Next-Gen PS5 & XSX |OT| Console tEch threaD

Status
Not open for further replies.
Ronald has said SFS is a new feature and an effective multiplier on available system memory and I/O bandwidth, resulting in significantly more memory and I/O throughput. These are not my words, I'm just quoting Jason Ronald.

There's also James Stanard (MS engine architect) further confirming what SFS does. According to him compression and SFS gains stack.

It's not hard to understand what MS engineers have said. The implications are obvious but I guess some people dont like to hear what MS engineers have to say, because it's already established here XSX is bottlenecked like PC (and lets not forget about bruteforce🙆‍♂️), while PS5 is more efficient and better engineered in every way. SFS suggest the otherwise, so now you guys are trying to tell me SFS will not work like Ronald has said, or SFS is nothing new.

PS5 / XSX launch is not long from now, so we will know how performance looks in real games without any biased interpretations of PS5 / XSX architectures. Personally I expect both consoles to be extremely close. Maybe even digital foundry will be not so sure who is the clear winner. I guess sony fans dont want such scenario, because some of you (like for example FieRR) have already visualized a reality, where PS5 games looks like next gen games compared to XSX thanks to SSD 🙂🤣👌.
You are not quoting you are interpreting with your words what he said and looks like is harder than you think to understand it. Quote is just add the tweet without any opinion.

The number 2x-3x came from the case of stream all the textures vs using SF for all the textures, thing which in the reality is not possible according to the same Microsoft.

Yes is a new feature which use hardware (already present in 2018 GPUs) because before the dev had to create its own solution based in software which is less efficient because yes
already some your AAA titles use this kind of technology is not the fault of this forum you don't understand that.

Virtual texturing is a technique that allows the use of arbitrarily large textures within the limited physical video memory. Through a paging and streaming system, only the
currently visible parts of a mipmap chain are stored in the video memory while the rest of the data may reside in any other memory or storage device.

James is not lying:

Yes, they stack : you can use SFS with the compressions, he only never said this cannot be used for each call of textures
Decompression amplifies data beyond the raw speed : is true your quantity of texture is bigger when you compare against any engine without a virtual texture solution
SFS is a strategy for not wasting bandwidth on unneeded textures : is also true, but that doesn't mean you remove completely that

And if you think the SSD doesn't improve the quality of your assets please inform of this to Xbox team which in the last weeks are foccus in that.

In some way you get a good feature of XSX and transform to the new hidden GPU as 7 years ago.

Let's put it in this way is like I say the PS5 barely will use the memory GDDR6 because can load directly to the cache of GPU. Is the same I take a good feature and transform in
the holy grail of my crusade.

I been thinking, MS can do a refresh Series X+ in 2 years down.

Just unlock all ram and cu, clock them higher. And boom 14TF+, 20GB ram at 640gbs, 16threads at 4Ghz, faster SSD.

Really smart desgin. :messenger_peace:

What’s the point? It already can do 25TF and 48GB/s I/O. Let’s wait for tomorrow I’m sure it will have 64 GB of RAM @ 1Tbps somehow.

Kidding aside, like you suggest,
some minor upgrades a few years down the line with significant clock upgrades and a good price and that’s good enough.

Yap, when you see MS focus on compatibility in their ecosystem, this makes the most sense.
Catering to consumers' desires to buy newer faster toys.
X+ may even be out early summer 2022!

It costs them next to nothing in a way.
But the visual gap between PS5 pulls even wider.

a reduction in required data does not increase the throughput it reduces the required data .. are you new here?

not only does SFS increase the efficiency of disk IO is reduces the in mem footprint..

I'm not disagreeing with you. :messenger_tears_of_joy:

You might have missed the part of the convo where MS was "trying to lie to users and claim that throughput was increased" and that they were "hiding the real numbers"

I was making a note that their throughput is what it is.

You are talking about 48 CUs GPU but with much slower clock, while I was thinking about 48 CUs with the same 2200 MHz clock speed

48 CUs 2200 MHz = 13.5 TF
48 CUs 2100 MHz = 12.9 TF
48 CUs 2000 MHz = 12.2 TF
48 CUs 1900 MHz = 11.6 TF
48 CUs 1800 MHz = 11 TF
48 CUs 1700 MHz = 10.4 TF

You want to tell me Sony would go even below 1700 MHz on 48 CUs GPU?

And BTW. I wonder why 2080ti is clearly faster than RTX 2080, because according to Cerny smaller GPU with higher clock should be faster, but that's not the case with 2080ti.

