DigitalFoundry confirmed this through Gotham Knights performance analysis The PS5 reserves 1.5 cores of its CPU for the operating system and applications. We’ve known for a long time that the Xbox Series X also reserves its CPU core and 2.5GB of unified memory for the operating system and core applications, but we still didn’t have clarity on this information for Sony’s console.

The exact amount of unified memory that the PS5 will reserve for the operating system and its main applications has yet to be revealed, but the latest information we’ve seen points to between 2 GB and 2.5 GB. It’s a perfectly believable figure, since the PS4 reserved 2.5 GB and thus had 5.5 GB free for games.

What does this mean and why is it important? Well, it’s very simple, it assumes that the developers have available for the games, 6.5-core processor running at a maximum frequency of 3.5 GHz (can go below this frequency) and also only have a break between 13.5 GB and 14 GB of unified memory, which is used as RAM and VRAM interchangeably.

In addition to all of the above, we must also add that the CPU used by the PS5 is based on the Zen 2, but uses a custom design that trim both FPU and L3 cache. For comparison purposes, the Ryzen 5 3600 processor also uses the Zen 2 architecture, but as we can see in the attached table, it has four times more L3 cacheit runs at a stable 4 GHz in all its cores, and its FPU design is clearly better as well.

If we put all this into context, the conclusion we can draw is very clear, Ryzen 5 3600 is much better than PS5 CPUand as I told you then, we don’t need an 8-core Ryzen 7 3700X to have a Sony console-level PC, no matter how much others insist on pointing the wrong way.

In their review of Batman Arkham Knights, DigitalFoundry used a computer with a configuration of a Ryzen 5 3600 and GeForce RXT 2060 Superand this one achieved results much better than PS5 in said game. It also reaffirms what I’ve been telling you practically ever since the first details about said console started leaking, that there was pointless “hype” and that the “next generation” was rather a disappointment in terms of performance.

If you want more information on this topic, I invite you to read this article dedicated to the five things you don’t need to build a PS5 and Xbox Series X-level PC. As for the analysis of Gotham Knights, the game is pure chaos and a clear example of how things should not be done. It suffers from a major CPU bottleneck, caused by very poor optimization, and shader loading has been implemented so poorly that the game suffers from constant stuttering. I’ll leave you with the video so you can see it in more detail.
