Also new to the Athlon XP is the use of a thinner, lighter organic chip packaging compound similar to
that used by Intel Pentium 4 processors.

This packaging allows for a more efficient layout of electrical components. The last versions of the
Athlon XP were made using a 0.13-micron die process that results in a chip with a smaller die that
uses less power, generates less heat, and is capable of running faster than the previous models. The
most recent 0.13-micron versions of the Athlon XP run at actual clock speeds exceeding 2GHz.
The Athlon XP was replaced by Socket A versions of the Sempron.
Athlon MP
The Athlon MP was AMD's first processor designed for multiprocessor support, making it suitable
for server and workstation usage. The Athlon MP was produced in the following four versions, which
are similar to various Athlon and Athlon XP models:
•
Model 6 (1GHz, 1.2GHz)
—This model is similar to the Athlon Model 4.
•
Model 6 OPGA (1500+ through 2100+)
—This model is similar to the Athlon XP Model 6.
•
Model 8 (2000+, 2200+, 2400+, 2600+)
—This model is similar to the Athlon XP Model 8.
•
Model 10 (2500+, 2800+, 3000+)
—This model is similar to the Athlon XP Model 8, but with
512KB of L2 cache.
All Athlon MP processors use the same Socket A interface used by later models of the Athlon and all
Duron and Athlon XP processors.
The Athlon MP was replaced by the AMD Opteron. For more details about the Athlon MP, see the
AMD website.
AMD K8 Processors
AMD's K8 family of processors includes the first 64-bit desktop processors, which set the standard
for 64-bit extensions of the venerable 32-bit x86 architecture. The K8 family is the first x86
