That's evident from the revenue that the chip designer generates from its data center segment each quarter, which is significantly more than its rivals generate in an entire year.

To be clear, Nvidia’s graphics processing units (GPUs) remain the gold standard for the AI industry.

Nvidia is seeing massive demand for its new Blackwell chips, which are more powerful than the Hopper line, and it plans to roll out the next-generation Rubin chips next year.
