DGX Spark adds a $4,999 64GB tier

The archive’s PAIR analysis concluded that its router distributes whole requests but does not pool model memory. NVIDIA now says two partner-built 64GB DGX Spark units can pool 128GB through Sync Cluster Assistant; each starts at $4,999 on October 23, and the company reports up to 1.7× performance on its Qwen 3.8 27B test. That leaves the PAIR call intact while adding a separate memory-pooling path, at an announced two-unit floor of $9,998 (2 × $4,999). Builders who are memory-bound should evaluate this cluster path against their target model and workload; NVIDIA’s result is one vendor test, not a general scaling guarantee.
