HyperTransport I/O
Hub
Data Sheet
The
AMD Athlon 64 and AMD Opteron
processors power the next generation in
computing platforms, designed to deliver the
ultimate performance for cutting-edge
applications and an unprecedented computing
experience. The AMD-8000 series of chipset
components is a highly integrated system logic
solution that delivers enhanced performance and
features for the AMD Athlon 64 and
AMD Opteron processors.
