I think it's telling that they are delaying the microcode patch until after all the reviewers publish their Zen5 reviews and the comparisons of those chips against current Raptorlake performance.
Why even publish a comparison? Raptor Lake processors aren't a functioning product to benchmark against.
Because if publishers don't publish then they don't make money.
Because the benchmarks will still exist on the sites after the microcode is released and a lot of the sites won't bother to go back and update them with the accurate performance level.
