The memory shortage has reached Nvidia’s desktop AI box. Per HotHardware, 64GB versions of the GB10-based DGX Spark are due October 23 through partners, while the 128GB model has gone up sharply.
The numbers
- 64GB model: from $4,999 (the Dell Pro Max with GB10 is listed there); MSI, ASUS, Gigabyte and Acer are also partners.
- 128GB model: $6,995 per HotHardware, up from a $4,699 recommended price and a $3,999 launch price. Other outlets report $6,950, and Nvidia’s own site may show stale pricing. Verify at purchase.
- Specs: GB10 chip, 64GB LPDDR5x on a 256-bit bus, ConnectX-7 with dual QSFP ports up to 200Gbps.
- Why: rising DRAM and NAND prices; Nvidia responded by halving the memory to offer a cheaper entry point.
What you give up
Models around 80B parameters and up are a poor fit at 64GB, and dense mid-sized models run slowly on this bandwidth, though mixture-of-experts models run well. Nvidia says 64GB covers most agent tasks such as summarization and computer use.
Where to be skeptical
- The “cheaper” system still costs $1,000 more than the original 128GB launch price. This is a price increase wearing a new SKU.
- Pricing is from press reports and partner listings; we did not verify through a reseller, and these are US dollar figures. Canadian pricing is not confirmed.
- AMD Ryzen AI Max+ 395 mini PCs are cheaper today, but their makers are expected to raise prices as well.
Takeaway
For teams prototyping local agents on small or MoE models, 64GB is probably enough. For anyone planning to run large dense models locally, the 128GB price jump makes cloud GPU rental a more serious comparison than it was a year ago.
