Nvidia slips as Google touts prowess of its own custom chips
BING-JHEN HONG

Nvidia (NASDAQ:NVDA) shares slipped more than 2% in premarket trading on Wednesday as Google (NASDAQ:GOOG) (NASDAQ:GOOGL) touted the capabilities of its own custom chips.
In a research paper available on the arXiv repository, Google (GOOG) (GOOGL) said the fourth-generation Tensor Processing Units, or TPUs, that train its artificial intelligence models are faster and more power-efficient than Nvidia's (NVDA) A100 chips. 
The custom chips are between 1.2 and 1.7 times faster than Nvidia's (NVDA) A100 chips, with up to 1.9 times more power efficient, Google (GOOG) (GOOGL) added.
Mountain View, California-based Google (GOOG) did not compare the fourth-generation TPUs to Nvidia's (NVDA) H100 chips because those came to market after Google's chips and use newer technology.
Alphabet (GOOG) (GOOGL), the parent company of Google, saw its shares rise 1% in premarket trading on back of the news.
Nvidia (NVDA) unveiled the first-generation H100 chips last year.
Last month, it showed off a new H100NVL at its annual GTC conference, amid several other AI-related announcements.
Nvidia (NVDA) CEO Jensen Huang recently said "the iPhone moment of AI has started," in reference to the number of AI-linked products and services that have taken the world by storm in recent months.
