I recently discovered, in a brief discussion with kos, that Nvidia does not produce its own graphic cards (apart from Quadro series), but other manufacturers are producing and selling them (Zotac, EVGA, Gigabyte, ...).
So, it's rather easy (
lshw) to know the chipset of your graphic card, but Google didn't help us in find a way to know the manufacturer.
Why should someone be interested in it?
Because depending on the manufacturer we have different clocks, different cooling systems, different capabilities.
So, how can we know the manufacturer/producer from Ubuntu?
Is there an equivalent command of
dmidecode for GPUs?
Other ideas that do not involve physically opening the computer and look for hints there?
