The Intel Mobile Pentium 4 HT 2.80 was a mobile processor with 1 core, launched in September 2003. It is part of the Mobile Pentium 4 HT lineup, using the Northwood architecture with Socket 478. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 2 threads. Mobile Pentium 4 HT 2.80 has 512 KB of L2 cache and operates at 2.8 GHz. Intel is making the Mobile Pentium 4 HT 2.80 on a 130 nm production node using 55 million transistors. The multiplier is locked on Mobile Pentium 4 HT 2.80, which limits its overclocking potential.
With a TDP of 68 W, the Mobile Pentium 4 HT 2.80 consumes typical power levels for a modern PC. Intel's processor supports DDR1 and DDR2 memory.
Neither SSE3 nor SSE4 instruction sets are supported, which will lead to problems with games not starting.
