Video idea: use graphics card memory as swap

[gkillershots]

I found online resources that show that it is not impossible to use GPU memory as "System memory"

there are people that have RX480 or RX580 that have 8gb of VRAM, enough to run your entire OS into it

 

also, since they are faster, would this make it faster or slower?

There is a thread meant for video suggestions in LTT Official. You should post this there.

I'm not sure if it's doable on windows, but on linux it's pretty easy:

Even though it's somewhat fast, it's still way slower than your regular ram with awful latencies. I guess that if you have an nvme ssd there'd be no reason to do so.
