RTFA:

“ Users will notice that the 16-core processor is more expensive ($3521) than the 24 core processor ($2900) here. This was the same in the previous generation, however in that case the 16-core had the higher TDP. For this launch, both the 16-core F and 24-core F have the same TDP, so the only reason I can think of for AMD to have a higher price on the 16-core processor is that it only has 2 cores per chiplet active, rather than three? Perhaps it is easier to bin a processor with an even number of cores active”
