Looks like they're meant to be an affordable consumer workstation GPU, that can also game. The whole tariff business might even be enough to make these cards more attractive than the alternatives.
Also, I haven't kept up in the news regarding crypto mining in China, but it was pretty huge there for awhile. They did compare their GPU's to one of Nvidia's most popular cards, which happens to be the most popular mining card...
If you want to get the tinfoil hats going, consider that China is releasing a new "cryptocurrency," and a GPU supplier for their military is now offering cheap new cards. They've stated that people won't be able to mine this new currency, but what if your GPU came preinstalled with a low resource crypto miner? Sell enough of them and...no, their government would never do that right?
