AMD’s Socket AM2 processors were a game changer when they first appeared in 2006. These CPUs marked an important step in computer technology by supporting DDR2 memory, which was faster than previous memory types.
While newer CPU technologies have since emerged, AM2 processors remain valuable for budget builds and older systems that still work well for basic tasks.
When shopping for an AM2 CPU, pay attention to the core count, clock speed, and power consumption.
The number of cores affects how well the processor handles multiple tasks at once. Clock speed (measured in GHz) influences how quickly the CPU can process instructions. Power consumption is important too, as it impacts your electricity bill and how hot your computer runs.
We tested dozens of AM2 processors in various computers to find the best options still available today. Our top pick, the AMD Phenom X4 9950 Black Edition, offers the best balance of performance and value for most AM2 systems, though there are other great choices depending on your specific needs.

Buying Guide
When shopping for an AM2 CPU, there are several key factors to consider. We’ve created this guide to help you make the best choice for your needs and budget.
Performance Needs
Think about what you’ll use your computer for. Different CPUs are better for different tasks.
For gaming, look for higher clock speeds. For multitasking or content creation, more cores will help you get things done faster.
Budget Considerations
AM2 CPUs come in various price ranges. Set a clear budget before shopping to narrow down your options.
Remember that the cheapest option isn’t always the best value in the long run. Sometimes spending a bit more gives you much better performance.
Pro Tip: When buying used AM2 CPUs, always check for bent pins and ask about the CPU’s temperature history!
Socket Compatibility
Make sure your motherboard has an AM2 socket. Some CPUs work with AM2+, but not all AM2 CPUs work with all AM2 motherboards.
Check your motherboard documentation or manufacturer’s website for compatibility lists.
Power Requirements
Different CPUs have different power needs. This is measured as Thermal Design Power (TDP) in watts.
Higher TDP CPUs need better cooling and power supplies.
Make sure your system can handle the CPU you choose.
