'Bearlake' chipsets to lack Netburst support?
Recent rumors suggest that Intel will stick with its current LGA775 socket until next year, but the company may not strive to maintain compatibility between current LGA775 chips and future motherboards. According to a purported Intel document seen by HKEPC, future "Bearlake" chipsets will lack support for Netburst-based chips including the Pentium D, Pentium 4, and Celeron D 300 series. The chipsets will only support Core-based Core 2, Pentium E2000, and Celeron 400 processors.
Even among those CPUs, the document suggests compatibility won't be universal. Quad-core Core 2 Extreme and Core 2 Quad processors will supposedly only work with Intel's G35, P35, and X38 chipsets—half of the expected Bearlake lineup. As for Celeron 400-series processors, those won't be supported by the high-end X38 chipset. That said, the move might encourage PC makers and system builders to build low-end systems around Core processors and not their slower and more power-hungry Netburst-based predecessors.
