An aging X-series Core i9-10980XE — which patch of AI work does it still own today?

  One patch survives: cheap, large-memory, many-core data work. Four DDR4 channels give it twice the memory lanes of today's dual-channel desktops, and with 256GB populated it can stage a tens-of-billions-parameter quantized model for slow offline inference, bulk embeddings or corpus cleaning. 18 cores/36 threads with AVX-512 keep the parallelism honest.

  Sensible as a budget secondary box when the platform is already in your hands. Building a new machine around it is a losing trade — four DDR4 lanes still trail modern dual-channel DDR5 in raw bandwidth, and 4.6GHz single-core pace has slipped behind today's software stacks. It also demands a separate display card, so run the full ledger before committing.
