Just an adjustment for accuracy.
The T234 is not an soc, it's a scalable Arch, and covers a range of soc configurations from The Orin AGX, at 12 cpu cores and 2048 Cuda Cores, to the Orin Nano at 4 CPU cores and 1024 Cuda cores.
They also removed the rtx series ray trace cores and have repurposed the die space within the sm to double sized tensor cores, and also have a Deep Learning Acceleratorfor even more ai training tensor acceleration power.
The t239 has 12 SM's, almost undoubtedly on a single 12sm GPC like ad102, to reduce complexity and power draw from a multi gpc arch, cause it's portable.
That means 1536 Cuda cores, 48 Tensor cores, 48 TMUs and 16 ROPs (these two are by far the weakest point of this system, although im not sure how much rops really matter for this system, particularly if its using dlss, but 48 tmus definitely hurts for texture rate) and 12 RT cores.
