AMD Ryzen vs FX – Review and Buying Guide

AMD Ryzen vs FX

I think you must have heard about Intel vs AMD, but you might not know about AMD Ryzen vs FX. The purpose of this post is mainly for those who are unfamiliar with AMD‘s newest processors and their names. We will discuss the AMD processor series in this brief post, as well as the benefits of buying one over the other. Our goal with this article is to tell you what processor to buy so that you can make a well-informed and wise decision.

FX Series Processors

Let’s start with AMD FX processors. This generation of AMD processors called “AMD FX” is introduced in 2011. AMD promoted its FX series processors heavily in order to compete with Intel’s Sandy Bridge and Ivy Bridge processors. FX was the first processor series to support true 8-core processors, as opposed to Intel’s dual-core product line which tended to have hyperthreading to 4 logical cores.

Each CPU in this series could be overclocked while still being fairly affordable, making them appealing to PC enthusiasts. Except for the more expensive ones, most processors were locked at their base clock speeds. FX was criticized by reviewers soon after it launched. The Intel FX lineup performed significantly slower than Sandy Bridge due to the common resources between multiple cores. In many single-threaded applications. Phenom II microprocessors were worse than the former generation.

Despite not being as low as the Phenom II generation, this series had a higher power consumption than what Intel was offering at the time. After the piledriver architecture was introduced in 2012, the clock speeds of processors increased across the board with similar power consumption levels.

During that time, the Ivy Bridge architecture was available, delivering greater efficiency in terms of power usage and overall performance compared to the Sandy Bridge architecture. AMD accounted for only 20% of consumer CPU sales in 2016. Over the life of the FX chipset, Intel maintained its lead in the market. There is only the 6-core FX-6300 processor on that list, which is currently available for a very low price. Also, another good choice is an 8-core chip that is popular for its performance and price.

With its affordable price and wide range of features, the FX-8320 is one of the most popular 8-core CPUs currently available. Because of this, it is currently our choice for the best AMD processor available. It offers good performance at a reasonable price. You can also buy good FX processors at a reasonable price from below.

The AMD Ryzen Processors

The AMD Ryzen is a new architecture developed by AMD in February 2017. In the PC world, AMD has introduced a new line of processors specifically designed to battle Intel core i5 and i7 chips. The AMD Ryzen processors are extremely powerful and best suited for gaming PCs.

AMD uses the AM4 socket to house their Ryzen processors, which can also be overclocked by the user. With the release of AMD Ryzen Threadripper series in August 2017, AMD entered the enthusiast workstation market. As well as supporting more memory channels than AMD’s previous Threadripper processor, AMD Ryzen Threadripper also supports additional PCI Express lanes.

Ryzen 7 is a good processor. The number of processor cores plays a role, but the GPU plays a much bigger role in gaming. AMD Ryzen 7 is a great processor choice for rendering and multithreaded applications in general, and it can also be used to play games.

Below are some editors’ pick Ryzen processors that you can purchase.

AMD Ryzen 9 5900X – High Budget Gaming Ryzen Processor

Best Pick

AMD has priced the Ryzen 9 5900X processor at $549, which is about the same price as the current Core i9-10900K street price (it originally launched at around $500). Despite several refinements to the microarchitecture, Ryzen 9 5900X’s CPU cores are built on the same 7 nm silicon fabrication process as the Ryzen 3000 “Zen 2” processor.

One of Zen 3’s biggest changes is that the company has gotten rid of the 4-core CCX and has consolidated all the cores of the CPU chipset into one 8-core CCX. Even within the CPU core, AMD has worked to reduce latencies, improve branch prediction, optimize the execution engine, fatten the front-end and load/store unit, and deploy faster caches, which has a direct effect on IPC.

Gaming performance is largely determined by IPC, and AMD’s 19% claimed IPC gain over “Zen 2” should mean the company has taken the gaming title since “Zen 2” wasn’t too far behind “Comet Lake” anyway.

Are AMD FX processors good? – AMD Ryzen vs FX Battle

Many people want to buy AMD FX processors for gaming purposes, while others want to buy Fx Processors for normal work. AMD FX APUs can give your computer fast speed, smooth performance, and good fps in gaming. The AMD FX processors consist of four modules (not cores) and eight threads, but each thread is weak. Therefore, the FX series did not perform well in running programs and games. That is why AMD FX processors have a bad reputation in the eyes of many users and AMD Ryzen vs FX battle.

Why was AMD FX so bad?

