Either I am having a really thick day or the wording of the WccfTech article is quite confusing, and I'm not tallking only about the technical terms.

"Digging through the leaked files, several users were able to spot that the NVN2 API is designed to work with NVIDIA's Ampere GPU architecture and will feature support for both Ray Tracing & the aforementioned DLSS (2.2) technology. Now what's more interesting is that there are references to the T234/T239 SOCs which according to Kopite7kimi were going to power the new Nintendo Switch 2 console."

Ok, fine from now.

"These SOCs will be a custom Orin design and will have a codename starting with a 'D'. The two possible codenames for the SOC are either Dane or Drake though some believe that these SOCs and the codenames were only specific to the Switch Pro which has been canceled in favor of a truly next-gen Switch console."

Fine as well, but they're hinting that all that comes next may mean nothing as plans could have changed, classic leak/rumor disclaimer.

"The T234 SOC is suggested to feature 2048 Ampere GPU CUDA Cores and 12x ARM Cortex-A78AE (Hercules) 64-bit cores..."

No problems here even for a non-tech savy as myself, but

"... The T239 which will be custom-designed based on this is suggested to offer slightly different specifications. The specific GPU that the SOC will be using seems to be the Ampere GA10F and it is rumored to feature the chip is said (or rumored) to feature the same SEC8N rate as ORIN, 1024 FP32 rate, or half of Orin. The SOC will also likely carry AV1 support."

Is there something missing there, or the wording is wrong? What chip are they talking about, the GA10F or is it another?.

Also, if someone could, please, explain what SEC8N is, I'd appreciate it.

By the way, out of curiosity I checked TechPowerUp's GPU database to see if there's any Ampere GPU available with 2048 cores, just to have an idea of what that T234 could be capable of, and there's currently no GPU available, but there will be three with that core count later this year: the GeForce MX570, RTX 2050 Mobile and RTX 3050 Mobile (the difference between the later two appear to be the memory bus width, one half the other).

So yeah, I doubt that's poweful enough to give a proper RT experience, much, much less if the Switch's SoC ends having half the cores.

I wouldn't look too deep into wccftech since their writers aren't very good but rather just pay attention to the sources.

Basically what they are referring to are the guesses that Kopite made when it comes to the Switch 2's SoC:

T239 would be like the product version in the family. So the original product is called Orin T234 and Nvidia will take that as a base template and create a custom version for Nintendo and call it Orin T239.

GA10F is where it will be placed in Nvidia's GA product stack. So like a GA102 is 3090/3080 and etc. So GA10F is for Orin. They are talking about the same chip, it's just worded weirdly.

SEC8N I believe means Samsung 8nm. SEC I believe is the name of Samsung's semi-conductor division.
