All high end GPUs use DDR5 for their vRAM. Some lower end GPUs will use slower DDR3 vRAM.

As far as I know, dedicated cards don't use and virtual memory.

On the other hand, integrated graphics do share the system RAM and I suppose could be forced to use virtual memory if your RAM was completely used up. The performance would be awful tho.

If you are asking if you can replace the RAM with a graphics card, no.

If that's not what you're asking, I have no idea what you are asking.

This is a RAM kit:

This is a Graphics Card:

RAM is used by the CPU to store data that is currently being worked on, because reading/writing on RAM is orders of magnitude faster than using a HDD.

The graphics card is a specialized processor that handles all graphics output. Dedicated graphics cards (like the one pictured above) have RAM built in to them specifically for the graphics processor to use. Since graphics workloads then to be memory intensive, this RAM is usually faster than normal desktop RAM (DDR5 for GPUs vs. DDR3 for desktops).
