Bandwidth basis
MLU270-S4 inference card: 16 GB GDDR5 class, ~102.4 GB/s class bandwidth - republished spec. Treat bandwidth as low-confidence; Cambricon's public spec coverage is thin and largely aggregator-only.

notes
TRAP. Cambricon MLU270-S4 surplus cards surface on eBay at ~$315-320 (Oct-2026) with tempting paper specs, but the Neuware/CNRT software stack has NO llama.cpp, NO vLLM, NO GGUF route - you would be writing against a closed vendor SDK. Physically easy (PCIe, ~70-75 W single-slot) but the software is a dead end for open-weight LLM inference. Recorded status=contested and confidence=0.4 because spec coverage is aggregator-only and thin; the PRICE is real, the SOFTWARE PATH is the trap. Sibling MLU370 (cambricon-mlu370) has its own record.
