> Nvidia's Grace CPU are competitive against AMD's CPUs

I don't think PS/Xbox are using AMDs 64+ core server chips like Milan etc.

> I assume you have good sources to back up the claim that Neoverse V2/V3/V4

These are data center CPUs designed for very different purposes. Neoverse is only used in chips that target very specific, highly parallelized workloads. The point is having a very high number 64-128+ of relatively very slow but power efficient cores and extremely high bandwidth.

e.g Grace has comparable single thread performance to Ryzen 7 3700X (a 5 year old chip). Sure MT performance is 10x better but how does that matter for gaming workloads?

I assume you could boost the frequency and build a SoC with several times less core than all recent Neoverse chips (if ARM let's you). Nobody has done that or publically considered doing it. I can't prove that it's impossible but can you provide any specific arguments why do you think that you be a practical approach?

> substantially more powerful than something like Cortex-X4.

Of course it's just rumors but Nvidia seems to be going with ARM A78C which is a tier below X4. Which is not particularly surprising since Nintendo would rather spend money on other components / target a lower price point. As we've agreed the GPU is the important part here the CPU will probably be comparable to an off the shelf SoC you can get from Qualcomm or even MediaTek.

That might change in the future but I don't see any evidence that Nvidia is somehow particularly good at building CPUs or is close to being in the same tier as AMD, Intel, Qualcomm (maybe even Ampere depending if they finally deliver what they have been promising in the near future).

Same applies to Grace, the whole selling point is integration with their datacenter GPUs. For CPU workloads it provides pretty atrocious price/performance and it would make little sense to buy it for that.
