These two chips will be called the Celeron D 352 and 356 and they will be based on the 65nm single-core Cedar Mill. These Celerons will have 512KB L2 cache, double that of the current Celeron D processors, along with a 533MHz FSB and 64-bit support.
The Celerons, revealed in recent internal retail-oriented documentation seen by The Register, will be accompanied by a further 'Cedar Mill'-based P4, the 671, clocked at 3.8GHz like the current Prescott-based 670 and 672. Like the others, the 671 will support HyperThreading, but it lacks the 672's Virtualization Technology support.Soon Intel will also launch the Pentium D 960, which will be a 65nm dual-core chip running at 3.6GHz.
The 671, like the already-launched other members of the 6x1 series, will provide Intel's Extended SpeedStep Technology (EIST), but not until Q2.
