Chinese online stores tend to carry graphics cards based on Nvidia's laptop graphics processors, but some are coming to market with cracked GPUs. The sellers clearly state that these are mobile GPUs with lower performance and power consumption than their desktop counterparts. But where do they get these graphics chips? Since some of these GeForce RTX 4080M/GeForce RTX 4090M GPUs come with cracks, experts from PRO Hi-Tech believe that they may well come from scrapyards.
Graphics cards are popular and in high demand. With plenty of manufacturers around, getting components for add-in cards, including printed circuit boards (PCBs), is relatively easy. Perhaps the hardest part is getting graphics processors; after all, these are the most expensive parts of graphics cards. Some GPUs can be obtained from a distributor, but these companies sell in significant quantities, and small shops do not deal with significant quantities. So, they use other options, like buying defective laptop motherboards with GPUs, which were meant to be destroyed but ended up on various internet auctions, as well as motherboards that have qualification samples.
