Apparently, AMD has placed a long black sticker on the lower left corner, seemingly to remove mentions of Taiwan. That appears to be convenient timing as the new 7600X3D chips are slated for release in China on September 20, and the country has a history of forbidding mentions of Taiwan on product packaging.
