You might be surprised to learn that dell "hpc engineers" (or maybe HPE?) have attempted to sell me hardware using that exact logic to compare servers.
Given a highly-parallelizable numerics job, and all other things being equal, a 20 core 2.0Ghz machine will run the job in the same time as a 40 core 1.0Ghz machine.
...though usually we'd just give it in FLOPS - though FLOPS doesn't describe non-float operation performance.
Probably just a sales/marketing person who learned a new technical word and wants to sound knowledgable to the customer but it back-fires.
