PS5 Speculation |OT12| - Aw hell, Transistor's running this again?

RDNA 2 supports hardware-based ray-tracing, a first for AMD. If Sony's using AMD's RT solution then of course it's going to be RDNA 2, just like it is for XSX and PC.
Dude, do you seriously think that anyone with the name Tim is TimDog? <rolls eyes>
That guy is so obnoxious. I am on the west coast right now, that dude is on the East coast.
We are two different people.
Yeah and that's a first in consoles, we haven't had video game consoles with built in hardware raytracing before, this is the first generation.
Exciting times! :)
Yeah, basically, lol.
A very valid theory.
Also...Matt said hardware rt for PS5, Klee said vrs for both.
Tin foil hat time...they must have both seen RDNA 2 on something or heard about it.
They combined to form Voltron on our ass.
That is just not true. If we just use linear logic then any calculation of ppw increase between GCN and RDNA1 doesn't come out to 50% gains.
If we look at it from a Teraflop per watt the RX 5700 XT (RDNA1) has barely better power per watt than the Vega 64 (GCN). the 5700 XT runs at 225w to create 9.75 TFLOPS, or 0.043 TF per watt. The Vega 64 runs at 295W to create 12.66 TFLOPS, or 0.0429 TF per watt.
Of course that makes no sense because it doesn't take into account IPC gains from one architecture to the next. As shown by almost all benchmarks 5700 XT performance in games is 10-15% better even though it has a large TF "deficit".
Maybe we could calculate the CU power per watt? Still doesn't work out to 50% because there is no perfect metric for us to compare two different architectures.....
Here are the two most powerful GPUs from AMD GCN and RDNA architectures respectively:
Radeon RX Vega 64
Next-Gen CUs 64
Base Clock Rate 1247 MHz
Boost Clock Rate 1546 MHz
Peak FP32 Perf. 12.66 TFLOPS
Board Power 295W
AMD Radeon™ RX 5700 XT
Next-Gen CUs 40
Base Clock Rate 1605 MHz
Boost Clock Rate 1905 Mhz
Peak FP32 Perf. 9.75 TFLOPS
Board Power 225W
I'm really curious how you would calculate these in some linear method to come up with 50% ppw gains and completely ignore IPC......
Ms has collaborated with Nvidia (and likely AMD too) to create a RT api that can be used on Vulkan. Likely that Is the unified api AMD talked about. (And it means we should see the same RT apis across all platforms)
I'm glad the Github leak has been put to rest. Now we can get back to looking forward to both consoles being on par with each other which to me is the best case scenario.
I'm confused why people think RDNA2 being confirmed for PS5 changes much of anything. For final PS5 to be something other than the Oberon chip shown in the GitHub data, one of the following has to be true:
I don't see that PS5 being confirmed as RDNA2 makes any of those three possibilities more or less likely.
- Oberon E0 vs Oberon B0 has very substantial architectural changes atypical for steppings.
- Oberon B0 shown running the back compat tests wasn't the full chip configuration (disabled SE/CU hypothesis, this is where I am).
- There's another, secret chip that we've never even heard a code name for that represents the final PS5, and Oberon was an entirely different line of development used only for BC (Doctor Avatar this is you, right?)
I don't see that PS5 being confirmed as RDNA2 makes any of those three possibilities more or less likely.
Yeah, it may have been expensive for them to do but investing that money to make sure every person that bought a PS4 can bring their library with them is huge and clearly Sony sees it as important.
The 50% GCN bump was bogus anyway because they were counting process gains too. RDNA 1 to RDNA 2 is 50% on the same process. IPC is baked into both numbers, per AMD's breakdown of said gains.

Buahaha and yet people are still talking about it. Madness
Oberon has been labelled as Navi 10 in other leaks. So RDNA1. So not PS5's APU if PS5 is RDNA2.
Oberon is in a super advanced state compared to Arden in GitHub despite being the same arch? How?
Despite claiming to be "logical" and "data driven" you're both being illogical and making assumptions that have no basis other than to confirm your opinions.
So we have a RNDA1 chip line in ariel/gonazlo/flute, then get super advanced developed Oberon, also Navi 10 (RDNA1 GPU) and exact same config as the RDNA1 line, with zero mention or any evidence for RDNA2 and you're telling us it's logical to conclude it's RDNA2?
GitHub is dead man, give it up.
Now, I don't speak fanboy, so please indulge me... Why would they be referring to a console that isn't even officially confirmed to exist?
My God, some of the people in here! I should really stay away.
Apparently , in the Q&A AMD segment they stated that aspects of 7nm+ have been rolled into base 7nm+ spec from tmsc
Matt never said move past it, he said it's not confirmation of anything, which is true. Nothing can be confirmed until it happens.
I don't know what that is supposed to mean. We both play video games?
Other than our first names being the same and living in the United States (how many Timothy names are there in the USA), we have nothing in common.
If people said that something says PS5 and it mentions Direct X code, that has nothing to do with Sony.
Yup, a certain poster went as far as tell me I had no idea what I was talking about and how my contributions to these threads were average at best. Because I was saying over 200W consoles.
Operon far ahead of Arden is a hot take I actually had to chuckle about.
The data leaked was test data for a script a clueless intern was programming and put the data on github.
If you look into the script he randomly accessed data, even with wrong references
Which means data for Ariel, Oberon, Arden, Sparkman and all the other chips that were in there was not the complete picture.
Nobody ever said it was a complete picture.
But what was interesting about the leak was information in some of the comments. Like the 36 CU full count info for that 2000 Mhz mode and the other modes for BC.
I actually never draw any conclusions from Github about the architecture. But I always was of the thinking that both companies using the same base technology. Did not change a bit. After Xbox came out of leveraging RDNA 2 I am on record here to say PS5 will use that too. You can look into my post history!
Arden at that point was highly likely RDNA2, I assume Oberon as the successor of Ariel was that too.
And this answers your questions.
AMD clarified the 7nm thing. They intentionally used a generic "7nm" without any regards to which version

I’m glad to see we’ve moved pass thinking the Github leak was confirmation of anything.

Pertaining to 1.) An AMD link was posted here over last weekend showing that in AMD terminology, letter changes are model revisions with new model numbers. The numbers are the steppings.
I was pretty sure it was not.

The obvious question is why is Sony not providing the answers here. If the PS5 is RDNA2, then why isn't anyone from Sony posting this out to the public?
Why do we need to hear this from a third party?
The marketing department from Sony has changed a lot from 2013 and not in a good way.

you haven't read the last two pages then...
we are already back at 9tf for some

I do agree, AMD is counting a huge amount of things to come up with their 50% number from GCN to RDNA1. They are counting process gains from 14nm to 7nm, IPC gains, and increased efficiencies in power required to push up clock speeds. If they really have a 50% PPW increase from RDNA1 to RDNA2 with a much more limited process gain (maybe they are talking about moving from 7nm to 7nm+?) then they must have some pretty great efficiency gains or they have found ways to massively increase clock speed with minimal power increase. Maybe both? Or all of the above? Can't wait for some benchmarks on actual RDNA2 products......
Sony will talk when they want to talk. Their silence I believe is not indicative of anything, just that as they said in the ps5 website they are just not quite ready to give more info right now, for whatever reasons.
We were told, some didn't listen...Next-gen PS5 and next Xbox speculation launch thread |OT8| - The Dark Tower (See Staff Post)

The 12-14TF train is going ahead, full steam
Yes I believe in GitHub too my man, let the GitHub believers unite! #GHBelieversRiseUp!
