My purpose in writing this article is to give you a review of the AMD RX 6400, the performance you can expect, and the games you can play. My overall review of the AMD RX 6400 is that it is a good budget card that can play modern games but struggles on higher resolutions with higher graphics settings. You would get the AMD RX 6400 if you enjoy playing titles that meet the following criteria:
- You don’t need to play games at higher resolutions like 1440P or 4K
- You don’t expect to play at above 140 FPS
- You are okay with having a graphics card that won’t keep up with new releases in 3-5 years
- You can play games like Red Dead Redemption 2 and Elden Ring, but you will get lower than 60 FPS when using High and Medium graphics settings.
I will provide a list of games you can play along with their ideal resolutions for this card and the graphics quality you can expect.
You can see from the system requirements of Call of Duty: Modern Warfare 2 that the AMD Radeon RX 6400 is not up to 1440P (Competitive Specifications) or Ultra 4K Specifications. It would however exceed its recommended system requirements for 1080P gaming. Use the GPU Engine Specs of the AMD Radeon RX 6400 to compare it below with the system requirements for Modern Warfare 2 / Warzone 2.

What Games Can I Play with the AMD RX 6400?
The processor, RAM, hard drive, and graphics card all play important roles in determining the games you can play. The most important component with this build that we need to focus on will be the graphics card. AMD Radeon RX 6400 is a lower-level graphics card in the 6000 series product line. It was made for entry-level gaming, such as the 1660 SUPER from NVIDIA. It is limited to pretty much 1080P gaming at high graphics quality.
| Game | Ideal Resolutions | Ideal Graphics Settings |
| Elden Ring | 1080P | Medium-High |
| Modern Warfare 2 / Warzone 2.0 | 1080P | High-Ultra |
| Fortnite | 1080P | High-Ultra |
| Halo: Infinite | 1080P | Medium-High |
| CS:GO | 1080P | High-Ultra |
| PUBG | 1080P | High-Ultra |
| Minecraft | 1080P | High-Ultra |
| Red Dead Redemption 2 | 1080P | Medium-High |
| Far Cry 6 | 1080P | Medium-High |
| Dota 2 | 1080P | Ultra |
| Grand Theft Auto V (GTA 5) | 1080P | High-Ultra |
| World of WarCraft | 1080P | High-Ultra |

| Terraria | 1080P | High-Ultra |
| Battlefield 1 | 1080P | High-Ultra |
| Unturned | 1080P | High-Ultra |
Please do note that your results may vary. New patches and changes to the game along with background applications you run will all have an impact on your performance. These are also conservative estimates in most cases so you may be able to get better performance on 1440P resolution than listed here.
What’s a Good Processor to Match the AMD RX 6400?
One of the key elements of building a PC is understanding balance. You will only maximize the potential by so much if you buy an over-powered processor. You could end up wasting money, horsepower, heat, and power if the processor is too powerful. Conversely, you would be wasting the performance of the AMD RX 6400 if you bought an underpowered processor.
Therefore, I would recommend the AMD Ryzen 5600G. The reason for that is that most games do not require more than 6 cores / 12 threads. The 5600G has a base clock of 3.5GHz and a boost clock of 4.4 GHz. You can overclock this processor if you need more than that. The game frequency, or base clock on the AMD Radeon RX 6400 is only ~2GHz and its boost clock is ~2.3GHz. The 5600G should be more than enough for its workload, but not by too much.
Conclusion – The RX 6400 Is an Entry-Level Gamer GPU
The AMD Radeon RX 6400 is an entry-level gamer GPU. You can virtually play any game on 1080P resolution, but you would have to tweak your graphics settings for games like Elden Ring, Far Cry 6, and Red Dead Redemption 2. You should seek balance with a build that uses the AMD RX 6400. I would pair this graphics card with the AMD Ryzen 5 5600G along with 16GB of RAM and an NVME M.2 drive for performance storage.
