Nvidia on Friday posted a cryptic social media post that seemed to give credence to rumors that the company will make a chip for Windows PCs and announce it at the chipmaker’s GTC Taipei convention next week. The post read “A new era of PC,” and then listed two numbers which appear to be the coordinates of the Taipei Music Center. Huang’s presentation is slated to begin on Monday at 11 a.m. Taipei time, which is Sunday at 11 p.m. U.S. Eastern Time.
