Athereos wireless cards (ath10k) have also used Xtensa. And the audio DSP in newer intel chipsets (e.g. Apollo Lake) is also Xtensa-based, but unfortunately quite locked down (signed firmware only). See https://thesofproject.github.io/latest/platforms/index.html Also ISTR that older Radeon graphics cards used Xtensa (e.g. in the Unified Video Decoder).
