Intel is to add two metal layers to some of its 130 nanometer
microprocessors. The processors concerned are the Xeons with 1MB and 2MB cache
and its Pentium 4 Extreme Edition starting in April. One also helpfully points

, relating to the 3.20GHz and the 3.40GHz Extreme Editions – which are
based on the server chip Gallatin core, as well as pointing to the Xeon sheet.

• The original and the alternate processes differ in the following: Original
0.13 micron process (6 interconnect metal layers) Alternate 0.13 micron process
(8 interconnect metal layers)
• Processors built on both 0.13 micron processes will implement the same CPUID
• There are no logic changes and no re-design of the circuits.
• The processors’ electrical, thermal and mechanical properties are equivalent
in form-fit-function.
