Intel · Pentium 4 · 2004 · LGA775
The Intel Pentium 4 520 is a desktop processor with 1 core, released in 2004 at an MSRP of $163. 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 2.8 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 4 520 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 1MB of L2 cache. There is no L3 cache on this processor.
Prescott on LGA775 — the new socket introduced with Pentium 4 in 2004. 84W TDP (lower than Socket 478 Prescott due to motherboard power delivery improvements). HT enabled.
