When I first heard of the DGX Spark, I wasn't a fan. Despite its 128 GB of memory, the 273 GB/s memory bandwidth seemed too low. For reference, an RTX 5090 has about 6.5x the bandwidth (1,792 GB/s), despite only having 32 GB of VRAM. When it launched, speculative decoding wasn't widely adopted, and most small models were not quite as capable. As the AI industry progresses and grows, intelligence is being compressed into smaller and smaller sizes, which lets these little boxes be used to their fu
