NVIDIA RTX Spark Specs, Features, and Release Date

Quick answer

NVIDIA RTX Spark is a new Arm-based system-on-a-chip (SoC) launching in fall 2026. It merges a 20-core Grace CPU with a Blackwell-architecture RTX GPU (6,144 CUDA cores) and up to 128GB of unified memory. Designed to reinvent Windows PCs, it delivers 1 petaflop of AI performance for local agents, creative workloads, and 1440p gaming in an ultra-efficient, slim form factor.

The Superchip comes to Windows

For years, NVIDIA dominated the dedicated GPU market, while Apple’s unified silicon reshaped what thin-and-light laptops could achieve. Announced at Computex Taipei in June 2026, NVIDIA RTX Spark is the company’s direct answer to the unified memory revolution — and it brings the entire NVIDIA software stack along for the ride.

RTX Spark is not just a mobile graphics card; it is a full SoC combining both the central processor and graphics processor onto a single package, utilizing TSMC's 3nm node. By pairing an efficient Arm-based Grace CPU with a powerful Blackwell RTX GPU, NVIDIA is bringing the architecture from its enterprise DGX supercomputers into consumer laptops like the Microsoft Surface Laptop Ultra.

Memory architecture

Why unified memory changes the game

Traditional gaming laptops split memory between system RAM (for the CPU) and VRAM (for the GPU). This split forces the system to constantly copy data back and forth over the PCIe bus, causing latency and bottlenecking performance when VRAM limits are exceeded.

RTX Spark features up to 128GB of unified memory. The CPU, GPU, and NPU all access the exact same memory pool simultaneously. Because the GPU can address up to 128GB directly, creators can load massive 90GB 3D scenes in OptiX without crashing, and AI developers can run massive 120-billion-parameter local models that would normally require multiple expensive desktop graphics cards.

Gaming capability

Gaming performance: Will it replace dedicated GPUs?

While RTX Spark is marketed heavily towards AI and creation, it is fundamentally an RTX product. With 6,144 CUDA cores based on the cutting-edge Blackwell architecture, its raw rasterization power is roughly equivalent to a mobile RTX 5070.

  • 1440p Gaming: NVIDIA claims smooth 100+ FPS experiences in modern AAA titles at 1440p resolution.
  • Full RTX Stack: Because it runs native CUDA, the chip fully supports hardware-accelerated Ray Tracing, DLSS 4.5 (including Frame Generation), and NVIDIA Reflex.
  • No VRAM anxiety: With access to the massive unified memory pool, gamers will never encounter the stuttering issues associated with 8GB VRAM limits in modern titles.
