You seem to have overlooked the Tegra X1, which powers 55+ million Nintendo Switches. Nvidia seems to already be invested in the ARM CPU market and doing relatively well. Their X2 powers the new Shield devices and who knows what else in the future.

Yes, that's a very tiny number compared to the billions of CPUs made by Intel, Apple, AMD, Qualcomm and Samsung, but the point is, they are already doing ARM CPU integration and have carved out a decent niche for themselves.

Also, the X1 uses an ancient A57. To enumerate, since then, we've had A72,A73, A74, A75, A76, A77, and the announced A78 and (interesting named) X1.

That's 7 major generations behind the curve.

Video game CPUs aren’t generally where the puck is going, sadly. Cell was interesting but other than that we’ve had a history of picking a semi-popular architecture and usually some old chip (Nintendo) or just a normal x86.

You are totally mistaken. Have you seen what the PS5 is doing with memory bandwidth? It's amazing. The entire PC industry is going to end up emulating their architecture.

Memory bandwidth (by using GDDR6 for shared RAM/VRAM) is impressive compared to PC but it's already done by PS4(GDDR5) and not special/difficult architecture like Cell. Just a difference comparing general hardware vs gaming hardware.

For normal PC workload, such bandwidth is not useful and GDDR increases latency.

IMO Interesting thing like HBM is happening in Server/HPC world.

I was talking about PS5's secondary storage being essentially as fast as RAM: 9GB/sec throughput with custom 12-channel controller to the new PCIe 4.0 SSD.

It's impressively fast and adopting it as standard equipment is great but similar SSD product should be available for PC soon. Not feel innovative like Cell.

Right, so you could say that "being available for PC soon" means that's "where the puck is going", correct? Which was my original point. The PS5 is a video game console, but isn't just commodity hardware, but is actually pushing the limits of computing in a way that the PC industry will soon adopt.

Also. It might be much longer than "soon". Though Sony is targeting the next gen SSD specs (unlike Microsoft), there will need to be a new generation of motherboards and CPU upgrades before PCs will be able to come close to the PS5 bandwidth, even with the same exact next gen SSD.
