Should run smoothly. So not too many stutters.
A fast processor and a dedicated graphics card. At least 8 GB of RAM would not be bad either.
Processor: i5-H or better, or i7-U. You can forget everything underneath.
May someone add me to AMD. I have no idea.
At least 8GB RAM
Intel Core 6th Gen or better
dedicated graphics card
At least 8 GB of working memory or more would be good.
256 GB storage
Intel core i3, i5
And 2.6ghz
From ryzen 3 2000 onwards, the best 3/4 generation Ryzen 5.
What about you "with mods"? That can be 5, but also several hundred.
Would recommend at least 8GB RAM, but rather 16.
In addition, the processor should be at least an R5 or I5, otherwise it could be scarce.
Minecraft itself doesn't need much. It works perfectly on a laptop with any Ryzen CPU with iGPU.
As far as the mods are concerned, it depends on the mods. The RTX Mod basically requires an RTX 2060 to run stably at 60 fps. There are mods that push good hardware to its limits, especially if you have dozens of mods installed.
But I'm not a Minecraft expert. I only pass on what my son tells me.
With an RTX 2080 and an Intel Core i9-8950HK you are definitely on the safe side. It just costs € 7,000.
