The only people I REALLY recommend choose Intel over AMD are the competitive, low res, high refresh gamers where Intel's single threaded advantage shows up. That also may be about to change, we will see how Zen 3 plays out, recommendations will adapt as new information emerges. THAT is how it's done.
Thanks, many of these 'bottleneck' benchmarks are at 1080p where the frame rates are well into the 100s of frames per seconds. I have an intel machine and honestly, I wish I would have gone with AMD because about the only thing that Intel is really better at these days is gaming. And with Zen 3, that looks like that won't be the case anymore. When I built my latest PC I didn't do enough research, I just knew that my last AMD machine was not great at gaming compared to the Intel chips that released at the time. I should have done more research into Ryzen, but I didn't and that was my fault. Even the fact that I have to upgrade my motherboard to upgrade to 10th gen is annoying. AMD typically allows more generations to use the same motherboards. I believe the AM4 series motherboards will work with Zen 3, but I'm not 100% sure about that.
But you are correct, the difference between equivalent chips is typically only realize at 1080p, or maybe 1440p, but the framerates are usually over 100 fps already when you see these differences. The more you push your GPU, the less of a problem it usually is. The scary "bottleneck" is really meaningless unless you just have a really old processor or you bought something that doesn't have enough cores for gaming. A 10% bottleneck at 1080p is probably half that at 1440p, maybe even non-existent.
