PlayStation 5 System Architecture Deep Dive |OT| Secret Agent Cerny
Posted in the NX Gamer thread, but relates to the PS5 architecture. In the end it’s just another opinion Youtube video. But I think it helps validate why Sony focused so much on the I/O and bandwidth. Someone should make a thread about this (I can’t create threads for some reason). The video...

This channel Coreteks focuses on PC gaming/GPU industry and doesn't have any sort of "allegiance" to Microsoft or Sony. He argues that Sony's focus on I/O and bandwidth has won the console architecture design "war" and that he sees this as the biggest differentiator in the upcoming console generation. He quotes Nvidia's position on this, which is that communication is much more expensive than a compute operation.
"Arithmetic is free (low precession), communication is prohibitively expensive (in energy cost)" - Nvidia Slide
"Accessing even a small array costs way more than doing an operation." - William Dally Nvidia, Chief Scientist
It's a bit long at 45 minutes but I highly suggest watching the whole thing.
More tidbits:
- he believes there will be PS5 games not possible on PC (due to Sony's high speed architecture and having to design to lowest common denominator in PC's)
- he thinks the PS5 will be more expensive to manufacture because of its I/O design and 12-channel custom controller
- he believes both consoles will perform about the same as RTX 2080 GPU + R7 3700X CPU, highlights PS5's potential in particular
- Nvidia will have a hard time marketing a $700 GPU when consoles are able to perform that well
- Super fast asset streaming is a game changer and will be PS5's advantage over both PC and XSX. Argues that things like Sony's Spider-Man demo will not be possible on XSX because MS didn't focus on high performance I/O
- AMD's RDNA reveal and demo at Computex last year may have hinted at the possibilities of a high bandwidth architecture (a la PS5). Lisa Su quoted Mark Cerny and how Cerny wants to revolutionize gaming in the next decade
- Project Awakening by CyGames shown back in 2018 may have actually been the first footage of a PS5. Also points out that the developer is aiming for a highly seamless open-world. Coreteks thinks this could be the game that Cerny alluded was using ray-tracing at a high level.
