It’s more complicated than that (you’re assuming that the bigger CPU is optimized for the same workload) but it’s also irrelevant to the topic at hand: they’re seeing this NPU within a factor of 2-4 of the CPU, but if it performed half as well as Qualcomm claims it would be an order of magnitude faster. The story here isn’t another round of the specialized versus general debate but that they fell so far short of their marketing claims.
