Intel has launched a wide range of new Pentium 4 chips, starting with the 630 at 3GHz, the 640 at 3.2GHz, the 650 at 3.4GHz and finally the 660 at 3.6GHz. All these processors will operate at an 800MHz bus speed and have 2MB of level 2 cache memory.

The top of the range chip will be the new Extreme Edition which operates at 3.73GHz and has a 1066MHz bus. The new Extreme Edition differs not only by supporting 64-bit operating systems, but also with its cache size, which has actually been reduced in total by 512KB.
