The Pentium Dual-Core brand (limited to 2007[1]) refers to lower-end x86-architecture microprocessors from Intel. They were based on either the 32-bit Yonah or 64-bit Allendale processors (with very different microarchitectures) targeted at mobile or desktop computers respectively.
The first processors using the brand appeared in notebook computers in early 2007. Those processors, named Pentium T2060, T2080, and T2130[2], 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[3]. All three of them had a 533 MHz FSB connecting CPU with memory. Apparently, "Intel developed the Pentium Dual-Core at the request of laptop manufacturers"[4].
Subsequently, on June 3, 2007, Intel released the desktop Pentium Dual-Core branded processors[5] known as the Pentium E2140 and E2160[6]. Those 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[7]. 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. Such step marked a change in the Pentium brand, relegating it to the budget segment rather than its former position as the mainstream/premium brand.
In 2006, Intel announced a plan[8] 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 functionallity. 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.
