Intel processor numbers (model numbers) |
|---|
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 have greater performance than processors with smaller numbers. Please note that because different processor families use different ranges of model numbers, the model numbers cannot be used to compare processors from different families. For example, it's not possible to compare this way Celeron and Pentium 4 CPUs. Within the same family 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 processor family:
