None of these leakers know anything, if they did we'd have some actual details from them, but every detail past the one single bit of info (T239 as a name) has turned out incorrect. Kopite got one thing right and just the naming and then proceeded to get 4 or 5 other things wrong, if you know everything about the chip how are you getting 5/6 things wrong about it?
The only reliable real info is from the two massive Nvidia leaks/ransomware attacks. Those show you the hardware specs and several other details straight from Nvidia. From that we know the CPU, we know the CUDA cores (1536), ray tracing functionality is in, DLSS is in, we know the graphics API (NVN2), we know several other things, that's direct from Nvidia.
