For years, local AI image generation meant NVIDIA. That has changed. Here is the state of things in September 2026, with sources.
AMD Radeon
ComfyUI added official AMD support on Windows in version 0.7.0 (January 2026), built on AMD's ROCm; its README now installs AMD's multi-architecture PyTorch packages on ROCm 10. AMD's own ROCm list for Windows includes the RX 9000 series and the RX 7900 XTX, 7900 XT, 7900 GRE, 7800 XT, 7700 XT and 7600. It does not name the RX 7600 XT, but ComfyUI's Windows instructions still cover it, along with RDNA 2 cards. On Linux, ROCm has worked for longer.
Intel Arc
PyTorch supports Arc A-series and B-series GPUs natively (the "XPU" device) on Windows 11 and Linux, and ComfyUI documents that route officially.
What this means for the verdicts here
Whether a model fits depends on memory, and memory works the same on every brand. So the fit verdicts apply to AMD and Intel too. What differs is speed and the extras. RX 9000 (RDNA 4) GPUs have FP8 hardware that ComfyUI uses with ROCm 6.4+; on RX 7000/6000 and Intel, FP8 files are converted back before the maths, so they save memory but not time. Some custom nodes are written for NVIDIA only.
That is why the 24 GB RX 7900 XTX and the 16 GB RX 9070 XT are interesting: a lot of memory for the money. Expect more setup, and check that the custom nodes you rely on support your GPU. RX 7900 XTX vs RTX 4090 →
