NVIDIA and MediaTek co-developed the technology behind RTX Spark, and MediaTek identifies TSMC as its manufacturing partner for the project. NVIDIA brings the RTX graphics and AI platform. MediaTek contributes CPU, memory, power and connectivity engineering. TSMC brings the chip-manufacturing side. Together, that work puts an Arm CPU, Blackwell graphics and shared memory inside the laptops carrying the N1X name.
How those parts work together drives the buying decision. A large local AI project needs usable memory as well as GPU power. An editing setup needs compatible applications, plug-ins and peripherals. Understanding the chip’s design helps you read a laptop’s specifications and ask the right questions before spending your money.
NVIDIA supplies the RTX and AI foundation
NVIDIA’s May 31, 2026 announcement describes RTX Spark as a combination of Blackwell RTX graphics, a Grace CPU and the company’s NVLink-C2C connection between them. It also explicitly credits MediaTek’s collaboration on the custom CPU design.
That’s the platform name. N1X identifies the processors listed in NVIDIA’s laptop specifications. Both laptop tiers carry that name: one has an 18-core CPU and 5,120-core GPU, while the higher tier has a 20-core CPU and 6,144-core GPU. Their supported memory ceilings are 64GB and 128GB, respectively. The exact configuration deserves a close look even when…
