Nvidia RTX Spark brings powerful Arm chips to Windows PCs
Nvidia has launched RTX Spark, a chip for high-end Windows laptops and other PCs.
It combines Arm processor cores, Blackwell graphics and shared memory on one chip, with configurations offering up to 128GB.
The design targets local AI work, allowing models and other demanding tasks to run on the computer rather than in the cloud.
The chip can also handle gaming and creative work, and reviewers found its graphics performance especially strong.
Its high price limits its appeal: the least expensive machines mentioned cost $2,700, and reviewers say most gamers can find better-value options.
RTX Spark is aimed more at developers and mobile creators who need strong graphics and AI performance, particularly while away from a power outlet.
More RTX Spark computers are due from six hardware partners, with systems beginning to ship this week.
RTX Spark combines an Arm CPU, a Blackwell GPU and up to 128GB of unified memory in a system-on-chip for high-end Windows computers.
A Windows Central review found strong graphics and AI performance, while describing CPU results as good overall but behind some leading chips.
The GPU handles demanding games, rendering and local AI workloads, with performance that can approach dedicated RTX 4070- or 5060-class graphics in many non-AI tasks.
The reviewers said RTX Spark is best suited to developers and mobile content creators who use local AI or other GPU-heavy applications.
Power use can rise sharply under heavy GPU load, although the system can maintain performance on battery, according to the articles.
