Intel 17

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 2009) includes 9 desktop and 11 mobile microprocessors. The Pentium Dual-Core CPUs are based on Core microarchitecture, and include many Core micro-architecture features:
  • 32 KB instruction and 32 KB data cache per core;
  • 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.

Pentium Dual-Core processors don't include virtualization technology, and have smaller level 2 cache than Core 2 Duo CPUs.

Mobile Pentium dual-core processors include additional power-saving features, and have lower clock voltage, lower Front-Side Bus frequency and ultimately, much lower power consumption than desktop Pentium Dual-core microprocessors
