"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:

Yes, where desktops differ is not so much the chips but rather the cooling capability. You have the space to have proper air flow and water cooling etc. So that do give quite a bit of performance.
