The fact that this is the only chip that contains 8-cores on a single cluster suggests it's not simply product binning. |
Every chip in existence... Be it Ram, NAND, GPU, CPU or APU is binned.
Binning doesn't mean just deactivating parts of a chip, it can mean a change in voltages and clockrates.
Binning a Tegra chip may mean that you retain all the CPU cores, but loose GPU cores or disable a chunk of the memory controller... This is a balance Nintendo is going to have to chalk up... Because to much CPU grunt will take away from the graphics quality.

You're misinterpreting. There are no Tegra Orin modules with 8-cores per cluster outside of T239. The linux kernel even shows this. T234 (Jetson AGX) has 4 cores a cluster and 2-3 clusters depending on the module. The same is true for the Jetson Orin NX. This is confirmed in all documentation listed from Nvidia. Unless you are suggesting that the T234 is being binned (Which wouldn't make any sense), then this shows that there are customized components in comparison to ALL other Tegra Orin SOC's. Obviously not everything is "customized", but there does appear to be some customization to the chip, most likely for the purposes of shrinking the die.
Jetson Orin NX: "The CPU cluster is comprised of eight cores of ARM Cortex-A78AE Core processors organized as multiple quad-core clusters."
