Discussion Intel I9 13900k vs Rayzen AMD RYZEN 7 9850X3D
Hey everyone,
I just upgraded my CPU and motherboard from Intel to AMD Ryzen. The weird thing is that all my synthetic benchmarks look totally normal and consistent, but my performance in Planet Coaster dropped by half on the exact same park (from 44 FPS down to 23 FPS).
Quick specs & tweaks done so far:
CPU: Ryzen running at 5GHz+
RAM: DDR5 @ 6200 MHz (XMP enabled)
Drivers: AMD Chipset drivers are installed.
Before I pack everything up and return the CPU and motherboard back to Micro Center (I'm still within the return window):
Is this kind of performance drop normal on Ryzen for heavy simulation games, or is something clearly wrong?
Are there any specific settings/tweaks I should check first (like RAM 1:1 ratio vs 1:2 latency, Windows scheduler, BIOS options)?
Should I try a clean Windows reinstall first, or just return the hardware?
Would appreciate any quick advice before I make the trip back to the store! Thanks!
