<First order transistor performance is porportional to (Vin-Vt)*W/(Tox*Leff) if I remember correctly. At 1.6V I expect that Tox is already at or very near 0.18u value. If VCC at 0.18u is 1.5V then Vin-Vt is almost unchanged. Leff may come down a little but not much because the transistors were already so advanced at 0.25u. But W comes down to 0.18/0.25 = 0.72 which is the biggest change and it is in the numerator.

Process guys??????????>

KZ,

Vcc of 1.6V may have more to do with Athlon's architecture and its Alpha roots than with the transistor size on AMD's 0.25u. Remember that Alpha was running at some ridiculously low voltage on an old 0.35u process.
