But threats to Nvidia's reign are rising

Rivals Intel (INTC) and AMD (AMD) are marshaling their forces to grab their own slice of the AI pie.

In December, AMD debuted its MI300 accelerator

which is designed to go head-to-head with Nvidia's own data center accelerators.

Its share of the global AI chip market is estimated at anywhere between 70% and 90% 

Nvidia (NVDA) is the AI king 

Patrick Moorhead, CEO of Moor Insights & Strategy, said,

"Nvidia started working with universities about 15 years ago to invent new things,

"What you could do with a GPU besides gaming and visualization."

because by the time they've caught up, Nvidia is on to the next new thing,”
