12900k - time spy - cpu test fluctuating

[swrt45]

Hi pc:

12900K with NZXT KRAKEN X73

2x16GB DDR4 KINGSTON DDR4 3600MHZ in GEAR 1

RTX 3090 Ti Gigabyte Gaming

Aorus Z690 Elite DDR4 bios F5

SSD 1 TB NVM PCIE

I have Windows 11 installed the newest version.

I made 5 runs standalone of time spy cpu test. And i have 2000 points differences between run. Why? Temps are ok,other programs closed in background.
Runs:
1 : CPU Score 15 741

2 : CPU Score 15 807

3: CPU Score 17 668

4: CPU Score 15 800

5: CPU Score 17 835

i restarted 3dmark:

run 1 : CPU Score 17 747
run 2 : CPU Score 17 795
run 3 : CPU Score 17 573
run 4 : CPU Score 15 580

any ideas why sometimes its 17k and sometimes 15K?


No gsync during test.Clock 4900mhz in all runs.

can u try cinebench ? maybe the problem is there too.

Maybe you should check the cpu clock graphs and in 3DMark first to see if there is any drop in cpu clockspeed, because this was maybe the case in run4. An almost 2000 points drop in CPU score is of course not normal. Also check the powerplan of windows and if not already done, change to highest performance.

clock is 4900mhz during all tests.
max temp 64c

I tested cpu profile,max threads,16 threadsd,there are no fluctuations.Only in normal timespy.
