Even though we owe AMD the credit for creating some of the important architectures that we use, such as amd64, Intel has really ran with these improvements and it comes down to who has the faster processors. Intel chips, while being more expensive, deliver a faster and more stable performance over AMD processors.
This laptop I am typing on id from Intel. Every single laptop my family uses is Intel and Dell together.If you were on your laptop, I bet that it is used Intel. I am not saying the people on iMacs, though. If you have a Dell, know this. Dell uses Intel for every single laptop.
