Best AM3+ CPU Review : A Review of the Best AM3+ CPU by AMD

The processor is the brain of your computer. When looking for improved performance or you want to build a solid gaming computer you will want to use a quality CPU.

When AMD released their new set of Bulldozer and Powerdrive chips for use with AM3+ platforms we viewed this as the hope for techies and gaming experts.

With that in mind, it can be challenging to pick the best AM3+ CPU. Some can turn out to be crappy without much help to your performance issue. If you tend to overclock your computer, then you can attest to waiting for your computer to reboot from a crash now and then, especially when using a CPU that is not up to the task.

That’s why you’ll need to look into a better CPU. An AM3+CPU comes with a larger pin socket than its AM3 predecessor. It also has a faster serial link which translates to its improved performance, power regulation, and excellent power quality specifications.

But do they still hold a place against the competition? Let’s find out.

#AM3+ Processor on a Budget

4. AMD FX-6300 Black Edition 6-Core Processor

The AMD FX-6300 made its debut around the same time that the FX-8350 was introduced. Being the upgrade of the FX-6200, this CPU is expected to be a better match for you if you want improved performance without any hitches. It has excellent overclocking capabilities at a very low cost. With this processor, you are guaranteed going beyond the limits of speed with a model that is capable of complex gaming activities, 3D modeling, and HD video editing.

Although this CPU has a base clock speed of 3.5GHz, it can go up to 3.8 GHz. With proper cooling maybe a water cooler, some users have gotten a good 4.82GHz speed. This CPU works with dedicated DDR3-1866 memory with ECC and dual-channel support. It does not, however, have an integrated graphics chip. For a complete package, you’ll still need to have a dedicated card.

When it comes to overclocking, this CPU comes with a completely unlocked clock multiplier which is open for use with the AMD overdrive. It has incredible single performance compared to other CPUs in its class. It also scores high in multi-core performance posting better scores than Intel’s Core i3 6100 which is in the same price range.

If you are a budding PC builder, you may want to save some cash by investing in a CPU that is cheap so you may have extra money to spend on other peripherals. With 95W power consumption, you can choose to use it for regular computer work. But if you are going to use it extensively, then you should expect higher power consumption.

Is this processor ready for gaming needs? Well, if you plan to use this beast for high-demanding games like Battlefield, it will perform as it could be expected with a 6-core processor; efficient with high resolution. It may not be the best for MMO since it can be a drag on its single-threaded performance.

Best AM3+ CPU Buying Guide

When you pull a search for an AM3+ CPU, you are immediately hit with a series of processors, that it makes it hard to distinguish which is better than the rest.

What is AM3+CPU?

The AM3+ socket is an upgrade from the AM3 socket by AMD. It is designed to work with AMD CPUs Vishera (piledriver) and Zambezi (Bulldozer). The AM3+ socket carries 938 pins which are larger than AM3 sockets.

This socket redesigns the serial link for its CPU at 3400KHz to the power controller. It is more power efficient for overclocking purposes since the Bulldozer CPUs can clock at 4.0GHz or higher, while sporting less power consumption at 125W for most AM3+CPUs.

Why should you get an AM3+CPU?

First off, AM3+CPUs are priced much lower than other CPUs with the similar capabilities. With the coming of AMD’s Ryzen family, these CPUs are moving quickly especially if you are looking for USB 3.0 or SATA3 support.

Also, AMD provides the easiest upgrades that we have ever seen. You can install an AM3+ socket on an AM3 motherboard, change the graphics card, add the RAM and you will be dealing with a whole new system that boasts more performance than its predecessors.

Which is the best AM3+ CPU for Gaming?

Apart from the graphics card, the CPU is the second most important component of your gaming PC. From the processors on this list, we have recommended the FX-8350 as the best in its category for gaming. This is because it provides stunning resolutions with up to 24% better frame rates than other AM3+CPUs.

Features to consider when Buying an AM3+ CPU

  • Single Core Performance

With a CPU that has at least six cores and nearly the same number of threads, you may wonder why you even need to consider single core performance. A single core performance is seen in the speeds of a program that cannot efficiently use more cores. In this case, if it is a game that is struggling to use more cores to run faster, then you will need a CPU that is great at single core performance.

Desktop operations are also reliant on single core performance especially if the program is not parallelized, the speeds and all the aspects of that program will rely on the single cell performance of that CPU.

  • Multi-Core Performance

Multi-threaded performance significantly increases the performance of any AM3+CPU. The number of cores means that for programs such as video editing, encoding, decoding, virtualization, 3D designing and many others all depend on the number of cores for them to run faster. For programs that need the help of more threads, choosing an AM3+CPU with up to 8-core is the real deal.

  • Clock Speed

This refers to the number of operations that a processor can handle in a second, measured in Gigahertz (GHz). A high clock speed indicates that the processor can manage more tasks than the one with a low GHz. When a multi-core processor uses multiple threads, it distributes the needs of an operation to the cores thus increasing its speed.

Even with high clock speed, a processor can still be slower than one with a lower clock speed owing to the number of cores. For example, an 8-core 3.5GHz will always beat a 6-core 4.5GHz. But if you are looking for a processor with great single core performance, clock speed is not always that important.

  • Turbo Speed

This is also known as the boost speed. Basically, when your computer senses the need for more clock speed, the CPU will automatically increase this speed for a short period until the performance needs for that particular operation is fulfilled. If you are planning to overclock your PC, you will need to consider how high the CPU can drive the clock speed.

  • Manufacturing Tech

The size of the chip can significantly improve or decrease the performance of the CPU. Modern-day chips can be as small as 14nm. The smaller, the chip the lesser power it requires. Notice that AM3+CPUs use 32nm technology. They are not the smallest chips, and you will notice this with the power requirement. This is something you have to contend with for the multiple-thread performance.

  • TDP-Power Consumption

The amount of power that an AM3+CPU uses will reflect on its performance. Since AM3+CPUs are designed for overclockers and demanding gaming operations, they may require more power which in turn translates to higher temperatures. You will want an AM3+ processor that is efficient on power without increasing its temperature.

Best AM3+ CPU Review- Our Verdict

There you have it; this list provides the best AM3+CPU for various needs. We have found that the FX-8350 is the best performing AM3+ CPU owing to several features. It is a dedicated CPU for overclocking and more so, gaming needs. It can transform your PC into a multipurpose powerhouse since it can handle advanced 3D gaming, complex 3D modeling, and HD video editing.

This CPU can go to 5.0GHz speeds with the help of a proper cooling system. It is compatible with AMD’s cooling solutions, and it comes with a heat sink, fan, and a thermal paste is already applied to the heat sink.

FX-8350 is reasonably priced considering it is an 8-core processor.

But if you are not content with this model, you have four other great choices from the FX-9590 for PC builders to the FX-8370 for consumer desktops.

With an AM3+CPU you are guaranteed excellent performance. We hope you will pick your next processor from the AM3+CPUs on this list.
