The Intel Pentium 4 HT Extreme Edition 3.40 was a desktop processor with 1 core, launched in June 2004, at an MSRP of $999. It is part of the Pentium 4 HT lineup, using the Gallatin EE architecture with Socket 775. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 2 threads. Pentium 4 HT Extreme Edition 3.40 has 2 MB of L3 cache and operates at 3.4 GHz. Intel is making the Pentium 4 HT Extreme Edition 3.40 on a 130 nm production node using 178 million transistors. The multiplier is locked on Pentium 4 HT Extreme Edition 3.40, which limits its overclocking potential.
With a TDP of 103 W, the Pentium 4 HT Extreme Edition 3.40 consumes a good deal of power, so decent cooling is needed. Intel's processor supports DDR1, DDR2 and DDR3 memory with a dual-channel interface. Actual memory technology support depends on the chosen motherboard, because the memory controller is located on the motherboard (not in the processor). For communication with other components in the machine, Pentium 4 HT Extreme Edition 3.40 uses a PCI-Express N/A connection. Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability.
Neither SSE3 nor SSE4 instruction sets are supported, which will lead to problems with games not starting.
