Depends on task at hand. Had Asus vivabook with Ryzen 5600h and it was fast enough for everything except gaming well you could still play indie games and light games no problem.

Value wise PS5 will last you good 5 years. Keep it just get a laptop with i5 or Ryzen 5 that supports NVME and 16GB DDR4. 2x8.

Don’t mix different speed and size RAM sticks. Keep it dual channel ideally 2x8 3200Mhz if laptop supports it.
