OSRS RuneLite usage on a Ryzen 7 5800x

Hi, I would like to ask what is the CPU Usage of an OSRS client logged-in with RuneLite, I have:
Noctua NH-D15 CPU Cooler
16 x 2 GB Ram G Skill TridentZ Neo RGB
SATA SSD
NVidia Geforce GTX 1080
Gigabyte X570 Aorus Ultra Motherboard (planning to buy with Ryzen 7 5800x)
850w Power Supply certified gold.

I would like to also know as a reference to how many accounts I could run with this CPU near 90-100% usage, I am targeting at least 20 OSRS accounts.

Thanks everyone,

 

You could run about 15-25 easily with low detail on

 

I was looking at other performance tests with old Intel CPUs and old Ryzen CPUs, and I found an Intel i7-4930k running 20 OSRS accounts simultaneously at 100% usage with no lagspikes, probably the Ryzen 7 5800x is much better and would run 20 accounts at 40-60% usage and the other half still not used considering Cinebench tests.

I do not have the X570 Gigabyte Aorus Ultra Motherboard and the Ryzen 7 5800X yet but I have everything else, I am using an Intel Core i5 6500 and old motherboard paired with it (low-end for 2015) I can't run more than 5 OSRS accounts with RuneLite or the game gets lagspikes and runs at like 10 FPS with 100% usage.
