FP8/FP4 Quantization Delivers Only ~1.5x and 2x Real Speedups, Far Below Theoretical Gains

The author argues that FP8 and FP4 quantization do not provide the theoretical 2x and 4x speedups over FP16/FP8 — realistic gains are closer to 1.5x and 2x. Also comments that 100 days is a somewhat ridiculous timeline while 30 days is overly optimistic.
