NVIDIA is adding a lower-priced version of its desktop AI computer. On Oct. 2 the company said a DGX Spark with 64GB of memory goes on sale Friday, Oct. 23, starting at $4,999. It will be sold only by hardware partners Acer, ASUS, Dell, Gigabyte, HP and MSI, not by NVIDIA itself.
NVIDIA says the new version keeps the same GB10 Grace Blackwell chip, DGX OS and NVIDIA AI software as the 128GB model, and its spec sheet, which covers both memory sizes, lists one memory bandwidth figure, 273 GB/s. NVIDIA says it runs models of up to 100 billion parameters on the device. ASUS, which sells its version as the Ascent GX10, says that comfortably covers today's popular agent models of 30 to 35 billion parameters.
For comparison, NVIDIA's online store lists its own 128GB DGX Spark, with 4TB of storage, at $6,950, shown as out of stock. The same page lists 128GB partner machines from $5,999, an ASUS Ascent GX10 with 1TB of storage. It lists the first 64GB models from Acer, ASUS and Dell as coming soon, with 1TB to 4TB of storage.
Buyers who outgrow one box can add a second. NVIDIA says two 64GB units joined by one cable pool 128GB of memory and can run models of up to 200 billion parameters, and its NVIDIA Sync app sets up the link. In NVIDIA's own test on the Qwen 3.8 27B model, two linked 64GB units delivered up to 1.7 times the performance of a single system. A model launcher for the app is due at the end of the month, the company says.
The trade-off is memory. ASUS points buyers who work with larger or fine-tuned models to the 128GB version. The 1.7 times figure also comes from a single NVIDIA test on one model, and NVIDIA did not say what it measured.
Still unknown: what each partner will charge above the $4,999 starting price, the full storage options from Gigabyte, HP and MSI, and how the machines perform in independent tests.
