NEON optimizations can have pretty large effect (up to ~4x), just like SSE. The benchmarks with the largest differences are suspect, especially SGEMM. Also don't underestimate how much RPi4 throttles under multicore load. Even the cheapest $1 heatsink will make a big difference. In general I agree, though. It'll still be in the same ballpark.
