Local LLM calculator
The best local LLM for your AMD graphics card
From the RX 7600 to the RX 9070 XT: the strongest model that fits each card's memory, and how fast it writes.

Estimates, not measurements, computed from public llama.cpp benchmarks. Figures reviewed on September 26, 2026.
The card's memory decides which models fit: 16 GB runs models of 14 billion parameters or gpt-oss-20b; the 24 GB RX 7900 XTX, 32 billion.
llama.cpp runs Radeon cards through Vulkan: writing is fast; reading long documents is slower than on NVIDIA cards.
Twoody for Windows and Linux is in private beta: on Windows 10 and 11 (x64), it runs the model on a Radeon card through Vulkan when the driver supports it, and on the processor otherwise; on Linux, on the processor. The speeds on this page are those of LM Studio or Ollama, not measured with Twoody.
Questions about running an LLM locally
Which LLM for a Radeon RX 7900 XTX?
With 24 GB, Qwen3 32B or Gemma 4 31B fit at 4-bit, and mixtures of experts such as gpt-oss-20b write very fast.
What fits in 16 GB of VRAM?
Models of up to 14 billion parameters at 4-bit, or gpt-oss-20b, with room for a long conversation.
Does Twoody run on Linux with an AMD card?
In the private beta, Twoody runs on Linux (x86_64), but on the processor: it does not use the graphics card there. On Windows 10 and 11 (x64), it uses a Radeon card through Vulkan when the driver supports it. Leave your email on the platforms page to join the waitlist.
