NVIDIA and CUDA
DGX Spark
A compact 128 GB Linux system for NVIDIA-native work, local AI development and selected larger-model jobs.
DGX Spark uses the GB10 Grace Blackwell superchip and NVIDIA's DGX OS. NVIDIA rates it at up to one petaFLOP of FP4 AI compute with sparsity, and says a single unit can work with models up to 200 billion parameters.
That headline is not the whole buying decision. Its 273 GB/s memory bandwidth is lower than a high-end Mac Studio, so a Spark can hold a large model without necessarily feeling faster when it writes. CUDA compatibility and NVIDIA tooling are the reasons to choose it.
