Introduction
The NVIDIA DGX Spark is the latest innovation in AI computing, designed to bring supercomputer-level performance into a compact desktop-friendly form. Officially launched on March 18, 2025, the DGX Spark was previously known as Project DIGITS. It is powered by the NVIDIA GB10 Grace Blackwell Superchip, featuring advanced Blackwell architecture GPUs, a 20-core Arm-based CPU, and 5th-generation Tensor Cores, delivering 1,000 AI TOPS of performance. This makes it a powerful tool for AI researchers, data scientists, and developers who need high-speed model training, fine-tuning, and inference capabilities in a local environment.
The DGX Spark comes with 128GB LPDDR5x unified memory, high-bandwidth interconnects, and self-encrypting NVMe storage (up to 4TB). Additionally, it integrates seamlessly with NVIDIA’s AI software stack and provides an optimized workflow for developing and deploying large language models (LLMs), deep learning algorithms, and AI-driven applications. With a competitive price of $3,999.00 (~RM17,741), the DGX Spark aims to deliver exceptional AI computing power at an accessible price point.
Technical Specifications and Performance
The DGX Spark is built around NVIDIA’s Grace Blackwell architecture, offering a unique combination of CPU and GPU processing power. It features a 20-core Arm CPU, composed of 10 high-performance Cortex-X925 cores and 10 efficient Cortex-A725 cores. This ensures a balanced workload distribution for both general computing tasks and AI-specific applications.
The Blackwell GPU integrated into DGX Spark brings the latest advancements in CUDA cores, 5th-generation Tensor Cores, and 4th-generation RT Cores. With a memory bandwidth of 273 GB/s, the system can efficiently handle high-resolution spatial data, deep neural networks, and generative AI models. The NVIDIA NVLink-C2C interconnect enhances CPU-GPU coherence, enabling a 5x improvement over PCIe 5.0 bandwidth, which significantly accelerates data-intensive AI training and inference tasks.
Other key specifications include WiFi 7, Bluetooth 5.3, USB 4.0 (40Gbps), and 10GbE Ethernet for high-speed connectivity. The system operates at 170W power consumption, making it efficient compared to larger AI workstations while still delivering supercomputer-class AI capabilities in a 1.2 kg, 150 × 150 × 50.5 mm form factor.
Comparison: DGX Spark vs. Apple Mac Studio (M4 Max)
For professionals considering an alternative AI workstation, Apple’s Mac Studio (M4 Max) is often a point of comparison. The M4 Max configuration features a 16-core CPU, 40-core GPU, and 16-core Neural Engine, with 128GB unified memory and a 4TB SSD, priced at RM18,476.50 (~$4,165). While both systems offer high memory capacity and storage, the DGX Spark is vastly superior for AI/ML workloads, thanks to its 1,000 AI TOPS of dedicated AI compute and NVIDIA Tensor Cores, which significantly outperform Apple’s Neural Engine.
The Mac Studio excels in creative applications, video editing, and general computing, benefiting from Apple’s ProRes acceleration and optimized Metal API for graphics processing. However, for GeoAI, deep learning, and large-scale AI model training, DGX Spark is the better choice due to its dedicated AI processing power, CUDA acceleration, and seamless integration with cloud AI platforms like DGX Cloud.

How DGX Spark Benefits GeoAI, LLMs, and AI/ML Applications
The NVIDIA DGX Spark is a game-changer for GeoAI, large language models (LLMs), and AI/ML applications, enabling researchers and developers to process large-scale geospatial, textual, and multimodal datasets with unprecedented efficiency.
For GeoAI, the Blackwell GPU with CUDA acceleration allows for high-speed geospatial data analysis, including satellite image classification, spatial-temporal modeling, and real-time object detection for autonomous navigation. The 128GB unified memory is particularly beneficial for handling large geospatial datasets without bottlenecks, while the 10GbE Ethernet and WiFi 7 provide fast access to remote data sources.
In LLMs and AI/ML, the 1,000 AI TOPS performance enables fine-tuning, inference, and deployment of models with up to 200 billion parameters locally. This makes it ideal for natural language processing (NLP), AI-driven content generation, and chatbot development. The NVLink-C2C architecture ensures seamless CPU-GPU data sharing, minimizing latency for high-performance AI workflows.
Additionally, the DGX Spark provides a direct pathway to cloud deployment via DGX Cloud and other data center solutions, allowing researchers to scale their local AI models into enterprise or distributed environments without major code modifications.
The NVIDIA DGX Spark stands out as a highly efficient, AI-optimized desktop supercomputer that delivers exceptional performance for AI/ML researchers, data scientists, and GeoAI professionals. With its compact design, cutting-edge Blackwell GPU, and full-stack AI software integration, it offers unparalleled value for those needing high-speed AI computation in a local environment.
Compared to traditional AI workstations or alternatives like Apple’s Mac Studio (M4 Max), DGX Spark is the superior choice for AI-driven applications, especially in areas like GeoAI, LLM training, and deep learning. While Mac Studio remains a strong contender for creative professionals, it lacks the dedicated AI acceleration and high-performance tensor computing capabilities that make DGX Spark a true AI powerhouse.
The choice between the NVIDIA DGX Spark and the ASUS Ascent GX10 depends on the user’s specific requirements. If storage capacity is a priority, the DGX Spark (4TB) is the clear winner, as it provides four times the storage of the GX10 for an additional $1,000. This makes it the better option for users working with large AI datasets, high-resolution geospatial data, or complex AI/ML models that require significant storage space. Additionally, the metallic chassis and NVIDIA’s branding may appeal to professionals looking for a premium, high-end AI workstation.
On the other hand, the ASUS Ascent GX10 offers the same AI processing power at a lower cost, making it a cost-effective alternative for users who do not need large internal storage and are willing to use external drives or cloud-based storage solutions. The white plastic design also provides a different aesthetic, which may appeal to users looking for a more modern or minimalistic look.
Final Verdict
Both the NVIDIA DGX Spark and ASUS Ascent GX10 are excellent AI supercomputers, but their differences in storage, price, and build quality make them suited for different user needs. For those who require high internal storage and a premium build, the DGX Spark (4TB) at $3,999 is a better long-term investment. However, for those who want to save $1,000 while maintaining the same AI processing performance, the ASUS Ascent GX10 (1TB) at $2,999 remains a compelling alternative.
