Just to add something, GPU core counts are all counted differently and meaningless across architectures. An Apple GPU core is 128 ALUs, say an Intel one is 8. 

Seeing what they did with the 8C M1, the prospect of a 128 core Apple GPU is amazingly tantalizing, that's 16,384 unified shaders.

Tantalizing and absurd because you will be starving most of your shaders sitting their doing nothing and that's not how GPUs work. Apple is investing in their specialty processing to be the heavy lifter--the Neural Engine, ML Engine, Audio/Video Decode/Encode process most of the system's requests already. 

Seeing what they do with a meager for a GPU 70GB/s already, I would think they will think out the bottlenecks. But certainly the design has to make sure it's well fed to scale that high. 

What do you mean, that's not how GPUs work? The GPUs rumored are 128C, and so far Apple's allocation is 128 ALUs/core. Also for a 2022 product, that's about double the ALUs in a 3080, I don't know what you think is absurd about it.

I'm giddy, I can't wait for the event and results. 

 Gurman says the first Mac parts will be 12C, 8 big/4 little, so I think this 8C part won't be it, unless they are only counting big cores. Or else A14X for the 13" Air and/or 12", this 12C Firestorm/Icestorm part for Pro? A14T will be that, perhaps. 

I'm going to assume this was mistakenly referring to the GPU update in 2020 as a 2020 model unless proven wrong. With the November ARM event looming, I think it's going to be all ARM refreshes from here, and the 16" probably in 2021, the Intel iMac probably being the last new Intel model. 

It probably shouldn't, but it somewhat impresses me that it reads like the judge has a firm handle on what's happening here. 

Maybe I'm just used to congress people ask limp questions to tech CEOs. 


Pretty happy with the results, I was worried for Unreal Engine particularly on Apple Silicon, but Fortnite was their own folly.
