannounced products appear, the measurement conditions will deserve attention. Fairly comparing CPU performance and power efficiency requires checking memory speed and channel configuration, cooling capacity, power limits, firmware versions, and workloads. With low-power processors in particular, clock speeds and performance can differ greatly between short bursts of heavy load and prolonged continuous processing. What matters is not just a benchmark score but how much power it takes to sustain that performance.
For anyone considering adoption, the first thing to check is an official Intel announcement. Specifically, product registration on ARK would confirm the core configuration, clock speeds, power specifications, GPU and NPU configuration, and package details. Once the product branding, SKU lineup, extent of vPro support, and launch timing are clear, the differences from the existing Wildcat Lake and other Intel products can be evaluated concretely.
Competitors are also worth watching. With efficient Arm-based SoCs gaining presence in the mobile PC market, strengthening its competitiveness in the low-power segment is an important issue for Intel. If Moon Lake adopts the 6W design as reported, it could become a new x86 processor option for devices that prioritize low power consumption. Wildcat Lake Refresh, for its part, appears aimed at strengthening Intel's competitiveness in the business PC market by combining processing performance with enterprise management features.
As of now, neither Moon Lake nor Wildcat Lake Refresh has been confirmed as an official product plan. The idea of a 6W model with no P-cores and an enterprise model with doubled P-cores is an interesting one for considering where Intel's low-power processors are headed, but their real value will depend on final specifications, performance, power consumption, and price. Beyond Intel's official announcements, the focus will be on how well real devices can balance power efficiency and processing performance.
