Intel revealed today that 45nm Penryn clocked above 3GHz, a higher FSB, new
SSE4 and delivers more IPC than the current 65nm Merom. Micro-tweaks that reduce
CPU latency on the Penryn includes a faster divider technique called Radix-16
divider that enables 4 bits per cycle compared to 2 bits on the Merom and a
shuffle engine that can perform 128-bit ops in a cycle.

Power savings features includes a new power state during idle called Deep
Power Down Technology that allows core voltage to drop significantly and L1/L2
caches to be turned off completely. Performance improvement on single-threaded
apps through Enhanced Intel Dynamic Acceleration Technology that allows one core
to sleep while the other core gets a frequency boost.

Comparing quad core of the current generation which is Kentsfield against
quad core of the next generation which is Yorkfield, Intel claims that Yorkfield
will be up to 45% faster than Kentsfield in bandwidth intensive applications.
Yorkfield has 1600MHz FSB and 2x6MB of L2 cache comparing to 1333MHz FSB and
2x4MB of L2 on the Kentsfield. When comparing dual core Conroe to dual core
Wolfdale, the latter will deliver up to 20% increase in performance in the
current games.
