Intel processor numbers (model numbers) of desktop CPUs

This page lists processor numbers of all desktop Intel microprocessors. If you want to identify a processor number and cannot find it on this page then please see processor numbers of mobile CPUs page or use the tool on the right to identify the processor number.   

Intel processor number (model number) represents processor's relative performance within the same processor family. The processor number depends on processor's speed, front bus speed, L2 cache size, architecture and other processor features. The processors with larger numbers within the same family and within the same range have greater performance than processors with smaller numbers. Processor numbers cannot be used to compare CPUs from different families, even if the numbers reside in the same range. For example, Core 2 Duo E7xxx CPUs cannot be compared to Xeon E7xxx processors using processor numbers. Also, the numbers in different ranges cannot be used for performance comparison, even if the numbers belong to the same family. For example, processor (model) numbers cannot be used to compare Core 2 Duo E4xxx and Core 2 Duo E6xxx microprocessors. Even for processors within the same family and the range, the numbers can only tell which processor is faster or slower, but they cannot be used to tell how much faster or slower the processor is.

The first digit or letter and digit in the processor number identifies Intel processor family:

  • 3xx - Celeron D
  • 5xx - Pentium 4
  • 6xx - Pentium 4
  • 8xx - Pentium D and Pentium Extreme Edition
  • 9xx - Pentium D and Pentium Extreme Edition
  • 3xxx - Xeon
  • 5xxx - Xeon
  • 7xxx - Xeon
  • 9xxx - Itanium 2
  • E1xxx - Celeron Dual-Core
  • E2xxx - Pentium Dual-Core
  • E3xxx - Xeon
  • E4xxx - Core 2 Duo
  • E5xxx - Quad-core Xeon
  • E6xxx - Core 2 Duo
  • E7xxx - Core 2 Duo
  • E7xxx - Xeon MP
  • E8xxx - Core 2 Duo
  • Q6xxx - Core 2 Quad
  • Q9xxx - Core 2 Quad
  • QX6xxx - Core 2 Extreme
  • QX9xxx - Core 2 Extreme
  • QX9xxx - Xeon
  • X3xxx - Quad-core Xeon
  • X5xxx - Quad-core Xeon
  • X6xxx - Core 2 Extreme

I have Cel M 550 2GHz in my Acer Extensa 5220...Is it EM64T??

Response: I will add it this week.

Intel Processor FA80386EX25

Posted by: Anthony

I purchased Intel Processor from a broker and found out that there were two type of marking. One has the FA directly underneath the I386 marking while the other marking is right of that. Did Intel change the silkscreen marking in 2006? Please advise

Response: Sorry, I don't know this.
