Intel · Pentium 4 · 2005 · LGA775
The Intel Pentium 4 650 is a desktop processor with 1 core, released in 2005 at an MSRP of $417. It is part of the Pentium 4 lineup, using the Pentium 4 platform, and fits the LGA775 socket. Internally, it is built on the "Prescott" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 2 threads for improved parallelism. It operates at a fixed 3.4 GHz. Intel manufactures the "Prescott" silicon on a 90nm process node. Its multiplier is locked, so any overclocking has to come from raising the base clock rather than the multiplier. This processor supports DDR2 memory. With a TDP of 84W, the Pentium 4 650 sits in a typical power envelope for a modern desktop CPU. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of 16KB of L1 and 2MB of L2 cache. There is no L3 cache on this processor.
6xx series, 2MB L2, EM64T, HT. The 660, 670 and 672 continue the stack at higher clocks — the 670 (3.8 GHz) is already in the database.
