Have you ever wondered what makes a Gaming PC different than other PC’s? Aside from the light up keyboards and sometimes edgy designs there is one big difference. In short the difference is the GPU. All computers have a GPU (Graphics Processing Unit). The GPU in a gaming computer is a dedicated GPU vs an integrated GPU in a non gaming pc.
What does the GPU do?
The GPU also known as a video card or a graphics card is pretty much a specialized version of a CPU whose purpose is too render video, images and motion graphics.
Most CPU’s have around 2 to 4 cores while GPU’s have thousands or cores. The GPU’s cores are less powerful than the CPU’s but it allows the GPU to perform thousands of small tasks quickly.
Rendering a video game requires millions of small tasks that would simply be too overwhelming for a CPU to handle. However a GPU is able to handle 3D rendering and other tasks games require due to the sheer amount of cores it has.
Dedicated vs Integrated Graphics
Integrated graphics such as Intel HD graphics, are built in to the CPU and share resources with the CPU.
Dedicated graphics like Nvidia graphics cards are installed on the PCI-e slot on the motherboard. Unlike integrated graphics, dedicated graphics cards have their own RAM called VRAM so they don’t have to compete for resources with the CPU.
Because dedicated graphics have to compete with the CPU for RAM this makes them very inefficient for running video games. This is pretty much what differentiates gaming computers from non gaming computers.
