For 1080p streaming, a GPU with at least 2 GB of VRAM is recommended, while for 4K streaming, you’ll need a GPU with at least 4 GB of VRAM.
Keep in mind that these are minimum requirements, and you may need more powerful hardware to achieve high-quality streaming with multiple video sources, chroma keying, and other advanced features. It’s always a good idea to check the system requirements for your specific use case and adjust your hardware accordingly.
What is the difference between a graphics card and a GPU?
A graphics card and a GPU are often used interchangeably, but they’re not exactly the same thing. A graphics card is a physical component that you install in your computer, which includes the GPU, memory, and other components. The GPU, or Graphics Processing Unit, is the processor that performs the actual computations for graphics rendering and video encoding.
Think of the GPU as the brain of the graphics card, responsible for handling the complex mathematical calculations required for graphics processing. The graphics card, on the other hand, is the entire package that includes the GPU, memory, and other components. When choosing a graphics card for OBS, you’re essentially choosing a GPU that meets your performance requirements.
