NVIDIA DGX Spark and DGX Station: personal AI Supercomputers
(Image and Video source: Nvidia )
In GTC March 2025, NVIDIA announced two personal AI Supercomputers: DGX Spark and DGX Station, both of them are purpose-built with Grace Blackwell architecture. And, Dell says its AI PC powered by Nvidia is arriving early Summer 2025.
Let us take a look at the specifications of them:
-
It puts a GB10 superchip on the desk, theoretical 1000 AI TOPS at FP4 precisions support, and, 128 GB LPDDR5x system memory is designed to mobile devices for high performance and low power consumption.

-
It is built with the NVIDIA GB300 desktop superchip, 784GB coherent memory space accelerates large-scale training and inferencing workloads at our desktop. NVLink-C2C extends NVLink technology to a chip-to-chip interconnect between the GPU and CPU, with up to 800 Gb/s, ConnectX-8 SuperNIC optimized for hyperscale workloads.

- NVFP4 : The NVFP4 is one of the new FP4 formats supported by NVIDIA Blackwell GPU, quantized with TensorRT Model Optimizer, it demonstrates good accuracy compared with other 4-bit alternatives, e.g. INT4, more importantly, it can score 99.8% of FP8 on MMLU general intelligence benchmark. (discussion in Benchmark results compared to orig fp8 / int4 quants etc?)
