Combining Eighth-Generation 32-bit x86 Microarchitectural
Performance with 64-bit x86-64 Architectural Capability
AMD’s eighth-generation processor architecture, code named “Hammer,” ushers
in a complete set of microarchitectural advances while fundamentally altering the nextgeneration
of x86-based system architecture. The result is not only a generational leap in
processor performance, but also a tremendous level of scalability in a system’s delivered
performance. The microarchitecture offers native support for 32-bit x86 software and is
the first to feature support for the 64-bit x86-64 architecture. This combination of
scalable performance for today’s x86 software while enabling the use of the x86-64
architecture will lead to a new level of delivered performance, making the Hammer
architecture a true eighth-generation x86 architecture.
x86-64 Architecture
AMD’s 64-bit strategy allows the latest in processor innovation to be brought to
the existing installed base of 32-bit applications and operating systems, while establishing
an installed base of systems that are 64-bit capable. The Hammer microarchitecture
provides a flexible upgrade path by implementing support for x86-64…
