Logic Density (may be inaccurate, also it's not the only metric for performance ): Raipidus 2nm ≈ TSMC N2 > TSMC N3B > TSMC N3E/P > Intel 18A ≈ Samaung 3GAP

But 18A/20A already has PowerVia, while TSMC will implement Backside Power Delivery in A16 (next generation of N2)

So 18A is roughly TSMC N4P. N4P is part of the N5 family.

18a supposedly has some advantages in power efficiency and some other areas compared to TSMCs approach. Ultimately, TSMC doesn’t have a 2nm product yet, so it is a pretty big deal Intel is competitive again with TSMC latest. Samsung is incredibly far behind at this point.
