I spent most of my time testing Windows Server 2008 Enterprise on an eight-core, two-socket AMD Barcelona reference server. When you align the features of the Barcelona architecture with Windows Server 2008's capabilities, you come away with the impression that AMD designed its CPU with Windows Server 2008 in mind. Having talked with Barcelona's architects, I'll bend nondisclosure just enough to say that to call Barcelona a Windows Server 2008 hardware architecture is not far-fetched.
