Why can't we use VRAM as system RAM? Why do we need DDR4?

>>61667425
The question is, why can't we use L3 cache instead of DDR4?

>>>/g/sqt

Because GDDR is meant for large continuous transfers and regular for all situations.

You can

Why can't we use the air inside the tower as RAM?

Why can't we use L2 cache?

Thanks to you, this is an Esoteric Kekkism thread now.

You can, it's called a RAMDISK.

latency.
that's the only reason.

>>61667425
You can use VRAM as a swap / page file in *nix... Just heard about this the otherday ... Still looking into the config files !

"VRAM" isn't different from normal system RAM.

GDDR5 is DDR3, for example.

They just use a different interface.

What about GDDR5X?

You can, it's just not practical if you want a paged memory model.

Small size and expensive.

Same as GDDR5 but with quad data rate.

>>61672601
And bandwidth.
