List of Intel Pentium microprocessors

The Intel Pentium brand refers to mainstream x86-architecture microprocessors from Intel. Processors branded Pentium Processor with MMX Technology (and referred to as Pentium MMX for brevity) are also listed here.

Desktop processors based on the P6 microarchitecture were marketed as Pentium Pro, Pentium II and Pentium III, as well as variations of these names.

Desktop processors based on the NetBurst microarchitecture were marketed as Pentium 4 and Pentium D.

Earlier E5xxx desktop processors based on the Core microarchitecture were marketed as Pentium Dual-Core, while later E5xxx and all E6xxx models were called Pentium. Note however, that several resellers will still refer to the newer generation processors as Pentium Dual-Core.

The Intel Pentium Dual-Core processors, E2140, E2160, E2180, E2200, and E2220 use the Allendale core, which includes 2 MB of native L2 cache, with half disabled leaving only 1 MB. This compares to the higher end Conroe core which features 4 MB L2 Cache natively. Intel has shifted its product lines having the Core 2 line as Mainstream/Performance, Pentium Dual-Core as Mainstream, and the new Celeron (based on the Conroe-L core) as Budget/Value.

The E5000 series and E6000 series use the same 45 nm Wolfdale-3M core as the E7000 series Core 2s, which has 3 MB L2 cache natively. 1 MB of L2 cache is disabled, for a total of 2 MB L2 cache, or twice the amount in the original Allendale Pentiums. The Wolfdale core is capable of SSE4, but it is disabled in these Pentiums. Pentium E2210 is an OEM processor based on Wolfdale-3M with only 1 MB L2 cache enabled out of the total 3 MB.
