ServeTheHome has a review of the 1700X that pits it against various Xeons in server and professional workloads. It does quite well overall here.You should've seen professional forums.
Extasy about the performance, and value.
For people who need a lot of CPU power but don't care that much about AAA gaming, Ryzen will be an excellent value. It's good news for Naples as well - the Zen architecture is strongest in the kind of workloads it is likely to be running.
The truth is that enthusiast sales are likely to be a drop in the bucket compared to upcoming server (Naples) and laptop (Raven Ridge) revenue.
