By that point, the startup was only a year and three months old. The company’s AI accelerator Ion turned out to be 30% faster at processing than Intel Corp.’s Habana Goya. Not only that, Ion’s electric consumption rate is much lower than that of its Intel counterpart. Prior to Ion, Habana Goya was the fastest AI accelerator in this field.
