It is so "telling" when the single-core performance isn't listed. As others have said, many of us are not in the Media-Biz and don't care about "graphics"; we want "crank power".
By not listing the M5 single-core stats, it raises the question of whether it is actually lower than the M4.
Maybe someday an AI "pre-compiler" will look at the code and automatically compile it to utilize multi-cores. For now, the code I write, loops and calculations, wants the fastest single-core it can get.
