OC Community,

Does anyone know the intricicies of the New P4 Prestonia, other than it's the Xeon to the new 478 pin Northwood P4's. I know it's going to have 512k full speed cache, but I've heard rumors of more.. Any info guys?

Sounds like a sweet CPU. This (http://news.cnet.com/news/0-1003-200-7230783.html?tag=mn_hd) article at CNet goes into a pretty good explaination of the Prestonia.

Here's the good stuff:

Prestonia will be made on the 130-nanometer process, which means the chip's basic features measure 130 nanometers. Foster, part of the Xeon generation of chips, is based on the 180-nanometer process. Smaller features mean more circuits can be squeezed on a chip, cutting down manufacturing costs while increasing performance and reducing power consumption. Prestonia chips will also be made with copper rather than aluminum wires.

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.
