[SOLVED] Insane performance difference on identical computers

[artik3z]

Hello, so the problem I have here is that me and my friend have two very identical computers, and after running two different games, we noticed that the performance is very different, with a considerable 20 to 30 FPS difference staring at the same spots at the same time.

I'll be posting my PC specs below:

MSI X570-A Pro
Ryzen 7 5800X
RTX 3060 TI
DDR 4 G.Skill 3000 MHz 32GB

Now, as for my friend, the only different parts he has are the MB as well as the RAM, which are:

ATX MSI MPGB550 Gaming Edge Wifi
DDR 4 Corsair Vengrance LPX 3200 MHz 32GB

Now, I thought about the difference in the RAM speed being the biggest factor here, but I wouldn't think that it would have such a big impact in all honesty. Can anyone help me out?

1 stick? 2? xmp profile on?

1 stick? 2? xmp profile on?

Both of us have 4 sticks, with XMP profile activated

cpu/gpu temp and usage during the game?
brand and model of psu on each system?

It's not a good thing to get too caught up in the whole "same performance" trap. Every chip, every CPU/GPU, every stick of RAM are subtly different. Motherboards are made and designed with different power parameters between model, much less make. Your house could be a bit warmer. His case might flow a little better. The monitor you are using, the settings, the video cable....it's a rabbit hole. Do you best to optimize your system for smooth playability and enjoyment. Worry less about reported frame rate.

Nice rig, just play,

His temps are definitely lower, mainly on the CPU. Could that be the reason why?

I understand that, it's just that the difference in performance is huge...

Additionally, "identical systems" are alomst certainly not running the exact same software stack at the same time.

"20-30FPS difference"...out of what?

70-100 is possibly noticeable.
170-200 is not.

It was a difference between 70-100 FPS in Borderlands 3 and a difference of 60-80 in New World

RAM timings and latency would matter, anywhere from 5 to 15% (more if he did manual tuning on top of XMP.
also monitor and resolution and GPU settings would matter as well
