Intel’s Nova Lake CPUs may be headed for TSMC’s N2P process, but early development reportedly began on Intel’s own 18A-P technology. New information suggests that Intel had already produced ES1 engineering samples of an 8+16 Nova Lake compute tile using 18A-P before shifting that design to TSMC’s more advanced N2P node.
The early Nova Lake sample reportedly featured 8 performance cores and 16 efficiency cores. More specifically, the chip used eight Coyote Cove P-cores and sixteen Arctic Wolf E-cores, making it a 24-core compute tile configuration aimed at early partner testing and platform development.
According to the latest claims, Intel designed the 8+16 Nova Lake compute tile for both 18A-P and TSMC N2P. However, the 18A-P version was not intended for a retail launch. Instead, it was reportedly created only for ES1 sampling because TSMC’s N2P process was not ready in time for Intel’s early Nova Lake validation schedule.
That timing appears to be the key reason behind Intel’s decision. Nova Lake development had to move forward, and partners needed early silicon to begin testing. Since N2P was on a later timeline, Intel used its in-house 18A-P node to get ES1 samples into the hands of vendors sooner.
The 18A-P-based Nova Lake samples were reportedly produced around April and May, while ES2 samples based on TSMC N2P followed later, around July and August. Qualification samples are said to already be available, suggesting that Nova Lake development is progressing toward its expected launch window.
One of the more interesting details is that the 18A-P compute tile reportedly included backside power delivery technology. This feature, often discussed as a major advantage of Intel’s advanced manufacturing roadmap, is designed to improve power efficiency and potentially allow better clock speeds by delivering power from the back side of the chip.
Even so, the 18A-P version was apparently only a temporary step. The final Nova Lake compute tile is now expected to use TSMC’s N2P process instead. The move may have been influenced by performance and density comparisons, with claims suggesting that Intel’s 18A-P implementation was not as suitable as the N2P version for this specific Nova Lake design.
In other words, Intel’s 18A-P node helped bridge a schedule gap, but it was not chosen as the production path for the 8+16 Nova Lake compute tile.
Nova Lake is expected to be a major generational shift for Intel’s desktop CPU lineup. The processors are anticipated to use the new LGA 1954 socket and could mark the beginning of a longer-lived platform. That would be welcome news for PC builders, especially after the shorter cycle of some recent Intel desktop platforms.
Intel’s current desktop roadmap has moved through several major architectures in recent years. Alder Lake introduced the hybrid P-core and E-core design to mainstream desktops, followed by Raptor Lake and Raptor Lake Refresh on the LGA 1700 platform. Arrow Lake then moved to the LGA 1851 socket with Core Ultra 200 branding and a chiplet-style design using external foundry technology for key tiles.
Nova Lake is expected to continue that tile-based strategy while bringing new CPU core architectures, including Coyote Cove performance cores and Arctic Wolf efficiency cores. The high-end desktop versions are rumored to scale up significantly, with some configurations expected to reach much higher core counts than Arrow Lake.
The broader roadmap may also include later CPU families for the LGA 1954 platform, potentially extending the socket beyond a single generation. Names such as Razor Lake and Hammer Lake have been associated with future Intel desktop plans, although many details remain uncertain.
There were also reportedly other consumer CPU projects evaluated across Intel 18A-P and TSMC N2-class technologies. One of those was said to be Beast Lake, a processor family that may have been considered for the LGA 1851 platform alongside another desktop project. Those plans were ultimately canceled, leaving Arrow Lake as the primary offering for the current socketed desktop generation.
If Nova Lake launches as expected, it could be one of Intel’s most important CPU families in years. The combination of a new socket, new core architectures, a more advanced manufacturing process, and higher core-count options may give Intel a stronger position in the desktop market.
For enthusiasts and system builders, the key takeaway is simple: Intel appears to have used 18A-P Nova Lake silicon to accelerate early testing, but the production compute tile has shifted to TSMC N2P. That decision suggests Intel is prioritizing the best available process for performance, density, and product readiness as it prepares its next major desktop CPU generation.
