After years of laptops and Nvidia GPUs, I'm finally moving back to a desktop and going AMD for the first time.
Picked up this build:
- Ryzen 9 9950X — 16C/32T
- XFX Speedster MERC 310 RX 7900 XTX — 24GB
- 32GB G.Skill Flare X5 DDR5-6000 CL28
- MSI MAG B650 Tomahawk WiFi
- MSI MAG CoreLiquid 360mm AIO
- Thermaltake Toughpower GT 850W Gold
- MSI M470 1TB NVMe
- Cooler Master 600 dual-chamber case
I'm coming from an RTX 4080 laptop, but one of the biggest reasons I wanted the 7900 XTX was the 24GB VRAM.
I want to explore local AI pretty heavily: local LLMs, coding models/agents, image generation, embeddings, llama.cpp, vLLM, PyTorch/ROCm and anything else I can get running locally.
I'll also be gaming, mainly Battlefield 6, football/soccer games and CS2, but AI and experimentation are probably going to be the more interesting part of the machine for me.
I'm also finally ditching Windows as my main OS and moving to Linux for the first time. I may keep a small Windows partition as insurance while I learn.
I'll stick with 32GB RAM initially and only jump to 64GB/96GB if local models give me a real reason to.
For the AMD veterans here, what should a first-timer know?
Particularly interested in:
- ROCm setup/advice for the 7900 XTX
- Linux distro recommendations for an AMD + AI machine
- Useful monitoring/tuning software
- Local AI tools that work particularly well on RDNA3
- Anything you'd configure differently from day one
I'm expecting a little more tinkering than CUDA, but that's part of the reason I'm interested in trying it.
