According to its Hot Chips 2020 presentation, AMD originally planned on having Renoir top out at 6 cores. However, TSMC's efficient 7nm process allowed AMD engineers to design an 8-core CPU within limited silicon and thermal constraints.

Meh, who cares. Intel was probably only planning on having one core in their CPUs, because they seem to really want you to make the one core vs one core test results the headline in all of your AMD vs Intel articles.
please don't gaslight for the sake of publishing some articles... How can they put odd number of cores in CCX if that was the real intention... This doesn't make any sense >:(
