Looks like the numbers I was looking at were for the high-power configuration, and differed a little between sources, nontheless the low-power configuration, which has a significantly lower TDP (23W) than the M3 Pro (~30W), while having the same core count, is still very close to M3 Pro performance even if M3 Pro is a bit higher.
