The Pentium registered
trademark is included in many
brand names of
Intel's single- and
multi-core x86-compatible
microprocessors. It was first used in
1993 for the
Pentium branded
CPUs with Intel's fifth-generation "P5"
microarchitecture (in
Greek penta means 'five'). Subsequently (and inconsistently), it was used in later generation
CPU's brands (listed below) distinquished by suffixes such as "Pro", "II", "III", "4", "D". In
1998, Intel separated low-priced processors under the
Celeron brand. With the
2006 introduction of the "upper"
Core 2 brand, there was no plan to use the Pentium trademark anymore, but apparently, "Intel developed the
Pentium Dual-Core at the request of laptop manufacturers". So, the brand containing Pentium trademark lost its "upper" position and became "mainstream" between the Core 2 and Celeron - in
2007 and further on as the Pentium brand again.
