Nvidia DGX Spark 64GB: Price, Specs and How It Compares

Nvidia’s 64GB DGX Spark is scheduled to arrive on October 23, 2026, with a starting price of $4,999. It uses the same GB10 Grace Blackwell platform as the original Spark, but has half the unified memory—and the original 128GB model’s price has risen well above its $3,999 launch price.593

Price and availability

The 64GB configuration will be sold through Acer, ASUS, Dell, Gigabyte, HP and MSI. Nvidia says it will be available exclusively through these manufacturer partners, rather than as an Nvidia-branded Founders Edition.5

DGX Spark configuration	Price and availability	Memory and stated local model capacity
64GB	Starts at $4,999; scheduled for October 23, 2026	64GB unified memory; up to 100 billion parameters, according to Nvidia
128GB	$6,950 in reports published October 2, 2026	128GB unified memory; reports cite support for models up to about 200 billion parameters

The new entry price is $1,000 more than the original 128GB Spark’s $3,999 launch price. The 128GB model is now reported at $6,950—about 74% above that launch price.931

What the 64GB model includes

The 64GB system retains the GB10 Grace Blackwell Superchip, ConnectX-7 networking and Nvidia’s DGX software and AI stack. Reports list 2TB of storage, half the original model’s storage, alongside the reduced memory capacity.5315

Nvidia says a single 64GB Spark can run models with up to 100 billion parameters locally. The 128GB model is associated with a roughly 200-billion-parameter capacity.131 These are vendor-stated maximums: whether a particular model fits and how well it runs depends on the model and workload.13

How it compares with AMD’s alternative

Some mini PCs built around AMD’s Ryzen AI Max+ 395 offer 128GB of unified memory for roughly $3,400–$4,000, based on price reports from September 2026.1820 That can make them a cheaper way to get a 128GB local-AI system than buying the current 128GB DGX Spark at its reported $6,950 price.

It is not a direct hardware-for-hardware match. The AMD systems use the Ryzen AI Max+ 395, while the Spark is built around Nvidia’s GB10 chip and DGX software stack.195 The cited price range also reflects reported AMD configurations, not a single fixed price for every model.1820

What the memory crunch means for buyers

Reporting links the 128GB Spark’s price increases to memory-supply constraints: the model launched at $3,999, rose to $4,699 in February 2026, and was later reported at $6,950.93 The new 64GB version costs less than that current reported price, but offers half the memory and storage—and its $4,999 starting price is still above the original 128GB model’s launch price.39

The available reports do not give a confirmed timeline for when memory supply will ease or Spark prices might change. Buyers should treat the listed prices and availability as snapshots, not a forecast.
