Nvidia wants to make your Windows PC an agentic and creator powerhouse
Why it matters: Nvidia just announced what it calls the most efficient PC chip ever built. RTX Spark is a Grace Blackwell system on a chip, 70 billion transistors on TSMC 3nm, with a Blackwell RTX GPU, a 20-core Arm CPU built with MediaTek, and up to 128GB of unified memory. It is purpose-built for agents, and it runs full RTX gaming and creation on the same thin-and-light laptop. It is a genuinely impressive piece of silicon.
Nvidia still dominates, but AI demand is lifting the rest of the chip market
Bottom line: Demand for AI infrastructure has been reshaping how investors value chipmakers, and recent results from key suppliers have strengthened the view that compute-intensive workloads will continue to grow. The effect has been evident with CPU vendors as of late. AMD's stock traded at $278 on Thursday, putting its market value at about $454 billion. Intel's rally from early March pushed the stock toward $68 and lifted its market cap to just under $340 billion. Arm's shares, meanwhile, traded close to $165, valuing the company at roughly $174 billion.
In context: Arm-based laptops typically lag in the GPU department – after all, unlike x86, the platform isn't known for its gaming performance. But that may soon change. Nvidia has been working with MediaTek on an Arm-based SoC featuring a GPU that could rival the RTX 5070. The chip, reportedly called the N1, is impressive given that it integrates the CPU and GPU into a single package.
