Nvidia Launches 64GB DGX Spark at $4,999 as RAM Shortage Pushes 128GB Model to $6,950

Nvidia introduced a 64GB variant of its DGX Spark local-AI desktop at $4,999, launching October 23 through Acer, ASUS, Dell, Gigabyte, HP and MSI with no Nvidia-branded unit. The 128GB model simultaneously jumped from $4,699 to $6,950, nearly 75% above its original $3,999 price, with Nvidia blaming tight DRAM supply expected to persist through 2028. The cheaper box keeps the GB10 Grace Blackwell superchip and 273 GB/s bandwidth but caps local inference at models up to 100B parameters.
