Process node
The semiconductor manufacturing generation used to fabricate a chip. Smaller nominal numbers (3nm, 2nm) generally mean better power efficiency and density — but the marketing names no longer map to physical gate length.
Process node names (TSMC N3, Samsung 3GAP, Intel 18A) once corresponded to a feature size in nanometers. Now they are marketing labels — each foundry uses its own naming logic.
Rough equivalencies (2026)
- TSMC N3 / N3E — Apple M5, Snapdragon 8 Elite, Ryzen 9000.
- TSMC N2 — Apple M6 expected, server first.
- Samsung 3GAP — Exynos, Tensor.
- Intel 18A — Panther Lake; competitive with TSMC N3.
Why it matters
A newer node lets the same chip run faster, cooler, or with more cores in the same power budget. Real-world impact: 15–25% perf/watt improvement per generation — significant for laptops and phones, modest for desktops.
The marketing names lie; transistor density figures (MTr/mm²) are the honest comparison.
How to use Process node in a real comparison
The semiconductor manufacturing generation used to fabricate a chip. Smaller nominal numbers (3nm, 2nm) generally mean better power efficiency and density — but the marketing names no longer map to physical gate length. In practice, this is most useful as one part of a decision rather than a standalone quality badge. Compare it alongside the workload, room, ecosystem, budget, and ownership constraints that apply to you; the strongest published figure is not automatically the best outcome for every buyer.
What to check next
Open a product page and check the stated value, configuration, price, and related trade-offs before treating this term as decisive. It is especially relevant in .
Avoid the one-number trap
Manufacturers can describe the same capability under different conditions. Compare like-for-like variants, check the unit and test condition where available, and use a head-to-head page to see whether a measurable difference is material for your own use.
vsMars presents structured catalog values to make trade-offs legible. The linked product and spec pages are the right place to inspect the underlying values before buying.
