Qwen3.6-35B is 35B total / 3B active, 262,144 tokens on the official card. Llama 3.3 70B is 70.6B, 128K tokens. Q6 / Q5 / Q4 file sizes come from the listed GGUFs on each /models page, or a calculator estimate when a listing is missing. Q3 stays off. Q4 fits Qwen3.6-35B on one R9700 at 4K and spills on Llama 3.3 70B. Qwen3.6-35B has measured llama.cpp cells on the local desktop. Llama 3.3 70B speed is not measured yet. llama.cpp first.
How we test
— Measured cells cite official amdai-bench/run@1 cards. Estimates stay labeled. Q3 is estimate-only. Q1/Q2 stay off.
Official card: 35B total / 3B active, 40 layers, 10 full-attention (GQA 2×256). Only those 10 layers grow a token-length KV cache. The other 30 hold a fixed linear-attention state.
Existing GPU sheets only: R9700, RX 7900 XTX, RX 7900 XT, RX 7800 XT. llama.cpp, f16 KV.
Totals are calculator estimates. Speed is measured only on R9700 35B cells that already exist;
everything else stays not measured yet. This table lists Q6 / Q5 / Q4. Q3 stays on the calculator as a labeled estimate.

Qwen3.6-35B holds Q4 on one R9700 at 4K. Llama 3.3 70B needs RAM offload.
Coding agents
Coding agents want the file in VRAM and a stable llama.cpp server. The house daily-driver recipe is measured on the R9700 for Qwen3.6-35B. Llama 3.3 70B is 70.6B — size Q4 on the calculator before you assume that recipe applies. We do not invent an agent decode figure for Llama 3.3 70B.
Long context
Cited context is 262,144 tokens vs 128K tokens. KV grows with context. Q4 at 32K fits Qwen3.6-35B and spills on Llama 3.3 70B on one R9700. Read /long-context for measured R9700 35B 128K–262K cards. We do not invent a 128K decode figure here.
Size and VRAM
Qwen3.6-35B files: Q6_K 26.7 GB, UD-Q5_K_XL 26.6 GB, Q4_K_M 19.8 GB. Llama 3.3 70B files: Q6_K 57.89 GB, Q5_K_M 49.95 GB, Q4_K_M 42.52 GB. Fit on the four existing GPU sheets below. Empty speed cells stay not measured yet.
