The entire thing: Pre-training, training, inferencing — the works,” said Phil Fersht, founder and chief analyst at HFS Research, a global business research consultancy.
“Google and TPUs are being seen as the first credible competition to Nvidia’s GPUs, reflecting in Google stock rocketing up and Nvidia one getting depressed,” he said.
