Nvidia Enters PCs With MediaTek-Designed N1X Chip on TSMC 3nm

Nvidia is entering the Windows PC market with RTX Spark, an Arm-based platform built on the N1X processor it co-designed with MediaTek, according to TrendForce. The flagship pairs a 20-core CPU with a Blackwell GPU on TSMC's 3nm process. Over 30 notebooks and 10 desktops from Dell, HP, ASUS, and Lenovo are due in fall 2026.

This matters because Nvidia is pushing into a layer long owned by Intel and AMD, and it cannot do it alone. The chip needs a CPU design partner and a leading-edge foundry.

Both are Taiwanese. MediaTek does the design and integration; TSMC does the silicon. Taiwan supplies the parts no one else can.
