This is fantastic news for gamers, as there is now a clear winner in the best CPU for gaming in your next build. The Ryzen 9 5900X is an amazing CPU, and it will only get better with age. The AMD Ryzen 9 5900X is a 12-core, 24-thread monster of a CPU that easily takes the crown as the best gaming CPU on the market.

It offers incredible game performance and will only improve with age as more games are optimized for its Zen 3 architecture. Ryzen 9 is an upgrade of the new architecture from the previous generation; Zen 2 architecture. The direct access to the L3 cache provided by the new Ryzen 5000 is the biggest improvement.

The AMD Ryzen 9 5900X is a true beast of a processor. With the largest gen-on-gen increase in single-core performance in years, it helps in making the chip more powerful. The AMD Ryzen 9 5900X has set the bar high by launching a new gaming processor on the market. It is the quickest mainstream-platform gaming processor we’ve seen so far, apart from 5950X.

The Ryzen 9 5900X is also a great choice for content creators, offering excellent performance in video editing and rendering tasks.

AMD Ryzen 9 5900X Specifications

In terms of specification, the AMD’s Ryzen 9 5900X comes with 12 cores and 24 threads which are powered by AMD’s Zen 3 architecture and TSMC 7nm FinFET process. This powerful AMD chip is unlocked for overclocking and has a base clock of 3.7GHz which can be boosted up to 4.8GHz.

However, another biggest change with the new Zen 3 architecture is the cache. The L1 and L2 caches have increased by 50%, while the all-important L3 cache has more than doubled in size to 64MB in comparison to AMD’s 3000 series (Ryzen 3900X). This will ensure that the new Ryzen 5000 series processors will offer a significant performance improvement over their predecessor.

The more cache memory, the faster its cores communicate. Cache memory also has a quicker communication line to lower memory latency. Overall performance is improved, but better outcomes are obtained, especially in gaming.

The CPU is compatible with DDR4 running at 3200 MHz in a dual-channel mode in terms of RAM specifications along with the support of PCIe 4.0 and has a 105W TDP. Additionally, the problems weren’t found while running it with DDR4-3600. Ryzen 9 can convey the performance of 100-plus FPS in the world’s most popular games. It is not only quick and strong but also easy in the matter of power and cooling systems.

Only motherboards with a 500-series chipset presently support Zen 3 CPUs (such as X570, B550, and A520). And this is workable only if your motherboard builder has released a BIOS update that supports the new CPUs. Some motherboard builders are also adding support for 400 series chipsets such as X470 or B450. For the advanced socket AM4 platform, the CPU works better with PCIe 4.0 on X570 and B550 motherboards.

Pros and Cons of AMD Ryzen 9 5900X

AMD processors have had a very good reputation for years when it comes to powering a personal computing device. Ryzen 9, manufactured by AMD, has been a market leader and has built its reputation through its features.

Thus the processors have many advantages. However, some drawbacks must be considered. Let’s consider some of the Pros and Cons of AMD Ryzen 9 5900X Processors.

Pros of AMD Ryzen 9 5900X

1. Outstanding multithreading performance: Multithreading is very beneficial for large data processing or jobs that rely on external components. Multithreading allows you to run multiple tasks at the same time. As a result, it maximizes CPU utilization through multitasking. Multi-threaded CPU saves a lot of time.

Performance in Different Devices

One of the main aspects of AMD Ryzen 9 5900X is its multi-threaded performance. It comes with 24 threads, which means you can enjoy extraordinary multi-threading performance. With AMD Ryzen 9 5900, there is no need to worry about external factors (slower storage or internet access) while working. It improves the user experience.

When it comes to games, individual frames fasten, so you get more frames per second. You will be able to do more things inside the game without having lags.

2. Unlocked Overclocking: Overclocking, in easy terms, is basically pushing your processor beyond its rated limits. It technically isn’t in the sense that you’re forcing the processor to run at a faster clock speed than usual. This action helps your processor to enhance its performance. AMD allows gamers to overclock their Ryzen CPUs with no restrictions.

