CPU’s and GPU’s both make your computer faster, but how do they differ? NVidia, ATI, Intel, and AMD all make chips to do these functions, and you need the right tool for the job, but as computing starts to be more graphics intensive, and graphics cards start to do more than just graphics the line is starting to blur.
CPU’s are the hardware within the computer system that carry out the instructions of a computer program it does this by the basic arithmetical, logical, and input/output operations of the system. The CPU plays a role kind of like the “brain” in the computer. The form, design, and implementation of CPU’s have changed drastically since the earliest examples, but their fundamental operation remains much the same.
GPU or a graphic processing unit is a specialized electronic circuit made to rapidly manipulate and change memory to hasten the building of images in a frame buffer intended for output to a display. GPUs are used in many electronics such as, embedded systems, mobile phones, personal computers, workstations, and game consoles. Modern GPUs are very efficient at manipulating computer graphics, and they have a highly parallel structure which makes them more effective than general-purpose CPU’s for algorithms where processing of large blocks of data is done. In a personal computer, a GPU may be on a video card, or it may be on the motherboard or—in certain CPUs—on the CPU die. Now about 90% of new desktop and notebook computers have integrated GPUs, which are usually less powerful than those on a specific video card.
