No. I've been reading up. I'm planning to run Flux 12b on my AMD 5700G with 64GB RAM. CPU will take 5-10minutes per image which will be fine for me tinkering while writing code. Maybe I'll be able to get the GPU going on it too.

Point of the OP is this is entirely possible with even an iGPU if only we have the RAM. nVidia should be irrelevant for local inference.
