As now we have a basic idea about GPU, let us understand why it is heavily used for deep learning. Moreover GPUs also process complex geometry, vectors, light sources or illuminations, textures, shapes, etc. In short, it is the way in which how an image is formed on a view plane or canvas where the parallel lines converge to a converging point called as ‘center of projection’ also as the object moves away from the viewpoint it appears to be smaller, exactly how our eyes portray in real-world and this helps in understanding depth in an image as well, that is the reason why it produces realistic images. Rasterisation and Ray-tracing are some of the ways of rendering 3d scenes, both of these concepts are based on a type of a projection called as perspective projection. A viewport or viewpoint is a viewer’s perspective of looking to an object depending upon the type of projection used. In the term ‘Graphics Processing Unit’, ‘Graphics’ refers to rendering an image at specified coordinates on a 2d or 3d space. GPU comes with its own processor which is embedded onto its own motherboard coupled with v-ram or video ram, and also a proper thermal design for ventilation and cooling. It is unlike a CPU that carries out multiple tasks at the same time. What is the GPU?Ī GPU or ‘Graphics Processing Unit’ is a mini version of an entire computer but only dedicated to a specific task. But before diving into the depth lets first understand some things about GPU. GPUs have improved year after year and now they are capable of doing some incredibly great stuff, but in the past few years, they are catching even more attention due to deep learning.Īs deep learning models spend a large amount of time in training, even powerful CPUs weren’t efficient enough to handle soo many computations at a given time and this is the area where GPUs simply outperformed CPUs due to its parallelism.
Since the past decade, we have seen GPU coming into the picture more frequently in fields like HPC(High-Performance Computing) and the most popular field i.e gaming.
