A first hands-on look at NVIDIA's DGX Spark, sent directly by NVIDIA. The unit measures just 15 × 15 × 5.05 cm and weighs 1.2 kg. Inside:
- NVIDIA GB10 Grace Blackwell Superchip
- 128 GB unified memory shared between CPU and GPU
- Up to 1 petaflop theoretical AI compute at FP4 with sparsity
A replier suggests a 70B QLoRA fine-tune on the creator's own posts as a killer demo for the machine.
