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

So, has anyone at Sony confirmed officially that it’s RDNA2 or otherwise?
I mean, I couldn’t frankly care less, but it seems to be firing some people up, so best to nail down the truth.
 
If this is indeed accurate, it seems to br RDNA2 with cut features, effectively making it not full RDNA2, hence "between RDNA and RDNA 2".
My banking is there taking a gamble on the ssd to much then. Theoretical i know its not a gpu but maybe can do some things that a gpu would do

Mark Cerny actually said that the PS5 GPU is "a custom AMD GPU based on their RDNA 2 technology." Cerny never said that it was RDNA 2, but rather based on that architecture. Cerny customized the PS5 GPU to his vision to make the PS5 run more efficiently, better, and faster by getting rid of all the various bottlenecks and a blazing fast SSD. I trust Cerny's vision, and for him to deliver an awesome product. The PS5 is highly customized, and doesn't use the traditional PC parts, and it's better for it.

so it’s even better than RDNA2? We should just cut to the chase and call it RDNA3

Heads were rolling when people speculated before that the ps5 wasn't full true rdna2... and now we have confirmation from an actual Sony employee... of course the goal posts shift and say either "no big deal" or "i wish people would stop this shit" ... stop what shit? Discussing huge revelations that were hidden from fans by sony and amd to make the ps5 technology look better than it actually is?

Like I said in an earlier post everyone is gonna buy the system regardless, it's the next playstation. Just buy it play the games and be happy.

Honestly, whoever is in charge of sony right now should be fired. They literally are giving bad press when they only needed to release their console and win the gen again.

By the way, this information doesn't contradict what has been revealed previously about the PS5's GPU; we've known for quite some time now that it doesn't have all of the features of RDNA2 but only the features that Sony determined to be truly beneficial to a console (rather than a PC) and that these features have been combined with proprietary technology exclusive to PS5.

Depends what those cut features are. But honestly if they don't matter to a console then I don't see how it was a bad thing that they were removed.

Ok everyone .. why so serious?

RDNA1 , 2 , 3 or 50 who cares!! .. you are going to enjoy the games the leap in graphics it’s more powerful than PS4 pro , imagine what next after GOT and TLOU2 .. the same goes for Xbox whether it has fast SSD or not it’s loading screen for god sake it’s not a big deal if you have that or not I’m not gonna judge the game by it’s loading screen !! .. wake up and be reasonable stop the nonsense
 
Is the teraflop performance 1:1 between the two consoles?
Not anymore.

I dont even know how we calculate the difference now... its RDNA1 with additional RDNA2 features bolted on.

Don't think it's fair to only use RDNA1 for ps5 to measure difference to XsX.
Not sure if you guys are being serious or not but there is no such thing as RDNA or RDNA 2 TFLOPs. The differences in performance are down to other features such as IPC, mem bandwidth and other factors.

I'll still support PlayStation but this stuff is really pissing me off....

The incompetence between the way they handled TLOU2 leaks, the bad marketing job they did for Ghost of Tsushima, putting stupid games like Goodbye Volcano High in the PS5 reveal (I mean WTF)!

Then all of the bad messaging with the console.... if this is truly not full RDNA2, then they better be charging much less than the competition.

I'm still not totally convinced this is real cause we've seen a lot of misinformation put out there about PlayStation trying to damage the brand from..... well you know!

Anyway, if they start pushing streaming, I'll be done with them.... I'll just go back to being Nintendo only.

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.
 
If true, then Sony really dropped the ball with the PS5. Not only will PS5 have a 2TF disadvantage against XSX, but even the architecture will be gimped, with features entirely missing. Just imagine how much of a disadvantage they will be in once Machine Learning becomes a staple of next-gen games and PS5 is completely missing out. Not looking good.

I think we should wait a day or two and see if Sony makes and official statement once this inevitably makes the cycle on social media and gaming sites.

Because this could end up being a enormous downside to the PS5 as it would be missing out on some massive features and I doubt this sort of information would be this openly divulged by one of the engineers.

I don't understand, are you saying that the Japanese public feel they have been lied to?
 
Imagine believing fake fud from xbox era discord instead of cerny and amd and Lisa su. PS5 is Rdna2 until cerny or Lisa su or amd says otherwise And not a fake PM created by xbox era discord
Its a Sony PS5 principal engineer employee's own comments. Has nothing to do with Xbox era. Cerny has never mentioned Machine Learning. Why? Sony has not mentioned whether the SSD speeds are peak or sustained. Why? Sony has only confirmed PS5 uses RDNA 2 in some fashion. Sony has never claimed PS5 is the most powerful next gen console. Why?

Phil has stated multiple times XSX is the most powerful next gen console. MS has confirmed the SSD speeds of XSX are sustained performance. MS has confirmed XSX is RDNA 2 and gone into detail what those RDNA 2 features are. MS has confirmed machine learning in XSX.

I can't believe the part mentioning no ML. The other stuff? Yeah I can see some precedent for it and I think there's a timeline to support it (I also don't think it's really a bad thing at all because it'd still mean it has many RDNA2 and maybe even some RDNA3 features while being on a more efficient node process, same as Series X. They are both "essentially" custom RDNA2).

But no ML? Why gut that out? The Pro had ML support; maybe Sony figured from their internal studios it wasn't worth implementing, or they used the budget on the GPU on other things like the cache scrubbers and customizing the GE and PS? I just can't wrap my head around the possibility it has no ML but if that's true I think that'll be a big negative down the line and would be curious to see what things they could implement to make up for it (if those techniques exist).

Figured there would be at least similar FP16 ML support as the Pro, even if ML is not a focus for Sony. I'd love a full technical feature breakdown on both PS5 and the Series systems i that regard but that's never going to happen :pie_roffles:

Again, I knew there would be some differences between the systems and we can clearly see that, but I didn't think one would be as drastic as ML/no ML whatsoever.

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.

The game will look similar. Power difference is way too small for there to be a huge disparity.

Games at lunch practically never take full of advantage of the hardware. Especially third party games. You won’t see a big difference until a few years down the road. If then.

Is that why RDNA1's architecture would be similar to Nvidia's Turing architecture in its teraflop count but perform much worse?
 
Cerny said he customized a GPU based on RDNA2 and if AMD releases a GPU similar to the one on PS5, then his collaboration with AMD was successful. Whe he says this, he knows AMD will release a PC gpu similar to PS5 and that his collaboration was successful.

Also, the rumor suggest AMD will from now on do 40 CU chips in some design stacked over each other with some new connection technology that I forgot its name. So, it's clear that PS5 gpu is far from being a useless old tech.

Time will tell

Neither of us can say that with any certainty. Until these machines are out and we can see them operate, it's just wishful thinking and educated guesses.

So like I say, IF this makes any difference, we see it on Thursday or probably not at all.

They perform similarly . Not that it matters because their architecture is totally different. What you’re doing when counting FLOPs is this:

Shaders* GPU Clocks*2.

That’s it. You’re ignoring dozens of other factors. Memory clocks and Core Clocks aren’t the same for instance.

This whole TFLOPs wars is silly. You can compare them assuming their feature-set is relatively similar as generally, the one with the higher compute will be a higher tier card which will also lend it to having higher levels of other features.
