Intel Pentium Dual-Core processor families
Pentium Dual-Core processor family is the latest Pentium-branded
family of budget dual-core desktop and mobile microprocessors. The
family was introduced in the first quarter of 2007 and currently (Feb
2010) includes 15 desktop and 15 mobile microprocessors. With the
exception of one recently released Nehalem Pentium processor, all
Pentium Dual-Cores are based on Core micro-architecture, and include
the following Core features:
- 32 KB instruction and 32 KB data cache per core;
- EM64T technology;
- SSE3 and supplemental SSE3 instructions;
- Wide Dynamic Execution - each core can execute up to 4 instructions per clock;
- Advanced Digital Media Boost - ability to execute one 128-bit SSE instruction each clock cycle.
- Execute disable bit - data memory segments can be marked as non-executable, which prevents external programs to execute malicious program code, that was loaded into system memory as data.
All desktop and mobile Pentiums have smaller size of level 2 cache, and run at lower core and bus frequencies than Core 2 Duo microprocessors released at the same time frame. Earlier desktop CPUs, as well as all mobile Pentium Dual-Core processors don't support Virtualization technology.
"Dual-Core" part was eventually dropped from the family name, and the family is currently branded as "Pentium". Mobile Pentium dual-core processors are currently branded as "Pentium Mobile".

Traditionally, the Pentium brand has always been associated with high-performance desktop processors. Starting from the Pentium Dual-Core family, the brand was "downgraded" to medium-performance and medium-priced processors. During its introduction, in May 2007, the family was positioned between Core 2 Duo family and single-core Celeron 400 series family. First two members of family were E2140 and E2160. Both processors had 1 MB level 2 cache - 2 or 4 times smaller than the level 2 cache on Core 2 Duo processors, but 2 times larger than the L2 cache on Celeron 400 series CPUs. Processor's frequency and Front Side Bus frequency was comparable to those frequencies of Celeron 4xx and the slowest Core 2 Duo processors.
