NVIDIA RTX Spark: 128GB Unified CPU–GPU Memory
NVIDIA unveiled the RTX Spark "superchip" around Computex/Build 2026. RTX Spark pairs a 20-core Grace CPU with a Blackwell RTX GPU connected via NVLink‑C2C into a single 128GB coherent memory pool, removing host↔device PCIe copies for zero‑copy CPU–GPU access. The Blackwell GPU is described with 6,144 CUDA cores and fifth‑generation FP4 Tensor Cores, and NVIDIA cites up to 1 petaflop of low‑precision (FP4) peak AI compute. Consumer NVLink‑C2C bandwidth is undisclosed. NVIDIA positions RTX Spark for on‑device AI agents and large context models; laptops and compact desktops from ASUS, Dell, HP, Lenovo, Microsoft Surface and MSI are expected to ship RTX Spark systems in fall 2026. The release highlights reduced PCIe transfer overhead rather than eliminating memory bandwidth limits entirely.
Major hardware release from NVIDIA enabling zero‑copy unified CPU–GPU memory reduces PCIe transfer bottlenecks and materially affects on‑device LLM inference and agent deployment for edge and client devices.

Nvidia Unveils RTX Spark SoC for Windows PCs
Nvidia announced the RTX Spark, a System-on-Chip (SoC) designed for Windows devices, at Computex. The chip combines CPU and GPU on a shared memory architecture with configurations from 16 GB up to 128 GB of unified RAM. Nvidia positions the GPU performance near an RTX 5070 while delivering lower power consumption. RTX Spark includes around one petaflop of AI compute, which Nvidia says is sufficient to run local AI agents with models of ~120 billion parameters. Microsoft showcased a Copilot‑Plus Surface Laptop Ultra using the chip; Nvidia and partners (Acer, Asus, Dell, HPT, MSI, Lenovo) are reportedly working on 30+ laptops and 10 desktops with RTX Spark. Nvidia and Microsoft expect device shipments in fall 2026, with exact pricing and final launch dates not yet disclosed.
Nvidia launches RTX Spark AI chip for Windows PCs
Nvidia announced the RTX Spark, a System-on-Chip (SoC) for Windows devices unveiled at Computex. RTX Spark combines CPU and GPU on a single chip, with Nvidia claiming GPU performance roughly equivalent to an RTX 5070 while using less power. The SoC supports shared unified memory with configurations up to 128 GB and includes about a petaflop of AI compute — which Nvidia says is sufficient to run 120-billion-parameter models locally. Microsoft showcased a Copilot‑Plus device, the Surface Laptop Ultra, alongside the chip. Nvidia expects RTX Spark and Surface Laptop Ultra to ship in Fall 2026; it and partners are reportedly working on 30+ laptops and 10 desktops from OEMs including Acer, Asus, Dell, HPT, MSI and Lenovo.
Nvidia Unveils RTX Spark CPU for AI Agent PCs
CNBC’s Jim Cramer said Nvidia CEO Jensen Huang’s Computex keynote reinforced the view that AI compute spending creates winners beyond Nvidia. Cramer highlighted companies Huang named — Arm Holdings, Oracle, Nebius and CoreWeave — and noted those stocks rallied after the keynote. The piece also references Nvidia’s announced full-scale entrance into the personal-computer market and Cramer’s view that investors should hold Nvidia alongside hyperscalers Amazon and Alphabet. This article comments on market reaction (Nvidia +6%; Oracle, Nebius and CoreWeave rose sharply) and frames the keynote as a defense of heavy AI infrastructure spending. The article is reporting on the same Computex keynote where Nvidia unveiled a new RTX Spark CPU aimed at local AI/agent workloads (the Computex product announcement is recorded in recent signals).
