Thank god we will probably find out more tomorrow when AMD finally talks about RDNA2 and probably who they created it with.

And soon Sony will confirm . Not point for you to lie that it’s not . Just like u lied and said the quote never existed lol

He's lied about saying the port on the XSX looked like CFexpress day 1, which I never seen him mention. He lied about RDNA being capped at 40CU and have nothing to prove it. I'm sure he lied about his age being 60+ and I'm sure he's not a dev.

Playstation: Zen 2, 7nm (not 7nm+, which would be RDNA2), Radeon Navi (which can mean RDNA or RDNA2)



"next gen Radeon technology"


Xbox:



"next generation Radeon RDNA gaming graphics architecure"

The two are not the same. It's RDNA for PS5 and RDNA2 for Xbox.

That would be something! One way or another... one group is gonna get smacked down in the fun of this all!

nah. One group just says that he did NOT confirm that PS5 is based on RDNA 2.0.

which is 100% true. He never DIRECTLY said that PS5 has RDNA 2.0.

Of course, one could „interpret“ it this way. Or one could say „he implied it“.
But saying that he 100% said that PS5 is based on RDNA 2.0 is factually untrue.
the quote just doesn’t say that, no need to deny that, it’s right there.

it seems many here can't understand the concept that by saying something is not the case, that doesn't mean you are saying the opposite must be the case instead.

Person A "We have many blue windows, I also like red windows, and we have a window on our roof"

Person B "SO THE WINDOW ON YOUR ROOF IS BLUE?"

Person C "he never said that, could be red"

Person B "SO YOU ARE SAYING THE WINDOW HAS TO BE RED? IT'S OBVIOUSLY BLUE!!!"

It depends what you consider hardware raytracing. is it all done in hardware? yes. is there "dedicated" hardware for raytracing calculations? No.

I'm fully expecting PS5 raytracing to consume more GPU resources then it does on xbox for the above reason.

Exactly. That's the difference between hardware raytracing and hardware-accelerated raytracing. One of them just can use raytracing, the other makes these calculations run faster in their own dedicated cores,

will PS5 and XsX take a performance hit if they were to implement RT? So a game would run at 4k 30fps with RT on, but will run 4k 60 fps with RT off.
There's a dedicated chip in the Series X for RT. So, no. Performance won't take a hit as I understand it. Can't speak on Sony side just yet. I'm sure they're rocking something similar though.

Serious question to all the doubters - what else can Sony use? NV RTX (obviously not)? RDNA1 that doesn't support RT? RDNA3 that doesn't exist yet? Both consoles will be based on the same AMD chips, anyone with just a bit of common sense knows it, but I guess fanboys will fight their battle till the very end.

GPU performance always takes a hit with RT.
the gpu actually has to render stuff, the RT hardware just helps with the actual casting of rays which calculate the path light takes

should I bring up the PS4pro again? GCN1.1 with added features of GCN 4 and GCN 5... doesn't mean it is GCN 5 based... because it is based on GCN 1.1

But if the GPU is powerful enough (in this case 12Tf in raw performance) and they add a dedicated chip to handle RT, is the hardware hit significant enough to even mention at that point? As I hear it, Microsoft added dedicated RT hardware so it can handle the bulk of the performance that RT can have on the GPU. I may have misunderstood. Hardware tech isn't really my bag. I find it interesting though.

look at Nvidia RTX cards. they have dedicated hardware that only does the calculation of the Rays... their measurment of this is "gigarays", I am not sure if that's a universally used term or something Nvidia made up... but it is telling us how many rays per cycle the Raytracing hardware sends out.
and even their best RTX cards with 10 to 12 gigarays have an up to 30% GPU performance impact... in early versions of games where stuff was less optimized it was actually bigger than 30%

the GPU actually has to render the final image, this means if you look into a mirror or a very reflective window, the stuff you see reflected needs to be rendered by the GPU as well, and it has to be loaded into RAM so you can't cull (unload stuff outside of the players view) as aggressively as you would be able to with no raytracing.

all of this has an impact on performance, no matter how good your RT hardware is.

Gotcha. So RT stays thirsty. Still hope its utilized a bunch in the new gen. Tired of games looking like plastic. Fucking yuck.

Been rocking Yakuza 0 on GP. Great looking game with detailed characters, but the overall synthetic, plastic look puts me off big time.

