NVIDIA GB10 (DGX Spark) Price: $6,950 List Price, Specs and Buy vs Rent
GB10 is the Grace Blackwell chip inside NVIDIA's DGX Spark, a small desktop box with 128GB of memory shared between a 20-core Arm CPU and a Blackwell GPU. People search for it to find out what the Spark costs and whether it beats renting a data center GPU for local model work. The answer depends mostly on memory bandwidth: 273 GB/s is enough to load very large models, but it caps how fast they generate tokens.
TL;DR: GB10 price
- Price: The NVIDIA GB10 Grace Blackwell (DGX Spark) launched at $3,999 on Oct 15, 2025 and lists at $6,950 as of Oct 3, 2026.
- Specs: GB10: 128GB LPDDR5x unified memory, 273 GB/s, up to 1 PFLOP FP4 (sparse).
- Rent: Spheron does not rent the GB10; the closest card it rents is the RTX PRO 6000 (96GB) from $1.53/hr spot, live as of Oct 20, 2026.
- Break-even: $6,950 buys about 4,540 hours of RTX PRO 6000 rental at that rate, before power and the host machine.

Buy the GB10 or rent a cloud GPU
Buy a DGX Spark if you want a quiet desktop machine that can hold a 70B-class model in memory, you work with sensitive data that cannot leave your desk, or you are building against NVIDIA's Arm and CUDA stack before deploying to Grace Blackwell servers.
Rent instead if token throughput matters. The Spark's 273 GB/s is a fraction of what an HBM data center GPU moves, so a rented H200 or RTX PRO 6000 serves the same model much faster, and you stop paying the moment the job ends.
96GB of GDDR7 on one card, the closest single-GPU match for models sized to the Spark's 128GB pool.

GB10 price FAQ
What the GB10 costs, what it runs, and when renting beats buying.
The DGX Spark Founders Edition with GB10 and 128GB of memory launched at $3,999 on Oct 15, 2025. NVIDIA raised its MSRP to $4,699 in February 2026, citing memory supply constraints, and the 128GB model lists at about $6,950 as of October 2026, alongside a new 64GB model at $4,999. Partner systems from Dell, ASUS, HP and others are priced separately, so check the seller for the current figure.
GB10 is the chip and DGX Spark is NVIDIA's system built around it. GB10 pairs a Blackwell GPU with a 20-core Arm CPU over a shared pool of 128GB LPDDR5x. Partner desktops from Dell, ASUS, HP, Lenovo and others use the same GB10 chip under their own names.
Yes. A 70B model quantized to 4-bit needs roughly 35-40GB for weights, which fits comfortably in 128GB of unified memory with room for KV cache. Generation speed is limited by the 273 GB/s memory bandwidth, so a dense 70B model at 4-bit generates in the single digits of tokens per second.
At $6,950, buying the GB10 costs the same as about 4,540 hours of renting the RTX PRO 6000 on Spheron, the closest card it rents at $1.53/hr spot (live as of Oct 20, 2026). At eight hours a day that is about 1.6 years of use, before electricity, the host machine and resale value. If the card would be busy for less than that, renting costs less; if it would run longer, buying usually wins.
