This is a really important point. The architecture and the bus ram is connected to is also very different on on a discrete card than it is in a cpu. Each compute unit needs dedicated bus width connected to dedicated memory. So for most GPUs you can double the ram, but you couldn’t just add the equivalent of a stick of ddr5 because it wouldn’t match the dedicated bus