AMD had great expectations for its FX-series processors, but these processors did not meet the user’s requirements. Because of their low reputation, you can find these processors anywhere at a low price. The AMD FX chips cant perform as well as Intel processors, but Intel chips are more expensive and provide good performance. Because of that, Intel processors are usually preferred over AMD FX processors by many users.

Is Ryzen better than FX? – AMD Ryzen vs FX Comparison

In the battle of AMD Ryzen vs FX, a Ryzen processor is completely different from an FX processor series. Word “Different” is more appropriate than “better”. This is not an “update” to the series, it is a completely different processor. Even if you own an FX 8350, it will be useful for a long time. However, unless you can find it super cheap, I wouldn’t recommend grabbing one. If you plan to play any modern game, the FX 8350 can handle it. However, Ryzen is my choice due to its newer technology and better optimization for AAA gaming.

Well if you compare Ryzen 4 core processor to FX 8350. Compared to the FX-8350, Ryzen is not just faster: it is a lot faster, with each core almost two times as fast. I recommend getting the Ryzen.

What is AMD Bulldozer?

AMD Bulldozer is a microprocessor microarchitecture made by AMD for AMD FX and Opteron processors. Bulldozer is the codename of these microarchitectures. It was released in October 2012. Bulldozer’s predecessor is “K10” and its successor is “Piledriver“.

Why was AMD Bulldozer so bad?

The Bulldozer microarchitecture was designed to have a large number of weak cores because AMD anticipated future software being more multithreaded than it is currently. There were also many other problems such as extremely high latency, a slow cache, and high-temperature issues, but it was just a badly designed microarchitecture.

Which is better AMD FX or Ryzen? – AMD Ryzen vs FX

The AMD Ryzen processors are based on fresh and newer “Zen” microarchitecture. The AMD has returned to the high-end CPU market with a product that is challenging to compete with Intel processors. AMD Ryzen has more processing cores. The AMD Ryzen processors provide better multi-threaded performance compared to Intel’s Core chips. The Zen architecture provides 52% faster clock speeds without consuming additional power over the AMD Bulldozer core clock of the previous generation.

The AMD FX series was generally worse performing than its Intel competitors during that time. The FX series’ floating-point performance was relatively poor due to its single shared FPU per module and its high core count. AMD SKUs typically excelled at multithreaded applications. Its power consumption and maximum temperature, however, were often worse than its predecessors.

Now you should know which one is better after reading this. The Ryzen processors are better than FX series processors. Ryzen processors have faster clocks, faster memory, and it has everything a user needs. Ryzen is a much newer generation of processors, whereas FX is much older. That is why I am considering Ryzen over FX processors.

Reasons to Buy AMD FX Processor:

An AMD FX Processor is the best choice if you have a low budget and want your games to run smoothly at normal settings and average frame rates. The processor works well for editing and rendering videos as well. The processor runs at a much higher temperature than the average Intel processor. You are good to go if you want to use this processor for average gaming and video editing tasks. Do not forget to get a good CPU cooler for AMD FX processors!

Reasons to Buy AMD Ryzen Processor:

AMD Ryzen is much better than the FX series. Ryzen is based on AMD’s “Zen” microarchitecture, which is newer and faster. If you’re looking for a CPU with the best performance, features, value, and budget, AMD Ryzen is the best choice. In many ways, Ryzen beats Intel in tests done by many professionals. This processor provides great performance in games, editing, and rendering. Even the lowest tier processor from Ryzen called AMD Ryzen 1400 provides a lot better performance than many Intel processors.

Frequently Asked Questions

Is Ryzen better than FX?

The Ryzen processor isn’t just better than the FX. It’s significantly faster, with each core being almost twice as fast as an FX core.

Is AMD FX bad?

Over its lifespan, the AMD FX line of processors generally performed worse than its Intel rivals. Due to a single shared FPU per module, floating-point performance was relatively poor. AMD SKUs typically excelled in applications that benefited from more threads.  

Why did AMD FX fail?

FX processors were overpriced and overhyped, which meant that they accomplished tasks in the same way Intel processors had been doing for three years or more, but they cost twice as much and used twice as much power.


For me, both processors are good at what they do. AMD FX is best for those who want average gaming performance with moderate settings and for editing, rendering purposes at an affordable price. AMD Ryzen has been designed for those users who have a high budget and who want excellent performance in games at high settings and high FPS. However, if you are looking for more performance, in the battle of AMD Ryzen vs FX I suggest you go with AMD Ryzen series because it is newer and faster than AMD’s previous generations.
