Tests on RDNA1 show AMD scales badly to clock but well to CU. Extrapolated to estimate XsX/PS5 differences

Theres so many threads on this and I was asked by a mod to recreate it with a different title.. to ensure this one isn't blocked I've named it exactly like another thread.. so here it is

Tests showing that under RDNA 1 AMD hardware scales very badly under clock but very well to CU.

Gaming Bolt is saying it does not expect Sony's over clocking to scale linearly, that XSX's 15% GPU advantage on paper may actually be 25-30% in real world performance, and that it expects PS5 to run in 1800p often.

It's at 9:15-11:25 in the video below. Just one view but interesting analysis.

This is the problem with Sony's approach of tell but don't show. Not everyone is going to buy Cerny's powerpoint slides.

You're right OP.
Xbox apologists should respect PS5s SSD and recognise it's superiority, it'll improve games across all platforms eventually through the trickle-down effect.

....And Sony users should just respect the superiority in every other specification?
 
Gotta throw in the towel sometimes, OP. Xbox is a stronger machine, life goes on. No point in creating an another thread on this. If you love Sony this much you should just go and work for them. There is no honor in worshiping a brand.

If the difference is 20-30% in real world rather than 7% ... that's going to be VERY noticeable.

Spergy percentage battle aside, there's going to be a noticeable difference because the Xbox was expertly crafted and has advantages in all the areas that matter.

Multiplatform titles will look near identical

PS5 will have the best 1st party visuals since they have Naughty Dog, Insomniac Games, Sucker Punch, Santa Monica, Bend and Guerrilla Games

Kojima is probably making a PS5 game right now too

The SX will be doing the EXACT same thing, just with a slower SSD. Just because you can access assets doesn't mean you'll be rendering them better than a GPU with even more horsepower.

A 2 TF difference between the pro and 1X shows us how wide that gap it brought, and it'll be an even wider gap this if Hellblade 2 is anything to show us so far.

30% difference?

Lol. This is not RDNA1. It's RDNA 2.

There's no doubt it'll be stronger but that's just silly. With RDNA1 it wouldn't even be possible to run at 2.23Ghz on a closed box for starters.
 
this is really getting to the point were the discussion are becoming absurd.
I am a fond believer that we will have a great time with games like God of War. Let's switch the paradigm a little bit here, we should focus on games. The new capabilities will deliver very nice experiences for absolutely fantastic franchises from brilliant studios.

Let's start talking about games again. This is a forum about gaming not a forum about terraflops and console forum, no?

Well look at the One X vs. the Pro, because of the customizations Microsoft did to the GPU and memory interface this on paper 43% more powerful GPU was actually denoting average resolutions which were 75%-80% higher.

On paper doesn't tell you everything, but it's clear to see where issues can arise and where performance extrapolation can thrive.

It's true on paper isn't everything and xbox seems to always punch above its spec sheet compared to playstation.

The video included in the original post seems to align to this.

But it's not just the GPU that is better on XBoX. CPU is clocked higher, it has 50% more RAM, higher bandwidth, etc. The situation is quite different.

Courier simulator 2?
 
How it is gonna be:

- ps5 runs at 1800p what runs at 2100p on xbox
- framerate same
- loadings/pop ins/LoD/object density and OS snappiness 2.5x faster on PS5

Yeah, but the GPU is better here, the CPU is better here, the memory setup has more bandwidth for key tasks like rendering... It's not so different.

GPU is better but we don't know exactly by how much since there are tasks which are better suited for higher clocks than more CUs. Watch RedGamingTech's breakdown video. There are unknowns yet. CPU performance difference should be negligible if both are the same internally, which they probably are. Memory setup has higher bandwidth for a part of its pool, not the whole.
 
While I am enjoying ribbing the PS5, truth be told there will some amazing looking games. This tech in the hands of ND, SMS, GG, Insomniac etc is going to legit create masterpieces.
Its not as strong as the XSX, but in this era of diminishing returns I'm not sure you could tell the difference side by side.

But Sony peeps need to accept that MS went balls out and put together a beast of a console. Its the tech leader this gen. Ever since Phil took over and they put out the XOX, it was clear they were not going to stuff this gen up.

Yeah, yeah, SSD in XSX is faster.

EDIT : Well, in the minute 17:30 of the unveil, when talking about kraken, Cerny referred to a custom decompression chip builti n the IO unit, the one that in a very specific case could allow to reach 22GB/s

The SSD in the PS5 is 125% faster than XSX's off-the-shelf solution.
They not even the same SSD gen tech wise, compatible drives for PS5 are not even out yet.

Stop it. I'll give you a wet kiss and tell you how pretty you are if you don't stop it.

Listen to the video. Xbox Velocity Architecture will allow 100GB to be available instantly from the SSD. Plenty of room for devs. Sony's SSD is faster but it lacks in other areas. This is all just theory right now. Show me a game that can be made on one SSD and not the other.

MS official specs of 2.8GBs are already taking the software behind it into consideration. And that's an order of magnitude slower than PS5.

Just accept it and move on.

Edit: a game impossible to create on xsx might be God of War 2 I suspect. Or spiderman. They are gonna go balls deep on that 125% faster SSD than Xbox and you bet there's gonna be some crazy shit happening. We shall see my friend.

I'm sure we'll see some fancy ray tracing on xsx too not possible on ps5, so there's that.

Starting to feel like journalists are throwing around wild speculation about the wide power gulf in order to goad sony into releasing more info to clarify. Thereby giving them more fodder for their articles. Give it a rest yearnalists.

Xbox does not need apologists for XSX or as that guy who just got banned in ResetEra said

I just wanted a reason to post that line, so ignore this.

We've seen no gameplay videos of Hellblade 2

The Xbox One X and The PS4 Pro rarely showed any significant difference besides the few outliers like Red Dead Redemption 2

No gameplay? Cerny won't even show us the damn box. We're like 8 months out and all he's got are powerpoint slides and wild theories. MS put a physical box in DF's hands to evaluate. Then showed us the box running. Cerny talked about a box and then refused to explain the cooling when asked. Not sure we should be demanding that MS show more at this point.

8million pixels or 4K vs 6million pixels on PS5. Both are pushing crazy amount of pixels on screen.

Just for reference. 720P is 1million and 1080P is 2 million.

I was replying to the guy that said the gap will be big if Hellblade 2 is anything to go by

I know we haven't seen any games from Sony, if I were them I would've showed a few trailers already because the moment they do, a lot of this concern will die off

Will it? And when will those games come?

Anyone still sold by Sony announcements must realize most games won't come until close to the end of the gen.

If they don't put a date on it don't expect it soon, and if they do expect it will be delayed.
