NVIDIA opens RTX Spark laptop preorders

NVIDIA opened RTX Spark laptop preorders on October 7, advertising up to 128GB of unified memory and availability on October 16, according to its Windows-event announcement. Compact desktops are due in November; NVIDIA positions those systems for continuously running local agents. The specifications and claimed model capacity are vendor statements, not evidence of accepted-task throughput or complete deployment cost. Teams evaluating the hardware should carry forward our Ghost Core analysis of local-agent hardware economics and benchmark their own workload before treating memory capacity as a performance guarantee.
