Software woes hit Air India Express as flight cancellations resume

Samsung Electronics’ latest high bandwidth memory (HBM) chips have yet to pass Nvidia’s tests for use in the US firm’s AI processors due to heat and power consumption problems, three people briefed on the issues said.

The problems affect Samsung’s HBM3 chips, which are the fourth-generation HBM standard currently most used in graphics processing units (GPUs) for artificial intelligence, as well as fifth-generation HBM3E chips that the South Korean tech giant and its rivals are bringing to market this year, they said.
