The PSREF processor table uses a dash for the AMD Ryzen 5 PRO 7540U NPU field; this record does not convert that source notation into an unsupported conclusion.

These are PSREF platform options, not the NPU installed in an individual Model / MTM. Overall platform performance is distinct from NPU-only performance.
