"AMD had another ace up its sleeve when designing Thuban. The folks at GlobalFoundries have made tweaks to their 45-nm silicon-on-insulator process, adding a low-k dielectric layer to reduce leakage power. The result? Within a given thermal envelope, AMD can achieve nearly the same clock speeds with six cores as a Phenom II X4 did with four cores."

Ich meine, dann könnte man die Taktschraube wahrscheinlich nochmals 20% anziehen, bei selber TDP.
