I could in theory upgrade the power supply to go beyond the 150W target, but then I’d also need a better chassis because it is already quite warm with my current 130W card.
Hoping to stick with AMD, but if my wishes to play around with local LLMs and image upscaling makes Nvidia a more practical choice, I can live with that compromise.
Working with a budget of 200 US, I’m fine going with a used GPU.
You’re gonna have to go a few years back to hit all the goals you have, but a 3060 12gb or even 3070 if you can get one under your price point is gonna have at least 12gb of ram, be near your tdp, maybe over but you can set a power limit, allow you to work with llms and have good linux support.
The newer the line, the better the rocm, but I think the base 9060 is like 8GB 160W $250
Just bought at used Radeon RX 7600 8GB on eBay for $185.

What is your current card? The RX 6600 is comfortably within your requirements but has just 8GB of RAM, and the RX 6700 is just at the edge or slightly outside of your budget with 10GB of ram, which you could probably make work if you find a good deal and undervolt it. On Nvidia’s side there’s the 3050 8GB and 3060 12GB.
RX 480, thinking of upgrading since ROCm support for it ended a while ago and working around it has become very painful
If your big issue is just getting back into mainstream support, you can try looking for a 7600, since RDNA 3 is just one generation removed from the latest. You’ll have to undervolt or limit power and you’ll be stuck with 8GB on that budget but you’ll probably receive software support for slightly longer than the RDNA 2 6600/6700.
RX 7600, comes in 8gb and 16gb variants. GL getting anything that isn’t ancient for under $200
This is the GPU that I have in my main rig. It’s awesome. Link.
