Models with a thinking mode spend extra tokens thinking, so their speed thresholds are 1.5× stricter (30 / 12 / 3 tok/s). With thinking turned off, a model may do one grade better.

The system RAM share above also counts the 0.90 GB MTP (multi-token prediction) block, which llama.cpp does not load by default, so it errs on the safe side. Turning on MTP speculative decoding (llama.cpp --spec-type draft-mtp) loads that block and needs KV cache for it too.

S = Runs great · A = Runs well · B = Runs slowly · F = Won't run
At Q4_K_M the verdict stays Runs well up to 64k context with an f16 KV cache, and up to 128k with q8_0.
Estimated speed
- Generation
- est. 43.6 tok/s (30.5–56.6, theoretical estimate ±30%)
- Prompt processing
- Prompt-processing estimates only apply when the whole model runs on the GPU.
Why this verdict: Not fully on the GPU — Runs great needs the whole model in GPU memory
Measured on this exact combination
No public measurement for this exact combination yet; the numbers above are estimates.
If this is not enough
Keep only the experts in system RAM
--n-cpu-moe 31 keeps only the experts of the first 31 layers in system RAM and everything else on the GPU (this estimate).
How to run it
Commands for the Q4_K_M file. Both tools download from Hugging Face on first run.
These commands assume 32 GB of system RAM. For a different amount of RAM, pick it under “System RAM, context length and KV cache” above to see the commands for it.
File: Qwen_Qwen3.6-35B-A3B-Q4_K_M.gguf (22.29 GB) from bartowski/Qwen_Qwen3.6-35B-A3B-GGUF.
llama-server -hf bartowski/Qwen_Qwen3.6-35B-A3B-GGUF:Q4_K_M -c 8192 -ngl all --n-cpu-moe 31 -fa on- -ngl all loads every layer on the GPU.
- --n-cpu-moe 31 keeps the experts in the first 31 layers in system RAM; the remaining 9 layers with experts keep them on the GPU. This estimate assumes the same split.
- If loading fails with an out-of-memory error, raise the value to 32, or to 33 if that isn't enough.
- llama.cpp b7410 (December 2025) and later split the model in a similar way on their own if you leave out -ngl and --n-cpu-moe.
- -fa on enables flash attention (needed for KV cache quantization).
- --cache-type-k q8_0 --cache-type-v q8_0 shrinks the KV cache to 0.09 GB at 8k context.
PowerShell (quit the Ollama tray app first):
$env:OLLAMA_CONTEXT_LENGTH="8192"; ollama serve
ollama run hf.co/bartowski/Qwen_Qwen3.6-35B-A3B-GGUF:Q4_K_M- Ollama defaults to 4k context on GPUs under 24 GB. Set OLLAMA_CONTEXT_LENGTH when starting the server, or /set parameter num_ctx inside the chat.
- Ollama 0.30 and later automatically keep part of the experts in system RAM to fit your VRAM. Older versions split whole layers instead, which is much slower.

Frequently asked questions
Can I run Qwen3.6 35B-A3B on the GeForce RTX 4060?
Q4_K_M keeps attention and the experts of 9 layers on the GPU (7.3 GB) and the remaining experts in 16.3 GB of system RAM: Runs well, est. 43.6 tok/s (30.5–56.6, theoretical estimate ±30%). Q4_K_M needs 21.8 GB at 8k context; this setup has 7.4 GB of usable memory and 28.0 GB of free system RAM.
How much context can Qwen3.6 35B-A3B use on the GeForce RTX 4060?
At Q4_K_M the verdict stays Runs well up to 64k context with an f16 KV cache (1.3 GB of KV) and up to 128k with a q8_0 KV cache (1.4 GB). The model supports up to 256k.
Which quant should I use, and how fast is it?
Q4_K_M (22.29 GB) is the recommended balance: Runs well, est. 43.6 tok/s (30.5–56.6, theoretical estimate ±30%). It is also the largest tracked file that gets this verdict.
Speeds are estimates from memory bandwidth, calibrated against public benchmarks, and each one comes with an error band and a confidence label. Real results vary with drivers, backend, context length and thermals.
