There is no substantiated Ryzen 9 5900X3D in the official and independent sources reviewed. The verified 3D V-Cache chip is the Ryzen 7 5800X3D; AMD and Tom’s Hardware compare it with the Ryzen 9 5900X, without “3D” in the model name. In Tom’s Hardware’s 2022 gaming suite, the 5800X3D averaged 21% faster than the 5900X at 1080p. That result does not establish a comparison with a 5900X3D.
Is there a Ryzen 9 5900X3D?
The model name in the question is not supported by the sources available for this comparison. AMD’s official product page lists the Ryzen 7 5800X3D, while AMD’s 2022 launch announcement and Tom’s Hardware’s review identify the Ryzen 9 5900X—not a 5900X3D—as the Ryzen 9 comparison chip. These sources do not establish that AMD released or tested a Ryzen 9 5900X3D.
For a grounded answer to “Which AM4 gaming CPU is faster?”, the relevant comparison is therefore Ryzen 7 5800X3D versus Ryzen 9 5900X.
Which CPU is faster for gaming?
In Tom’s Hardware’s 2022 test suite, the 5800X3D was 21% faster on average than the Ryzen 9 5900X at 1080p. The review’s summary table sets the 5800X3D to 100% and the 5900X to 82.6%. This is one publication’s result for its games, test setup, and settings—not a guaranteed uplift in every game or system.

#1 Best Overall
- The world's fastest gaming desktop processor and first gaming processor with 3D stacking technology
- 8 Cores and 16 processing threads with AMD 3D V-Cache technology
- 4.5 GHz Max Boost, 100 MB cache, DDR4-3200 support
- For the advanced Socket AM4 platform, can support PCIe 4.0 on X570 and B550 motherboards
- Cooler not included, high-performance cooler recommended
AMD published a separate claim in its March 15, 2022 launch announcement: the 5800X3D delivered “up to 15% more gaming performance” compared with processors without stacked cache technology. AMD said this was based on its testing as of December 14, 2021, across six selected games at 1920×1080 High: Watch Dogs Legion, Far Cry 6, Gears 5, Final Fantasy XIV, Shadow of the Tomb Raider, and CS:GO. The Ryzen 9 5900X was one of the comparison systems. AMD’s “up to 15%” figure and Tom’s Hardware’s 21% average are different results from different test methods; they should not be combined into one expected gain.
Why results vary by game and resolution
A suite average describes its particular mix of games; individual titles can produce different rankings and gaps. In five supplementary game results reported by Tom’s Hardware, the 5800X3D led in four and trailed in Grand Theft Auto V. The review also found narrower CPU gaps at 1440p, where the graphics card can become a more important limit on frame rates. A 1080p average is consequently most useful as a comparison under those test conditions, not as a prediction for every resolution, GPU, or game.
Rank #2
- Powerful Gaming Performance
- 8 Cores and 16 processing threads, based on AMD "Zen 3" architecture
- 4.8 GHz Max Boost, unlocked for overclocking, 36 MB cache, DDR4-3200 support
- For the AMD Socket AM4 platform, with PCIe 4.0 support
- AMD Wraith Prism Cooler with RGB LED included
5800X3D specifications and AM4 compatibility
AMD lists the Ryzen 7 5800X3D as an 8-core, 16-thread AM4 processor with a boost clock up to 4.5 GHz, 96 MB of L3 cache, and a default TDP of 105 W. AMD’s product page names X570, X470, B550, B450, and A520 chipsets as supported. Chipset support alone does not guarantee that every motherboard configuration is ready to use the CPU.
Before buying, check the CPU support list and BIOS requirements for your exact motherboard model and revision. Confirm that the board manufacturer lists the 5800X3D as supported and follow its BIOS instructions; do not assume a board will boot with the processor on its existing firmware.

What this comparison means for an AM4 upgrade
If you are choosing between the verified 5800X3D and Ryzen 9 5900X primarily for gaming, the cited benchmark evidence favors the 5800X3D at 1080p. Whether that advantage matters in your setup depends on your games, resolution, graphics card, motherboard support, and the price and availability you can find. The gaming results do not, by themselves, settle which processor is preferable for productivity workloads.
If a listing advertises a “Ryzen 9 5900X3D,” verify the exact processor model before purchase. The evidence-backed comparison here is with the Ryzen 9 5900X, a different model.
