Right here we’ll evaluate the 2 CPUs face to face and analyse the paper specs of the 2 CPUs. This could enable you to make an knowledgeable determination as to what CPU may match greatest into your use case. 

5800x vs 5900x

Core depend 

The Ryzen 7 5800x possesses a core depend of eight and the Ryzen 9 5900x options 12 cores. 

Increased core counts imply your CPU might be higher at multitasking natively, nevertheless it all relies on whether or not the sport or app you’re utilizing helps it. Simply because it might doesn’t imply it can. Nonetheless, for many of your everyday actions like internet searching and OS operation, multi-core utilisation is supported, which means the extra cores you may have in your CPU the higher. 

Thread depend 

The Ryzen 7 5800x is available in with a thread depend of 16 and the Ryzen 9 5900x with a thread depend of 24. 

Each of the CPUs on our checklist help SMT or (simultaneous multithreading). This implies one CPU core can course of and execute two directions without delay. This creates a complete thread (logical processor) depend that’s double the core depend. Threads matter once more for multitasking and performance-heavy functions that require lots of muscle to maintain. 

SMT defined

AMD Ryzen 7 5800X vs Ryzen 9 5900X SMT explained

SMT (simultaneous multithreading) is a method to make the most of components of the CPU that might simply be sat round doing nothing in any other case. How SMT works is difficult – put principally, the function permits every core to carry out an extra instruction while ready for an instruction to complete in one other thread. 

The CPU is now capable of make the most of components of itself that might be in any other case doing nothing at that exact second.

The usage of SMT is situational, nonetheless, because the CPU is simply seemingly to make use of one core to run multiple instruction at a time if all cores are already taxed. Bodily cores have precedence over assets and threads endure because of being barely slower than a bodily core.  

The working system sees the processor as having double the cores, however in actuality, all these additional threads solely present a couple of 50%-60% efficiency uplift in a best-case situation, the place an software can divide the load on the system up evenly and that is nearly by no means the case. Some examples of functions that may profit from SMT are functions that deal with video encoding or rendering, the place frames or parts of a picture can all be rendered in their very own thread.

Most older video games aren’t designed with SMT in thoughts as this requires them to be coded explicitly to make the most of SMT and add help to separate duties amongst cores and threads. 

Nonetheless, lots of video games are transferring in direction of SMT help as greater core and thread depend processors develop into extra commonplace. 

A sport developer may break up up numerous parts of a sport to be dealt with by numerous threads, comparable to sound processing, AI and background loading, with the FPS being restricted to no matter course of takes the longest to finish. Graphics drivers and different software program might be working within the background too, and the next core and thread depend can make sure the software program and sport you’re taking part in received’t should combat for CPU cycles. 

The quick reply to that is, CPUs with extra cores and threads are higher for multitasking and CPUs with greater single-core efficiency are favoured for issues like video games for now, however that’s at the moment altering. 

Enhance clock 

The Ryzen 7 5800x has a lift velocity of 4.5GHz and the Ryzen 9 5900x has a lift velocity of 4.8GHz 

On AMD Ryzen CPUs, the CPU enhance clock is outlined because the velocity the processing cores can run with PBO enabled. This stands for precision enhance overdrive,s a expertise that was launched with the 3000 sequence processors. That is AMD’s automated overclocking software program and is designed to be each environment friendly and simple to make use of. 

As recommended, the next clock velocity is best for each single and multicore efficiency because the processing core could make extra cycles per second permitting it to carry out extra calculations per second. PBO works off effectivity and might generally not meet the said enhance velocity, if the temperature is simply too excessive, for instance. PBO, not like handbook overclocks, is wise and adaptive. 

Base clock

The Ryzen 7 5800x has a base velocity of three.9GHz and the Ryzen 9 5900x has a base velocity of three.7GHz 

The bottom clock of a CPU is the core cycles per second the processor can maintain with enough cooling and with none synthetic boosting or overclocking utilized. This successfully offers you a base to match the enhance to and might generally be interpreted as a meaningless statistic.

We expect it’s vital, nonetheless, because it tells us various issues. It tells us the place to base our overclocking potential, the velocity the processor will default to if it’s thermally challenged and offers us efficient enhance efficiencies in comparison with the enhance speeds that may assist us deduce CPU and energy efficiencies. However these issues are all slightly too advanced and pointless if simply deciding what CPU to get subsequent. 


The Ryzen 7 3800x has a a lot decrease L1, L2 and L3 cache in comparison with the Ryzen 9 5900x, which is predicted because of the Ryzen 9’s greater core and thread depend. 

