Intel to retire 90 nm Pentium 4 600 processors

  • Santa Clara (CA) - Intel informed system builders that it is phasing out its remaining three 90 nm Pentium 4 600-series processors.

     The models 650 (3.4 GHz), 640 (3.2 GHz) and 630 (3.0 GHz) have entered the discontinuance program on January 11; Last orders can be placed May 4 of this year with last shipments of the processors expected to leave Intel's factories on August 3, 2007 (retail processors) and July 4, 2008 (tray processors).

    The announcement leaves Intel with four Pentium 4 processors that have not been placed into discontinuance program. The 631, 641 and 651 carry an identical feature set as the 630, 640 and 650, but are manufactured with the 65 nm Cedar Mill core. The 90 nm 551 model, which integrates only 1 MB of L2 cache (the 600 series has 2 MB) is also still part of Intel's processor roadmap.

    The slow phase out of the old Pentium 4 processors, however, prepares Intel for the introduction of the next-generation single-core processors with Conroe-L core: The E1020 (1.4 GHz), E1040 (1.60 GHz) and E1060 (1.8 GHz) are due within a couple of weeks, according to sources. Dual-core, E2000-series Conroe-L processors are expected for the third quarter of this year.

    The Pentium 4 processor was introduced in November of 2000. It was the firm's first new design since the P6 generation, launched in 1995, and took Intel from the 180 nm "Willamette" chip to the 65 nm Pentium D dual-core CPUs with "Presler" core. Willamette launched with 42 million transistors and 1.4/1.5 GHz clock speeds. The single-core Pentium 600 series topped out at 3.8 GHz.
