1.6 Processor Compatibility

The Desktop 3rd Generation Intel® Core™ processor family, Desktop Intel® Pentium®

processor family, Desktop Intel® Celeron® processor Family has specific platform

requirements that differentiate it from a 2nd Generation Intel® Core™ processor family

Desktop, Intel® Pentium® processor family Desktop, Intel® Celeron® processor Family

Desktop processor. Platforms intending to support both processor families need to

address the platform compatibility requirements detailed in Figure 1-2.
