I've heard that GPU is inside the package of the CPU. That is, CPU has it near itself. Is it true?
If yes, what is the GPU with the graphics video card? Might we have two GPUs one with CPU and the other in the video card?
My next question: It's said the the GPU has much bigger speed in calculating/processing the instructions with less power consuming. Once again, if it's so, why don't manufactures produce only GPUs instead of CPUs?
