The Pentium Dual-Core brand was used for mainstream x86-architecture microprocessors from Intel from 2006 to 2009, when it was renamed to Pentium.The processors are based on either the 32-bit Yonah or (with quite different microarchitectures) 64-bit Merom-2M, Allendale, and Wolfdale-3M core, targeted at mobile or desktop computers.
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.
However, due to a demand for mid-range dual-core processors, the Pentium brand was repurposed to be Intel's mid-range processor series, between the Celeron and Core series, continuing with the Pentium Dual-Core line. [11] [12] [13] In 2009, the "Dual-Core" suffix was dropped, and new x86 processors started carrying the plain Pentium name again.
Pentium D [2] is a range of desktop 64-bit x86-64 processors based on the NetBurst microarchitecture, which is the dual-core variant of the Pentium 4 manufactured by Intel.Each CPU comprised two cores.
All models support: MMX L2 cache is off-die and runs at 50% CPU speed; The Pentium II OverDrive is a Deschutes Pentium II core packaged for Socket 8 operation. It comes with 512 KB of off-die full-speed L2 cache, which makes it very similar to the Pentium II Xeon.
The Pentium 4 was a seventh-generation CPU from Intel targeted at the consumer and enterprise markets. It is based on the NetBurst microarchitecture. Desktop processors
