For your use case, I’d recommend looking at Lenovo ThinkPad P1 Gen 6 or Dell XPS 15/17 with an Intel i9 or Ryzen 9, 32–64GB RAM, and NVIDIA RTX 4070 or higher. If you’re open to de…

That’s an impressive collection. Definitely not basic! Love how practical these are for real-world ops work, especially the MySQL .ibd optimizer loop and swap memory check.