I think it is obvious once they knew they could increase the clock speed to achieve 10TF while still maintaining the thermals, noise with their design. They went will the smaller and cheaper chip. It serves them both purpose. But if I had to choose from your list. I guess 48CU at 1.8Ghz is probably the sweet spot.

I always had the theory that while the SSD speed will be the same the size of the drive could be smaller. Like maybe 500GBs for the SSD and then have the option to expand it like with the XSX.

It seems pretty logical to me.
Good point. Do you think consumers would be okay with just 500 GB of storage by default? I wonder. That’s like 400 GB after the OS takes some away. Isn’t Call of Duty Warzone like 200 GB now with all add ons? Maybe a 500 GB SSD is enough, but I think it might be a bit too small. Idk.

I think the reason the SSD for Xbox Series X is slower than the PS5 SSD is because it was made with cost in mind for Lockhart. I doubt the 1 TB SSD Xbox made costs THAT much more than it would if it were just 500 GB. I’m just speculating, but I think if Xbox had designed a SSD just for Series X (a ~ $500 console) they could have built a more expensive SSD.

I suspect they held back and cut cost so the same SSD could be used in a less expensive console. That let them spend more on their 12 TF GPU.

I think almost everything Microsoft is marketing about Series X can be used to market Lockhart. Velocity Architecture, 100 GB instant access, BC Pack, SFS, Quick Resume, Smart Delivery, etc.... it’s all applicable to Lockhart. I think Xbox will say Lockhart (Series S?) can do all the same stuff Series X can, except 4k120 (4 TF vs 12 TF) and (I think) play discs.

I think Microsoft has built up the various buzzwords and marketing hype around their high end console carefully and intentionally in order to also market their lower end base model console. That’s why I bet the SSD, OS, etc are the same.
 
I don't know if this was already share it but will good the see:

In the BC department until now looks like Xbox is company to see so let's check how much improve in the new console.

I think 500 GB is a good choose I mean, the games will be smaller than in XSX (not 4k textures) and the new compression, the remove of duplicated assets
will help a lot in the size.

And if you want to have a console very cheap, 500 GB and without disc drive for the first gen of XSS (later they can add more SSD) could be an smart move.

So now the XSX has 48 GB data streaming?
Goodness, Microsoft can practically bend the laws of physics with software.
Imagine if they came up with something like Thunder Dash Motor (TDM™) that could allow for 1000% overclocking without drawbacks.

Shiet, what if I'm just feeding them ideas at this point, they are magicians after all :messenger_hushed:

To all those claiming they know for sure the ps5 is superior ... i was wondering
how did that 13 tf hype train work out?

CHOO CHOO! For your ticket aboard the Hype Train, Simply REACT to this comment.

@davidjaffe bro, you getting on this train?

ps4 pro claimed 4k gaming ... failed

xbox one x claimed 4k gaming ... has many true 4k games quite a few at 60 fps

xbox claimed xbox one x worlds most powerful console .. it was

xbox claimes xbox series x worlds most powerful console ... it is

Its funny how when it actually comes to xbox making false or misleading statments .. there are no recent examples... but yet here we are with legions or train crash passengers trying to accuse others of being deluded.

The SSD is superior there are no two ways about it, we know the specs for both this isn't a guessing game, I don't know why xbox fans can't live with this fact.

you shouldnt be surprised, xbsex is 25tf console with 100gb of vram

we are lucky that people didn’t read “100gb instant access” as 100 gb/s streaming

To be fair PS4 Pro has some native 4K games but yeah, Xbox One X has more. But there are some games where not even XOX can reach that resolution so we could argue that both Sony and Microsoft are deceiving us when they claim 4K gaming.

LoL are you for real? Sorry but no. In my previous post I have literally copy and pasted Jason Ronald own words from his article (but without BB code) and you are still saying I'm interpreting what he said with my own words. When it comes James Stanard tweet I have posted it without adding much besids what he already said (without any interpretation on my own).

Please dont even bother responding to my posts because you are trolling, and I dont want to listen to your own interpretations. Like I have said before, you are just random dude to me and I will rather trust Jason Ronald.

Goosen said the SFS hardware is a blended shader for mipmap, thats what it is.

Go read below. Partial loading of mipmaps was tiled resources / PRT, its already done in doom 4 etc and has been around since ps4 / xb1 .


If you can find anything in a link where MS have developed new hardware on silicon to do the well proven virtual textures / PRT (it has lots of names as been around a long time) then we can talk more.