Man talk about weird analogies lol

What happened here is more like:

Window company: "Yes, we make the finest blue double-pane windows. I can confirm both Alice and Bob got last-generation blue windows from us"

Alice: "Indeed, I got last-generation double-pane blue windows"

Onlookers: "So Bob must have gotten single-pane windows"

Other onlookers; "Window company guy said
"last-generation" for both tho"

Onlookers: "That doesnt mean anything. He only confirmed they are blue. They can be any old blue window with an extra pane welded to it."

RDNA1 plus custom raytracing solution from somebody else. Could be Adshir. In fact I am certain that PS5 uses Adshir.


Does that guy on the main page look like out of a Sony exclusive IP?

uhm? no...

the quote goes literally: RDNA2 will support Raytracing in Hardware. Both the next gen Xbox was well as the next gen PlayStation, both will be powered by Radeon and both of them support Hardware Raytracing.

no RDNA generation of any sort was mentioned when talking about the consoles. all that was mentioned is features and that they both use AMD.
new GPU features can bet added to older GPU architecture. Raytracing is only 1 of many changes RDNA2 will have, if the PS5 only has a few of them but not others, like maybe a new manufacturing process and efficiency benefits from that and other optimisations, it is not RDNA 2

and in every single instance AMD avoided even alluding to it being RDNA2, as does Sony.
meanwhile basically every time the Series X was talked about by AMD or Microsoft, they specifically used the terms Next Generation RDNA, the same term AMD used for RDNA2 many many times.

That conclusion just brought something to my attention. Do you remember when it was rumored that Sony was using their own solution for Ray Tracing and NOT AMD's solution? Not having support for RDNA 2 might be the reason they had to go with their own RT solution, or the reason for not going to RDNA 2 altogether :goog_unsure: Assuming we can trust all these rumors.

I can see the posts now, Sony saves money by not licensing RDNA 2 and instead goes with RDNA 1 and develops their own custom hardware raytracing solution. "Sony's solution is better and more efficient" lol.

I don't get what that has to do with anything.

He just doesnt want to confirm anything when he is pushed like that. On the other hand u owe everyone an appology for saying the website lied and that quote doesnt exist .

You literally made a topic saying both consoles are RDNA2 using that writer as a source, and now that writer is telling you that he doesn't know if it's RDNA1 or RDNA2. I see it's not worth talking anymore to you, I will just put you on ignore.

also, EVERY GPU SUPPORTS RAYTRACING.

here is a raytraced image made on a freaking Amiga 500

all of this has an impact on performance, no matter how good your RT hardware is.
The "Gigarays" is just the amount of rays that can be cast per pixel, i.e. 10 Gigarays is 10 billion BUT this figure is not really accurate or representative at all. The Nvidia team went through some marketing hoop jumping to get to this figure as even at 6G on the 2070 would be more than enough to enable multi bounce RT at 4K even. They are including the recon element and it has almost become a "as good as x Gigaray" results, a discussion for another time.

The new consoles will 'likely' not follow the exact same Ray acceleration methods that RTX has taken but they ARE hardware accelerated and the biggest benefits here will come from the R&D behind it and multiple teams sharing knowledge, this is one problem where 9 woman CAN make a baby in a month.

so the way they use GIGARAYS (love that term btw.) is just their own weird definition
okay...

I don’t think it really matters .. if Sony is using non RDNA 2 day tracing .. they might be using this https://www.adshir.com/demos ( has a demo wish Spider-Man)

Which goes along with the rumor of a simpler version that’s “elegant”.

Prob what that means is most of the time it looks as good but runs with less performance hit .. but may not be as functional or correct as Microsoft DXR version.

Either way it’s good for gamers.

well I am still getting a fishy as fuck smell from this tech to be honest.
this shit looks way too good to be true, and then cloud computing is also mentioned many times but they also say this works offline and on mobile hardware at similar quality as shown in these demos

this tech is weird and I would love to see an actual demo released before I ever believe this works as well as they say it does.

They also said this at CES 2020:

“We designed it bottom to go after low-end devices,” said Offir Remez, executive vice president at Adshir, in an interview with GamesBeat. “We have multiple deals across console and mobile sectors, but we are not allowed to talk about it until the second half of the year.”

With Microsoft obviously taking AMD's raytracing (they have RDNA2 confirmed) guess which console maker doesn't want to talk about their console just yet?

Here is more detail about how LocalRay works, they even talk about it reaching 60 fps on a 5700 XT, which would be the equivalent of a 9.2 TF RDNA1 PS5.


I think the downside is that it can only do reflections and nothing else. It can't be used for more realistic shadows or global illumination, it's specificly built for reflections.

Ps5 is not 9 tf or rdna1 . I know it’s hard for you to believe but just like other things I will highlight your lies later 👌👍😜
