Comparison of Intel processors

The microprocessor manufacturer Intel refers to its desktop and mobile products since April 2004 after the model name with numbers ( called Model - rating ). According to this rating system the functionality of a processor is better, the higher the number. The first digit indicates in which segment the CPU is arranged. The next two digits are not intended to represent the pure performance within the series, but refer to specific characteristics, such as low power consumption, or features such as EM64T. However, models have especially in the desktop segment with high clock frequency and a higher number. In the mobile sector but also processors with lower power consumption higher numbers, despite much lower clock frequency.

This system has been enhanced with the introduction of the Xeon and Pentium M dual-core processors in late 2005. So a four-digit number rating was introduced, called together with a suffix (for Pentium M) the facilities of the processor.

Desktop processors

NetBurst microarchitecture

All processors have MMX, SSE, SSE2, SSE3 and.

Celeron

Pentium 4

Note: The first Pentium 4 models with model numbers and a 133 MHz FSB (quad pumped FSB533 ) differ from those of the general nomenclature and are treated in a separate section.

Pentium D

Pentium Extreme Edition

Exceptions to the nomenclature

The following Pentium 4 with a FSB of 133 MHz is extremely different from the usual nomenclature from:

Notes:

  • Processors with precursors of Intel Core microarchitecture, the processor cores Banias and Dothan (and their derivatives ) do not have SSE3 and SSSE3!
  • Processors with precursors of Intel Core microarchitecture processor core Yonah ( and its derivatives ) do not have SSSE3!
