All Athlon 64 Models

Athlon II X3 Models

Athlon II X3 is similar to Athlon II X2 and Athlon II X4 CPUs, but with three processing cores instead of two or four. Like other members from Athlon family, this CPU does not have L3 memory cache.

Athlon II X3 uses AM3 socket, but is also backwards compatible with certified AM2+ motherboards. When installed on an AM3 motherboard it supports DDR3 memories, but if you put it on an AM2+ board it will work with DDR2 modules.

Athlon II X3 main features include:

• Three processing cores.
• 64 KB instruction L1 memory cache and 64 KB data L1 memory
  cache for each core /
• 512 KB L2 memory cache for each core.
• HyperTransport (HT) bus running at 2 GHz (8 GB/s). This clock may also be referred as “4,000 MHz.”
• Socket AM3
• Dual channel configuration (you need to install an even number of memory modules to use this feature).
• SSE4a instruction set (which is not the same thing as SSE4 from Intel).

In the table below we list all the Athlon II X3 models released to date. TDP means Thermal Design Power and indicates the thermal dissipation of the CPU, i.e., the CPU cooler must be capable of dissipating at least this amount of heat.