CPU cache is storage {hardware} situated nearer to CPU cores than the principle reminiscence because it’s constructed into the CPU on some ranges, permitting extra environment friendly entry (when it comes to velocity and energy) of knowledge from the principle reminiscence. Cache shops copies of knowledge from most important reminiscence places inside to assist enhance the entry velocity. 

Stage one cache is the cache situated closest to the CPU cores and has the quickest entry speeds but in addition the bottom capability. That is reserved for important information that’s accessed regularly. 

Stage two cache is a center floor, with median capability and the median velocity, reserved for much less important information, however it’s nonetheless integral and perfect that the CPU has snappy entry to it. 

Stage three cache is the place most of your regularly accessed information is saved comparable to applications and file paths. This has a really giant capability compared to the opposite ranges however can be magnitudes slower. 

A better core and thread depend would require extra cache to help these additional cores in case you needed to take care of or enhance the effectivity of CPUs from older generations. 


Each of the CPUs have the identical TDP of 105W 

TDP or thermal design energy is the utmost thermal vitality or warmth a CPU goes to generate. That is the quantity of thermal vitality your cooling resolution might want to dissipate. It’s essential preserve a great temperature to get essentially the most out of our CPU. 

TDP is just not a relentless measure and the TDP doesn’t essentially point out how a lot energy the CPU dissipates at any given time. Moreover, this TDP measurement doesn’t have in mind person overclocks outdoors of the manufacturing unit specs. Making the CPU work more durable by rising its clock velocity and voltage will end in the next TDP.


Each our CPUs match into the identical AM4 socket.

AM4 is the present CPU socket of alternative that includes the PGA (Pin grid array). AMD has managed to maintain this socket in motion for over 5 years however with the up and coming AM5 socket that’s about to vary. 

A socket kind could be regarded as merely a form – solely a CPU matching the socket kind will match that socket motherboard. 
All the components above when Ryzen 7 5800x vs Ryzen 9 5900x are vitally vital.

5800x vs 5900x: Outcomes

The Ryzen 9 5900x takes the win right here and beats the 5800x in each side. With higher specs throughout the board excluding base clock speeds. 

Your greatest wager is the Ryzen 9 5900X. Beating out the 5800x in each clock speeds, core depend and thread depend, the 5900x is your perfect alternative for each gaming and multi-threaded efficiency, however how a lot are you anticipated to shell out for a close to prime canine Ryzen 9 processor? 

5800x vs 5900x: Value

Ryzen 5800x vs 5900x

These processors have aged slightly as they’re greater than a yr previous and offers could be discovered on these CPUs in the correct place, however we’re going to base the worth on launch MSRP. In case you discover a deal, all the higher! 

The Ryzen 7 5800x is available in at a decent value of $449 and the Ryzen 9 at $549, it’s a considerable sum it doesn’t matter what choice you select however is the additional $100 well worth the efficiency and technical advantages the Ryzen 9 brings over the Ryzen 7? 

In brief, we predict so. The Ryzen 9 is a far superior CPU outmoded solely by the 5950X. 

It’s way more environment friendly than the Ryzen 5, packing in an additional 4 cores and eight threads in the identical dimension die with the identical TDP. 

The facility that comes from having an additional 4 cores and eight threads is extremely substantial. You possibly can nonetheless discover processors manufactured right this moment which are much less highly effective than the additional 4 cores and eight threads that the Ryzen 9 has over the Ryzen 7. 

In case you do the maths on these processors, the price per core is as follows: 

Price per core

  • Ryzen 7 5800x – $56.12
  • Ryzen 9 5900x – $45.75

Which means basically, you’re getting extra in your cash in case you go for the pricier 5900x as every core is each quicker and cheaper than these of the 5800x. 


with regards to Ryzen 7 5800x vs Ryzen 9 5900x We favour the extra highly effective, environment friendly and less expensive Ryzen 9 5900x. Its price per core is decrease and it comprises 50% extra cores than that of the 5800X. The upper cache quantity means extra storage for regularly accessed information and a larger core enhance velocity means quicker processing and higher single-core efficiency for the functions that require fewer cores and extra velocity. 

The 5900x is a superb alternative for gaming and multithreaded workloads. The 12 tremendous quick cores all help SMT totalling a formidable 24 logical processors. Though we advocate the 5900x, there’s nothing fallacious with selecting the 5800x both. Additionally the 5800X is a tremendous CPU and among the finest within the business for gaming solely. It simply will fall behind in that regard to the 5900x because it has decrease efficient enhance speeds.  

Each are nice choices however for bang-for-the-buck efficiency, we advocate the Ryzen 9 5900X as your subsequent CPU of alternative.
