The most common key switch for gaming oriented mechanical keyboards is probably the Cherry MX Red. Its actuation point is around 50% of the way through the key travel.
Buckling spring switches, membrane domes, topre (membrane dome + spring), etc. all have actuation points somewhere in the middle of the key travel, not at the start or end.
Is the base clock relevant in any interesting situation? As far as I know it's just telling you what to expect if you disable Turbo Boost in the BIOS.
The frequency at idle should be lower through SpeedStep, and the frequency during load should be higher through Turbo Boost.
If there are thermal limits preventing the maximum turbo frequency from being reached at all times, I still wouldn't expect the average frequency to be related to the base clock. It should be more or less bound by how insufficient the cooling system is. I think even the instantaneous clocks can fall somewhere between the various listed frequencies under throttling conditions.
Also note that the max turbo frequency is different depending on how many cores are loaded.
I think you may have some model numbers and/or benchmark numbers mixed up. I don't see the 6700K or 6700T in the charts in this Ars article.
I see a 7600K with the 637 score, but that lacks hyperthreading and has 25% less L3 cache compared to the 6700T, so it makes sense that the 17% frequency advantage is mostly balanced out (there's little IPC difference between Kaby Lake and Skylake).
Edit: Actually the frequency difference may be a bit off from 17%, that was based off the max single core turbo frequencies. I don't know what the all core turbos are.
I get 220 Mbps downstream through my OpenWRT Archer C7 over ethernet. My service is advertised as 200 Mbps so I don't know how much faster it could go.
I have however read that OpenWRT has significantly worse wireless performance than the stock firmware on this device.
I don't doubt what you're saying other than the number.
