Apparently this just happened:
LeakGeekerwan got a Switch 2 motherboard early and did a full die shot analysis of T239 with help from Kurnal

"Good tl;dr of the video from Resetera:
207mm² v.s. 118mm²
It's also larger than the RTX 3050 Ti (mobile) GPU, Apple M2, Ryzen 7840H (Z1 extreme) and Qualcomm's X elite.
Tape out year of the SoC was on 2021 as annotated on the die. They also looked at the RTX 3050 GPU die, which had a tape out year of 2020.
T239 brief summary.
8 Core A78C cores, with 4MB L3 Cache and 256kb L2 cache on each die
The die area of the A78C is the same as the 8nm T234 orin, indicating the same process node.
The C and AE suffix doesn't bear much meaning on the core design itself, but rather the ARM classification indicating Compute and Automotive and how the cores operating
6 TPC, 2SM/TPC, 1536 CUDA Cores
Ampere design, although it's layout seems odd as the TPC's are separated
The design of the GPU seems more alike to Ada Lovelace
in terms of area of the TPC, the T239 is 22% smaller than the orin T234
There are some differences in the chip design itself, it's not exactly 8nm and some aspects are closer to Samsung's 10nm process node fabrication.
They highlight the previously "leaked" clocked speeds and like DF mention that its closest equivalent is the RTX 2050, although heavily downclocked.
Like DF they also do a simulation of Switch 2 performance with the RTX 2050 downclocked as a proxy.
The docked performance is aligned to the GTX 1050 Ti in docked mode and GTX 750 ti in handheld mode in Synthetic tests Steel Nomad Light
It's far from the Xbox Series S and the closest mobile equivalent are Apple's A18 Pro, M1 in docked mode, and the Steam Deck is a bit better in handheld mode
They test Cyberpunk 2077, Black Myth Wukong, Monster hunter Wild, KCD2
They also took a T234 board (Orin) and tested CPU performance through synthetics (geekbench 6)
Downclocking it to 1.1 GHz and 1 GHz, its single core performance is twice as much as the PS4 and 3x the Switch, closest laptop equivalent is the i7-4700HQ.
Closest mobile equivalent in multithreaded performance is the A12 in the iPhone, which btw has more than 2x the single threaded performance compared to the "Switch 2"
They also used a downclocked i7-10700KF to approximate Switch 2's CPU performance"
