2GHZ - where ny laptop overheats
3GHz- where i cook on my laptop
4GHZ- where i can see real fire on my laptop
5GHz- I die

[Dantido]

2 GHz - no.
3 GHz - Maybe.
4 GHz - Sweet spot.
5 GHz - Maybe a bit overkill.
6 GHz - Arizona summer.

2ghz- for frying eggs
3ghz- for frying bacons
4ghz- for stewing beef
5ghz- for bombing the gates to the underworld

We need 7Ghz cpus, so it finally can run crysis.

Thanks for testing, really interesting to see that different engines scale completely different with those clock speeds. Too bad 6GHz isn't stable under ambient cooling. Would have been interesting to see if the avg fps increased or not. Keep up the good work!

2GHz base and going up:
2GHz -> 3GHz: 50% increase in clk frequency; 38% increase in avg FPS
3GHz -> 4GHz: 33% increase in clk frequency; 16% increase in avg FPS
4GHz -> 5GHz: 25% increase in clk frequency; 13.7% increase in avg FPS
With 2GHz as the base:
2GHz -> 3GHz: 50% increase in clk frequency; 38% increase in avg FPS
2GHz -> 4GHz: 100% increase in clk frequency; 60% increase in avg FPS
2GHz -> 5GHz: 150% increase in clk frequency; 82% increase in avg FPS
*Frame times improve with increasing the frequency*
Only thing missing is power consumption and reliability at given clockspeeds. If performance is desired, 5GHz offers the best performance.

I remember the Pentium 4 2ghz cpu. I had an IBM desktop with that cpu. I was like "Wow", the power of 2ghz! lol!

[TheAbrahamsoto]

3 to 3.5GHZ is the Sweet Spoot before you start to see diminished returns.

[JamesSmith-swnk]

Looks like 4ghz is the golden frequency, most games scale to that point.

[creationstation]

I can't notice any difference. Probably coz I'm watching on a 60hz screen lol.

[gothik]

Going from 2GHz to 3GHz shows quite a fps boost but diminishing returns when you go beyond that, interesting. Did you start getting some form of thermal throttling when you went beyond 3 GHz ? It's a shame we can't see temps here as it would give quite a good estimate of how worth it is to go beyond a certain OC limit or not, temperature wise.

[froznfire]

Keep in mind that this also depends heavily on the GPU, meaning if you have a 150$ GPU, the difference will be way smaller.

[reelauxmedia]

CPU clock does matter.But when it comes to different architecture it becomes complex to answer.

[kuksio]

Its funny to see that the CPU utilization is almost always the same across the board, no matter the GHZ cores are at.
That shows that 8 cores arent fully utilized in most ot these games.

6 cores is the sweet spot right now.

[Zachsnyder]

1:09 the horse colour is getting darker from 2ghz to 5ghz

[jeffm]

The way I see it is all of these frame rates are playable, especially if you don't know any better.

[dy]

it actually also depend on the CPU. One Intel and AMD CPU might perform & behave differently even with the same clocks, cores, and threads.

[yosifvidelov]

Please include wattage used and temperatures and cooler used.

[TheOfficialNukeDem]

For people watching, keep in mind some games will perma crash, bug/glitch out, stutter, have issues loading, or won't even launch among other problems (and sometimes all of them xd) if your frequency is too low, usually it happens if it's below 3ghz but newer games may ask for more.

There's a reason why even a 80€ 9100f can go to 4ghz and higher.

[umnoname]

Thank you for the video, , been looking for something like this for a while. I only wish you did this with games that I play like apex, COD MW, R6S, overwatch
