The Intel Mobile Pentium 4 HT 552 was a mobile processor with 1 core, launched in January 2005. It is part of the Mobile Pentium 4 HT lineup, using the Prescott architecture with Socket 478. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 2 threads. Mobile Pentium 4 HT 552 has 1 MB of L2 cache and operates at 3.467 GHz. Intel is building the Mobile Pentium 4 HT 552 on a 90 nm production process using 125 million transistors. The multiplier is locked on Mobile Pentium 4 HT 552, which limits its overclocking capabilities.
With a TDP of 88 W, the Mobile Pentium 4 HT 552 consumes a good deal of power, so decent cooling is needed. Intel's processor supports DDR1 and DDR2 memory.
The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability.
