Go here to read about it. Here's a little tid bit.
The switch in manufacturing allows Intel to improve other architectural features of Prestonia as well. The chip will come with 512KB of integrated secondary cache, a reservoir of memory that stores data for quick access. The canceled chip, part of the Foster generation, would have had 256KB of secondary cache. Increasing the size of the cache typically improves performance. Both Foster and Prestonia are based on the Pentium 4 core.
Sweetness!!
