However, with a memory bandwidth of 273 GB per second, the DGX Spark does not match the capabilities of some competitors like the M3 Ultra series from Apple, which boasts superior bandwidth at 819 GB per second. This brings to light a crucial consideration: while LLMs require substantial memory for efficiency, the combination of bandwidth and memory size is vital. Nvidia's current memory limit of 32 GB on its high-end RTX boards poses challenges when handling more complex models that exceed this threshold.
