[ELI5]Why Windows laptops back in 20007-2008 were so thick and heavy?

Question

When the hardware inside isn’t that different from todays laptops

In: Technology

Answer 1

Computers are a lot smaller now due to the manufacturing process. Around 2008, the manufacturing process for semiconductor devices was about 45nm. This means bigger chips, more heat, more cooling needed for the heat, etc.

Now, we’re ~5nm, so around 10x smaller.
