An intrepid modder has managed to hook up an Nvidia RTX 3090 graphics card to a laptop by connecting it to the pocket book’s M.2 slot, which is designed to play host to an SSD, not a GPU.
This feat was achieved by an worker of Chinese agency Koshin, which is a subsidiary of Lenovo, and it leads to a absolutely practical system succesful of dealing with some severe gaming – like working Cyberpunk 2077 ‘smoothly’ with ray tracing turned on.
As noticed by PC Watch, the modder confirmed off this setup utilizing a Koshin Air 14 laptop powered by a Ryzen 5 4600 U processor.
The M.2 NVMe SSD was taken out of the pocket book, to permit the RTX 3090 to be related to the laptop utilizing an M.2 to PCIe adapter cable (with the small matter of requiring a gap to be lower within the underside of the laptop chassis to run the cable out to the GPU).
Then there was the issue of powering this exterior graphics card, of course, and to do this, the RTX 3090 needed to be hooked up to a desktop PSU (650W mannequin), making this, let’s say, a lower than elegant trying answer.
The efficiency achieved is spectacular, although, as we talked about, however clearly not on the identical degree as you’d get with the 3090 in a desktop PC.
In the top, whereas that is a largely impractical endeavor, it’s an fascinating piece of tech wizardry nonetheless (albeit not the primary time this type of answer has been applied – although it’s the first time we’ve seen it).
Normally, the way you’d hook up an RTX 3090 (or different graphics card) with a laptop can be as an exterior GPU in an enclosure via a Thunderbolt connector, which is clearly a a lot simpler way to go.
The M.2 slot technique is a cool thought, theoretically providing efficiency advantages above Thunderbolt 3 – assuming you will get all of it to work okay – however the primary stumbling block is that we might undoubtedly not suggest you begin slicing holes in your laptop your self, for apparent causes.
