TL;DR Nvidia has the best performance. Qualcomm is matches Nvidia with performance per watt.

Every chip that can run models sells for profit, because demand is so much higher than supply. The difference is profit margin. Nvidia gets something 90% profit margin for their server chips because their performance is better. Others must adjust until their price/performance ratio matches Nvidias.

Next 1-2 years Nvidia prints money, but the money printing machines are owned by TSMC and their capacity for next few years is locked in.
