As part of a (Japanese) writeup on the subject, Impress Watch posted a video from inside a factory showing how a Zotac RTX 2000 series graphics card is assembled. It doesn't show the fabrication of the core or memory itself, which would happen at a foundry somewhere else, but assembling and testing the PCB still looks like a massively complicated process. PCGamesN has an excellent (English) writeup on the long process if you want more. Otherwise, check out the video here. Unmute it at your own peril. Production of the product is done at the factory of PC Partner which is the parent company of ZOTAC, the location is Dongguan, Guangdong province, China. It is done consistently here from test manufacturing to packaging. The parts mounting on the board is almost fully automated, and users wanting to worry about how the latest video cards are being manufactured should check them out.... Also, test production of prototype, performance test of cooler, test of noise, various durability tests etc. are done here, impression that quality control is also thoroughly done.
