Cerny announces new PS5 Details

[SteveGrabowski0]

I wish we knew if the cpu will have SMT or not.

i just remembered the chinese console thing, and it made me wonder if the PS5 would use the GPU's VRAM for system RAM o_o

 

GDDR6 would be interesting, HBM2 would be insane (both ways ._.)

PS4 already uses GDDR5 as system memory so it wouldn't be news and it seems like they'll repeat it with GDDR6 for PS5.

Yeah which is how they get overall console prices way down, but "bandwidth higher than whats available on PC" is still expensive considering how much we have on a 3.0x16 slot (which most GPU's cannot even fully saturate). Assuming they're just referencing that PCI-E 4.0 isnt available on PC, then it's only a matter of time

you say "most"... what GPU's can saturate 3.0x16?

Titan V or maybe the dual vega card for data centers (what stadia is using) would be possibly getting close, Crossfire runs over PCIE so crossfire setups possibly too. SLI can run over pcie but doesnt, they could go back to that assuming SLI still exists for awhile

It probably won't, since it doesn't add much value to games while making the system less deterministic.

I don't see why not since every console this generation uses unified memory.

The RTX 2080 Ti seems to show noticeable signs of performance degradation on PCIe 3.0 x8.

(I'ts not full 100% 3.0x16 use but its getting measurable)

If the backwards compatibility thing is for 100% of PS4 games, then sign me right the fuck up

So is the 1660 Ti a good option now or should I wait for Navy?

[DragonTamer1]

I'm too lazy to look it up, is this the same PR guy that said the PS5 would do 4K at 240FPS or something like that?

 

I'm only mildly surprised that they said it would have Ray Tracing as the upcoming Xbone is supposed to have it as well. Same with the SSD, I still want to know if that's something the user would be able to replace and upgrade or if it is mounted right to the board.

 

The Ray tracing will probably be a different technology than what Nvidia uses. I know there is more than one type but I don't know the specifics of each one.

Mark Cerny is designated as the system architect, additionally Lisa Su retweeted the wired article, seems mostly legit

It was some business analyst.

I wouldn't write off SMT for gaming since it added a lot to the i3 back around the time of Haswell when the i3-4130 would crush a nearly 5 GHz Pentium G3258 in gaming despite having the same number of physical cores. To a lesser extend the quadcore i7/XeonE3 have ridden this console generation out really well while I read a lot of complaints about the quadcore i5. Of course this current gen is a different situation where the XB1/PS4 use octacores with low IPC and terrible clockspeeds so games were absolutely forced to run over 8 cores. And the situation could be very different next gen now that AMD has a really good cpu architecture. I'm hoping for no SMT in the next gen consoles so my Xeon E3-1231v3 might have a fighting chance through the first half of the gen. If not though gotta say Ryzen 7 is looking like a pretty compelling buy.

If you're at 2 cores, then any potential drawbacks to using SMT over not would likely be overshadowed by the benefits it could provide. But if you're at 8 full cores already in today's environment, adding SMT doesn't make as much sense.

That's not true. The operating systems of these consoles tie tasks to cores, not all 8 are available to games.

[albertmamama]

Wlid guess: PS4 pro will be rebranded as PS5 "lite".

Absolutely this. If I recall, both the Xbox One and Playstation 4 reserved 2 cores for the operating system and features, then distributed the remaining. One core would continue running the very OS and the second would run other features like constant game recording, like ShadowPlay for Xbox, so basically, games only really used 6 cores at most.

 

I think some games were allowed to disable features to allow use of the 7th core, but I'm not sure if I'm remembering that correctly, I just remember this tidbit of information for some reason.

Sony unlocked the 7th core. 

[Doobeedoo]

A huge step up in performance this will be. The CPU alone will be numerous times faster. Zen2 along with much higher clock speed may finally allow games to actually be 60fps this time around, so that better be a thing. Navi is also a big improvement architecture wise, so actual 4K that is proper and not reconstruct crap should be much more easily achievable.

As for SSD that will be a massive change. By then and bulk buy prices will be quite cheap.

I'm conCerned about thermal situation since One X has a vapor chamber just to keep up 4K. Water cooled console?

No, because that'll increase the cost of the console, which is the last thing they'd want to do.

 

The XBox One X has what's basically a slightly bigger, somewhat downclocked RX 580 in it, which is rated for 180W. The closest and latest thing on NVIDIA's side to that power wise is an RTX 2070. Given Navi is supposed to be a 7nm chip and compete with Turing, you could argue the performance of an RTX 2080 could be within that power envelope.

 More like 90-99% of games.
Because some games already crap out if they run in "boost mode" on the PS4 PRO.

The 2013 Tomb Raider comes to mind here.

 

But that's a Fuckup on the Game Developer side, wich might prevent upwards compatibility of the Software.

Besides that, there shouldn't be anything in the way of PS4 Games on PS5.

How much of a difference will it be when going from jaguar to zen cpu in terms of performance? can anyone guess?

Not sure what kinda guess you want here, a vague answer might be 3x+. Depends on the core count/threads, clocks, zen1/2, etc.

 

i would think atleast 4x+ though.

The Athlon 5350 uses the Jaguar core. So it's likely up to 4 times faster.

Keep in mind that the 5360 only has a single channel (64bit) Memory interface...

It would be really interesting to compare that with other Chips with similar frequencies and also Single Channel Memory...
