Microsoft and Nvidia Look to Reinvent the PC for the Agentic Era

By Bob O'Donnell

When the likes of Microsoft CEO Satya Nadella and Nvidia CEO Jensen Huang are chatting onstage together, you’re bound to get big picture vision statements and bold claims. In the case of PCs, a field in which both have worked and had tremendous influence over many decades, that is particularly true.

Indeed, at yesterday’s big Microsoft-Nvidia launch event, Huang stated, with Nadella’s strong confirmation, that the new Surface Laptop Ultra, and all the new Windows-based PCs running Nvidia’s RTX Spark chip, portend the reinvention of the PC, marking the dawn of the agentic PC era.

Only time will tell whether that proves to be true, but in the moment, the story was undoubtedly intriguing—and maybe even a bit convincing. What the two companies laid out was a rethinking and repositioning of PCs’ capabilities, thanks to a combination of important changes to Windows, the powerful advancements of Nvidia’s latest chips, and the dramatic rise in AI foundation models and agentic software tools.

Together, these elements are now aligning in a way that enables the processing and productivity that was available only in the cloud-based frontier models of just one year ago to fit into a form factor you can carry with you or fit into a tiny box on your desk. That, in turn, is driving a whole new conversation about the potential for impressive amounts of token-generating work to be performed directly on the device, without having to pay for those tokens (except, of course, when considered as a fraction of the device’s purchase price).

Even more importantly, this combination dramatically increases the probability of creating hybrid AI solutions that can leverage a combination of on-device processing and some from the cloud. There’s no question that we’ll always need to use the most advanced cloud-based frontier models for certain tasks, but it also seems abundantly clear that we don’t need to use them for everything. Splitting the work across those environments—as well as enterprises’ own on-prem AI factories—makes the most sense for a multitude of reasons, including economic, security, privacy, and just plain logic. (See “How Tokenomics Might Save AI PCs” for more.) That’s why hybrid AI is such a compelling solution and why it was arguably the overall focus of the event.

However, the star of the show was the new Surface Laptop Ultra, priced at $2,599 for the base configuration of 24 GB of RAM/512 GB of storage/18 CPU cores/5,120 GPU cores but reaching up to $5,899 for the top-end 128 GB of RAM/1 TB of storage/20 CPU core/6,144 GPU core setup. (Interestingly, the company is offering up to a $1,000 rebate if you trade in an eligible Macbook Pro.) The Surface Ultra features a super-bright 1000 nit, 15” touchscreen OLED display along with a clever new magnetic USB-C port connector for its power adapter. Impressively, Microsoft’s spec sheets say the units will have up to 15 hours of battery life playing video and up to 12 hours of “active web usage.” The new PCs will be able to run local AI models with up to 120B parameters, depending on the amount of system memory installed. In addition, Microsoft unveiled the pricing for its previously announced developer-focused Surface RTX Spark Dev Box, which features 128 GB of RAM/2 TB of storage/20 CPU cores/6,144 GPU cores for $5,999.

In addition to Microsoft’s own systems, the two companies showed off forthcoming RTX Spark-based notebooks from Asus, Dell, HP, Lenovo, and MSI and small desktop form factors from Dell and Asus, all of which are expected to start shipping around October 16 (as will the Surface Laptop Ultra). Unlike the previous DGX Spark systems, which use Nvidia’s GB10 chip and run Linux, the new small desktops, Surface Dev Box, and all the new laptops run Windows 11 on Nvidia’s N1X chips.  While details are still forthcoming, the GB10 and N1X family are apparently architecturally similar to each other, and all offer 1 petaflop of FP4 AI performance. In addition, both Dell and HP showed off forthcoming high-end workstations, capable of running Windows, that will incorporate NVidia’s GB300 Grace Blackwell Ultra Desktop Superchip.

Along with impressive AI capabilities, Microsoft also touted the gaming capabilities of its new Nvidia-powered laptop. The company announced support for Gears of War and many other popular gaming titles available at launch, as well as Call of Duty coming in 2027. What’s particularly interesting about this development is that it highlights an easily overlooked impact of Nvidia’s entry into the Windows PC market with the N1X family. As with their data center CPUs, these Nvidia chips are all based on the Arm CPU architecture designed by MediaTek, meaning these are Windows on Arm devices. Up until now, gaming support for Qualcomm’s Snapdragon X family of Arm-based PCs has been challenged, but with Nvidia entering the market, many game developers who may have initially balked at the effort to port their games from X86 now have a good reason to do so. As a result, all Windows on Arm-based devices, including the Qualcomm Snapdragon X-based systems, will benefit from these efforts. This is also true for all the Windows enhancements that Microsoft debuted at the event, so it’s a case of raising all boats.

The new Windows features will also be coming to x86-based systems, particularly Copilot+ PCs. That’s important, because despite all the initial hardware focus, some of the most impactful announcements from the event were these additions and enhancements to Windows. As Windows and Surface lead Pavan Davaluri explained, the company is working to make Windows the most secure platform for agents, as well as the heart of a hybrid intelligence computing experience.

Given all the recent stories about agents running amok, the security story for Windows is particularly noteworthy, because it’s designed to build the trust that’s going to be necessary for individuals and businesses to run agents. The company’s new Microsoft Execution Containers, or MXCs, safeguard people and their data by both putting the agents into separate containers and controlling which files and networks they can access. This capability is designed to ensure that agents can run safely on Windows. All the major agentic tools, including OpenAI’s Codex, OpenClaw, Nvidia’s OpenShell, and the newly announced Muse for Windows, among others, will be supporting it. Interestingly, for small desk-side AI computing devices, Microsoft is also adding a simplified wizard and integrated Windows gateway that makes the process of setting these devices up as AI companion agentic computers dramatically easier.

On the hybrid intelligence side, by flipping a single switch setting in Windows, Microsoft is enabling a raft of new features that will make your computer just seem smarter. Doing so gives Copilot permission to access your local files and activity to give it the context it needs to do work on your behalf. In addition, it can run local actions either via manual control or by leveraging the further enhanced Autopilot agent now built into Windows. The new Actions in Windows Search feature—which I expect to be the one thing announced at this event that virtually every Windows user will benefit from—extends this concept by allowing you to simply type action requests into the Windows search bar and have it execute them for you. From switching Windows settings, to organizing files, sending a text message and more, this is the kind of Windows intelligence many have been waiting for. Finally, the hybrid intelligence switch enables Windows to easily tap into local models you can download and run on your PC, making the often-confusing task of configuring those models much easier.

A critical part of the overall hybrid AI computing concept is doing the routing between on-device and cloud-based models. Microsoft is starting its efforts with developers by bringing GitHub’s HydraFusion into Windows. This can automatically select which coding tasks can be done with on-device models and which need to be sent to the cloud. Hopefully we’ll see more of this intelligent AI model routing spreading across additional Windows-based applications and activities in the future.

There’s no doubt that the capabilities now possible with PCs have evolved more over the last few years than they have in a very long time. Whether that really means the category has been reinvented is still up for debate, but it’s undeniably great to see companies across the PC ecosystem coming together to help our computers become as smart, capable, and useful as we always thought and hoped they could be.
