The Intel Pentium 4 Extreme Edition 3.40 is a desktop processor with 1 core, released in 2004 at an MSRP of $999. It is part of the Pentium 4 lineup, using the Pentium 4 platform, and fits the 478 socket. Internally, it is built on the "Gallatin" 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 "Gallatin" silicon on a 130nm process node. This processor supports DDR memory. With a TDP of 92W, the Pentium 4 Extreme Edition 3.40 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, 512KB of L2, and 2MB of L3 cache.
Gallatin with 2MB L3. Also released in an LGA775 variant — one of the few CPUs ever offered on two different sockets simultaneously.
