Well there's confusion over issue vs decode, dispatch, and retirement; its both accurate to say A72 is 8-wide issue and also that the relevant number is 3-wide

Well there's confusion over issue vs decode, dispatch, and retirement; its both accurate to say A72 is 8-wide issue and also that the relevant number is 3-wide or maybe 5-wide if you believe ARM's numbers with uop fusion.
After all, the Cortex-A15 and A57 are also 8-wide issue. Incidentally all 3 are also 3-wide decode and dispatch, but A72 apparently decodes instructions to fewer uops.
