AMD Athlon 64 and
XP-M Mobile Processors
AMD Athlon 64.
On January 6, 2004 AMD announced the 3200+, 3000+ and
2800+ mobile Athlon 64 processors. AMD also announced that the 3400+
desktop Athlon 64 would be available for desktop replacement notebooks.
Previously on November 17, 2003, AMD introduced the 3000+ and 3200+
Athlon 64 desktop processors stating that they were for notebook applications.
On that date, Microsoft also announced the release of a beta version
of Windows XP 64-Bit Edition, for AMD 64 bit processors.
About AMD64 Technology
AMD first unleashed AMD64 technology in April 2003 with
the launch of the AMD Opteron™ processor for servers and workstations.
The AMD Athlon 64 processors are the first desktop and notebook processors
based on the AMD64 architecture.
The AMD64 technology follows the evolutionary path of the industry-standard
x86 architecture, allowing development of a unified 64-bit computing
infrastructure designed to be fully compatible with the pervasive x86
architecture. AMD64 technology allows customers to protect their investments
by continuing to use their 32-bit software until they decide to implement
new, 64-bit software.
AMD Athlon XP-M Processors.
On June 17, 2003, AMD announced the Athlon XP-M 2800+
processor, and the Athlon XP-M processors 2000+ and 1900+ low voltage
processors. All three processors have 512KB L2 cache.
AMD announced 12 new mobile Athlon XP-M processors on
March 12- AMD revealed five low-voltage mobile AMD Athlon XP-M
processors at 1800+, 1700+, 1600+, 1500+ and 1400+ with micro PGA packaging,
for the thin-and-light notebook market; five desktop replacement
AMD Athlon XP-M processors at 2600+, 2500+, 2400+, 2200+ and 2000+ speeds;
and two mainstream notebook AMD Athlon XP-M processors at 2400+
and 2200+.
Same Chip, New Name. While AMD should be patted on the back
for finally developing a low voltage mobile Athlon chip, there is nothing
new about the full voltage Athlon XP-M processor except for an increased
L2 cache size (from 256KB to 512KB) in the "desktop replacement"
version..
What AMD is now calling its "mainstream notebook" Athlon
XP-M is the same CPU that used to be called the mobile Athlon XP. This
chip still retains its 128KB L1 cache and 256KB L2 cache.
Performance. AMD claims that overall, the mobile AMD Athlon
XP-M processor 2500+ outperforms the 2.4GHz Pentium 4 Processor-M by
up to 10% on a variety of industry- standard software benchmarks.
Battery life has not been improved except in the low voltage versions
of the processor.
