SHANGHAI (Reuters) -China's Huawei Technologies showed off an AI computing system on Saturday that one industry expert has said rivals Nvidia's most advanced offering, as the Chinese technology giant seeks to capture market share in the country's growing artificial intelligence sector. The CloudMatrix 384 system made its first public debut at the World Artificial Intelligence Conference (WAIC), a three-day event in Shanghai where companies showcase their latest AI innovations, drawing a large crowd to the company's booth. The system has drawn close attention from the global AI community since Huawei first announced it in April.
