The Genesis of GPUs
The tale of GPUs begins with the demand for advanced graphics rendering in the early days of computing. In the 1980s, the world witnessed the birth of the first GPUs as a response to the limitations of CPUs (Central Processing Units) in handling complex graphical tasks. NVIDIA, a name synonymous with GPUs, played a pioneering role by introducing the GeForce 256 in 1999, a GPU that set the stage for a revolution in graphics processing.
What is a GPU?
At its core, a GPU is a specialized electronic circuit designed to accelerate and optimize the rendering of images and videos. While CPUs are versatile and handle a wide array of tasks, GPUs excel in parallel processing, making them the ideal choice for rendering intricate graphics, 3D animations, and complex scientific simulations.
The Anatomy of a GPU
To truly grasp the power of GPUs, one must understand their intricate architecture. A typical GPU comprises thousands of tiny processing cores, each capable of executing multiple tasks simultaneously. This parallelism is what sets GPUs apart from their CPU counterparts, which rely on a smaller number of powerful cores.
