AMD Radeon RX 6600
Entry RDNA 2. 8 GB VRAM, lower bandwidth (224 GB/s) — the bottleneck on AI. ROCm officially supported on Linux. ~30-45 tok/s on 7B Q4. Reasonable budget AMD entry but bandwidth-limited compared to the 6600 XT or 6700 XT siblings.
Extrapolated from 224 GB/s bandwidth — 22.4 tok/s estimated. No measured benchmarks yet.
Plain-English: Edge-of-fit for 7B; expect compromises.

The RX 6600 is for the operator who needs a low-power, budget-friendly ROCm card for light local AI experimentation on Linux. It runs 7B Q4 models at ~25-35 tok/s, which is usable for chat but not for real-time inference. 8 GB VRAM fits 7B models comfortably, but 13B models require aggressive quantization (Q3 or lower) and still risk OOM. The 224 GB/s bandwidth is the bottleneck—expect slower token generation than even the 6600 XT. Software stack is limited to ROCm on Linux; no CUDA, no Windows support. Pass if you need to run 13B+ models at decent speed, or if you want a plug-and-play experience on Windows. At $180 used, it's a cheap entry point, but the 3060 12 GB offers more VRAM and broader software support for not much more.
›Why this rating
The RX 6600 is a budget option for AMD ROCm on Linux, but its 8 GB VRAM and low bandwidth limit it to small models at modest speeds. It scores a 5.5 because it works for light workloads but is outperformed by similarly priced alternatives.
