All drivers and firmware are at the latest spec.
Max package power is showing 298.50W (5 minute run) at 60/56/43 XMP Tweaked; let BIOS Optimize; no other changes.
I have 13900ks and using intel enforced limits I am at around 41000 but I do believe that is because the pl1 & pl2 are at 320W as Intel added a new extreme power mode.
Your score looks to me like the CPU prosses is doing other stuff in the background which is messing with your score.
I know there is a bug with Nvidia driver which is causing Higher CPU usage from the NVIDIA Container which is around 10% and then there is Asus lighting service and when you have RGB on that also ads another 5% on the CPU process so having a 15% of the CPU being used at the same time as using R32 will mess with your score.
Maybe do selective start-up making sure no programs are booting with windows etc and if you have Nvidia card get the hot fix driver.
The SP ratings arent comparable from KS to K, nevertheless
To the OP be sure your Windows is configured to see all threads I went from a 12900k to a 13900ks and for some reason windows was only seeign 24 cores.
For some reason Windows had locked 24 cores at boot, to fix write "msconfig" on startup then Boot tab >Advanced Options > Remove the Number of Processors there or set all 32(threads)
