Im not sure if this is a noob question but i was intrigued about something that i haven't thought about before. When rendering an image, its obvious to see the rendering tiles rendering away the image (the orange squares working on the tiles). But i never thought about this, do they relate to the CPU at all? like to get more rendering tiles, do i need more cores in my processor? The more cores the more orange squares? anyways thanks if anyone would know an answer.
