No, because there's no definition of a "GPU core". Vendors just pick a random layer of their GPU and call it a core. Whether or not it makes any sense as being called a "core" or being comparable in any way isn't a goal of anyone's.

Really they aren't even comparable across a single vendor (the capabilities of a single "SP" on an Nvidia GPU has drastically shifted over the years - and not always in the "more capable" direction)

At best you can roughly compare GPUs from the same generation from the same family (eg, M1 Pro vs. M1 Max). But that's about it, and even that can be deceptive (most commonly in desktop GPUs where other differences can drastically alter scaling across differing "core" counts)
