The top core i9 costs 2k$ on amazon. The top ryzen cost $799. So, they are cheaper than Xeon, but not cheaper than equivalent AMD's processor.
And it is still $960 on Newegg: https://www.newegg.com/Product/Product.aspx?Item=N82E1681911...
The "price-competitive" i9-7900x is 10-cores for $799, and seems to be the best price-competitive comparison. Better single-thread, better at AVX512 tasks, but weaker in general purpose multithreading due to having fewer cores.
As of 2018-06-11 18:27 PDT (when I clicked on that link) the current Newegg price is $799.99.
