New Pentium 4 core stepping
Although Intel is currently busy converting to the Northwood core, the old Pentium 4 core, the Willamette, which is still manufactured in 0.18µm and has a 256kb L2 cache, is not yet completely extinct. Intel announced a new stepping today.
After the D0 stepping comes this logically the E0 stepping. The processor voltage remains unchanged with the new stepping at 1.75 volts. Except for a few bug fixes, there are no innovations to marvel at. Obviously, Intel is preparing the introduction of the new Celeron , which is based on a stripped down version of the Willamette core, which only comes with a 128kb L2 cache. For the time being, however, the E0 stepping will be used for all Pentium 4 processors manufactured in 0.18 for the 478 socket with a clock rate between 1.6 and 1.9 GHz. However, one should not forget that a Pentium 4 with 1.6 and 1.8 GHz with the new and faster Northwood core is also in circulation.
