Computex briefings put RTX Spark and agentic AI into the centre of Windows on ARM, forcing a rethink of consumer PC economics as OEM launch plans, software rewrites and early share moves signal a new phase in chip competition.
Computex is resetting expectations for what a Windows PC looks like in the next upgrade cycle. Merifund Capital Management is tracking Nvidia’s push to put its RTX Spark platform at the centre of that shift, extending reach beyond data centres into everyday consumer machines.
Nvidia is positioning RTX Spark as a foundation for Windows laptops and compact desktops, with the reference configuration presented at the show delivering up to 1 petaflop of AI performance. More than 30 laptop designs and 10 desktop systems are slated for the autumn launch window, giving hardware partners a clear timetable for product planning.
The proposition is direct: combine ARM CPU cores with Blackwell-class graphics and a unified memory pool scaling to 128GB in the platform specification circulated at Computex, then run demanding AI tasks locally rather than sending each interaction to the cloud. That raises the ceiling for on-device creation tools and automation, while testing whether Nvidia can translate data centre economics into a consumer form factor where power, heat and cost discipline shape margins.
Microsoft is adjusting Windows to support agentic AI functions that treat natural-language prompts as system commands, wrapped in security controls designed to keep agents inside user-authorised applications and data. MediaTek is working alongside Nvidia on custom CPU design and connectivity, and further detail is expected at Microsoft’s Build developer event later this quarter.
Initial plans feature systems from ASUS, Dell, HP, Lenovo and Microsoft’s Surface line, with more models expected as production ramps. Reference designs target premium machines around 14 millimetres and about 3 pounds, alongside compact desktops aimed at creators and developers who want local inference without a workstation footprint.
In its portfolio assessment, the firm focuses on whether consumer PCs provide diversification without eroding pricing power. For Merifund Capital Management Pte. Ltd.’s Anthony Saunders, who is director of private equity, RTX Spark is “strategic optionality in a business where one engine can dominate expectations”. The latest reported quarter puts the data centre segment at roughly 90% of revenue, compared with about 25% five years earlier, while the gaming segment sits near 6% after about 51% in the equivalent quarter five years earlier.
Windows on ARM remains shaped by Qualcomm’s long exclusivity arrangement and modest traction. Shipment trackers put Snapdragon X laptops at roughly 0.7 million units in a recent third-quarter period, equal to about 0.8% of global PC shipments in that same quarter. A separate research projection keeps ARM-based PCs below 13% share across the most recent full calendar year, even as Intel’s Lunar Lake narrows the battery-life gap that tends to favour ARM systems.
Pricing sharpens the choices for buyers. AMD’s Strix Halo systems list between $2,545.8 and $2,767.2 on current retail schedules, against Nvidia’s own compact desktop reference system from about $4,426.4. One market forecast expects ARM-based notebooks to rise to 25% share over the next two annual buying cycles, from an estimated 14% over the preceding four quarters.
Software support becomes the swing factor as launches approach. Adobe is rebuilding Photoshop and Premiere Pro for native compatibility, and demonstrations released with the platform briefing show AI-assisted editing running at up to 2 times the baseline speed on identical project files. For gaming, DLSS 4.5 launch tests point to gains of up to 35% in the 4K path-traced showcase sequence used in briefing benchmarks.
Equity markets react quickly to the strategic signal. Over the two trading sessions immediately following the keynote, Nvidia shares trade 6.2% higher, while Intel and AMD move 6% and 5% lower respectively, and Qualcomm falls 8.7%. Microsoft rises 3% over the same window as investors focus on the Windows integration angle.
Saunders points to “the grind of drivers, power curves and developer adoption over multiple release cycles” as the real determinant of outcomes as the category matures. Against a global laptop market running at about 150 million units in a typical annual cycle, the prize is scale, but consumer thermal limits, component costs and competitive intensity keep execution risk high.
For Merifund Capital Management, the investable milestones come into view over the coming quarters as prototype performance, native application readiness and end-product pricing show whether RTX Spark becomes a repeatable consumer platform for the autumn launch window rather than a one-off showcase.
