NVIDIA and MediaTek Launch RTX Spark Superchip for Next-Gen Arm Laptops

RTX Spark

NVIDIA has officially entered the PC processor market with the RTX Spark, an Arm-based superchip developed in collaboration with MediaTek. Announced at Computex 2026, this new platform combines a 20-core NVIDIA Grace CPU with a Blackwell architecture GPU to challenge the dominance of traditional x86 processors from Intel and AMD. The first laptops featuring the RTX Spark are expected to arrive in Fall 2026 from major manufacturers including ASUS, Dell, HP, and Lenovo.

The hardware specifications of the RTX Spark represent a significant shift for consumer laptops. By utilizing TSMC 3N process technology, the chip integrates 6,144 CUDA cores and fifth-generation Tensor Cores capable of 1 petaflop of AI performance. This power is supported by up to 128GB of LPDDR5X unified memory, which allows the system to handle demanding on-device AI agents and local 12K video editing. The CPU and GPU communicate via an NVLink-C2C interconnect, providing a massive 600 GB/s of bandwidth.

Performance and Efficiency Gains

NVIDIA and MediaTek have designed the RTX Spark to scale dynamically across different power envelopes. The chip can operate at single-digit wattage for basic tasks or ramp up to 80W for high-performance workloads. According to NVIDIA, this efficiency enables 1440p gaming at 100fps in laptops as thin as 14mm. Because the architecture is highly efficient, these machines are designed to maintain high performance levels even when running on battery power.

The ASUS ProArt series will be among the first to adopt the new silicon. ASUS confirmed that its upcoming RTX Spark lineup will focus on creative professionals who require high-precision FP4 computing for AI tasks. Other partners confirmed to launch hardware this fall include MSI, Acer, and Gigabyte. This broad industry support suggests a major push to establish Arm-based Windows PCs as a standard for both gaming and professional creative work.

As of June 2026, the RTX Spark is positioned as a direct competitor to the latest offerings from traditional chipmakers. By bringing Blackwell-class graphics and Grace CPU architecture to the mobile segment, NVIDIA aims to redefine the capabilities of thin-and-light laptops. Consumers can expect the first retail units to hit shelves in the third quarter of this year.
