Microsoft and Nvidia took the stage together in San Francisco on October 7 to unveil the Surface Laptop Ultra, a premium 15-inch Windows laptop powered by Nvidia's RTX Spark — the chipmaker's first Arm-based processor built for Windows PCs. The machine starts at $2,599 and ships October 16, with a companion $5,999 Surface RTX Spark Dev Box mini PC arriving in November.

Nvidia plans to take a stake in d-Matrix, a Santa Clara startup that designs chips for AI inference, The Information reported on October 8. The investment, whose size and valuation were not disclosed, is part of a broader Nvidia strategy to make its technology interoperable with rival silicon rather than fighting every inference workload alone.
