ASUS, Dell, HP, Lenovo, Microsoft and MSI have released laptops built on NVIDIA RTX Spark systems starting at $2,599, NVIDIA announced on Oct. 28. The laptops package an NVIDIA Blackwell RTX graphics processing unit and an NVIDIA Grace central processing unit into a single superchip.
The hardware architecture delivers up to 128GB of unified memory and up to one petaflop of FP4 computing power. NVIDIA stated that the systems measure down to 14 millimeters in thickness, weigh three pounds, and provide all-day battery life. Available configurations include touchscreens, digital pen support and two-in-one convertible designs. In creative workloads, the machines can edit camera-native 4:2:2 video and render 3D scenes up to 90GB, supported by beta versions of Adobe Photoshop and Premiere.
New models and system controls
NVIDIA introduced Nemotron 3.5 Transcribe on Hugging Face as an open-weight speech model. Operating with roughly 4.3 billion active parameters, the model ranks first on the Hugging Face Open ASR benchmark and second among open-weight models on Artificial Analysis. NVIDIA stated that the model requires 80 percent fewer active parameters than the top-ranked open-weight model.
The speech model processes plain-language prompts across 40 languages, including seven Indic languages, to generate transcripts, identify individual speakers, and translate audio into English. Quantized editions will deploy locally on RTX Spark, DGX Spark and Jetson AGX Thor devices using NeMo-Speech.cpp or vLLM. Liquid AI also released its LFM3 family of foundation models with day-zero RTX Spark support across text, vision, audio and decision tasks, led by a 1.7-billion-parameter base model.
NVIDIA added resource management controls inside the NVIDIA App under the System menu. The feature allows operators to allocate GPU resources between foreground applications and background software agents. Enabling the allocation tool requires hardware-accelerated GPU scheduling inside Windows Settings.
Gaming and modding tools
S-GAME released its action role-playing title Phantom Blade Zero on Steam and the Epic Games Store on Oct. 28 at 7 p.m. Pacific Time. The title incorporates ray tracing for bounced lighting and terrain shadows, alongside NVIDIA DLSS 4.5. The technology uses dynamic multi-frame generation to multiply frame rates up to 6x or adjust frame generation dynamically to maintain target performance levels.
The company also updated RTX Remix to version 1.6, adding modding support for Minecraft Java Edition 1.21.1 with path tracing and DLSS 5. Updates to Portal with RTX and the Half-Life 2 RTX demo introduced 3D-guided neural rendering, a performance mode for DLSS frame generation, and an updated ComfyUI workflow for creating physically based materials directly in the application.
NVIDIA manufacturing partners began selling standalone DGX Spark systems equipped with the GB10 Grace Blackwell Superchip and 64GB of unified memory. NVIDIA also launched Nemotron 3.5 Bolt E4B, a 4GB model designed to run local agents and voice interfaces on low-memory hardware, while Black Forest Labs released its 5.6-billion-parameter FLUX 3 Image Klein model for local image editing.
