Intel Pentium D microprocessor family

Pentium D is a family of Dual-core microprocessors based on Intel NetBurst micro-architecture. The Pentium D CPUs have almost all features of Prescott / Cedar Mill microprocessors - same size of level 1 instruction opcode and data caches, 1 or 2 MB level 2 cache per core, support for SSE3 instructions, Extended Memory 64 Technology and Execute Disable bit capability. The dual-core processors do not include HyperThreading technology. The Pentium D CPUs have higher power consumptions than Pentium 4 processors, but not significantly higher.

For averaged performance of Pentium D processors please see Intel Pentium D multi-threading and single-threading performance pages.

Intel Pentium D 820 - HH80551PG0722MN / BX80551PG2800FN / BX80551PG2800FT

The first generation of Pentium D processors was built on Smithfield core, which was essentially two Prescott Pentium 4 dies in one package. Predictably, many processor features in Pentium D were the same as in the Pentium 4 line of processors. Each core in Pentium D CPU had instruction trace cache with approximately 12K microoperations, 16 KB level 1 data cache and 1 MB level 2 cache. All Smithfield processors included EM64T and execute disable bit features, but none of the processors supported HyperThreading technology. Pentium D CPUs with Smithfield core were offered in frequencies up to 3.2 GHz and had noticeably higher power consumption than Pentium 4 CPUs. The Pentium D microprocessors were manufactured in 775-land LGA package, and they were usually compatible with existing socket 775 motherboards. All Smithfield processors had 8xx processor numbers.

Intel Pentium D 915 - HH80553PG0724MN / BX80553915 / BX80553915R

Next generation of Pentium D microprocessors, based on Presler core, was released less than year after the Smithfield core. Presler Pentium D processors were built on a more modern 0.065 micron technology, which allowed them to reach higher clock frequencies, and double the size of L2 cache. The main advantage of the Presler CPUs, though, was their lower power consumption. Performance-wise Presler CPUs were not much faster than Smithfield processors at the same frequency - Presler's larger L2 cache provided only minor, up to 5%, boost in performance. Some Pentium D processor with Presler core included Virtualization technology. All Presler processors had 9xx processors numbers, and, like the previous generation of Pentium D CPUs, were manufactured in 775-land LGA (socket 775) package.
