China's first homegrown GPU company. More threads now reading a public debut in Shanghai, founded by some former Nvidia employees who are now looking to take on the US chip giant. Our dude Debosa has some details in today's tech check.Hey D. >> Hey, good morning Carl. So investors while they're gaming out the Google TPU threat to Nvidia, the real blind spot may be on the other side of the world.China, yes, it's building its own GPU stack and more threads IPO. It's 4,100 times overs subscribed. That's the ne ...
