Geekbench 6

Hi,
I have two equal laptops, Toshiba Portege Z30-C. They have the same processor, an Intel Core i7-6500U, same amount of RAM memory, same SSD HD size. One of them is running Kubuntu 24.04.4 LTS and the other one is running Windows 11 Pro using a balanced Power Plan.
I have run the Geekbench CPU Benchmark in both of them and the results are much better in the machine running Windows, which was surprising to me. Is there any explanation for that?
For the Windows machine the single core score is 1092 and the multi core score is 2203, while the Linux machine got scores of 849 and 1488.
I checked the Power Management settings of the BIOS and they are the same as well.
Thank you
Albert

It's not the same code on both OS so you really can only compare results in the same OS

Different main boards and firmware, different ssd speeds, different driver code as well.

I understand. Actually, that was the intend, if anything else is the same, the differences in the results of the benchmark should be attributed to the different OS, right?
I've been doing more tests, first I tested the machine that had Windows 11 but now from a live-usb of Kubuntu. Good results. Then i repeated the test several times on the Kubuntu machine. Good results as well this time. I do not know where the bad results on the original test were coming from. Maybe I had other things running on the background.
Anyway, now i can say that, at least at Geekbench 6 results on Windows 11 and Kubuntu 24.04 are almost the same.

Thank you.
