Best laptop CPU for single thread processes - eviltoast

Hi, my laptop got fried because of getting caught in the rain :(

I got a gaming laptop for work a few years ago, because appearantly the CPU AMD Ryzen 9 6900HX was about the best thing to be found for updating some ridiculously complicated excel power query circusses at work, according to the internet back then (i think I found that info on pc master race on reddit before the reddit-api-fall), and finding those CPU’s in business laptops was rather difficult at the time. They were right, this CPU handled the queries like a walk in the park.

Is the AMD Ryzen 9 6900H* still a very good CPU for this kind of thing, or should I put in a lot more time investigating again, is there better cost-efficiency available now in other CPU?

Sorry if this is not a right place for this question. I’m usually not really a hardware guy. Just need a CPU that handles this Excel shit as fast as possible, preferably without locking up the entire machine and without being as noisy as an F16 getting ready for lift off. On “regular” work laptops with i5 or i7, these files can take literally over an hour to update.
