DEVKIT core differences between e200Z4 PNs?

From: https://www.nxp.com/docs/en/supporting-information/DWF13_AMF_AUT_T1056.pdf

Slide 9: Core Usage vs. MPC57xx Automotive MCU Family:

Between the 5744P and 5748G there are 3 different cores listed as "e200z4":

e200z4204n3

e200z4251n3

e200z424

And multiple z4 cores listed across all of the devices. Are there any architectural differences between the part numbers? Is it just an internal reference as to how they are on die?

And an aside question, what is the origin of the 'codenames' for the processors. Some are mountains. Racerunner is a lizard, calypso is Greek and panther is a cat.

One note to checker core (in your question e200z424), its number is subtracted by 1 and it is equal core as main one (e200z425) but does not have internal memories IMEM/DMEM/ICache/DCache. It is only used for lockstep.
