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.

Older Intel families, like Pentium 4 or Celeron D, used numerical processors numbers. The first digit in this number signified processor family, and remaining digits represented relative CPU performance. Newer processors families, starting from Core 2 Duo, in addition to a number also used one letter prefix that indicated processor's maximum power consumption:

E - from 50 to 74 Watt.
X - 75 Watt and higher.

With introduction of quad-core CPUs, this numbering scheme was modified by adding new prefixes and re-defining existing ones:

E - desktop dual-core CPU with TDP 55 Watt or higher.
Q - desktop quad-core processor.
X - desktop / mobile dual-core extreme-performance CPU.
QX - desktop / mobile quad-core extreme-performance CPU.

The latest generation of Intel Core ix-branded processors uses yet different processor numbers, that consist of "i3-", "i5-" or "i7-" prefix, and a number.

Along with various prefixes, Intel processor numbers make use of a few suffixes, that indicate specific processor features:

K - Unlocked clock multiplier.
S - Energy efficient version.
X - Extreme version. This suffix is used only on Core ix-branded CPUs.

The first digit, or the prefix letters and the first digit in the processor number, can be used to identify Intel processor family:

The chart above shows the QX6850 as having 4MB L2, shouldn't it be 8MB?

Response: Chart corrected. Thank you!

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.

Hyper threading

Posted by: mec

core i7 s havn 8 processors....s this number 8 indicate that it has 8 processors physical in t...or dat half s duplicated by hyper threading?

Response: Core i7s have 4 or 6 cores, i. e. 8 or 12 logical processors. "8" number in the table for Core i7 CPUs is for the L3 cache size (unfortunately, the table is huge, so it's easy to confuse column titles)

missing E5260 & X5260

2012-02-11 14:55:41

Posted by: stanley_S s.sierpien@gmail.com (Poland)

Xeon X5260 - 2x3,33, 6 MB cache, FSB 1333 :

Xeon X5260 SLANJ (C0) SLBAS (E0)
3.33 GHz 6 MB FSB 1333 10× 0.85–1.35V
TDP 80 W (X) socket LGA 771,
since November 11, 2007

Response: Xeon X5260 is already listed. I can't find any reliable information (part number, S-spec, pictures) on E5260. It seems that many sites list X5260 as E5260. For example, Fujitsu parts shop lists E5260, and has a picture of X5260.
