As a dual-core integrated-circuit series published in 2005, it delivered multi-core processing within the NetBurst architecture and supported widely used IA-32 and multiple SIMD extension instruction sets (MMX, SSE family). The family occupied a defined period in Intel’s product lifecycle (manufactured 2005–2008) and was succeeded by the Core 2 family, making it a transitional product between single-core NetBurst-era designs and Intel’s later Core microarchitecture lineup. Its LGA 775 socket compatibility and support for common SIMD extensions made it relevant for contemporary desktop platforms and software relying on IA-32 and SSE-class instructions. The Pentium D family is also notable within the broader Pentium brand and as part of Intel’s integrated circuit series catalog. ## Notable For - Dual-core design: Pentium D processors are specified with two processor cores. - NetBurst microarchitecture: The family was built on Intel’s NetBurst architecture. - Instruction set breadth: Officially supports IA-32, MMX, SSE, SSE2, SSE3, plus an additional listed instruction-set entry. - Platform/socket: Uses the LGA 775 socket for desktop platforms. - Defined manufacturing window: Manufactured by Intel with a start_time of 2005 and end_time of 2008;
