So Sony big secret according to you is its RDNA1 based? and that you are a developer and engineer to have known this as a fact?

... so now you know Sony's big secret
They redesigned the chip from RDNA1 to RDNA2?
It sounds like a pretty big change to me.

I am not stating any facts in my post, I am asking a question. I want to hear what experts like you think. How does it work? How hardware with one instruction set is going to execute a different instruction set? I find it mysterious and quite fascinating.
A possibility, which we can't exclude. Like any other explanation. And it will probably remain a mystery until PS5 hardware will be mass available for anyone to dissect it.

Oberon was also RDNA1.
You guys are misinterpreting this. Rogame was just stating what data was listed, but there was not a lot of context for the RDNA1. Ariel iGPU testing profile rationalizes this more or less, because we already know Ariel was the RDNA1 chip and for sake of regression testing they'd need to run its profile as iGPU on Oberon. We never got much info on C0/E0 either other than a change to the RAM memory controller.
We also already know both systems are custom RDNA2, i.e they aren't using everything that is going to be on the PC RDNA2 side. The extent of which we don't know, however. As to anything about PS5 upclock being reactionary, I never suggested that. We don't know if that was the case, but the highest probability is that it wasn't in reaction. However, we do know they were still using a fixed frequency strategy up to some point going by what Cerny said, that probably includes at least the first Oberon revision, too.
Ultimately whatever was the motivating factor for increasing the GPU clockspeed, or if it was planned/not planned, it's water under the bridge at this point.
That's not necessarily how I read it. Seemed to me he's just saying that there will be other factors to the systems other than their theoretical peak TFs that will influence their overall performance. Whether that means a delta of "a bit" or more than that we don't necessarily know yet.
However we already have some paper numbers on various aspects of the systems like the TF delta (18.2% - 20.6% favor XSX), CU delta (44% favor XSX), SSD raw speed (125% favor PS5), RAM bandwidth (25% favor XSX on 10 GB), and (hopefully) a pretty decent grasp on how much weight these things have to overall system performance...for the most part. Where you want to see it from there could come down to preference, if you want it to.

Don't stray off topic, you said it's Sony Secret, for you to say you know a company secret means you have insider knowledge, so now if you are saying its not a fact, you are simply spreading FUD then.

Has to be since RDNA2 wouldn't have been available at the end of 2019. Not to mention they said it's RDNA2 Based.

I put a laughing smiley face to show that it was a joke about Sony's secret. And you are the one actually trying to blow it out of proportions instead of having a constructive discussion on how Sony plans to implement backwards compatibility with different instruction set in hardware.
So please stop derailing the thread.

I'm sure that's the dream, probably best to assume that PS5 outsells Xbox regardless of pricing or models available.
Seems like you might be able to shave off $200 tbh. 360mm2 APU vs. 260mm2 or less, cheaper SSD, less memory, smaller PSU, cheaper MB, cheaper cooler, cheaper case, etc. Lockhart using a derivative APU would change things, but would likely add TF to the system, pricing could be different if they went that direction.
Microsoft is doing it also not a big deal. AMD probably had a hardware customization for BC that Microsoft and Sony tuned to their needs.

RDNA2 supports wavefront sizes 32 & 64, XSX needs this too for bc.
RDNA2 is not only confirmed by Sony but also AMD confirmed in one of their presentations next gen consoles are RDNA2. Leaves no room for speculation or crazy theories.
Misinterpreting what?
Navi10= RDNA1
No RT bespoke hardware= RDNA1
What other interpretation is there?

I don't doubt Lockart will be less expensive to manufacture. I only take issue with the idea of XSX subsidizing lockart
A system that sells a fraction of the other can't possibly subsidize it. It has to be the other way around

Again with RDNA 1 really:
1.- Cerny and AMD already said PS5 use RDNA 2
2.-Cerny even specify the colaborate to make RDNA even say any change from AMD they need to tested it,
this one of the reason of why they just say all titles were 100% compatible without issues but they need to tested
Note: this start smell like some discord

Well actually it is a big deal. Because we know how MS does it, it's not a secret. They don't have native hardware BC, they use custom hypervisor/virtualization, so XSX hardware does not need to support exact instruction set of XBox One to have backwards compatibility.
What Cerny mentioned is native (assuming hardware) backwards compatibility to PS4/PS4 Pro, which from engineering standpoint is completely confusing. It is OK for CPU, because both Jaguar and Zen 2 cores support AMD64 (x86-64) instruction set, so you can have native BC on CPU. But if GPU is RDNA2 based how did they manage it to run GCN instructions used in PS4/PS4 Pro? I for one eagerly await PS5 release to get answer on this question.
As I said above XSX does not use native BC, so it's not an issue for MS. However if AMD and Sony confirmed that PS5 is RDNA2, then how did they achieved native BC with PS4? I would love to hear some theories from engineers on this thread.

