| 4. Frequency (MHz) or frequency identifier | |||||||
| Numbers above 200 are processor frequencies in MHz. | |||||||
| Numbers below 200 can be used to identify processor frequency, but there is no easy way to convert them to frequency. For a rough estimate of frequency in GHz use formula "(number + 39) / 40". For instance, for "083" estimated frequency will be (83 + 39) / 40 = 3.05 GHz. | |||||||

| Note to the table above: It is possible to break the item "CPU family and Microprocessor core" into two pieces - 5-digit core technology and one-letter CPU class, but this results in much less accurate identification. 5-digit core technology code can be used to identify base core and manufacturing process. In some cases it's not possible to tell correct CPU core just knowing the 5-digit code. For instance, 80528 Pentium 4s and 80528 Xeons have different core names. CPU class can be used to distinguish between desktop/mobile, and server/workstation/budget processors. Here is how the most common CPU classes can be decoded:
Unfortunately, some Intel processors do not conform to these conventions. For instance, mobile Pentium II processors should have CPU class "G", but they actually have class "K" in their part number. |
