Upgraded cpu = lower fps?

Just replaced my 6800k with a 10900kf (not the plain k version) and done a couple of benchmarks before and after changing cpus.

For 3d mark timespy my cpu score has doubled but ive lost 300 off my gpu score. In assassins creed odyssey benchmark my max fps has dropped by 30fps. I know its not greatly detailed/comprehensive benchmarks tho :) But it has me wondering what it could be.

Overall in games I dont notice any real difference between the two cpus.

Has this kinda thing happened to anyone else? I was a bit worried getting the kf version of the 10900 but went for it anyway as it was oem and much cheaper. Maybe im overthinking this, I dunno.

My specs:
10900kf
gtx 1080ti
Asus strix z490-f
32gb team group vulcan 3200mhz (2x16)
Seasonic 750w psu
 
I could reinstall windows keeping the files etc it's the same thing I think. I wish I done more benchmarks now tbh. You cant run 3dmark in windowed mode as far as I can see. Ive took a pic off the assassins creed one running...

The cores do go to 100% at times but they never hit 5.3ghz during that benchmark or the 7zip one. I asked about this 5.3ghz in another thread but my temps are quite low and I would have thought it should be hitting 5.3 a bit more.

I was watching the core speeds after opening hardware monitor as soon as I could when Windows starts. They do pop up to 5.3ghz for a second now and then.

EDIT: Im not getting any boost at all let alone the 5.3. My cores are all steady on 4.9, I'm not getting 5.1 or 5.2 which are also listed on their website.

Just took a quick min to go on computer and check bios. My ram is set to 2400mhz!! Plus I've got a feature on ai overclock tuner enabled.

I didn't change any bios settings cos I've no time at the min but will take a real good look later. Like my memory def isn't 2400mhz.

Edit: I've not been in the bios really so far, all the settings are at auto. The ram isn't selected at 2400mhz but it's at auto but says 2400mhz as a target.

I done the xmp thing and got the ram to 3200mhz :)

Through this ive began to understand the way it works a bit better. My cpu score now has went up by 1000 in 3dmark. I chnaged the ram settings and got the latest bios as there was 3 newer bios versions out since the one i had.

TBH im gonna give up now and not worry too much more about it. Like youve said on here the benchmarks are a bit funny under different/certain circumstances. Though Radox you are correct and my understanding of the cpu is now much better. Ive spent some time this evening watching hardware monitor and it does go to 5.3ghz, albeit at completely useless times. Also I have found if you take c-states off auto and put it into enabled it (I dunno why) hits 5.3ghz much more often while not under load.

My cpu scores from 6800k to 10900kf..
3dmark timespy 5571 to 13021
Cinebench r23 6823 to 16363
7zip has been almost exactly doubled on both compression and decompression.

Overall very happy with that, it was a good upgrade for me. Intel will bring out new cpus and I imagine its gonna be another waiting around for stock carry on.

Though I will say that cpus and the bios are far too complicated now :D It seems the more you pay the more confused you will be :D

Cheers everyone!

What does the vcore spike to? I must admit though, I love all the endless settings to modern day boards. It makes the older boards BIOS look quite basic.

I will check it later on. The computer couldnt find any bootable hard drive. So it was a case of switching from uefi to legacy I think (I literally can't really remember this and it was only a few days ago lol). I must Google what uefi actually is and what the differences are between it and legacy bios.

I'm thinking about doing a couple of things over the next few days.

1. Reinstalling windows but keeping the files. I have my computer set up the way I like, blocked feature updates, telemetry totally disabled etc and it will be a pain having to do all that as well as going to the latest version of Windows, which I HATE doing.

2. Trying a mild overclock on the cpu, I would be thinking maybe 10% or is that too much. I haven't really looked into it yet though. Looking at the bios settings it seems to be easy enough, maybe even automated for me. The boost clocks are OK and all but largely pointless.
 
My vcore was 1.25-1.35 and went up to 1.45 after the overclock.

The temps went up to 93c and spiked higher. I just done the automated things in the Asus ai software. Might lower it a bit in bios and see if its still worth while. The overclock is def better but is obviously far too hot.

I noticed in the games I'm playing the cpu never hits 100% at all really anyway.
 
Thats a good idea you have of a steady 5Ghz. Did you disbale turboboost in the bios and then set your multiplier to 50 then it stays like that? My full load freq is now 5.1Ghz, it was 49 before I think. My vcore full load is 1.4ish. Im thinking if i do what you did then losing that 100hz might be enough to lower my temps to usable levels. The funny thing is my left leg is cold beside the pc, its a corsair air 540 case sitting flat and the air comes out all around it. Ive just got 3 crappy 120mm fans installed.

Having boost enabled might be better though for things like photoshop, video editing or audio work though.

Was playing apex legends for about an hour, the max cps temp was 83c. The max the cpu goes to now is 5.4ghz, and its doing that a lot just like when i tinkered with c-states in the bios. Also played assassins creed for a short while and the cpu isnt anywhere near maxed and temps were about 60-67. I googled cpu heavy games and that was the only one ive got installed.

So now im wondering when will the cpu, in real world usage, be under a full load .. ermm..

I can put another fan on to the cpu heatsink ive got another bequiet one from my last cooler I can put on.

It's why I don't like Turbo boost. I saw mine hit the 1.4 vcore area once when it hit 5.3. That was when I decided to disable it and keep it at 5Ghz between 1.25 - 1.3. Idle vcore is about 0.68, idles between 25 - 28C and max all cores 72 - 75C. Gaming ranges 45 - 65C.

I've found once above 5GHz requires a lot of voltage for each 100MHz.

After a good tinker ive found the exact same thing as you. At 5ghz theres much nicer vcore at around 3.3, 3.35 max with no spikes. Like you said I tried adding on 100mhz and sure enough the voltage spikes were crazy at even 100mhz more, spiking at 1.447. ALso my temps at 5ghz are the same as yours around 65 under load.
