Microsoft and NVIDIA posted matching teasers on X with the line “A new era of PC,” alongside the coordinates “25.0528, 121.5990,” which point to the Nangang Exhibition Centre, the venue for Computex 2026. NVIDIA is expected to unveil its N1X client PC processor, with Microsoft backing it for Windows 11 Artificial Intelligence PCs and full Copilot+ acceleration. The chip is widely expected to help NVIDIA challenge Qualcomm’s Snapdragon X2 Elite series for leadership among Arm-based Windows processors, with performance aimed at high-end x86-64 PCs from Intel and AMD.
NVIDIA is allegedly building the N1X on the TSMC 3 nm foundry node. The latest leaks describe a 20-core processor using an Arm big.LITTLE design with 10 performance cores and 10 efficiency cores. All 20 cores are said to be custom-designed by NVIDIA and based on the Arm v9.2 machine architecture. The CPU complex is expected to include 32 MB of shared last-level cache, underscoring NVIDIA’s ambition to deliver a premium client processor for advanced Windows systems.
The chip’s most notable feature is an integrated GPU that is also expected to function as an NPU. Based on the “Blackwell” graphics architecture, the iGPU is expected to feature up to 48 streaming multiprocessors (SM) for 6,144 CUDA cores, with performance possibly comparable to the discrete GeForce RTX 5060 Ti. NVIDIA is also expected to pair the chip with an LPDDR5X interface and a unified memory architecture, creating a design focused on both graphics and on-device Artificial Intelligence workloads.
NVIDIA’s stated goal is to outclass Apple M5 Pro and AMD Ryzen Artificial Intelligence Max 400. The positioning suggests an aggressive move into premium Arm-based PCs, where NVIDIA is aiming to combine CPU, graphics, and neural processing in a single platform for Windows 11. Intel is not described as having a direct rival in this category, unless it moves toward chips with large integrated GPUs based on its Xe3 “Celestial” architecture.
