M7 Ultra may feature native FP8, potentially boosting GLM 5.3-flash performance

A user speculates that a future M7 Ultra chip, inheriting M6's native FP8 support, could significantly enhance GLM 5.3-flash (Ox Alpha) efficiency. GLM 5.3-flash is designed for FP8 E4M3 matmul (likely on Ascend 950), while M5 and below rely on software emulation (Int8 to FP16 conversion). The user plans to benchmark the performance delta between native and software FP8 on M6.
