RX 9070 XT vs RTX 5070 Ti for local AI (2026)
VRAM, memory bandwidth, today's prices (new, used and rental) and which local AI models each card can run.
Prices updated Nov 12, 2026The short version
- VRAM: both have 16 GB, so they fit exactly the same models.
- Speed: the RTX 5070 Ti has about 40% more memory bandwidth, so expect roughly 40% faster token generation on models that fit both (estimate; prompt processing and image generation depend on compute, not shown).
- Price: the RX 9070 XT is $474 cheaper today ($846 used vs $1,320 used); per GB of VRAM that's $53 vs $82.
- Software: RX 9070 XT: ROCm/Vulkan - works in llama.cpp & Ollama; image/video tooling less mature. RTX 5070 Ti: CUDA - best support in llama.cpp, vLLM, ComfyUI.
