Server makers building machines for Microsoft, Google and Oracle have started telling those customers that systems containing Nvidia's AI chips will cost more than 15 percent extra in many cases, on gear shipping from early 2027. The increases cover the flagship Vera Rubin and Grace Blackwell systems, and vary by chip generation and memory configuration. The stated cause is not Nvidia's silicon but the DRAM around it: memory prices have surged as Samsung, SK Hynix and Micron fail to keep up with AI demand. Nvidia did not comment.
