The event is set for 10 AM PT on Wednesday, and the teasers have been deliberate. Microsoft's Windows account posted that “something new is coming from Windows,” while Nvidia shared its own teaser pointing to fresh hardware announcements.
Microsoft says the show will feature “RTX Spark and new experiences designed to unlock more possibilities for developers and builders.”
What RTX Spark actually is
RTX Spark combines a 20-core Nvidia Grace CPU with a Blackwell-generation integrated GPU containing 6,144 CUDA cores, connected through NVLink-C2C so both halves of the chip can address up to 128GB of unified LPDDR5X memory.
That single pool is the platform's headline feature: a conventional laptop divides memory between system RAM and graphics memory, while RTX Spark lets one large pool serve AI models, video timelines, and 3D scenes that would exceed the VRAM of ordinary mobile GPUs.
Nvidia advertises up to one petaflop of low-precision AI performance and support for running models with up to 120 billion parameters locally. The platform keeps Nvidia's familiar software ecosystems, including CUDA, TensorRT, DLSS, and Reflex.
Microsoft has already adapted Windows 11 for the architecture with a Workload Profile Scheduling system and a tuned Prism emulation layer for running x86 apps on the Arm-style design.
Which machines to watch
The most likely star of the show is the Surface Laptop Ultra, which Microsoft announced in June 2026 without revealing a price or release date.
Nvidia has already named six initial laptop designs built on RTX Spark: the Asus ProArt P16, Dell XPS 16, HP OmniBook Ultra 16, Lenovo Yoga Pro 9n, Microsoft Surface Laptop Ultra, MSI Prestige N16 Flip AI+, and Grey Box Shifter.
Separately, Asus is teasing its ProArt 16 creator laptop with the RTX Spark N1X processor for an October debut, according to TechPowerUp.
The first wave is aimed squarely at creators, developers, and professional users rather than gamers, even though Nvidia's gaming software stack carries over. Microsoft has also shipped a Surface RTX Spark Dev Box aimed at developers building AI applications locally.
Local AI is the bet
The event is really a test of Microsoft's bigger thesis: that complex AI models should run on the PC itself rather than in the cloud. Microsoft and Nvidia are positioning local AI as the foundation for software agents that can organize files, summarize documents, and execute multi-step workflows directly on the device.
It is also Microsoft's second big swing at the AI PC after the mixed reception of its Copilot+ PC push in May 2024. Independent benchmarks, final pricing, and retail availability are all still unknown, so October 7 is a checkpoint rather than a verdict.
But with both chief executives on one stage, the industry will be watching to see whether on-device AI finally gets its defining hardware moment.
