Wouldn't you compare the i3-8350K with the R5-1500X? Both are 4 cores. The R5 has 8 threads, unlike the 8350's 4 threads. The R5 has 16MB L3 cache, whereas the i3 has 8MB. The advantage for the i3 is absolutely in the base clock being 4Ghz, whereas the XFR for the R5 tops out at 3.9Ghz. The 1500x should manage 4.0Ghz on most chips, but that's not a certainty, and is unlikely to ever get above 4.1Ghz, whereas the i3 should boost well into the 4+Ghz range. So, the true difference will be, where do the prices fall? The R5 is MSRP $189 and I can't imagine that the i3 will be more than $10 away from that either way. And, assuming that I'm wrong there, and Intel places it at $150, the boards are still going to make up the difference in price. So, it then comes down to use case. Do you need more threads? R5. Does what you do like that large L3 cache? R5. Do you need the best possible single thread performance for your buck? i3. There is still the PCI-Express lane advantage of the Ryzen, but if you're in that budget tier, having more than one GPU isn't usually an option, and loosing a bit of NVMe performance isn't going to be a big deal.
