| numberwang said: We don't know the shader count of the Switch 2 or really anything about its internal soc structure. The leaked image does not confirm anything that was speculated before with that T239. Switch 2 having 3x the "shading units/cores" to a Steam Deck is implausible on a comparable die size / transistor count without sacrificing something else on the die. Look at it this way: Switch 1 had a die 118 mm² (TSMC 20nm) with 307MHz in handheld mode with 0.157 TFlops. A 5x increase to 0.8 Tflops on Switch 2 handheld through a bigger die, a better fabrication node and higher clocks is reasonable. |
Yes we do know that the T239 is a 12SM Ampere chip with 1536 cores. This is one of the things we know more than anything else, and have known for years now. It's not speculation. It is hard data from the Nvidia hack. It has been corroborated dozens of times over the last three years.
For example, Eurogamer/Digital Foundry wrote an article about it in 2023.

The hack also suggests that T239 has 1536 CUDA cores, 75 percent of the cores of the much larger T234. |
It is much more of a known than the manufacturing process.
Are you going to be in denial about this until the chip releases in March or April and it is a side-comment in some breakdown of the die because everyone else has already accepted this fact for years now, and it isn't really interesting anymore?
Also, the die-size range we are observing currently was predicted years ago too.
