Nvidia has unveiled its latest artificial intelligence chips, which the company claims are far more powerful than its existing market-leading hardware, as it sets its sights on extending its domination of the burgeoning industry.

Chief executive Jensen Huang on Monday said Nvidia’s Blackwell graphics processing units will massively increase the computing power driving large language models. The Blackwell GPU has 208bn transistors, compared with last year’s H100, which has 80bn, a measure of its increased power.

Huang said the chip was twice as powerful when it came to training AI models as its current generation of GPUs, and had five times their capability when it came to “inference” — the speed at which AI models such as ChatGPT can respond to queries.
