46 AMD Athlon™ 64 Processor FAQs Appendix B
plan is for IT managers to seamlessly move to 64-bit applications that benefit their business
while continuing to leverage their investment in 32-bit software and personnel. Additionally,
the HyperTransport™ technology interface addresses the high memory and I/O bandwidth
needs we believe will be required for future personal computers, workstations, and servers.
Q: What specific applications can benefit from the performance of the AMD Athlon 64
processor?
A: Many applications will run faster on the AMD Athlon 64 processor due to its doubled-data
paths. Current 32-bit processors have a 4-GByte memory addressing cap. The 40-bit physical
and 48-bit virtual addressing of the AMD Athlon 64 processor remove that limitation,
permitting up to 1 Terabyte (Tbyte) of physical memory space and 256 Tbytes of virtual
memory addressing space. E-commerce applications, ERP, CRM, and other highly
transactional database applications can benefit from the AMD Athlon 64 processor’s larger
cache, and big workload features that make manipulating larger data sets faster. Other large
data set applications that can benefit from the AMD Athlon 64 processor include CAD and
DCC type applications, as well as financial and scientific modeling applications.
