Two things, first its an AMD processor so it would be AMD needing to move to 5nm for that specific processor, secondly would they do that for a games console that is considered middle aged?
I know the PS5 has an APU from AMD, which integrates both the CPU and GPU. I didn’t thought that on a tech forum I had to specify the APU is the one shrinking the node, but obviously when I said the PS5 is probably going 5nm I Was referring to their APU, which, as all we know, is manufactured by AMD.
Secondly, would they do that for a console APU? The answer is not only
yes, but they’ve been doing it since the release of the first model. If you’ve seen the insides of the 1000 series, the 1100 series, and the 1200 series, each one has a smaller -and lighter- heatsink, so yes, they will continue to improve PS5’s power efficiency.
If I recall correctly, the PS5 was released with the APU manufactured at 7nm and, if the rumors are accurate, by now they are using a process of “6nm”. I don’t formally know of any TSMC 6nm node, but that’s how specialized media refers to it, probably an enhanced 7nm node with higher efficiency.
And the 5nm process is going to be much more available on the foundries, now that many companies, such as Apple or Intel, or Nvidia in the near future, are moving to the 3nm process node. The PS5 Pro APU will almost surely be manufactured on a 5nm process, I don’t see the problem using it for the regular PS5 as well.
