AMD Radeon RX 6400 Benchmark: FPS and In-Game Performance
Reference CPU: Intel Core i5-13400
The AMD Radeon RX 6400 is the AMD graphics card we cover on this page. Here you'll find its real gaming performance — average FPS (frames per second) across the 20 most popular games at 1080p, 1440p (2K) and 4K (UHD) — its uplift with AI upscaling (DLSS/FSR/XeSS), key specs such as its 4 GB of VRAM, and comparisons with similar GPUs. All figures are estimates from our engine on a reference CPU.

Performance with AI upscaling
Estimated average FPS with FSR enabled, which renders at a lower resolution and reconstructs the image for more frames. Quality and Performance modes trade sharpness for FPS differently.
| Resolution | Native | FSR Quality | FSR Performance |
|---|---|---|---|
| 1080p | 17 | 21 | 25 |
| 1440p | 9 | 12 | 15 |
| 4K | 5 | 7 | 9 |
Estimated values. The real gain varies by game and by how the technology is implemented.
Best CPU for the AMD Radeon RX 6400 & bottleneck
The CPU you pair with the AMD Radeon RX 6400 matters mostly at 1080p; at 1440p and 4K the graphics card itself sets the pace (you are GPU-bound) and the processor is almost irrelevant.
A AMD Ryzen 5 5600 already gets the most out of the AMD Radeon RX 6400 with no bottleneck. Moving to a pricier processor barely adds frames.

Will your CPU bottleneck the AMD Radeon RX 6400?
At 1440p and 4K there is no bottleneck: the AMD Radeon RX 6400 is the limiting component, so any decent modern CPU performs the same. At 1080p a weak processor can hold back a few frames in CPU-heavy games (strategy, simulation or AI-heavy open worlds). As a rule of thumb, a fairly recent 6-core CPU avoids bottlenecking this card.
Frequently asked questions
Is the AMD Radeon RX 6400 good for 1080p, 1440p and 4K?
At 1080p Ultra it averages around 17 FPS; at 1440p (2K) it drops to 9 FPS and at 4K (UHD) to 5 FPS across the most popular games. At higher resolutions, enabling upscaling (DLSS/FSR) helps restore smoothness.
How many FPS (frames per second) are enough?
30 FPS is the playable minimum, 60 FPS the comfortable standard, and 120-144+ FPS ideal for high-refresh monitors or competitive play. In the tables the colour shows the level: green 120+, blue 60+, amber 30+ and red below.
Ultra vs High quality: is it worth it?
Dropping from Ultra to High is barely noticeable yet usually raises FPS by 15-25%. If you want more performance from the AMD Radeon RX 6400, High quality is almost always the best balance of sharpness and smoothness.
Will the CPU bottleneck the AMD Radeon RX 6400?
It depends on the processor and resolution. At 1080p the CPU matters more and an older CPU can bottleneck; at 1440p and 4K the graphics card leads. These figures use a balanced reference CPU.
How much VRAM does the AMD Radeon RX 6400 have, and is it enough?
The AMD Radeon RX 6400 has 4 GB of VRAM (video memory). As a guide, 8 GB is the practical minimum for 1080p, 12 GB is recommended for 1440p, and 16 GB or more for 4K and the games of the coming years.
What does the AMD Radeon RX 6400 score in PassMark, 3DMark, or TFLOPS?
In the spec table above we show its PassMark (G3D Mark) score and TFLOPS as a reference for raw power. But what we really measure at CheckFPS is real in-game FPS across popular titles —what you'll actually notice while playing— not a synthetic score: a high 3DMark number doesn't always mean more frames in your game. That's why the gaming performance you see comes from our own FPS engine.
