Yields are chip-specific anyway so you should really say Fermi's yields rather than TSMC's. e.g. I'm certain Cedar is yielding above 80% despite being 40nm. |
The 5-20% yield is in connection with the Fermi chip. It is rumoured that about 7 to 10 chips are fully functional per waver and another 10-20 chips could be functional with one cluster deactivated. The yield very likely isn't even close to 80% for dual-cluster-deactivated chips.
