Sony Principal Graphics Engineer confirms PS5 has custom architecture that is based on RDNA2. (Update: Read OP)

So let's look at it logically for a second. You are building a soc which has to be capable of running next gen VR games as well as regular flat screen gaming. You have the chance to include features such as ML and VRS. ML could help push VR games to a much higher frame rate without affecting fidelity by using a form of MLAA. Why wouldn't you include this in your chipset, knowing the potential gains meet your objectives?. I appreciate that it's always a balance, but come on.

As far as VRS is concerned, it's a feature that less than 10%? of your customers are going to be able to use, and that's being generous. Need to save space on your die? Yeah that's getting cut.

Tbf I'm not confirming VRS has been cut, I just don't consider it would be a priority if your stripping out features anyway to make room for IO improvements.

... what? Do your mean VRR (variable refresh rate)? VRS is something that video games do in terms of rendering regardless of display, it would happen for everybody, what are you talking about 10%?

Not to mention how neither of these things take for space

Well, I did say “if this is true”.

I've been saying those things too. And I think it is quite possible that even Lockhart will have better performance than PS5, if all those things are true. ML based up sampling itself would give a 120% - 200% performance boost based on DLSS 2.0 figures.

Sure there is.

Different architecture results in different performance.

GPU A with 10 tflop can have better performance in games compared to GPU B with 10 tflop.

So - 1 tflop of RDNA 2 is better (or worse but better is more likely) in real life performance than 1 tflop of RDNA 1.

That's how I understood it.

I'll say what I said with the SSD before the Sony conference. If this gives a big advantage to Microsoft, we better see it on Thursday.

Sure, people here will debate it for days, but if the games are similar it makes no difference.
They are launch window games. Of course the difference wont be massive... Yet

You will need to wait for a few years until the "real" next gen games which are being made now are launched

this thread has really taken off lol.

We've already had the conspiracy theorists. The "then Xbox is rdna 1 too lolz" guy. The one who discredits the engineer. The guys in denial and the ones justifying it 🤣🤣.

These threads are why neogaf is getting all these clicks 👏👏👏👏 lol.

Reminds me of when it became clear that PS5 was 10TF so people started saying SX MUST be only 10 TF and 6x2 wasn’t 12 and Phil was lying

It must be because Sony is broke and can't afford RDNA2.....

They probably can't afford to make good games anymore either...

I heard PS5 is held together with chewing gum and doublesided sticky-tape too!

Looks like Xbox has next gen ON LOCK!!!

Streaming is the future and console sales don't matter.... but also they do!

Can't wait for Microsoft to charge extra to listen to the music that used to come with games.... bright future ahead of us guys! So Bright... CELEBRATE!!!!

Praise be to Timdog, who died for our sins!
Dont you know only rdna2 games count as next gen?
Sony has none by the looks of it. All games including horizon 2 were running on xsx and will be down ported to the much weaker ps5 and sold as fake next gen with fake 4k and sub 20 fps.

Only xsx can produce true next gen games.
Hellblade 2 and the medium already shit on everything ps5 has to offer.

Only xbox brand is capable to run far cry 6 at true 4k.
Ps5 already way behind.

Now we know why.

Sony mark cerny was lying as always.

Did i mention sony censorship? Total deal breaker.

Oh and the ssd hahaha like that will do anything.

Facts are facts.

Sony is shit. Xbox is king .

Good luck buying an outdated console at 500 when the xsx will be 400 and lockhart max 299 but all rumors point at 199


Also you can say good bye to your back log disc collection or any free upgrade of cross gen games if you are poor enough to buy the digital only version and for the same price.

What a rip off.

Have you seen scorn?? Only possible on xsx.

Ps5 could never play it at such resolution

This is a big deal if true. Here is a very rough hypothetical breakdown.

12 TFLOPS
+ 25% ML upscale efficiency improvement
+ 25% IPC improvement (RDNA2 is supposedly 50% more than RDNA1, but I split that in half)
+ 25% VRS efficiency improvement

= 23.4TF or 130% performance difference over PS5

Sony just shot themselves in the foot.

I don't know how much the rest of you know about Japanese culture (I'm an expert), but honor and shame are huge parts of it. It's not like it is in America where you can become successful by being an asshole. If you screw someone over in Japan, you bring shame to yourself, and the only way to get rid of that shame is repentance.

What this means is the japanese public, after hearing about this, is not going to want to purchase a PS5, nor will they purchase any of Sony's games. This is HUGE. You can laugh all you want, but Sony has alienated an entire market with this move.

Sony, publicly apologize and redesign the PS5 as RDNA2 or you can kiss your business goodbye.
what bullshit. Nowhere did they say they had full RDNA2. They didn't screw over their customer base at all. Their silence was telling.

Yes sorry VRR, it's late, and I'm struggling to sleep. Maybe 'space' wasn't the right word to use, but you see my point, cutting out ML makes no sense if it was an option.
 

Care to make an actual argument?

I have no idea if this is true, I’m just pointing out that these features and architectural differences actually make a big difference when you add it up. RDNA1 and RDNA2 are both big leaps for AMD, and ML upscale and VRS are equally huge efficiency improvements. There’s been a very interesting leap in GPU hardware lately and if this rumor is true then PS5 missed out on some of these.

Imagine being such a huge fanboy for Xbox (correct me if I'm wrong on this), that your brain conjures up such excited theories. If such a difference existed, there would be nothing stopping developers from pointing out such huge performance gaps months ago.

Why does any thought that doesn’t agree with you necessarily come from a “huge fanboy”. My post was a literal “what if” based on reasonable numbers (I was honestly somewhat conservative).

If the ps5 isn't RDNA2 and XBOX is full RDNA2 the gap isn't that small anymore.

that depends on what parts of the PS5 is RDNA1... but if it is an in-between I would bet what's missing is the performance gains of the PC RDNA2 cards.

it will be interesting to see if the Series X is full on PC equivalent RDNA2 in teems of performance, or if it also is between the two.

Yea, but they'll be on the PC for Max settings. :messenger_beaming:
Even if this was to happen the majority of people will still play on PS5 and there would be a year wait for PC guys :) I personally don't have a problem with the games going to PC but I'm not going to wait to play my favorite games

Those were conservative numbers? What are you even basing those numbers on? Neither of these consoles are out, nor is an actual full RDNA2 GPU. Hell, we still don't know exactly what's in these chips just yet. It's absurd to just go, well one is 1.5 and the other is clearly 2.0, so math. Considering the long development cycles of these machines, both are probably hybrids, and by cutting the fat they gain a little.

We know PS5 will have the best RDNA 2 features as Sony would have chosen them. And the gap will be small especially with Sony likely having an even better checkerboard implementation for the PS5
