That highly depends on what for and what your current hardware consist of, like Motherboard, RAM, GPU, PSU and so on (if you mean an actually CPU, as in the component, and non an entirely new PC as whole).
If you're unsure of what your current hardware is, you can use a tool like Speccy to find out: https://www.piriform.com/speccy

And what country are you buying from, assuming you're not from US/CA, according to the information on your profile. Just for more accurate price estimations.

intel has 1000x more ipc than amd it is the best ty

intel

Intel always places at the top performance wise, however, even I have to say AMD is doing amazing lately, but Intel still has the top.

Depends if it's for gaming, or if it's for content creation.

1600x if content creation/gaming/streaming
7700k if gaming only, or get the 8xxxk for gaming only.

Actually not true it on pair with skylake/kaby lake. It has a 52%+ higher IPC than bulldozer.
But intel has about 20% higher clock speeds which shows in games utilizing low core counts.

both clocked to 4ghz and 4c/8t

max $500 get an intel core i7 8700k, ez as that
