What local AI models can the AMD Radeon RX 6650 XT run?
37 of our 115 models, up to NVIDIA Nemotron 3.5 Bolt E4B. That is the largest current model that fits the Radeon RX 6650 XT's 8 GB at Q4 with room for about 46K tokens of context (its full 64K with 8-bit KV cache), at about 35 tok/s estimate.
Memory type: GDDR6 (source) · Bus width: 128-bit (source) · Released: 2022 (source)
- RDNA 2: no calibration point; uses the AMD constants fitted on RDNA 3/3.5/4.
Specs from first-party pages (AMD), accessed 2026-10-18. Speeds use the AMD (ROCm/Vulkan) constants (how).

Q4_K_M unless the row says otherwise; UD- sizes are unsloth dynamic quants, the only Q4 build published for those models. Max context is an estimate of the longest context whose KV cache fits beside the model: default FP16 cache, then 8-bit (q8_0).
Speed calculator
estimateEstimate = bandwidth ÷ GB read per token (the model's listed GGUF file: Q4_K_M for most models, otherwise the quant named in the list; scaled by active/total parameters for MoE), scaled by a per-platform efficiency and fixed per-token costs calibrated to 45 measured llama.cpp benchmarks (2025–26). Fit = file size + 1.5 GB headroom ≤ total VRAM (on Macs, the part of unified memory macOS lets the GPU use by default), and room for at least 4K tokens of context with an 8-bit KV cache. For a model with no KV cache data, only the file and headroom are checked, so a fit says nothing about context. Multi-GPU: VRAM adds, speed stays one card's (a layer split runs the cards in turn); max context uses the total. Speed is for short context. Max context = what is left after the file and a 1 GB runtime reserve ÷ KV cache bytes per token, default FP16 and 8-bit (q8_0) cache. How speed works · how context works
