1.6 Processor CompatibilityThe 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.