Its mostly a sales pitch from MS and they chuck everything into the pot, it takes time to correctly pick out what MS actually did out of the sales pitch and it does confuse.
Here's a link where a Microsoft engineer specifically says they have texture filters on hardware. So Sampler Feedback Streaming is even better than Sampler Feedback (DX12 Ultimate feature) which on it's own is better than PRT (claimed here and also said by that engineer in the tweet.)

It's not confusing at all, only for people that are trying to deliberately question everything Microsoft is saying really...

Speaking of getting “100gb instant access” wrong...

Dude has this tweet pinned :messenger_tears_of_joy:



I found it interesting how MS barely mentioned SSD and was all about and screaming all days about Teraflops since their console reveal, and since post Cerny presentation they started talking all out about SSD, bottlenecks, data access and cie, hum..

A coincidence maybe, or maybe not so much..

People here question everything what MS engineers say, yet believe Cerny no matter what. SFS is not a new technology according to some, but AMD smartshift is. No one knows how far PS5 GPU will downclock, but people believe it will stay above 10TF no matter what. Some people believe Cerny so much, they even think higher clock 2.2GHz on PS5 will not only close 2TF gap, but also destroy XSX by a large margin.

Yes SFS is a good feature, yes its a hardware filter which is nice because it allows a smaller prefetch or running closer to the wire and its a back up if something arrives late as you dont want GPU stalls.

So say you prefech 10 seconds of gameplay, you can push to 1 second of gameplay and have a back up on XSXto stop a GPU stall, great as both consoles can now have 3rd parties push streaming and detail on both consoles (and PC can look after itself and pop in :messenger_beaming:lol).

PRT / virtual texture software is sort of a different topic, but mixes in with the less streaming pool narrative, all hail Carmak.

I would like to read more about the "form" of PRT being used differently on Nanite voxels and how Nanite does its thing as its different to just normal mipmaps (as there are none). Is nanite using 3 frame update streaming or half a second ....Epic just said streaming pool size so far....

What I do want to know, and I agree with you on that is the performance increase from SFS over PRT. It's not clear now, they said using hardware in Xbox One X they saw that 1/3 of the texture is only being used, but not sure if that's also the case when applying PRT. Then again they are talking about averages so if most games use PRT, than SFS must be another big performance increase on top of it. We'll see.

Never did any reading on the new UE5 features, so no clue about that :)

The 2.5 claim was compared against an Xobox one, hence it is comparing against the old IO system streaming and slow fetching so thats why I have a beef with it, as MS know too well posters will be exagerating and misrepresenting reality it all over forums. Its a bit naughty is my opinion and they throw PRT+ in there just for good measure..

Anywway back on teh subject, SFS is not free, it helps with GPU misses and stalls, but also has a performance cost. I recall there is a slide on this doing the rounds. From DX12 ult :

Performance and Stochastic Update of Feedback Maps
Recall how a feedback map entry represents a mip region of texels in the paired resource, not a single texel. In typical scene rendering, when samples come from closely-spaced-together UV coodinates, the written feedback can be redundant. Redundancy is exacerbated as the mip region size increases.

Given the possibility of wasteful redundancy, it is critical that the operation to update the feedback map does as much coalescing of redundant values as possible before going through with the feedback map write. With this in mind, reducing the sheer quantity of feedback map operations by stochastic methods (e.g., random discard) may be worth pursuing by applications in their shader code.

Remark
Experimental results have shown that discarding over 99% of feedback map updates can still provide enough reliable data to the app. A discard heuristic approach is not proposed as a runtime/compiler feature in this document but would be a possible implementation idea for the app developer.

Series X design can allow MS t o switch approach to refresh a console+ within 2years. 🤷‍♀️

Wait, what? Going by the CU count, MS is likely using older chiplet designs that went beyond 40. Sony, on the other hand, seems to be using the new chiplet design that allows for stacked chiplets (40 / 80), which means that an hipothetical PS5 pro a few years down the road could leverage tech that seems to be there today, making designing it much simpler.

What? How can your PS5 pro be easier to design than MS just unlocking Series X disabled parts??

This, we are talking about a quick refresh Series X+. Probably sold at the same/lower price, probably replaces Series X entirely. Time to market is quicker to attract those who are looking out for new a purchase.

This is why everyone cannot be famous...

Well technically his math is 100% correct - without SFS and compression XBX would need 12-15GB of raw bandwidth to achieve the same results.

Actually if you think about it, they can just replace one of the motherboards, the one that contains APU, RAM and SSD, and they can indeed have a new, beefier console.
