NVIDIA's Arm chip delays not solely attributable to Microsoft, as Windows playing a role in the setbacks too
NVIDIA's much-anticipated Arm-based N1 series chips, initially expected to debut in Q3 2025, are now set to launch in late 2026, according to recent reports. The delay is attributed to a combination of hardware design challenges, software ecosystem readiness issues tied to Microsoft Windows Arm development, and market demand factors in the notebook segment.
Engineers encountered a major new hardware problem with the N1x chip, requiring a significant silicon redesign ("respins"), which has pushed back the launch timeline. Beyond the major hardware fix, NVIDIA continues to revise and improve the chip design, contributing further to delays.
The rollout of Microsoft's next-generation Windows on Arm OS is slower than initially anticipated, affecting NVIDIA's ability to launch chips that depend on a mature Windows Arm ecosystem. The overall reduction in notebook demand has led NVIDIA and partners like MediaTek to prioritize enterprise-class systems first, deferring consumer releases and reducing urgency.
The N1X and N1 chips, if introduced, would expand the offerings available to consumers on the Arm side of things, joining Qualcomm's range of Snapdragon X chips. The chips are rumoured to have TDP (Thermal Design Power) of 80W or 120W and are said to rival the performance of the RTX 4070 laptop GPU while being much more energy efficient.
If true, the N1 series could power slim and powerful gaming laptops that outperform Arm-based PCs powered by Qualcomm chips. Presumably, consumer and gaming-focused devices would follow. The details about the N1X and N1 chips are still subject to change, as reported by DigiTimes, due to the fluid nature of Microsoft's operating system roadmap and NVIDIA's chip revisions.
The introduction of the N1X and N1 chips could potentially power slim and powerful gaming laptops that outperform Arm-based PCs powered by Qualcomm chips. The latest reports suggest that the N1X and N1 chips could shake up the computing industry, providing fresh competition for Intel, AMD, Qualcomm, and Apple.
Microsoft is reportedly working to iron out kinks in Windows on Arm to prepare for NVIDIA's Arm chips. The first wave of NVIDIA Arm chips is expected to target enterprise users, with consumer and gaming-focused devices following potentially in the future. The N1X and N1 chips, if introduced, could be manufactured by MediaTek.

- The hard-earned silicon redesign for NVIDIA's N1x chip has extended the launch timeline, moving it from Q3 2025 to late 2026.
- The gaming industry may soon welcome gaming laptops that could outperform existing Arm-based PCs, should the N1 series of chips be introduced.
- Amidst hardware problems and Microsoft's Windows on Arm OS development, the N1X and N1 chips might first cater to enterprise users and later expand to consumers and gamers.
- The deployment of a mature Windows Arm ecosystem, critical for the chips' operation, has been slower than expected, impacting NVIDIA's plans.
- With rumors of TDP ranging between 80W and 120W, the N1X and N1 chips are said to offer performance comparable to the RTX 4070 laptop GPU while being energy efficient.