Ryzen 9 has a base clock of 3.7GHz and a possible boost clock frequency of 4.8GHz. With an unlocked overclocking speed of 4.8GHz, you can boost performance in high-speed demand applications like gaming and video editing.

3. Excellent gaming performance: The AMD Ryzen 9 5900X is an outstanding gaming processor. Its raw processing performance is outstanding like it’s made to enjoy your game well.

Excellent Gaming Performance

The main reason the AMD Ryzen 9 5900X is fantastic for gaming is that it is really quick. Many computer processors are fast, but the AMD Ryzen 9 5900X is designed to make your games run smoothly. Additionally, you don’t need to upgrade your motherboard. It is backward compatible with many existing Zen 4 motherboards.

4. Supports PCIe 4.0: The higher bandwidth is the main advantage of switching your CPU which supports PCIe 4.0. The CPU, which was designed for PCIe 4.0 (Peripheral Component Interconnect Express) can benefit from the increase in available bandwidth. Devices designed for PCIe 4.0 include faster storage speeds and faster graphics.

AMD Ryzen 9 5900X supports PCIe 4.0. Total PCIe Gen4 lanes on Ryzen 9 CPUs will be 24. Out of twenty-four, four are used for the interconnection to the motherboard chipset, leaving 20 lanes for Gen 4.0 for other uses. They are designed for fast storage.

5. Power Efficiency: AMD Ryzen 9 5900X is delivering a new level of power efficiency. According to AMD, the processor is up to 24 percent more efficient than comparable Zen 2 equivalents. It apparently leads to a 2.4x performance per watt over the first generation of Ryzen chips.

Cons of AMD Ryzen 9 5900X

1. Expensive: The chip has the best performance, but it is a bit expensive. Few other AMD chips which have 8 cores and 16 threads are sufficient for any games or workloads out there. With 12 cores and 24 threads, the 5900x is significantly more costly. No games will be impacted by the additional 4 cores and 8 threads. But, it will have an effect on multicore operations like video editing, file compression, etc.

2. Not included cooler: The chip is already a bit pricey. Additionally, it doesn’t include cooling. You’ll need your cooler for any Ryzen 9 5900X. A CPU cooler works with a lower TDP rating than the TDP of a CPU. Yet, it may not achieve or maintain the greatest boost speeds without adequate cooling.

As previously indicated, most customers looking for high-performance CPUs choose custom cooling rather than the Wraith cooler. The justification is quite decent. However, the CPU is already quite expensive. It costs extra when you get a custom cooler. If you don’t have the money to spend on a third-party CPU cooler, you will have problems with it.

3. No integrated graphics: Most of the AMD Ryzen don’t come with integrated graphics. So, most users use discrete graphics cards instead of integrated graphics cards. AMD Ryzen 9 5900 X comes with no integrated graphics. Integrated graphics generate less heat compared with discrete graphics, and the speed may not reach its true potential. It depends on your use of the CPU.

To increase the speed of these Ryzen CPUs, you may optionally connect a graphics card to them. At the same time, you can also attach separate graphics cards for a better gaming experience.

Price and Availability

There have been numerous conversations on the internet about the AMD Ryzen 9 5900X pricing and how it is expensive. It establishes a new standard of performance in its pricing range. The AMD Ryzen 9 5900X new lowest price is under $400 and is currently available for purchase on the Newegg and Amazon websites. Simply told, the AMD Ryzen 9 5900X is the top consumer-grade processor and is suitable for both gaming and productivity.

View on Amazon

Ryzen 9 is at this point where it is one of the best high-end CPUs. So if you are in the market in search of the best processor, then there is no point ignoring this chip.

The slight hiked price appears to be reasonable. It’s difficult to justify the price increase when the processor is among the greatest ever produced. However, if you’re looking to squeeze every ounce of performance out of the top PC games and multitask, the chip is definitely the best CPU for the task.

Who is it for?

The AMD Ryzen 9 5900X was manufactured to compete with the strongest processors on the planet. Everyone can benefit from it. But, for whom is it designed especially? Let’s have a look into it as well. Below, I have listed a few of them.
