The Intel Pentium Dual-Core brand refers to mainstream x86-architecture microprocessor
Microprocessor
A microprocessor incorporates the functions of a computer's central processing unit on a single integrated circuit, or at most a few integrated circuits. It is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and...

s from Intel. With the exception of a few early Yonah based mobile models, they are now all based on the 64-bit Core microarchitecture. Pentium Dual-Core lacks the SSE4.1 instruction found in the 45 nm Core 2 processors.

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.
