    The Pentium 4 Willamette (180 nm) introduced SSE2, while the Prescott (90 nm) introduced SSE3 and later 64-bit technology. Later versions introduced Hyper-Threading Technology (HTT). The first Pentium 4-branded processor to implement 64-bit was the Prescott (90 nm) (February 2004), but this feature was not enabled.

    Please note that some Xeon processors had the same CPUIDs as Pentium 4 Prescott CPUs. Celeron D microprocessors have modified Prescott core that includes 256 KB of level 2 cache memory. To distinguish this core from Pentium 4 Prescott core with 1MB L2 cache the Celeron D core is often called Prescott-256.
    Since Intel definitely won't risk delivery bottlenecks we suppose that the Prescott processor yield is at least 50%. That is backed by the fact that Intel's latest roadmap allows for 4 GHz processors still this year.
    The Mobile Intel Pentium 4 Processor was released to address the problem of putting a full desktop Pentium 4 processor into a laptop, which some manufacturers were doing [citation needed]. The Mobile Pentium 4 used a 533 MT/s FSB, following the desktop Pentium 4's evolution.
