What’s Inside A Graphics Processing Unit?

Synopsis: This week on the podcast, a quick follow-up on the demise of Twitter’s Application Programming Interface (API) and how it’s shut down many useful features, leaving third party Twitter apps with even less parity than before. The main topic of discussion in this episode is that of the Graphics Processing Unit, or GPU for short. They’re inside every computer you own, from your desktop and notebook to your smartphone device. Other than being used to render graphics, do you really know what’s inside a GPU, that is to say, what makes it tick and why it all matters? Nvidia announced its new flagship line of RTX GPUs, which among many things supports ray tracing. What exactly is ray tracing and why does it matter for the future of video games?

GPU (Graphics Processing unit) is an electronic chip which is mounted on a video card (Graphics card). Occasionally called visual processing unit (VPU) is a specialized processor that offloads 3D graphics rendering from the microprocessor. The modern GPU is not only a powerful graphics engine but also a highly parallel programmable processor featuring peak arithmetic and memory bandwidth that substantially outpaces its CPU counterpart.
