AMD launches Ryzen AI Halo workstation to challenge Nvidia’s DGX Spark

AMD is set to begin preorder of its Ryzen AI Halo developer platform in June 2026, a compact AI workstation that aims to rival Nvidia’s DGX Spark offering. The system pairs a 16‑core Zen 5‑based Ryzen AI Max+ 395 processor with 128 GB of unified memory and is priced at $3,999 [2].

Key takeaways

• Preorders start in June 2026, exclusive to Microcenter in the U.S. [2]
• The Halo uses a 16‑core Zen 5‑based Ryzen AI Max+ 395 APU with a 120 W TDP [2]
• It matches Nvidia’s DGX Spark on memory (128 GB) but offers lower FP16 compute (60 TFLOPs vs 1 petaFLOP) and slower networking (10 GbE vs up to 200 Gbps) [2]
• AMD’s broader AI momentum is reflected in a 6 % stock rise and record data‑center revenue in Q4 2025 [1]
• Nvidia still dominates the AI‑chip market with an estimated 81 % share, according to IDC [3]

Ryzen AI Halo specs and competitive positioning

The Ryzen AI Halo is built around AMD’s Ryzen AI Max+ 395, a 16‑core Zen 5‑based APU that consumes 120 W of power, compared with Nvidia’s GB10 chip in the DGX Spark which draws 140 W [2]. Both systems include a 240 W power supply to support motherboard, SSD, and cooling needs. Memory capacity is identical at 128 GB, and the Halo adds Wi‑Fi 7 and Bluetooth 5.4, though its Ethernet is limited to a single 10 GbE port, whereas Nvidia’s ConnectX NIC can reach 200 Gbps, enabling dual‑DGX Spark configurations for larger models [2]. In raw compute, Nvidia advertises up to 1 petaFLOP of FP4 performance, while AMD claims 60 TFLOPs of FP16, a substantial gap that may affect workloads requiring massive parallelism [2]. Storage on the Halo is currently limited to 2 TB, half of the DGX Spark’s 4 TB offering, and the price point of $3 999 is lower than Nvidia’s $4 700 for the comparable configuration [2].

AMD’s broader AI push and market context

AMD’s launch comes amid a broader rally in its AI‑related business. The company’s stock rose 6 % after announcing collaborations with the French government and a $60 million investment in autonomous‑vehicle startup Wayve, signaling growing confidence in its AI roadmap [1]. In the most recent quarter, AMD’s data‑center segment posted a record $5.38 billion in revenue, up 39 % year over year, underscoring strong demand for its EPYC and Ryzen CPUs in AI workloads [1]. Nevertheless, industry analysts note that Nvidia still commands roughly 81 % of the AI‑chip market, according to IDC, highlighting the challenge AMD faces in gaining market share [3].

Why it matters

The Ryzen AI Halo provides developers with a smaller, lower‑cost alternative to Nvidia’s DGX Spark, potentially expanding the ecosystem of AI‑ready hardware for startups and research groups that cannot afford larger, more expensive systems. However, the Halo’s lower compute performance, reduced networking bandwidth, and smaller storage capacity suggest it may be best suited for early‑stage development or smaller models rather than large‑scale training. As AMD continues to bolster its AI credentials through data‑center growth and strategic partnerships, the Halo will test whether the company can translate technical progress into meaningful market penetration against Nvidia’s entrenched dominance. The upcoming preorder period and the May 5 earnings release will offer further clues on AMD’s ability to sustain its AI momentum.
