While AMD’s Strix Halo devices offered 128GB unified memory for local AI long before NVIDIA’s entry, NVIDIA defined the desktop local-AI category with the one-liter DGX Spark. Launched alongside the Ryzen AI Max PRO 400 Series in May 2026, the $3,999 AMD Ryzen AI Halo serves as AMD’s direct counterpart to the DGX Spark, with pre-orders opening in June via Micro Center and in-store availability starting July 10. Matching the Spark’s compact footprint and 128GB unified memory, the Halo features key design differences that redefine its use cases.
Core Specifications & Hardware Design
Powered by the 16-core/32-thread Zen 5 Ryzen AI Max+ 395 APU, the Halo integrates Radeon 8060S graphics (40 RDNA 3.5 CUs) and an XDNA 2 NPU delivering 50 TOPS, with a combined system AI throughput of up to 126 TOPS. Its 128GB LPDDR5x-8000 memory provides 256GB/s bandwidth, supporting local inference of up to 200B-parameter models, and runs on a 120W single USB-C power input.
The 150×150×45.4mm, under-1.2kg aluminum chassis adopts a high-airflow ventilation design with a status indicator ring. Rear I/O includes three USB-C data ports, one USB-C power port, HDMI 2.1b, 10GbE Ethernet and a Kensington lock slot. Internally, it uses dual-fan cooling and a standard M.2 2280 SSD slot (max 8TB upgradeable), unlike the Spark’s rare 2242 drive. AMD pre-sets maximum Variable Graphics Memory across Windows 11 and its custom Linux developer image, eliminating manual tuning for large AI models. A key tradeoff is the absence of high-speed fabric, limiting multi-node clustering versus the Spark.
Key Differentiators vs. NVIDIA DGX Spark
The Halo’s biggest advantage is dual Windows/Linux OS support, addressing the top user complaint about the Linux-only DGX Spark. It offers broader aftermarket storage compatibility and user-friendly visual status lighting, while matching the Spark’s core large-model local inference capability at a lower price. The Halo retails for $3,999 with 2TB storage, while the updated DGX Spark costs ~$4,700; third-party Grace Blackwell systems sit at a comparable $4,000 baseline.
Performance Benchmarks
Windows Workstation & AI Performance
Tested against identical-spec HP Z2 Mini G1a and ZBook Ultra G1a systems, the Halo delivers top-tier comprehensive performance. It scores 37,316 in Cinebench R23 multi-core and 184.2 GIPS in 7-Zip compression/decompression, leading all rivals. In UL Procyon AI tests, it achieves industry-leading scores: 1,192 for Phi text generation and 937 for Stable Diffusion 1.5 image generation, with drastically reduced first-token latency. It also leads in SPECworkstation 4 financial, media and product design workloads, with consistent advantages in Geekbench 6 single/multi-core and GPU OpenCL performance.
Linux CPU & Storage Performance
On Linux Phoronix benchmarks, the Halo outperforms the DGX Spark in CPU-centric tasks: 11% faster 7-Zip compression, 38% faster decompression and 14% quicker LLVM compilation. For storage, the Halo’s Gen5 SSD is locked to Gen4 speeds, creating a bandwidth gap. It excels at low-queue-depth latency for random I/O but falls behind the Spark in high-load sequential throughput, saturated random write IOPS and sustained high-concurrency storage performance.
LLM Inference (vLLM)
The Spark dominates high-concurrency LLM serving, with 2–4x higher throughput in most scenarios, peaking at 8.8x faster performance in prefill-heavy 120B-parameter model tasks. The Halo remains competitive in decode-heavy workloads (within 10–12% of the Spark) and lightweight 8B-model inference, making it viable for daily local AI development.
Conclusion
The Ryzen AI Halo is a well-balanced compact x86 AI workstation rather than a direct Spark competitor. It outperforms all tested Ryzen AI Max+ 395 devices in Windows professional and AI workloads and beats the DGX Spark in Linux CPU tasks. Its core strengths are dual-OS support, flexible upgradability, user-friendly tuning and mainstream compatibility at a competitive price.
The DGX Spark remains superior for high-throughput LLM serving and multi-node clustering. Meanwhile, the Halo is ideal for developers needing Windows-Linux dual-environment AI development and unified professional workloads. AMD also plans a 2026 Q3 upgrade to 192GB unified memory, extending the platform’s support for larger AI models.
