Why such a big difference in prices for laptops?

Question

laptops

I'm looking for a laptop from HP.
There are 2 models. The only difference between them is the amount of RAM and SSD.
The first laptop - 16GB of RAM, 256GB of SSD, 130 thousand rubles.
The second - 32GB of RAM, 512GB of SSD, 150 thousand rubles.
That is, the difference is 20 thousand rubles.
Somehow too much.
Let's say installing a 512GB SSD instead of 256GB is an additional 4k.
Then it turns out that 32GB of RAM instead of 16GB is an additional 16 thousand rubles ???
