Athlon-64

Athlon-64 is a name for AMD’s main line of 64-bit CPUs.

The Athlon-64 line is designed to complete against the Intel Pentium CPUs.

Athlon-64 processors are designed to execute 32-bit and 64-bit instructions simultaneously. This enables them to directly address more than 4GB of RAM.

Athlon-64 CPUs feature an L1 cache with 64KB of RAM for data and 64KB of RAM for instructions.

The 1024KB L2 cache in an Athlon-64 CPU operates at the full speed of the CPU.

These L1 and L2 cache numbers are per core. In a dual-core Athlon-64 CPU, these numbers would be doubled.

Athlon-64 CPUs include their own built-in memory controller, which reduces latency on memory access.

The HyperTransport bus of the Athlon-64 CPU supports a frequency of 800MHz or 1000Mhz.

Athlon-64 CPUs support MMX, Extended 3DNow!, Cool’n’Quiet,and SSE2. Some models of Athlon-64 CPUs also support SSE3.

Athlon-64 CPUs are designed to fit Socket-754, Socket-939 and Socket-940 CPU sockets.
