To explain briefly, T239 is the model number of the chip that Nintendo and Nvidia have been working on for upcoming hardware. This was leaked by a reliable Nvidia leaker last year (who got a lot about the 30 and 40 series right before announcement). This chip has now been 100% confirmed twice-over, though I'm sure that some of the slower among us (you know who you are) will still say it's fake out of cope from desperately wanting Nintendo to go back to AMD.
So, what does this reveal about the chip? It's an 8-core cluster, which means it's using the Cortex A78C architecture. For reference, that is 6 generations ahead of the current Switch chip. It's a massive jump, but of course it can run Switch code natively. That means full compatibility and no "double-dipping" as another certain idiot might call it. And this is most likely just a revision rather than a new generation! Sounds crazy, but the reveal of DLSS 3.0 today shows that a 2026 or so Switch 2 with the Ada architecture can be pretty impressive even if the jump on paper isn't huge.
Oh, and to preempt what I know someone will point out: Yes, I am aware that the Tegra X1 in the Switch also has 8 cores but 4 are disabled, so you may argue that Nintendo would do the same here. The difference this time is that the Switch's 8 cores are are in two clusters with different architectures, and it's not possible to run both clusters at the same time. Enabling the 4 small cores would not have had any impact on performance. IT would have saved battery life outside of gaming maybe, but nothing else. That's why those cores were disabled on most X1-based devices, including the flagship Nvidia Shield TV. Since this is one cluster in one architecture, this issue is moot and it's far less likely that cores would be disabled. Even if they are, it won't be more than 2.
Sadly, that's all we can get from this. We know the GPU architecture is Ampere (which is probably more believable to people now since it's "outdated"). Sadly, we can't determine the number of GPU cores from this.
Switch revisions happen every 2 years, so we pretty much know one is coming next year.
