The eternal debate between NVidia and AMD has been a staple of the tech world for years. With the rise of powerful APUs (Accelerated Processing Units) from AMD, many users are wondering if they can pair their AMD APU with a NVidia graphics card. The short answer is yes, but the long answer is more complicated. In this article, we’ll delve into the world of GPU compatibility, exploring the possibilities and limitations of using an NVidia GPU with an AMD APU.
Understanding APUs and dGPUs
Before we dive into the compatibility question, let’s take a step back and understand the basics of APUs and discrete graphics processing units (dGPUs).
APUs, like those from AMD, combine the central processing unit (CPU) and graphics processing unit (GPU) on a single die. This integration provides improved performance, power efficiency, and cost-effectiveness. APUs are perfect for general computing, web browsing, and casual gaming. However, for more demanding tasks like 3D gaming, video editing, and 3D modeling, a dedicated graphics card is often necessary.
That’s where dGPUs come in. Discrete graphics processing units, like those from NVidia, are standalone graphics cards that can be installed in a computer to boost graphics performance. dGPUs are designed to handle demanding workloads, providing superior performance, higher resolutions, and faster frame rates.
The Compatibility Conundrum
So, can you use an NVidia GPU with an AMD APU? The answer is yes, but there are some caveats.
In theory, any modern PC with an AMD APU can be paired with an NVidia graphics card. The necessary components are:
- An AMD APU (such as the Ryzen 5 or 7 series)
- A motherboard compatible with the APU
- An NVidia graphics card (such as the GeForce GTX 1660 or RTX 3070)
- A power supply unit (PSU) capable of handling the power requirements of both the APU and GPU
However, there are some limitations and considerations to keep in mind:
- Motherboard Compatibility: The motherboard must have a compatible PCIe slot and chipset to support the NVidia graphics card. Not all AMD-compatible motherboards are created equal, so ensure the motherboard can handle the power and bandwidth requirements of the GPU.
- Power Supply Unit (PSU): The PSU must be capable of delivering sufficient power to both the APU and GPU. A minimum of 650W is recommended for most modern setups.

Potential Drawbacks and Limitations
While using an NVidia GPU with an AMD APU can be beneficial, there are some potential drawbacks to consider:
- Increased Power Consumption: Adding a discrete GPU increases the overall power consumption of the system, which can lead to higher electricity bills and heat generation.
- Higher Cost: Buying a separate NVidia GPU can add significant cost to the overall system build.
- Compatibility Issues: As mentioned earlier, compatibility issues can arise due to differences in driver support, motherboard compatibility, and power supply requirements.
Benchmarking and Real-World Performance
To put these benefits and limitations into perspective, let’s look at some benchmarking results.
In a test system with an AMD Ryzen 5 5600X APU and an NVidia GeForce GTX 1660 Super, we saw significant performance improvements in gaming benchmarks:
| Game | AMD APU (iGPU) | AMD APU + NVidia GTX 1660 Super |

What is an APU and how does it differ from a GPU?
An APU, or Accelerated Processing Unit, is a type of microprocessor that combines a central processing unit (CPU) with a graphics processing unit (GPU) on a single chip. This means that an APU can handle both computing and graphics tasks, making it a more efficient and cost-effective solution for certain applications.
However, the integrated GPU on an APU is not as powerful as a dedicated graphics card, and is typically designed for general computing and casual gaming rather than high-performance gaming or graphics-intensive applications. A dedicated GPU, on the other hand, is a separate component that is specifically designed to handle graphics and compute tasks, and offers much higher performance and flexibility.
Can I use an NVIDIA GPU with an AMD APU?
Technically, it is possible to use an NVIDIA GPU with an AMD APU, but there are some limitations and considerations to be aware of. The main issue is that AMD APUs use a proprietary interface to communicate with their integrated GPUs, and this interface is not compatible with NVIDIA GPUs.
As a result, if you want to use an NVIDIA GPU with an AMD APU, you would need to disable the integrated GPU and use the NVIDIA GPU as a discreet graphics card. This may require additional hardware and software configuration, and may not work with all systems or applications. Additionally, you may not be able to take full advantage of the power-saving features of the APU, since the integrated GPU would not be used.
