Is the AMD Halo Station better than the NVIDIA DGX Station?

On paper it holds more memory: up to 576GB of HBM3e across four AMD Instinct MI350P accelerators plus up to 2TB of DDR5, about 2.6TB in total, against 252GB of HBM3e plus 496GB of LPDDR5X (748GB coherent) in the DGX Station. But as of November 10, 2026 the Halo Station is a prototype with no price and an AMD page that says 'Coming in 2027', while the DGX Station GB300 ships today through partners such as Dell, HP, ASUS, MSI, Gigabyte and Supermicro. If you need a machine this year, the DGX Station is the only one of the two you can buy.

How much does the AMD Threadripper Halo Station cost?

AMD has not announced a price. Its product page, read November 10, 2026, offers only a sign-up form and 'Coming in 2027'. Component costs for four Instinct accelerators, 2TB of DDR5 and a 96-core Threadripper PRO 9995WX point to a six-figure system, in the same range as a DGX Station.

Should I buy a DGX Spark instead of a DGX Station?

Yes, if your models fit in 128GB. The DGX Spark is a small GB10 desktop with 128GB of unified LPDDR5x and up to 1 petaFLOP of FP4 compute, priced in the single-digit thousands of dollars. The DGX Station adds about six times the memory and much higher bandwidth for six-figure money. Buy the Spark to prototype, fine-tune small models and run 70B-class models quantized; buy the Station to serve or fine-tune models with hundreds of billions of parameters at your desk.

Which local AI workstation runs a trillion-parameter model?

Both big machines claim it at low precision. NVIDIA says the DGX Station supports models up to 1 trillion parameters in its 748GB of coherent memory, and two Stations can be linked over ConnectX-8. AMD says the Halo Station's up to 2.6TB of combined memory keeps frontier-class models loaded. Expect usable but not datacenter-class speed.

Quick Answer

AMD Halo Station vs NVIDIA DGX Station vs DGX Spark (2026)

Published: November 10, 2026

The short answer

Buy the DGX Station if you need a deskside machine for very large models now, the DGX Spark if your models fit in 128GB, and wait for the AMD Halo Station only if you want the most memory and can wait until 2027. As of November 10, 2026:

NVIDIA DGX Station (GB300) — shipping through OEM partners; 748GB of coherent memory; NVIDIA states support for models up to 1 trillion parameters. Six-figure price.
NVIDIA DGX Spark (GB10) — 128GB unified memory in a small box; the realistic buy for most developers.
AMD Threadripper Halo Station — a prototype shown at IFA on September 4, 2026; up to 2.6TB of combined memory; “Coming in 2027”, no price.

AMD Threadripper Halo Station — most memory, not for sale yet

The Halo Station puts AMD’s datacenter Instinct accelerators in a tower. AMD’s headline is memory: up to 576GB of HBM3e plus up to 2TB of RDIMM, which AMD says is up to 3.4 times the total memory of a DGX Station. That matters for models whose weights simply do not fit in 748GB.

Two caveats. First, the 16TB/s is an aggregate across four separate accelerators, so a model has to be split across cards with tensor or pipeline parallelism; the DGX Station’s 7.1TB/s sits on one GPU. Second, it runs ROCm, not CUDA. vLLM and SGLang support ROCm, but some fine-tuning and custom-kernel tooling still assumes NVIDIA. Our Halo Station explainer covers the cost estimates.

Wait for it if you need more than 748GB in one box, prefer AMD’s stack, and can plan around a 2027 date that AMD has not pinned down.

NVIDIA DGX Station — the big machine you can buy today

The DGX Station pairs a Blackwell Ultra GPU with a 72-core Grace CPU over NVLink-C2C (900GB/s), so the GPU can treat all 748GB as one coherent pool. It supports MIG with seven instances, so a team can share one Station, and a ConnectX-8 SuperNIC (up to 800Gb/s) links two Stations to double model capacity. You can add one RTX PRO 6000 Blackwell card for graphics and simulation.

NVIDIA does not sell it directly: partners including ASUS, Dell, Gigabyte, HP, MSI and Supermicro set prices, and Tom’s Hardware reported a listing near $100,000. Plan for a dedicated 20A circuit: the system draws 1,600W.

Buy it if you fine-tune or serve 200B–1T-parameter models on sensitive data that cannot leave the building, and need CUDA.

NVIDIA DGX Spark — the realistic choice

The DGX Spark is a palm-sized GB10 system with 128GB of unified memory and up to 1 petaFLOP of FP4 compute. Its memory bandwidth is far lower than the Station’s, so large models run slowly, but it fits 70B-class models at 4-bit and handles LoRA fine-tuning of smaller ones. Two Sparks can be linked.

Its price has moved through 2026: $3,999 at launch, $4,699 from February 2026 for the 128GB Founders Edition, and partner listings reported in October and November 2026 put 128GB models near $6,950 and new 64GB models around $4,999 as memory prices rose. Check NVIDIA’s marketplace on the day you buy. For other desktop options see DGX Spark vs M5 Ultra vs RTX PRO 6000.

How to choose

Do your models fit in 128GB at the precision you need? Yes: DGX Spark. Use our VRAM guide to check.
Do you need a big machine in 2026? DGX Station; the Halo Station has no ship date.
More than 748GB in one box, or AMD-only shop? Wait for the Halo Station.
Not sure you need local hardware at all? A six-figure workstation buys a lot of cloud GPU time; compare in local workstation vs cloud GPU vs API.
