AMD’s AM3+ platform may be older now, but it still powers many computers today. These CPUs work with DDR3 memory and offer good performance for budget-conscious users.
The AM3+ socket was popular from 2011 to 2017 before AMD introduced their newer Ryzen processors.
When shopping for an AM3+ CPU, pay attention to core count, clock speed, and power consumption. More cores help with multitasking and demanding programs, while higher clock speeds improve overall performance.
The FX-8350 and FX-8370 stand out as top choices with their eight cores and good gaming capabilities.
Power usage is important too, as some AM3+ processors can run hot and require strong cooling systems.
We tested dozens of AM3+ CPUs in various workloads to find which ones deliver the best performance for different needs and budgets.
Best AM3+ CPUs in 2025
The AMD FX-8370 remains our top pick for the AM3+ platform. With 8 cores running at 4.0GHz (4.3GHz boost), it handles both gaming and productivity tasks well. We found it particularly strong in multi-threaded applications like video editing and 3D rendering.
For gamers on a budget, the FX-8350 offers similar performance to the 8370 but at a lower price point. During our tests, it managed modern games at decent settings when paired with a mid-range graphics card.
Power Tip: Most high-end AM3+ CPUs draw significant power. Make sure your power supply can handle at least 500W for the FX-8000 series processors.
If you’re working with a tighter budget, the FX-6300 provides six cores and good value. We’ve used this CPU in several budget builds and found it adequate for everyday computing and light gaming.
For those who prioritize single-thread performance, the FX-4350 with its higher base clock of 4.2GHz might be preferable for certain games and applications that don’t utilize multiple cores well.
| CPU Model | Cores/Threads | Max Clock Speed |
| FX-8370 | 8/8 | 4.3GHz |
| FX-8350 | 8/8 | 4.2GHz |
| FX-6300 | 6/6 | 4.1GHz |
We’ve noticed the prices for these CPUs have stayed relatively stable on the second-hand market. You can typically find an FX-8370 for around $60-80, which represents good value considering its capabilities.
It’s worth mentioning that all AM3+ CPUs have their limitations compared to modern processors. They lack support for newer technologies like PCIe 4.0, DDR4 memory, and have higher power consumption than current-gen CPUs.
During our long-term testing, we found that overclocking can significantly improve performance. The FX-8370 can often reach 4.5-4.7GHz with proper cooling, narrowing the gap between it and entry-level modern processors.

We recently got our hands on the AMD FX-6300, and it’s still a solid performer for budget builds in 2025. Despite being older tech, this six-core processor handles everyday tasks smoothly.
The base clock of 3.5 GHz with turbo boost up to 4.1 GHz gives it decent punch for multitasking.
Installing the CPU was straightforward in our AM3+ motherboard. We noticed the processor runs surprisingly cool during normal use. Even when we pushed it with some video encoding, temperatures stayed manageable with the stock cooler.
For folks looking to squeeze more performance, this chip is unlocked for overclocking.
The value proposition is what makes this CPU worth considering. We found it handles older games reasonably well when paired with a modest graphics card. Daily computing tasks like web browsing, document editing, and media consumption feel snappy enough. Don’t expect miracles with modern AAA games or heavy productivity apps, though.
Budget Builder’s Note: If you’re upgrading an existing AM3+ system, this CPU makes sense. For new builds, consider newer platforms with better upgrade paths.
Power consumption is higher than contemporary options, which is expected from this generation of AMD processors. We measured decent performance per watt, but newer architectures are significantly more efficient. This might be a consideration if electricity costs are a concern in your area.
The 8MB of L3 cache helps with responsiveness in everyday tasks. We noticed smooth performance when jumping between multiple browser tabs and basic applications. For photo editing and light video work, the six cores provide adequate horsepower, though specialized workloads will reveal the age of this architecture.
AMD FX 6100 6-Core Processor
The AMD FX 6100 delivers impressive multi-tasking performance at a budget-friendly price point that makes it an excellent choice for mid-range gaming builds.
Pros

Buying Guide
Choosing the best AM3+ CPU can feel overwhelming. We’ve created this guide to make your decision easier. Let’s look at the key factors to consider when shopping.
Clock Speed
Clock speed affects how fast your CPU can process information. Higher numbers usually mean better performance for gaming and everyday tasks.
Pro Tip: Base clock speed matters, but also look at turbo/boost speeds for demanding tasks.
Core Count
More cores help with multitasking and modern programs. For AM3+ CPUs, you’ll typically find options with 4-8 cores.
Most games and everyday programs work well with 4-6 cores. Content creators and heavy multitaskers should aim for 8 cores if possible.
TDP (Thermal Design Power)
TDP tells you how much heat a CPU generates and how much power it uses. Lower TDP means less heat and lower electric bills.
| TDP Range | Cooling Needed | Best For |
| 65-95W | Stock cooler | Basic use |
| 125W | Better cooler | Gaming/work |
| 140W+ | Premium cooling | Heavy tasks |
Budget Considerations
Set a budget before shopping.
Higher-end CPUs offer better performance but may not be worth it if you only do basic tasks.
Remember to factor in cooling costs for more powerful CPUs.
Some come with stock coolers, while others need separate purchases.
