The Ryzen 7 5800X3D breathed life into the dying AM4 AMD CPUs, but how does it compare to their flagship processor for that generation? In this comparison between Ryzen 7 5800X3D vs Ryzen 9 5900X, we will let you know about their performance difference after testing them across games.

Comparison Table

Architectural Differences

1. Core Count: The Ryzen 9 5900X has 12 cores that total 24 threads, whereas the Ryzen 7 5800X3D has 8 cores and 16 threads, giving the edge to the Ryzen 9 in most multi-threaded workloads.
2. Core Clocks: The clock speeds of the Ryzen 5800X3D are lower than its bigger brother. The processor clocks at 3.4GHz at its base, whereas the Ryzen 9 5900X goes to 3.7GHz. The boosts clocks for Ryzen 7 and Ryzen 9 are 4.5GHz and 4.8GHz, respectively.
3. L3 Cache: The L3 cache on both these processors is pretty plentiful, with the Ryzen 7 having a massive 96MB cache buffer, whereas the Ryzen 9 has a more modest L3 cache of 64MB.
4. TDP: Both the processors have the same rated TDP of 105 watts, though the Ryzen 7 5800X3D chips have a reputation for being highly power efficient. 
5. Processing Nodes: Both these processors are built on the TMSC’s 7nm processing nodes using the Zen 3 architecture. They use the AM4 socket, which has been in use since the first-gen Ryzens.

Gaming Benchmarks At 1080p

To help you better understand the performance differences between these CPUs apart from their specifications, we have put them to the test across 5 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 

• We noticed that the Ryzen 7 5800X3D achieved an average of 123 FPS, slightly ahead of the Ryzen 9 5900X, which reached 122 FPS on average.
• In terms of the 1% low on either processor, the Ryzen 7 5800X3D dropped to 88 FPS, while the Ryzen 9 5900X exhibited a 1% low drop of 93 FPS.

Overall Gaming Performance

We calculated the averages obtained across 5 games, where we saw that the Ryzen 9 5900X obtained an average of 141.3 FPS over the Ryzen 7 5800X3D’s 137.6 FPS – which showcases about 2.87% between the two CPUs. As for the 1% lows, the Ryzen 9 5900X achieved 102.5 FPS over the Ryzen 7 5800X3D’s 97.8 FPS – about a 10% difference.

Pricing And Availability 

As of late mid-January 2024, the Ryzen 7 5800X3D is being sold for around $359, whereas the Ryzen 9 5900X goes for around $346, which isn’t much of a difference. These processors are fairly popular, even with the newer generation out and they are available in most computer parts retailers around the globe.

Ryzen 9 5900X Vs Ryzen 7 5800X3D: Which One Do We Recommend?

At this point, the conclusion seems extremely clear. The Ryzen 9 5900X achieves higher performance when compared to the Ryzen 7 5800X3D all the while costing less. This is why we recommend you blind buy the Ryzen 9 5900X as soon as you can – not only does it perform well in gaming, it’s higher core and threads count allow it to be a perfect productivity task handler as well.
