February 15, 2007 This is a comprehensive chart of all Intel processors
used in the IBM-PC systems. It serves as an introduction to how processor
categorization works, and illustrates the relationship among: product design,
marketing name (series), and technology class (as reflected in codename).
- After 80486, Intel decided to market processors under
consumer-oriented names.
- According to the Pentium I, II, III scheme, we'd be at Pentium XXXII
(32) now.
- Each product code represents a new feature/function/performance design &
architecture.
- Each codename x represent a new technological architecture. The
chips are known as x-class.
- Each marketing name represents a "product line" in a branding sense,
which could include arbitrary number of classes and/or generations of actual
products, in a technical sense.
- Starting at Pentium 4 Xeon, it became simply Xeon.
- The Celeron moniker was used across lines. It could be an edition of
Pentium II/III/4.
- In 2002, Intel started using the Processor Number
nomenclature to identify chips. e.g.:
Celeron D 336 represents Celeron Prescott class
w/ 90nm technology, 256K L2 cache, 2.8GHz clock, 533MHz FSB, Intel-64
standard and NX support.
- Mobile versions often represent completely different architecture, and
even instruction sets.
- The Pentium 4 Era has ended‡. That product line has been succeeded
first by the Core line, and recently, the Core 2 line. Celeron edition of
Pentium 4 generation continues on, only in Prescott class. Currently, there
is no Celeron edition of Core 2.
- Major attributes of a processor include: clock speed, cache
design, levels & size, front-side-bus speed, memory type support, pipeline
stages/depth, multi-core, multi-thread (partial multi-core w/ shared
portion), packaging & socket, fabrication technology generation (expressed
in engineering terms: lambda = x nanometer), operating voltage, power
consumption (wattage), 64-bit instructions set, hardware malware protection
(NX/DEP) and virtualization hypervisor support.

Bold type indicates one-time Bravo standards.
Yellow highlight indicates processors used by current Bravo Sonata and Encore systems.
‡No, it isn't officially EOL yet (but soon will be), but since July 2006, it no
longer has a niche as it's being overlapped by high-end Celeron D in the value
segment, and being replaced by Core 2 in the mainstream/performance segment.
