A GB300 desktop and a small DGX Spark cluster do different jobs. The GB300 has 252 GB of memory at 7.1 TB/s and serves large models to a whole team, split into up to seven slices. A Spark has 128 GB at 273 GB/s: enough to fine-tune a 70-billion-parameter model, too slow to serve one to many people. Put serving on the GB300 and development, fine-tuning and tests on the Sparks. The graph, rules and search software around the models runs on CPUs and needs its own tier. Prices and export rules for the UAE are at the end, checked on 16 October 2026.
