There are 2 video cards, what are the differences?

Question

Video cards

There are 2 laptops, the difference is only in the video card, Geforce 960m 2 GB ddr5 and Geforce 960m 4 GB ddr4, but, unfortunately, only differences between ddr5 and dd3 were found, but what to do in my case? What's the difference in performance?

Answer 1

there is less memory in one, but it is faster.
in other memory more, but it is slower.
You would at least voice your tasks / Wishlist.
if you are not going to play top games (and the laptop itself is not the best option for this), then it doesn’t matter at all, take whatever is cheaper.
