I think in the coming years the gap will shrink, for amd it already has. My 1920x system is overclocked to 4ghz but that is as far as it will go on air without putting the system outside in the winter. 15% oc is not nothing and I will certainly take it over nothing but my main system running a 2500k at 5ghz is a lot more of an improvement over stock. As long as I can overclock something I will even for just 1% and I think most of the people here are the same way but we are just a small part of the computer market and adaptive tools like Nvidias boost technology allow for the highest number of people to achieve the highest level of performance. The vast majority of people just want to plug in a system and have it run at its fastest potential without any tinkering but it doesn't mean overclocking is dying. Having something pushed close to the limit out of the box just means we have to find a way to raise that limit, for a vega card that could mean power play tables or a shunt mod for Nvidia cards. Lastly even if cpu clock speed is almost at its ambient limit doesn't mean that the system is close to its limit. Tuning ram has a huge impact on lots of applications and workloads especially on ryzen where the clock speeds are almost at the limit of air cooling out of the box. As long as there are settings to change to make a system faster we will change them.
