What it says

  • Reservations for RTX Spark laptops opened on October 7, availability starts on October 16 and compact desktops arrive in November. Manufacturers include Acer, ASUS, Dell, HP, Lenovo, Microsoft, MSI and Gigabyte, and the Surface Laptop Ultra is built on this chip.
  • RTX Spark combines a Blackwell GPU of up to 6,144 cores with a Grace CPU of up to 20 cores, linked at 600 GB/s. It offers up to 128 GB of unified memory and one petaflop of AI performance at FP4.
  • According to NVIDIA, Microsoft announced at the same event the general availability of Microsoft Execution Containers (MXC), the operating system infrastructure that lets AI agents run in the background under the user's control.
  • NVIDIA previews a DGX Station for Windows with GB300, 748 GB of coherent memory and up to 20 petaflops of AI at FP4. According to the company, it is enough to run models of up to one trillion parameters locally. Until now it only worked with Linux. No price or date has been given.

Our take

Until now, running large AI models locally required a Linux workstation or the cloud. With 128 GB of unified memory in a Windows laptop, part of that workload can stay on the employee's machine, next to their data. If you are renewing equipment this year, wait for the prices: NVIDIA's note does not give them yet.
