Following a series of delays spanning several months, NVIDIA's compact AI supercomputer, the DGX Spark, has finally made its official debut. Priced at $3,999 (approximately starting from 30,000 yuan), this device packs a premium configuration. It is equipped with a GB10 Grace + Blackwell SuperChip processor. The CPU section of the processor comprises 10 Cortex-X925 cores and 10 Cortex-A725 cores, culminating in a total of 20 cores within an ARM architecture. The GPU leverages the Blackwell architecture, achieving FP4 performance of up to 1 PFLOPS. Moreover, it integrates fifth-generation Tensor cores and fourth-generation RT ray-tracing cores, culminating in overall performance on par with that of the RTX 5070.
