Ryzen 7 5800X3D Vs Ryzen 9 5900X: We Tested Both

Choosing between the Ryzen 7 5800X3D and Ryzen 9 5900X can be tricky because both are strong AM4 processors built on AMD’s Zen 3 architecture. The 5800X3D stands out for gaming thanks to its large 3D V-Cache, while the 5900X offers more cores that benefit creators and multitaskers. I tested both using the same setup, and while their overall performance is close, each chip clearly excels in different areas..

Key Takeaways

We found that the Ryzen 9 5900X held a small lead of about 2.8 percent in average FPS at 1080p, though the difference is minor in real gameplay.
Its higher core and thread count make the Ryzen 9 5900X a stronger choice for users who want extra performance for multitasking and long-term flexibility.
Overall, the Ryzen 9 5900X offers better value for mixed workloads thanks to its strong performance and competitive pricing.

TDP: Both processors share a 105-watt TDP, though the Ryzen 7 5800X3D is known for being a bit more power-efficient under load.
Processing Nodes: Each CPU is built on TSMC’s 7nm process and uses AMD’s Zen 3 architecture with the AM4 socket, ensuring wide motherboard compatibility.

Gaming Benchmarks At 1080p

To get a clearer picture of how these CPUs perform beyond their specifications, we tested both across five popular games at 1080p.

Testing Rig

RAM: Patriot Viper LED DDR4 2×16 GB 3600MHz
GPU: RTX 3090 Ti
SSD: Sabrent Rocket 4 Plus 1TB NVMe SSD
Cooler: Xigmatek Aurora 360mm Cooler

Matrix Awakens Big City Demo

On our first game, the Ryzen 9 5900X showed an average framerate of 112 FPS, whereas the Ryzen 7 5800X3D was ever so slightly behind with 111 FPS.
We observed that the 1% lows in this game hit the same number with both processors reaching 77 FPS.

Elden Ring

Here, the higher cache of the Ryzen 7 5800X3D’s chip makes a difference, as it obtained an average of 130 FPS, over Ryzen 9 5900X’s 126 FPS.
The 1% lows gave the Ryzen 7 5800X3D a win as well, with minimums of 88 FPS, whereas the Ryzen 9 5900X got minimums of around 85 FPS.

God Of War

The performance switched once again on God Of War, where the Ryzen 9 5900X had an average of 140 FPS, whereas the Ryzen 7 had an average of 133 FPS.
The lows had less of a difference, with the Ryzen 7 5800X3D getting around 109 FPS, while the Ryzen 9 5900X got around 111 FPS.

Cyberpunk 2077

Here, we observed the Ryzen 7 5800X3D achieved 125 FPS, while the Ryzen 9 5900X reached 128 FPS, resulting in a difference of only 3 frames.
The 1% lows were relatively smoother on the Ryzen 9 5900X, around 104 FPS, whereas the Ryzen 7 5800X3D was substantially behind with an average of 88 FPS.

Red Dead Redemption 2

Talk about missing the point,how much power do they use while getting almost the same performance!!

Thank you your article ticks all the boxes for my upgrade of just cpu and graphics card from a Rysen 7 5600x and a rx 5800 prier update was 2x16 3200 ram and samsung 2TB 980 ssd m2 maily for gaming I havent desided which graphics card I will wait till next year 🙂

Helped me to choose the 5900x over the 5800x3d for an upgrade.

Good Good Good

Was trying to decide between 5800X3d and 5900X upgrade from 3700X for 1440p gaming, keeping the existing X570 motherboard. Even though very little non-gaming use, that I prefer not to overclock, and pricing is very similar, you have helped me to choose the 5900X. Thanks for unbiased comparison.

Realistik comments for both cpus. Thx...

Very good, found all the information I needed.

👌

Just wonderful

Great detail. Would have been nice to see also 4k results!

Thank you! This article very helpful for me

Great depth of info, thank you

I was thinking about getting one of these 2 CPUs, with this article I can confidently say that 5900x would be my next processor. Thanks!
