What is this?

[Megazero]

I was kinda bored so I go on the only online shopping website I know about in my place and type the word "GPU" to see what it will show, and I got these. What is this?

Copper Plates, I guess.

Copper heatsinks for mobile GPUs (and, presumably, CPUs as well)

Heatsink? Isnt it too small for that? Plus for laptop wont it have to connect to a bigger pipe and to the fan near the edge of the laptop?

It's a copper shim, they are used to full the gap between a cpu/gpu die and a heatsink.

These were used on some HD7950/7970s with aftermarket coolers or water cooling blocks.

From Wikipedia:

 

A CPU shim (also called CPU spacer) is ashim used between the CPU and the heat sink in a computer. Shims make it easier and less risky to mount a heatsink on the processor because it stabilizes the heatsink, preventing accidental damaging of the fragile CPU packaging. They help distribute weight evenly over the surface.

 

(So they are like heat spreaders for old CPUs that had exposed die to heatsinks.)

So they use this on top of the thermal paste or to replace the thermal paste all together?

On top of

I'd do on top of thermal paste. You can also use them to help with non-flat, crappy heatsinks

most likely it'll go something like: CPU, thermal goo, shim, thermal goo, heatsink

This is correct.

 

Also you wouldn't use one unless absolutely necessary.

I could see a use for it for old CPUs that don't have a lid, but who the hell still uses those?

Most likely could be more commonly used on GPUs since those aren't lidded at all and you really want to ghetto cool it

for when cpu's and gpu's were just the dye thing, (gpu still like that) but now cpus have a plate on top to dissipate the heat
