MLID leaked about Magnus: could be SoC for upcoming PS6. PS5 Pro's SoC is having 279 mm2 @ N4P, Magnus comes with total 408 mm2 @ 3nm. Pretty big die but kind of expected for next generation console.

Could be xbox

3 big cores and 8 dense ones, looks weird.

 

[marees]

So the man said he used chat gpt to conclude it is for Sony

It is chat gpt vs @Kepler_L2 now

3 big cores and 8 dense ones, looks weird.

Probably 10C/20T in the console, with one extra Zen6c for binning

Or they simply had some space left, to put another core on the Die.

But 144m2 for the SoC part seems to be rather big. Are there additional memory PHY on the SoC Die? Or does the GPU Die really have a 384bit SI instead of 192bit?

So 2 + 8 or 3+7? The latter looks even more weird (sorry if something is not a power of 2 it looks weird )

Still I would expect for 12 cores a mix of 8 + 4 dense with 4 reserved for the OS/background stuff, and 8 perf fully available for games. Now the devs will need to make core aware thread placement.

It looks like the GPU die is just Shader Engines + GPU Front-end, Memory controllers + MALL? And SoC is everything else (CPU, Display, Media, PCIe, NPU?)

Does it make sense to put the NPU far from the GPU cores and caches? That way they can't use the NPU to offload FSR4 or other ML upscalers in games, for example.

They aren't going to run upscalers on the NPU.

Heterogeneous cores in a console. Running an operating system with a Microsoft-written scheduler.
That's a recipe for success.

 

[marees]

The speculation is that performance will be between 5080 and 4090/5080 super

Assuming this releases next november what would be the street price of the 5080 super at that point in time ? I don't see the console selling below that

As a sop to gamers, Microsoft could partner with AMD for an RDNA 5 based z3 extreme ? for handhelds by various 3rd party partners

Not sure if microsoft will also partner with AMD for a medusa halo like APU
