5 Best am3+ CPUs that are still Brilliant (in 2021)

Feel like gaming or upgrading your old computer but don’t have enough funds to purchase or build a whole new PC? Do not worry, as I have put together the Best am3+ CPU that are still on the market in 2021. 

Best AM3+ CPUs in 2021

1. AMD FX-8370 Octa-Core Black Edition (Best AM3+ CPU)

2. AMD FX-9590 Black Edition (Runner up)

3. AMD FX-9370 Black Edition (Runner up #2)

4. AMD FX-8350 8 Core Black Edition (Runner #3)

5. AMD FX-6300 Processor Black Edition (Honorable Mention)

1. AMD FX-8370 Octa-Core Black Edition (Best AM3+ CPU)

The AMD FX-8370 Octa-Core Black Edition is an 8 core processor that some users prefer over the FX-9XXX series. It has a lower TDP (Thermal Design Power) of 125W. It is respectively one of the best AM3+ CPUs you can get for your money.

It has 8-cores which produces 4.0GHz base clock speeds and its turbo boost speed can be pushed to 4.3GHz which is not much of a performance bump. Compared to the FX-8350, this CPU doesn’t offer much of a performance increase for the extra dollars. If you aren’t looking to spend too much on a new PSU (Power Supply Unit) and an aftermarket CPU cooler then the added performance may be worth it. It supports DDR3 memory and has up to 1866Mhz System memory specification.

This CPU is unlocked for overclocking and according to users it may be pushed to attain FX-9XXX Speeds. And, that makes this our pick for the best AM3+ CPU you can buy in 2021. It is good for gaming at moderate settings with new titles given that your GPU is up to par and compatible with this CPU.  

PROS

  • Reasonably priced for an eight-core, 4GHz chip
  • Compatible with older AMD AM3+ socket and motherboards
  • Unlocked for overclocking

CONS

  • Only minimally faster than FX-8350, which is cheaper
  • Uses much more power than comparable Intel chips
  • Lacks single-threaded performance compared to Intel competitor chips
  • No integrated GPU

2. AMD FX-9590 Black Edition (Runner up)

AMD’s FX-5950 may be the fastest AM3+ CPU in general. It has 8 cores and a boosted clock speed of 5.0GHz. At its base, it runs at 4.7GHz which for its time was quite powerful. It is still a decent am3+ gaming CPU given that you don’t expect to play new-gen games at their full settings with high refresh rates. If you don’t plan on using this CPU for any GPU related tasks then you are safe. This CPU does not come with integrated graphics. This made intel CPUs a better option at the time as they came with various flavors of integrated Graphics. AMD has great CPU/GPU combinations to alleviate this issue but that comes at an extra cost.

The one thing to take note of before making the buying decision is the amount of heat this CPU generates. This is why most users recommend the FX-8XXX CPUs over FX-9XXX CPUs. You need to buy an aftermarket Liquid CPU Cooler along with the FX-9590 Black Edition. The CPU Cooler that comes with this CPU may lead to a toasted motherboard. 

The AMD FX-9590 comes unlocked which gives you the ability to overclock it. This will help you stay competitive in games. It has a 220W TDP (thermal design power) which demands a dedicated Power Supply of around 750W – 1000W. It is a great am3+ CPU for gaming and features the highest clock speeds seen in any AM3+ CPU out the box.  This is the fastest am3+ CPU in 2021

PROS

  • Ideal for optimized media-crunching tasks
  • Reasonably Priced
  • Can be overclocked

CONS

  • Runs Very Hot
  • Power guzzler
  • No integrated GPU
  • Lacks single-threaded performance compared to Intel competitor chips

3. AMD FX-9370 Black Edition (Runner up #2)

The AMD FX-9370 Black edition is the version below the FX-9590. AMD created the FX-9370 and the FX-9590 as successors of the FX-8350 and the FX-8320. This CPU was created with the Piledriver architecture which succeeded the bulldozer architecture. If you have any of the older CPUs then this would be a great upgrade as it comes with an improved architecture and better performance overall. 

The 8 core design gives you more power to enjoy gaming at higher settings given that you have a compatible GPU with high clock speeds. It pushes 4.7GHz clock speeds when boosted and bangs out 4.4GHz at the base. 

