Your Intel equivalent is seriously out of date. They’ve since released two new generations. The i5-8600K is a superior option both in performance and price to the i7-6800K. That said for multi-core operations the Ryzen 7 1700 is way better still.
I don’t play much. I’m doing alot of Unity, archviz and VR related stuff. Level design mainly. I saw on some old post some comparison directly in Unity (or unreal, can’t remember now really) - where 1700 had slightly worse than 6800k.
Previous configuration was a Phenom II X4 965 with 16GB DDR3-1333 on an 870 motherboard.
The Phenom II is roughly comparable to a first or second generation Intel Core i7 processor. The Ryzen 5 1600X is thus approximately 50% faster per core and has two more cores than the Phenom II X4 965. Being a programmer I’m greatly affected by compile times and so far I’m seeing a massive improvement. Haven’t timed it but it’s very visible.
