A graphics card or GPU (graphics processing unit) is a key piece of hardware for PC gamers and some professionals – and is responsible for display images on a monitor. If the CPU is the “brains” of a computer, a GPU is the “muscle”.
Whilst some CPUs have integrated graphics, these are general for basic machines using a single monitor, a GPU can support multiple monitors at higher resolutions and refresh rates. Intel’s HD Graphics technology are designed as a means for displaying basic video output, meaning those use their PCs for casual activities are provided with everything they need. AMD’s APU technology – also known as the Advanced Processing Units, functions as bridge between the integrated technology and discrete graphics cards. By implementing the exact same Radeon cores of the discrete GPUs in to the same component as the CPU, the APU allows for a level of quality in gaming that’s extremely close to that of a gaming console.
