The Pentium Dual-Core brand refers to lower-end x86-architecture microprocessors from Intel. They were based on either the 32-bit Yonah or 64-bit Allendale processors.
In 2006, Intel announced a plan to return the Pentium brand from retirement to the market, as a moniker of low-cost Core architecture processors based on single-core Conroe-L, but with 1 MB cache. The numbers for those planned Pentiums were similar to the numbers of the latter Pentium Dual-Core CPUs, but with the first digit "1", instead of "2", suggesting their single-core functionality. Apparently, a single-core Conroe-L with 1 MB cache was not strong enough to distinguish the planned Pentiums from other planned Celerons, so it was substituted by dual-core CPUs, bringing the "Dual-Core" add-on to the "Pentium" moniker. The first processors using the brand appeared in notebook computers in early 2007. Those processors, named Pentium T2060, T2080, and T2130, had the 32-bit Pentium M-derived Yonah core, and closely resembled the Core Duo T2050 processor with the exception of having 1 MB L2 cache instead of 2 MB. All three of them had a 533 MHz FSB connecting CPU with memory. "Intel developed the Pentium Dual-Core at the request of laptop manufacturers". Subsequently, on June 3, 2007, Intel released the desktop Pentium Dual-Core branded processors known as the Pentium E2140 and E2160[6]. A E2180 model was released in 2007. These processors support the Intel64 extensions, being based on the newer, 64-bit Allendale core with Core microarchitecture. These closely resembled the Core 2 Duo E4300 processor with the exception of having 1 MB L2 cache instead of 2 MB. Both of them had an 800 MHz FSB. They targeted the budget market above the Intel Celeron (Conroe-L single-core series) processors featuring only 512 kB of L2 cache.
