List of Intel Pentium processors


The Intel Pentium brand was a line of mainstream x86-architecture microprocessors from Intel. Processors branded Pentium Processor with MMX Technology are also listed here. It was replaced by the Intel Processor brand in 2023.

Desktop processors

P5 based Pentiums

"P5" (800 nm)

  • Based on P5
  • Steppings: B1, C1, D1

    "P54C" (600 nm)

  • Based on P5 microarchitecture
  • Steppings: B1, B3, B5, C2, E0

    "P54CQS" (350 nm)

  • Based on P5 microarchitecture

    "P54CS" (350 nm)

  • Based on P5 microarchitecture

    "P55C" (350 nm)

    P6 based Pentiums

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

NetBurst based Pentiums

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

Core based Pentiums

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

"Allendale"">Conroe (microprocessor)#Allendale">"Allendale", "Conroe"">Conroe (microprocessor)#Conroe">"Conroe" (65 nm)

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 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.
  • All models support: MMX, SSE, SSE2, SSE3, SSSE3, Enhanced Intel SpeedStep Technology, Intel 64, XD bit

  • Part of 3MB L2 Cache Disabled
  • E2210 is a Wolfdale-3M with 2MB cache disabled unlike all other E22xx, which are Allendale.
  • E5000-series processors were initially known as Pentium Dual-Core, while all later processors were just Pentium.
