Hi,
The video course also has a link to laptops used
Laptop Guide for Architecture and Design - 2022-2023 EDITION - YouTube
The comparison
The NVIDIA RTX A1000 Laptop GPU or A1000 Mobile is a professional graphics card for mobile workstations. It is based on the GA107 Ampere chip and offers a slightly slower performance than the consumer GeForce RTX 3050 Laptop GPU.
Yes it will 5.4 and it will do the Arch Viz course.
Depends what you try to make in future!!
