Which should you buy?
The RX 9070 XT has 16GB of VRAM against 12GB on the RTX 5070, which leaves more room for local AI models, but many local AI tools are built around NVIDIA CUDA, so confirm that your runtime supports AMD GPUs before choosing the Radeon card. In this catalog, the RX 9070 XT has the lower median recorded price ($939.00 against $949.49). The lowest recorded price per GB of VRAM is $50.94 for the RX 9070 XT. Memory capacity does not measure speed, and these are recorded Amazon US quotes rather than live checkout prices, so confirm the current offer, condition, exact board and your power supply before buying.
Use the LLM VRAM estimator to check how much memory your model needs, then compare listings on the RTX 5070 page and the RX 9070 XT page.
