In a UMA system, the CPU and GPU share the system’s RAM to handle graphics processing, which can have both positive and negative implications for performance.

How Does UMA Graphics Work?

When a computer boots up, the BIOS (Basic Input/Output System) initializes the hardware components, including the graphics processing unit (GPU). In a UMA system, the GPU is integrated into the CPU or is a separate chip that shares the system’s RAM. The GPU uses a portion of the system’s RAM as video memory to store graphics data, such as textures, buffers, and frame buffers.

The CPU and GPU work together to render images on the screen. The CPU handles the computational tasks, such as processing graphics data, while the GPU handles the graphics rendering tasks, such as drawing pixels on the screen. The shared RAM acts as a buffer between the CPU and GPU, allowing them to communicate efficiently and quickly.

UMA Graphics Modes

There are two main modes of UMA graphics: fixed and dynamic. In fixed mode, the system allocates a fixed amount of RAM for graphics processing, which can be limited and may not be sufficient for demanding graphics applications.
