AMD Ventures has taken a stake in Turing, a Japanese self-driving startup, and Turing has begun running about 10% of its AI training workload on AMD graphics processors instead of Nvidia's, company executives told Bloomberg. AMD shares jumped roughly 3% in premarket trading Monday the moment the news broke, according to TipRanks. Turing built its AI systems entirely on Nvidia hardware since it launched five years ago, but AMD offered a real chance to diversify supply and cut costs, the executives said. The company still plans to reach consumers and robotaxi fleets by 2028, according to Bloomberg, and raised $79 million in an equity and debt extension last year that valued it near $600 million. Turing also partnered with auto supplier Denso last year to help it move toward commercial production, according to a Nikkei Asia report. Separately, Goldman Sachs raised its price target on AMD to $640 from $450 Monday, and Citi added the stock to its upside catalyst list, according to Investing.com. The stock surged from a low of $527.04 to hit $556.64, with the rally also sparked by reports of delays to Nvidia's Kyber rack system, a claim Nvidia has since pushed back against.
