Intel vs AMD difference?

Here we are again with the same old crapola which is better... If AMD is so bad...why do they exist? If Intel is SOOOOOOOOOOO good then they would be the ONLY CPU maker. even VIA makes some good CPUs just there based on old tech. In the real world (not the nanosecond world) they both can do the same things just the Intel can do it a tad faster...big whoooop...I use AMD a lot cause there cheaper. If a client asks for intel that's what they get. There was a time were AMD had it all over intel and poor intel had to play catch-up now it back to intel on top with speed. here's something to think about...name a program that Intel can run and AMD cant? I didn't say faster I just said a program AMD cant run. ya cant?...mmmm i wonder why? now think..why would I pay $1000 for an intel CPU that will do the same programs that a $300 AMD can do? Oh...and don't forget that AMD based mother boards are generally cheaper than Intel based mother boards!
