I mean can you imagine the uproar it would cause if Apple did that?
We're trying to understand why did the existing M1 Mini perform worse in some of those tests than the M1 Air did, while there is no known reason for it. Some speculate that they inexplicitly sell subpar/low freq chips, which would mean that they were selling an official 7-core, an official 8-core and a faster but otherwise non-advertised version of 8-core. And on top of that, the latter would be installed in Mac Air that has the worst (passive) cooling solution from all current M1 offerings...
That doesn't make sense on any level and is just something Apple could not do and successfully hide from everyone, especially that they already have an explicit binning process.
