Hey there,
I was wondering how much performance difference there is in 2021 between these 2 windows, so in this post i will post some benchmarks that i did on them.
System specs
| CPU | i7-8700k @4.8/5.2Ghz 4.6Ghz IMC |
|---|---|
| GPU | Gigabyte GTX Geforce 1080ti, +20% power, +100Mhz core, +500Mhz Mem Driver version 461.72 for Windows 7, 461.40 for Windows 10 |
| RAM | Gskill 4x8GB 3600Mhz CL16 |
| Motherboard | MSI - Z370 SLI Plus (with A.A0 BIOS) |
| OS Drive | Windows 10 on Intell 660p 1TB m.2 NVME SSD Windows 7 on 240GB LiteOn SATA SSD |
Both Operating system were updated to latest i was allowed ( windows 7 is failing to install some updates ), below are screenshots of winver for both OS.

Benchmarks
Each benchmark specified below were run at same settings in both OS. The best out of 5 runs was selected as the score for that benchmark for that OS.

Overall Windows 10 lost from windows 7 in 13 out of 18 benchmarks benchmarks by overall average of -2.9% which is well above margin of error. So windows 7 still performed better than 10 with both OS updated to max allowed. In PUBG windows 7 won by less than 2 frames margin though as you can see from 1% and 0.1% low figure of both its clear that windows 7’s one was more choppy and it was noticeable, it was happening when gpu usage reached 98%+ then that frame dip then back to smooth while in windows 10 the gpu never went above 96%. Regardless of that, it looks like in avg fps windows 7 was better in gaming than 10. Also, those who do competitive overclocking should take a look at the firestrike scores, the difference between getting more than “High end Gaming PC” was of changing from windows 10 to 7 so this could be the difference between setting world record and being runner up.
. I ran above tests just because Iam using both windows now ( if 1 fails to run some software/hardware or game then i will right away boot to another one ) to get best of both world.
