Best local LLMs for the AMD RX 6700 XT

Speed

computed band 15.0-37.0 tok/s for 8B Q4_K_M (roofline, 384 GB/s VRAM); community: 25-40 tok/s 7B Q4 (kb-audit-0903)

Effective decode window: 0.20–0.50 of 384 GB/s nominal → ~77–192 GB/s effective (llama.cpp decode, Q4_K_M basis; card-specific window from cited community benches)

Community check — localmaxxing.com medians (1 bucket): localmaxxing.com

→ ~38 tok/s · 12-15B Q4 · 4 runs · above our band — small sample; documented outlier, computed window stands

What fits (computed)

→ 13b-q4 offload-partial 14.6 GB vs 12 GB usable — partial CPU offload, expect large speed loss

→ 3b-q4 full 2.8 GB needed of 12 GB usable — headroom for context

→ 4b-q4 full 3.7 GB needed of 12 GB usable — headroom for context

→ 8b-q4 full 6.1 GB needed of 12 GB usable — headroom for context

Gotchas

⚠ Software tax is heavy: unofficial ROCm, Linux >> Windows

⚠ Ollama-on-ROCm inconsistent vs llama.cpp HIP

⚠ Buy only at a deep discount, and only if terminally patient with setup

⚠ Band basis: card-cited rows (LocalScore floor 16.4, guides 25-40) imply eff 0.22-0.47 of 384 GB/s — gfx1031 unofficial ROCm never reaches the 6800-class window; eff_override set 0905.
