These responsibilities complement GPU-accelerated inference and training rather than replacing them.

🎤 Jensen Huang and Rene Haas Share the Stage

#

One of the most memorable moments of the keynote came from the informal conversation between Rene Haas and Jensen Huang.

The two industry veterans exchanged jokes about Arm’s soaring valuation and NVIDIA’s historic relationship with the company.

Huang humorously remarked that every NVIDIA product launch seems to benefit Arm’s stock price more than NVIDIA’s own.

The conversation eventually shifted to NVIDIA’s failed attempt to acquire Arm.

Revisiting the Arm Acquisition Attempt

#

Reflecting on the proposed merger, Huang acknowledged that NVIDIA had worked extensively toward combining the two companies.

Although the acquisition ultimately did not receive regulatory approval, Huang jokingly admitted that he still regrets the missed opportunity.

The exchange highlighted the close strategic relationship between the two companies despite remaining independent entities.

A Touch of Nostalgia

#

To conclude the discussion, Haas presented Huang with a Microsoft Surface RT powered by NVIDIA’s Tegra 3 processor.

The device represented an important milestone in Arm computing history as one of the earliest mainstream Arm-based computing platforms.

The gesture served as a reminder of how long both companies have been investing in Arm’s future.

💻 NVIDIA’s Vision for the AI Agent PC

#

The conversation soon moved from industry history to future computing architectures.

Haas challenged Huang with several questions regarding AI agents and the future of personal computing.

The responses revealed NVIDIA’s long-term vision for AI-native systems.

🤖 Why NVIDIA Built RTX Spark

#

According to Huang, the traditional PC architecture has remained fundamentally unchanged for decades.

AI agents are expected to alter that model significantly.

Future systems will increasingly rely on autonomous software capable of:

• Using applications directly
• Executing workflows
• Performing research
• Managing complex tasks
• Interacting with digital tools on behalf of users

To support this paradigm, NVIDIA designed the RTX Spark platform around Arm technology.

RTX Spark Highlights

#

Key specifications include:

• Custom 20-core Arm CPU
• Blackwell GPU architecture
• Unified memory subsystem
• Native Windows on Arm support
• Up to 1 PFLOPS of FP4 AI performance

The platform is optimized for local AI processing while maintaining compatibility with cloud-based services.

NVFP4: Compressing Models for Local Execution

#

A significant challenge for AI PCs is fitting large language models into system memory.

To address this, NVIDIA introduced NVFP4, a new numerical format designed to:

• Reduce model size
• Improve memory efficiency
• Enable local execution
• Preserve inference quality

This approach allows increasingly sophisticated AI models to run directly on client hardware.

☁️ Balancing Edge AI and Cloud Computing

#

One of the most interesting themes discussed during the keynote was the relationship between local AI processing and cloud services.

Huang emphasized that future AI agents will operate continuously, even when users are away from their devices.

Potential scenarios include:

• Sending requests to a home PC remotely
• Delegating research tasks
• Running local workflows
• Managing documents autonomously

The general principle is straightforward:

• Execute locally whenever possible
• Use cloud APIs only when necessary

This hybrid model reduces latency, improves privacy, and lowers cloud computing costs.

🖥️ Why Operating Systems Still Matter

#

As AI agents become more capable, some analysts have argued that traditional software applications may become less relevant.

Huang strongly disagreed with this perspective.

Software Is Not Disappearing

#

Most users only utilize a small fraction of available software functionality.

AI agents can potentially unlock the remaining capabilities by learning how applications operate.

Future agents may interact with software through:

• Model Context Protocol (MCP)
• Command-line interfaces
• Application APIs
• Structured documentation
• Native operating system services

Rather than replacing software, AI agents are expected to increase software utilization.

The Continuing Importance of Windows and OS Platforms

#

Operating systems remain essential because they provide:

• Security
• Resource management
• Application interfaces
• Hardware abstraction
• System services

AI agents ultimately depend on these capabilities to perform meaningful work.

As a result, operating systems may become even more important in an AI-centric computing environment.

📈 The Real Constraint: Compute Demand

#

When asked about future industry bottlenecks, Huang pointed to one overriding challenge: demand.

According to NVIDIA, computational demand continues to grow faster than available supply.

The Economics of AI Tokens

#

The modern AI economy increasingly revolves around token generation.

As AI systems become more autonomous, they consume significantly more compute resources because they:

• Read documents
• Evaluate options
• Cross-check results
• Execute workflows
• Call external tools
• Maintain long-term context

A simple chatbot query may require relatively few tokens.

An autonomous agent performing a multi-step workflow may require orders of magnitude more computational resources.

This dynamic is driving unprecedented demand across the entire AI infrastructure stack.

🧩 The Rise of Arm-Based Custom Silicon

#

One of the strongest themes at Computex 2026 was the industry’s growing commitment to custom Arm silicon.

Several major technology companies have already deployed proprietary Arm-based processors.

Examples include:

Rather than relying solely on merchant CPUs, many organizations are designing processors tailored to their specific workloads.

⚙️ Arm’s Compute Subsystem Strategy

#

A key enabler of this trend is Arm’s Compute Subsystem (CSS) approach.

CSS provides a modular framework that allows partners to combine:

• Custom CPU designs
• GPU technologies
• Interconnect fabrics
• System IP blocks

This architecture accelerates development while preserving flexibility.
