"Desktop chip" hasn't been a meaningful variable for single-thread performance in more than a decade. A single core can't use more than a given amount of power or it would melt and laptops have that much in their power budget.
Where a desktop's TDP is actually useful is for multi-thread performance, and naturally the multi-thread chart is topped by Threadrippers.
Moreover, Geekbench is rubbish in general. For example, it has Threadripper 9980X with a <50% higher multi-thread score than Ryzen 9 9950X even though it has twice the memory bandwidth and four times as many of the same cores and you have to look pretty hard to find a real multi-threaded workload where it's not significantly more than twice as fast:
