CPU for RX 6900 XT

There is a lot that is going around in the PC market these days. We have three new processors from AMD that were launched earlier this year and later Nvidia released its latest RTX 3000 GPUs followed by AMD who in terms introduced its latest RX 6000 GPUs in the market. With the introduction of the RX 6900 XT, there are many who are thinking which processor is going to be the best companion for the RX 6900 XT so that they are able to get the best out of their setup.

However, before moving directly to our recommendation, let us first get some detailed information about the RX 6900 XT. Currently priced at around $1000, the card is targeted to compete with Nvidia’s RTX 3090 which is priced around $1499 if you are lucky to get it at that price. However, we are yet to find whether the said performance.

The RX 6900 XT is currently the top bidder in the entire 6000 series offering 80 CUs and 5120 shader cores. However, the remaining specs, including memory speed and TDP, are the same as the RX 6800 XT therefore, you can expect more performance from the RX 6900 XT when compared to that of the RX 6800 XT but at significantly double the price. Let us have a look over the detailed specification of the RX 6900 XT.

Advantages of using RX 6900 XT

If you take a close look at the specification, one can come to the conclusion that the RX 6900 XT is a big, bad, and mean one in the entire 6000 series. It has clearly the potential to perform under any circumstances and offer the user the best result. Now apart from the specification, the RX 6900 XT comes with the additional benefits of the RDNA 2 architecture that gives an added advantage to the users who will be using the RX 6900 XT along with the Zen 3 processors from AMD such as Smart Access Memory which helps the processor to utilize all the VRAM present on the graphics card.

Therefore, with all the points to be considered, we will prefer to go with the latest ZEN 3 processors from AMD which will be the best option to consider for this GPU.

AMD Ryzen 9 5900X

Ryzen 9 5900X

12 cores/ 24 threads

Low latency and 19% higher IPC performance than Zen 2 processors

3.7/4.8GHz clock speed

Perfect for gaming at 4K/8K and content creation

AMD announced their latest Zen 3 processor back in the last month and since then there has been quite a hype revolving around those processors. The reason is quite obvious as AMD claims that the Zen 3 series processors are supposed to give you a boost of 19% on IPC gains over the previous Zen series architecture and it definitely is going to give its Intel counterpart a tough fight.

Looking at the specs, it is quite clear that the AMD 5900X offering more cores/threads which have been a trend with AMD. The Ryzen 9 5900X features 12 cores accompanied by 24 threads and offers a base clock frequency of 3.7 GHz and a boost clock of 4.8 GHz. The AMD Zen 3 architecture is more future-proof as it also supports PCIe version 4.0 and the notable thing that I personally felt is an absolute killer feature is a fact that the Ryzen 9 5900X can be used on the same AM4 socket which is more user friendly and easy for the users who are currently using existing AMD Ryzen processor. The increase in the core/thread count results in a massive boost in performance. Also, the Ryzen 5900X is having a lower TPD which makes it more power-efficient.

In terms of gaming, the Ryzen 5900X when combined with the RX 6900 XT will be able to deliver a remarkable performance across all resolutions especially at 3840 x 2160 resolution as it the sweet spot for both the components.

AMD Ryzen 9 5950X

Ryzen 9 5900X

16 cores/ 32 threads

Low latency and 19% higher IPC performance than Zen 2 processors

3.4/4.9GHz clock speed

No compromise performance in any work

The 5950X is the flagship from the AMD Zen3 series and is announced alongside that of the other Zen 3 processors. It is the future-proof replacement of the 3950X and presently it has no competitor out there in the market.

Looking at the specification, it can be said that you can put it inside your PC and you can forget even worrying about the performance. However, the Ryzen 5950X is more of a workstation processor than a gaming one, but if you are even using it in gaming, you won’t be disappointed.

Priced at $800 when announced, the Ryzen 5950X offers 16 cores along with 32 threads and has a TDP of 105W. The Ryzen 5950X offers a base clock frequency of 3.4 GHz and can go all the way up to 4.9 GHz in turbo mode on a single core. However, when all 16 cores are included it can still reach up to 4.5 GHz.

Due to the increase of the IPC, the 5950X can offer an overall increase of 20% in performance when compared with that of the Ryzen 3950X. However, as we mentioned earlier if you are looking for a processor to play games only then this one might not be a perfect choice as to if you are lucky enough, then you might be able to get one at $1500.

In terms of performance, whether it is related to gaming or some multimedia-based works, this processor is capable of handling anything. Thus being said, if you accompany the Ryzen 5950X with that of the RX 6900 XT then, undoubtedly it can handle games with max settings at 4K offering you steady FPS of more than 60.

Intel Core i9 10900K

Core i9 10900K

10 cores/ 20 threads

Fastest Intel processor currently available

3.7/5.3GHz clock speed

Can handle any super high-end GPU like RX 6900 XT easily

From Intel, the Core i9 10900K is the best option that we can think of if you are going to use with the AMD RX 6900 XT and it won’t be letting you down in anyway.

The Intel Core i9 10900K was released back in during the Q2 of 2020 and it comes with a price tag of around $500. Looking at the specs of the Intel Core i9-10900K, it is quite clear that this particular processor is meant to give you satisfactory performance.

Build on the same 14nmm technology, the Core i9- 10900K comes with 10 cores accompanied by 20 threads and offers a base clock frequency of 3.7GHz and a boost clock frequency of 5.3 GHz. It also comes with a higher TDP of 125W and therefore, will require a better cooling solution. This CPU might not be the best fit for 6900 XT but unlike AMD’s 5000 processors, it’s at least available to buy.



Due to the AMD ecosystem, it will be the best option to use the RX 6900 XT with any of the Ryzen 5000 series processors and the best will be the ones listed above as the reason is quite simple. Using the Ryzen 5000 series processor will let you give access to certain features like the Infinity Cache, Smart Access Memory, Direct Storage which will result in a significant performance boost. However, if you are looking to use the AMD RX 6900 XT with that of Intel, then the Core i9 10900K is presently the best you can get for this card.
