Amount of CPU core or CPU core speed?

As I am about to have decide between the following CPU: AMD Ryzen 9 5950X (clock rate 3400 MHz, Turbo Mode 4900Mhz) (cost 150$ more ) or AMD Ryzen™ 9 3950X (clock rate 3500Mhz, Turbo Mode 4700Mhz)
I am unsure since they have a minor performance difference. According to google the performance of each thread of the 5950X is around 30% higher than the other modell. Each model have 16 cores.

Does it make any difference in terms of chia plotting? Or this is performance difference only noticable when gaming?

It probably has a directly proportional effect on plot speed.

Overall you want to favor more cores vs. faster cores, but this is speed alone.

How much are you planning to plot?
