TSMC reportedly lags behind Samsung Foundry in 3 nm yields

[Redaktion]

A new report says TSMC's 3 nm node has yields of just 55%. On the other hand, Samsung Foundry is faring much better at 60%. AMD is rumoured to use Samsung Foundry for some of its upcoming parts.

55-60% is a ~9% gap, not a lot...and TSMC's probably could be pushed to higher clocks with less leakage, as usual.

3nm, really? The last true nm metrics should be used for Intel 10nm, later named Intel 7. TSMC, Samsung since "10" part name in their products has unknown nm value. A bit closer to reality would be number of transistors per mm^2. TSMC 3 is probably quite different than Samsung 3. Just guess Samsung 3nm == TSMC 5nm == Intel 7nm (Intel 4).

Beating a dead horse, but those numbers seem about right.
