The Intel Pentium 4 HT 631, released in January 2006, is a desktop processor with a single core based on the Cedar Mill architecture, utilizing Socket 775. It features Hyper-Threading, effectively doubling the core count to 2 threads. Operating at 3 GHz with 2 MB of L2 cache, it is built on a 65 nm process with 188 million transistors. The locked multiplier limits overclocking potential. With a TDP of 86 W, it requires adequate cooling. Supporting DDR1, DDR2, and DDR3 memory in dual-channel, it uses PCI-Express Gen 2 for component communication. However, it lacks SSE4 support, which affects compatibility with modern games
