Excellent low-voltage characteristics are just as important
on the high power end as the low. An unchanged socket level
power budget limitation limited Westmere-EX to gaining only
2 more cores and a one speed grade bump vs Nehalem-EX
from the 45 nm to 32 nm transition because of the limited
improvement in transistor IV characteristics and unchanged
threshold voltage in that process shrink. Improvements in
Intel's high end processors should be much more significant
going from 32 nm to 22 nm.
