PS5 Pro Features 2 GB Of Extra DDR5 RAM For OS & Non-Gaming Apps, GPU & PSU Specs Revealed

Sony Interactive Entertainment's upcoming mid-gen console, the PS5 Pro, features 2 GB of extra DDR5 RAM for OS and non-gaming applications.

2gig of extra ram. That's interesting.
I wonder why this wasn't revealed earlier

[DarXyde]

Your guess is as good as mine in wondering why it wasn't mentioned earlier. My thinking is that it simply wasn't the time to say so in a 9-minute video. Even then, Sony controls the length of their own presentations, so we're back to the question of "why", really.

I can't say I'm surprised though since PS4 Pro did the same thing: use a slower RAM handle other tasks and free up resources to get more out of the other upgrades. A 16.7TF upgrade is nothing to sneeze at either. That's greater than if a PS5 magically absorbed the GPU power of a PS4 and PS4 Pro.

But we know it's greater than that in practice and TFLOPs are largely theoretical. The utility of PSSR really frees up the GPU to do some interesting things, though I suspect it's mostly going to be used for enhanced ray tracing.

It would have been cool to see some CPU side upgrades, but fair enough. This thing is still a proper monster.

Didn't cerny say that they had freed up some ram in the vid? Honest question because I can't remember lol

[darthv72]

Another way of putting it is combining PS5 + Xbox One X.

They did the same thing with the PS4 Pro, they gave it 1GB of DDR3 to gain back 512MB of the GDDR6 for the graphics. And yes Cerny did say that its got like another 1.67GB of GDDR6X for graphics for the PS5 Pro. And the DDR memory was for the OS, although I felt like it barely mad the OS any faster.

[CrimsonIdol]

The freed up a bit of the expensive GPU RAM with cheap system RAM for use with the OS. no longer unified memory but that's a good thing, not like the OS needs blisteringly fast memory. They did mention that they'd freed up just enough more memory for the increase in GPU performance (or maybe that was in the leaks, but I remember hearing that)

[VenomUK]

Is that memory used to run the PSSR and PS4 upscaling?

[IRetrouk]

It'll be for the os

[ABizzel1]

It’s for OS, the VRAM that was freed up from removing the OS from the GDDR6 is what is likely being used for PSSR and giving devs probably another +1GB to work with.

[badz149]

and it's DDR5 not DDR4 which is the version supported by the Zen2 CPU it's using. what the heck is going on here?

[Popsicle]

That is a great question because this is good information to have. IMO Sony has not done a very good job of marketing this console and is evidenced by how skimpy their marketing campaign has been. That said, I think this is likely strategic since it is considerably cheaper to have gaming publications and social media platforms do the bulk of the marketing for them.

I am no tech expert, but I suspect adding 2gigs of ram to the OS should offer some more headroom to provide advanced ray tracing, resolution upscaling, etc. This is good news. I will see for myself on Nov. 7th!

[OpenGL]

No idea but the PS4 Pro did a similar thing with DDR3. (1GB I think?)

[Grilla]

They added the 1gb so they could run the ui in 4k on the ps4 pro.

[plmkoh]

Makes it like the PS5 dev kit.

[ironmonkey]

Hmmm well that's good

[gold_drake]

this is so odd

sony has not revealed any of that stuff, why?

[Loktai]

It’s for sharing applications to easily deal with capture or streaming of media at higher resolution- and as scratch space for applications handling AI up scaling tasks in enhanced photo modes (up to devs to implement) : source: my friends wife works at the firm in MA who designed the chip that does that in the ps4 and ps5(and one reason it was known super early the ps5 would play ps4 games- because the chip Sony ordered was required to be fully backwards compatible with the ps4 IC which does that task)

[Lightning77]

Wait didn't Cerny say he's using next iteration of AMD's GPU? RDNA 4 or something equivalent to that? The leaked spec sheet shows RDNA though it doesn't show which version.

So it's either this leak is vague or fake or Cerny is greatly over exaggerated the specs here.

[ABizzel1]

The DDR5 is system RAM being used to free up more for he 16GB of GDDR6 the system used.

The base PS5 gave developers I believe access to 13GB of the 16GB of VRAM, and the other 3GB was used for system purposes. The PS5 Pro basically now has the additional 2GB of DDR5 for OS and other system purposes, and basically gives developers access to up to 15GB of VRAM for games.

The DDR5 was just a significantly cheaper way to give the system more VRAM, in comparison to making the PS5 Pro go from 16GB GDDR6 up to 20GB of GDDR6.

[Chocoburger]

Good to hear, but they would've received less flak over the price if they told us all of the hardware upgrades at once.

Excited for mine to arrive next week!

[BehindTheRows]

No, they wouldn't have. Y'all would have still moaned and complained.
