Graphics functionality != display output What about laptop GPUs, which don't necessarily output to the screen at all times. Sometimes they don't even have a capability to do so. If it's coprocessor working alongside the general processor for the primary purpose of accelerating graphics computing workloads, it seems appropriate to call it a GPU.

Edit: perhaps your point is that it doesn't make sense to call a device designed primarily to accelerate ML workloads or just general purpose vector calculations. In that case I'd agree that GPU isn't the right name.
