Do Samsung Electronics and TSMC compete?

In this catalog they are both placed on 3 of the same parts, across 1 layer: Leading-edge foundry, 2.5D/3D advanced packaging, Interposers, silicon bridges, RDL. Sharing a part does not mean selling the same product to the same buyer, so read each row's product note.

Which has more placements, Samsung Electronics or TSMC?

Samsung Electronics has 10 placements and TSMC has 4. Placement counts reflect how thoroughly each company has been catalogued as well as its real breadth, so they are not a ranking.

Which shared parts are supply-constrained?

Leading-edge foundry, 2.5D/3D advanced packaging. These carry a sourced constraint tag on the parts page.

What the shared parts are

Leading-edge foundry — The advanced-node semiconductor fabs that manufacture the compute dies for essentially every AI accelerator on the market.
2.5D/3D advanced packaging — The 2.5D/3D processes that combine a compute die, HBM memory stacks, and a substrate into one finished package — the step that turns silicon into a shippable AI accelerator.
Interposers, silicon bridges, RDL — The silicon interposers, bridges, and redistribution layers that route signals between a compute die, HBM stacks, and the substrate inside an advanced package.
