The AI Local Check Verdict: Which GPU should you buy for AI?
The Classic Headroom vs Speed Trade-off: The NVIDIA RTX 4060 Ti 16 GB has 4 GB more VRAM, allowing it to fit larger models that cannot run locally on the NVIDIA RTX 5070.
However, the NVIDIA RTX 5070 has a higher memory bandwidth (672 GB/s vs 288 GB/s). For models that comfortably fit in 12 GB VRAM, the NVIDIA RTX 5070 will generate tokens roughly 133.0% faster. Choose the NVIDIA RTX 4060 Ti 16 GB if you prioritize model size flexibility, or the NVIDIA RTX 5070 if you prioritize token generation speed on models up to 12 GB.
