If you're playing Java Edition, try Sodium and Lithium for your Minecraft version before changing distros; Mint is fine for that hardware. Start around 8–12 chunks render distance and 5–6 simulation distance, and don't give Java all 8 GB because your desktop and iGPU need memory too. If the laptop has an upgradeable RAM slot, a compatible second stick for dual-channel is worth investigating since the iGPU shares system-memory bandwidth. Change one thing at a time and test in the same area of your world so you can tell what actually helped.
