Eh… not quite. Maybe on an Instinct. Unified memory means the CPU and CPU means they can do zero copy to use the same memory buffer.
Many integrated graphics segregate the memory into CPU owned and GPU owned, so that even if data is on the same DIMM, a copy still needs to be performed for one side to use what the other side already has.
This means that the drivers, etc, all have to understand the unified memory model, etc. it’s not just hardware sharing DIMMs.
