NVIDIA's $4,999 desktop supercomputer gets a cluster upgrade
NVIDIA just revealed the 64GB DGX Spark for $4,999, launching October 23 through manufacturer partners like Dell and HP. Powered by the GB10 Grace Blackwell chip, a single unit runs 100-billion-parameter models locally, and two units can cluster directly via cable to pool 128GB memory with up to 1.7x performance. Why it matters: It gives developers a powerful, private sandbox for agent workloads without racking up cloud bills.
