Actually, it tells us that in realistic scenarios there is little or no difference between R7 1700 and 7700k in gaming, once OCed. People don't game at the ridiculously low resolutions needed to stop the GPU being the bottleneck. It also showed us that the 7000k was at almost 100% CPU utilisation on all cores, whereas the R7 1700 was nowhere near being fully utilised.
In that game, at realistic resolutions, on ultra settings, they both do the job.
Let us not forget that no-one at all is recommending that someone with a 7700k trade it for the R7 1700; shoot, they'd have only just have bought it. The big question for gamers, IMO, is whether the 7700k is a viable upgrade to their existing system given that the upgrade path beyond that is non-existent without a new MOBO too. AM4 socket will be around in a few years time, with new and improved CPUs to go with it.
There's no point in comparing something on one metric when that metric doesn't take into account future upgrade paths.
