Hypothesis: that Qualcomm and that Macbook have higher memory bandwidth than your i9 system. This is dependent on your memory and your mainboard, not so much on the CPU itself. Perhaps Teams just uses way too much memory, and actually uses it all the time.

An i5-14500 has a comparable memory bandwidth as an i9-14900k

To me memory latency being whatever, 30% higher, ought not to explain the issue here, in part because that's a priori assuming all is memory-bandwidth-limited vs say network limited or CPU limited far as the bottleneck
What makes more sense to me is the software is "slow and clunky" that is maybe a global mutex, maybe poor multithreading sync making it effectively single threaded, with a sprinkling of particularly slow algorithms or syscalls that are realized as a frozen GUI, or as we call such cases, Microsoft standard
