SemiAnalysis Teardown: Intel 18A Matches TSMC N3E Density, Trails N2
Physical verification confirms Intel 18A logic density rivals TSMC N3E but lags behind N3P and N2, marking the shift from roadmap to shipped silicon.

Intel's 18A process node has achieved logic density comparable to TSMC's N3E, but does not yet lead TSMC's more advanced N3P or N2 nodes.
SemiAnalysis conducted a physical teardown of Panther Lake, Intel's latest consumer chip. It is the first commercial implementation of Backside Power Delivery Network (BSPDN) and Gate-All-Around (GAA) transistors. The teardown validates Intel's progress in advanced packaging (Foveros-S) and transistor architecture, confirming that compute cores use 18A while high-end GPU components still rely on TSMC N3E and I/O cores use TSMC N6.
Previously, market assessments relied heavily on Intel's roadmaps without physical verification. This analysis provides specific data on material choices and integration, confirming improvements in standard cell area and resistance control, while also highlighting the gap in peak density relative to Samsung SF2 and TSMC N2.
The teardown is paywalled content targeting semiconductor investors and technical experts. It offers no direct financial advice but provides key physical evidence for assessing the technical maturity of Intel's foundry business.
