Looking for AI PC recommendation to replace my old laptop

I've been using old laptop as personal use since 2008 and it hasn't been working properlyrecently. (shortage battery, insufficient ram and lag while watching online strem)

Now I am considering to purchase a AI model instead, but i am wondering should i upgrade RAM instead or just buy a new one? Requirement:

- 16GB ram / 1TB SSD / Individual Graphic Card / Fingerprint
