"Fits in VRAM" = fast, fully on GPU. "Offload" = part on system RAM, slower. Speed is a rough estimate.
Frequently asked questions
What is the VRAM and memory bandwidth of the AMD Radeon RX 6800 XT?
The AMD Radeon RX 6800 XT features 16 GB of VRAM and a memory bandwidth of 512 GB/s (GDDR6). In local language model inference, VRAM determines which model sizes fit on the card, while memory bandwidth dictates how many tokens per second the GPU generates.
What is the best local AI model to run on a AMD Radeon RX 6800 XT?
The best overall model for the AMD Radeon RX 6800 XT is unsloth/Qwen3-Coder-30B-A3B-Instruct-GGUF using the recommended Q3_K_M quantization (14.88 GB total memory). With 16 GB of VRAM, this GPU typically runs a 14B at high quality, or a 24–27B at 4-bit at full GPU speed. Check our guide to the best LLMs for 16 GB VRAM for details.
Can the AMD Radeon RX 6800 XT run 14B and 32B models?
Yes. A 16 GB VRAM buffer allows you to run 14B models (like Qwen 2.5 14B or DeepSeek-R1 14B) in high-fidelity Q8_0 quantizations, or 32B models (like Qwen 2.5 32B) in Q3_K_M or Q4_K_M quantizations fully on the GPU.
Does the AMD Radeon RX 6800 XT work with Ollama and LM Studio?
Yes. Under Linux, the AMD Radeon RX 6800 XT supports native ROCm acceleration in Ollama and llama.cpp. On Windows, Ollama and LM Studio utilize the Vulkan or DirectML backends to leverage the card's full 16 GB VRAM pool.