Actually as I said it is now hardware based not emulating like the one x.
" It likely comes as no surprise to discover that Series X can technically run the entire Xbox One catalogue, but this time it's done with no emulation layer - it's baked in at the hardware level. "
Inside Xbox Series X: the full specs
This is it. After months of teaser trailers, blog posts and even the occasional leak, we can finally reveal firm, hard …

Wow. I didn't even know this interview even existed. You could tell Mark Cerny found Fallon a little irritating. Cerny always likes to deliver his speech very smoothly and with a good explanation and style, opposite of what Fallon is. I'm curious to see if they'll market the PS5 in such a way although I feel the times have changed even though it's only been 7 years.PS4 demonstrated on Jimmy Fallon - watch

Just because they have more overhead in their BC doesn't mean GPU does not execute wavefronts 64. Its just legacy support for compatibility PC games need this too
Anyways we strayed from the original discussion: Consoles chips designs (architecture) and specs are set years in advance, theres no reactionary measures as you suggested .

As I know an Instruction set is not unique for architecture can be used in different architectures both internally can work different of courseActually as I said it is now hardware based not emulating like the one x.

this requires work for both part (AMD and the console manufacturer).
Probably AMD left some of those for the gpu of both consoles in order to make the BC as easy is possible that is one of the reason of
why both GPU are custom.

If so I'm really thinking of buying one instead of the SX. Should be great for the bedroom. And if it looks like the Cube, even better!

He is a YouTuber covering video games. So normally he has access to event when they present new games. He clearly says that there's a lot of news expected this week. He kind of imply it's related to next gen but that's not clear as he is under NDA probably and he cannot say what those videos are about.

I know this isn't the thread to ask this question, but i don't see any other thread to ask this question fearing I might run into a spoiler. So you're all aware that Last of Us Part II spoilers are out in the open with cinematics. Any idea how it got leaked?
Maybe Microsoft shows us today Lockhard and next week games. They revealed the specs for XSX on a monday. They could do the console today and are able to just show games in may.

How much do you think RDNA 2 is going to improve in the IPC field compare than the first generation?
I think should be around 5%-10%.

Of course. PS5 will still be the lead platform as PS4 was this generation. What I'm saying is that, since devs hace to do the Potato PC version they can use that work to make the Lockhart version as well. Look at Sea of Thieves, for example: released in two machines with a 4x delta. Or a multi platform that runs in a 2080 ti and in a 960.

Adrian Bentley Lead Engine Programmer at Sucker Punch Productions talks about the I/O and streaming issues they encountered during development of Infamous Second Son. Not sure what Dictator is going on about, but next-gen will undoubtedly alleviate most of the problems he talks about.
LMFAO who would've thought.
Pretty sure he and Cerny talked during the preliminary stages of PS5. Everything he talks about (in 2014!) Cerny addresses.
Darren Bridges, Senior Designer at Sucker Punch talks about making Fetch feel faster. Obviously, HDD was big problem.

BOM price for PS5 and XsX isn't that different (Zhug said around PS5 is around 20$ cheaper) so I don't expect any price difference. If Sony will come up with 450$, Microsoft will match.

I've read two theories on this: 1) The disgruntled employee Jason mentions in his article is the source of this. 2) OR the leak is being done by a company in Brazil responsible for localizing the game in Portuguese.

Remembered reading this on R AMD recently. Its basically ISA, Instruction set architecture. The drivers that interact with the hardware and API developers used. Apparently RDNA2 ISA can run GCN.

Of course yes. I still think it'll include a player.For people like me who love to collect the disc if that doesn't has blueray bay that is a deal breaker also for people
who want to use his disc of xbox one or even older.
But understand for people who only wants digital is okay or doesn't plan to have soon a 4k screen.

He said was $20 but in the low price he predict for XSX so could be more.
But I am also thinking both console will be around $500.

Yeah, sad how the narrative changed from "We got more TF!" to "But we also got this cool SSD in our console, not just Sony!" to "Yeah, we heard that you actually need some games for a new console, let's do that!"

I think should be around 5%-10%.
if ms wants Lockhart to replace x1x then it needs to be at least 25%. Rdna is 25% more powerful per flop than polaris gcn which gets us to 5 tflops. You will need another 20% to get to 6 tflops so it can run x1x games at the same settings.