Like the FX-9590, this CPU runs really hot and demands a lot of power compared to its predecessors. With that said, you may need to spare some extra cash for an aftermarket CPU cooler. It has a 220W TDP (thermal design power) which is high compared to FX-8XXX processors so you’ll need to ensure that you have a compatible power supply. More cores and higher clock speeds make the FX-9XXX CPUs a better pick for Power-hungry users. Make sure you feed it the fuel it needs.

PROS

  • Good clock speeds
  • Unlocked for overclocking

CONS

  • Uses much more power than comparable Intel chips
  • No integrated GPU
  • Lacks single-threaded performance compared to Intel competitor chips

4. AMD FX-8350 8 Core Black Edition (Runner #3)

The AMD FX-8350 8-Core Processor is a fan favorite as some people still consider it the best am3 processor. It is the most stable AM3+ CPU meaning it doesn’t tip the scale when it comes to power hunger and performance output. Intel processors give it (And the other processors mentioned) a challenge in single-threaded performance. Although, it does well in multi-threaded tasks.

This CPU pushes 4.0GHz base clock speeds and 4.2GHz when turbo-boosted which is 0.1GHz less than the FX-8370. The black edition is unlocked for overclocking which can give you remarkable performance boosts. It supports DDR3 memory and has up to 1866Mhz System memory specification. 

The TDP (Thermal Design Power) is quite reasonable at 125W compared to FX-9XXX CPUs. Although still uses a lot more power than its Intel competition CPUs. If you seek a reliable AM3+ CPU with a lot of support from the community, this is your best bet.

PROS

  • Reasonably priced for an eight-core, 4GHz chip
  • Compatible with older AMD AM3+ socket and motherboards
  • Unlocked for overclocking
  • Support from the community

CONS

  • Uses much more power than comparable Intel chips
  • Lacks single-threaded performance compared to intel competitor chips
  • No integrated GPU

5. AMD FX-6300 Processor Black Edition (Honorable Mention)

If you are running a budget gaming rig then the AMD FX-6300 Processor might be your best bet. It is the only 6 core (Hexa-Core) processor on this list and it produces a base clock speed of 3.5 GHz and a turbo boost speed of 3.8 GHz. The 8MB cache gives you quick access to data and it is overclock unlocked meaning you can get more clock speeds out of this CPU. 

When it comes to gaming, there is a ceiling with this CPU. You won’t get high frames at full settings as the architecture is outdated in 2021. We recommend this CPU for low budget rigs and encourage you to get a good compatible GPU to run with the FX-6300 CPU. This CPU works better for entertainment and multitasking. If you intend to use this for casual work and browsing then it’s a good fit. 

PROS

  • 6-Core technology is very suitable for multitasking
  • With 8MB of cache, you’ll have faster access to data.
  • Ready to be overclocked

CONS

  • Lacks single-threaded performance compared to Intel competitor chips
  • No integrated graphics

Aftermarket Cooling may be required

Before picking out a specific CPU to go with let me give you a little insight about AMD CPUs. For many years AMD has been known to make Power-hungry CPUs that run hotter than the statistics on product pages. The community has had issues in the past with this. This is one of the reasons Intel has been the better pick for many years. Intel has been consistent at keeping their CPUs at low temperatures and they have done a good job at it. With AMD FX series CPUs, the heat is a significant factor you need to consider. 

AMD bundles its FX Series CPUs with coolers knowing that this is an issue. The truth is that the coolers that come packaged with the CPUs aren’t as good as aftermarket coolers and liquid coolers in general. We recommend putting some money aside to purchase a separate CPU cooler. This will prevent heat issues that come with overclocking your CPU and you may just spare your Motherboard.

Get a good PSU (Power Supply Unit)

Along with the heat issue, AMD FX CPUs have been known to be power guzzlers compared to Intel CPUs that competed with the FX CPUs. In most cases, you may need at least 750W. This will largely depend on your GPUs need for power. You don’t want to have random system shutdowns while you are trying to get some work done. 

Final Words

The AMD FX-8370 Octa-Core Black Edition is our best pick for the best AM3+ CPU. It has a good balance between FX-8XXX CPUs and FX-9XXX CPUs. It comes with the most performance out of all FX-8XXX CPUs while not using up as much energy as the FX-9XXX CPUs. We recommend this as the best AM3+ CPU as it has the potential to reach FX-9XXX performance when overclocked.
