Not sure that I agree.. if you have truly multithreaded workloads, the R7-2700X is probably a better option... in the end, it depends on your use and how much you want to spend. System cost is also a consideration.
On one hand I agree for "truly multithreaded workloads" - on the other hand having strong single-threaded performance is still a nice feature to have (e.g. when writing prototypes or simply when using simple SW).
I did evaluate about 2 months ago if to go for a 2700X or the usual Intel, and based on the benchmarks I saw, the 2700X is still a bit too weak when running single-threaded SW => I then bought an i7-8700 (no "k") just to be "safe" when running semi-single threaded SW (e.g. my current prototype uses 10 threads but has a single coordination bottleneck).
Let's see what happens in ~January (I think that's when AMD is supposed to present the new CPUs that are supposed to be the "real" next-gen with higher IPC?)
A lot of the time I'm working multi-tier software so will have VM and/or docker containers running in support of what I'm specifically working on. And even then it's mostly node/js based, so the NVME is the single biggest boost to my productivity. In any case, it's often browser + app server + backend services running... so I notice the single-thread performance less. TBH my current CPU (i7-4790k) keeps up reasonably well, though I wouldn't mind more threads and more RAM.
When the GTX 1080 came out, I bumped up to that with a 1TB NVME drive (Samsung) which has been fantastic in limited use. Mostly notice the difference in my npm scripts (ci and build). I'm mostly just itching to upgrade more than feeling pain at this point. I'm pretty sure the Ryzen 2 CPUs (not 2xxx) will be sufficient, as will the mid-upper Intel. However, unless Intel brings their pricing into better competitive range, I may go AMD on my next build.
