Gpu recommendation for beginner level ML and AI workloads

I'm building my first pc and I'm into ai and ml workloads. Shall I the rtx 5060 to (16gb) or rtx 5070 (12gb)? The 5060 ti has more vram so I'm confused. (Also I don't think AMD cards perform good in AI workloads compared to nvidia, correct me if I'm wrong)
