Qwen3.8 27B

Runs well27BAlibaba QwenApache 2.0 license

Qwen3.8 27B (27B) fits comfortably in the R9700's memory at Q6_K, using about 25GB with 8K context and generating ~18 tokens/sec. It is the most capable model in our catalog that runs well on this card. It is also our top pick for coding, reasoning and working with images.

Qwen3.8 27B, released in August 2026, is one of the strongest open models that fits a single 24GB GPU, with image input, a 262K native context, and switchable thinking. It uses the same hybrid layout as the Qwen3.5 and 3.6 27B models, where three of every four layers use linear attention, so long contexts cost far less memory than on older dense models. At Q4_K_M it needs about 18GB with 8K context, leaving room for 64K or more of context on a 24GB card, and 32GB cards can run Q6_K. It supersedes Qwen3.6 27B and Qwen3 32B, but its long reasoning traces make speed on slower hardware a real consideration.

Qwen3.6 35B-A3B

Runs well35B (3B active)Alibaba QwenApache 2.0 license

Qwen3.6 35B-A3B (35B (3B active)) fits comfortably in the R9700's memory at Q5_K_M, using about 28GB with 8K context and generating ~78 tokens/sec. It is the next-best model that runs well here, and the one to try if the top pick doesn't suit you. It is also our top pick for speed. It is also the largest model that runs fully on this GPU.

Qwen3.6 35B-A3B is the April 2026 refresh of Qwen's fast mixture-of-experts model, focused on agentic coding and on preserving its reasoning across multi-turn tool use. With only 3B active parameters it generates text very quickly, and its hybrid linear attention keeps the KV cache tiny: the full 262K context needs about 5GB. At Q4_K_M it needs about 24GB with 8K context, which is tight on a 24GB card and comfortable on 32GB GPUs and Macs with 36GB or more; 12GB to 16GB GPUs run it well with experts offloaded to system RAM. It replaces Qwen3 30B-A3B and Qwen3 Coder 30B-A3B for most local users.

Limits

Popular models that don't run well on 32GB

  • gpt-oss-120b
    Partial offload

    Needs about 68GB at MXFP4 with 8K context. It will run with 56% of the weights in system RAM at about 23 tokens/sec with CPU offload, which is usable because only a fraction of a mixture-of-experts model is active per token. See what hardware it needs.

  • Needs about 168GB at FP4 with 8K context. It does not fit, even with CPU offload. See what hardware it needs.

  • GLM-5.3-Flash
    Won't fit

    Needs about 201GB at Q4_K_M with 8K context. It does not fit, even with CPU offload. See what hardware it needs.

  • Qwen3.5 122B-A10B
    Partial offload

    Needs about 77GB at Q4_K_M with 8K context. It will run with 61% of the weights in system RAM at about 10 tokens/sec with CPU offload, which is usable because only a fraction of a mixture-of-experts model is active per token. See what hardware it needs.

Setup

Best settings and software for the R9700

Radeon support has improved a lot, but expect a little more setup than on NVIDIA. With Qwen3.8 27B at Q6_K, you can fit roughly 91K tokens of context with a 16-bit KV cache; an 8-bit KV cache about doubles that.

  • LM Studio or Ollama: both support Radeon through ROCm or Vulkan.
  • llama.cpp (Vulkan): often the least-friction backend on AMD and very competitive on speed.
  • llama.cpp (ROCm/HIP): fastest prompt processing on supported cards under Linux.
  • vLLM (ROCm): for multi-user serving on supported Instinct and Radeon PRO cards.

New to quantization? Q4_K_M is the safe default; read our quantization explainer to see when Q5, Q6, or Q8 is worth the extra memory.

Frequently asked questions

What is the best LLM for the R9700?

Qwen3.8 27B is the best all-round model for the R9700. At Q6_K it uses about 25GB with 8K context and generates ~18 tokens/sec.

What quantization should I use on the R9700?

Use the highest-precision quant that leaves room for your context. Q4_K_M is the best default: it is about a quarter the size of the original 16-bit weights with only a small quality loss. If a model fits at Q5_K_M, Q6_K, or Q8_0 with room to spare, use that instead. Avoid going below Q3 except for very large models.

How much context can I use with Qwen3.8 27B on the R9700?

At Q6_K with a 16-bit KV cache, roughly 91K tokens fit in 32GB. Quantizing the KV cache to 8-bit (for example with llama.cpp's --cache-type-k q8_0 --cache-type-v q8_0) roughly doubles that.

Can the R9700 run gpt-oss-120b?

Only with partial CPU offload. At MXFP4 it needs about 68GB, so 56% of the weights would sit in system RAM and speed drops to about 23 tokens/sec with CPU offload.

Can the R9700 run DeepSeek V4 Flash?

No. DeepSeek V4 Flash needs about 168GB at FP4 with 8K context, which is far more than 32GB plus 64GB of system RAM.
