Exclusive-Intel, AMD sign long-term server CPU deals with Chinese clients as prices surge, sources say

U.S. chipmaking giants Intel and Advanced Micro Devices are signing longer-term purchase commitments with Chinese server customers for data-centre processors as prices ‌surge, two people familiar with the talks said. The move highlights a broader consequence of the ‌AI boom: demand has spread beyond AI accelerators to memory, networking gear and server processors, giving suppliers greater leverage to seek long-term purchase ​deals.
