Sure, you can require more main RAM and do a giant initial load to fill it up enough to deal with the lower disk bandwidth… and? The point of the work MS and Sony did was to be able to have less than 16 GB of RAM dedicated to the games total. This has been discussed plenty of times already, I do not think splitting hairs about this is necessary IMHO.
My point was that SSD's and I/O of the PS5 wasn't needed for PC because of RAM.
Its still useful tho and a improvement at the end of the day, but absolutely not needed to get things to run on what the PS5 is doing.
It's all handled bij the I/O complex, something pc's doesn't have to offload all that to the custom controller without having the CPU constantly running for decompression or ram being used heavenly. It is all handled by the I/O complex to ensure that data can be extracted constantly and ram usage remains low.
Are you seriously going to tell me that a simple PC with DDR4 3200MB/s does that scene a little better than the PS5? Btw, what do you want to prove with that gif? that you can use the editor camera speed over a empty area with some rock assets?
I think I was very clear with what I meant, and that was this:
This part showed the SSD combined with the I/O. As far as i know, we have no comparison so at this point this demo runs only on PS5 (the full gameplay demo and not just a editor breakdown with a lot of stuff disabled). And it was not even final devkit back then...
Why is this necessary if, in your opinion, it would all work well? So why do we need RTXI/O? No if I read your post, it's another PC fanatic who can't have it that the PS5 has a chip that takes care of features the PC just can't do quickly at the moment, without taxing the CPU for it or Or fill up the memory completely.
And if you want to know, I game on both PC and console and I was able to run the UE5 editor myself. In editor all gameplay features are not enabled so also no heavier. If you throw a lot of assets in the editor, you can make it as heavy as you want.

- CPU compression will never be done on the CPU at 3+gbps ( lower also ), its either gpu or no compression. So talking about loaded the CPU up to the brim is useless as it will never happen. RTX I/O solutions will take this into account whenever it released other then that compression won't be a thing at higher speeds simple as that.
- Ram can be used heavily that's why ram is there.
- Jup it lowers ram requirements, which is also useful for PC that's why we see movements towards it by nvidia and microsoft its not needed however,.

I am saying DDR is a fuck ton more faster then SSD's this is why PC has Ram and consoles would have had Ram if it wasn't for there constrains. Ignoring ram entirely like u did and move straight to PS5 architecture without considering how PC work but still judge them is ignorant and i corrected that.
The picture showcases speed u can move through a scene once it sits in ram.
I will tell you something funny, u think the PS5 demo at the end is impressive, i will tell you they could have speeded it up far faster. Because all the data is already in the ram. the low requirements on PC suggests this. They just choose to keep it at that speed, i am pretty sure there is even a demo from sony in some game where they slam through a city at rocket speed. I could be wrong about that tho can't remember anymore.
They where probably limited elsewhere or just made the choice that it was enough and limited it there. we don't know because no data.
Ram shits all over SSD's, this is why u still got a 16gb pool of ram in the PS5. And they would have gone for more if the APU allowed them most likely.

So can u show me the numbers what exactly was loaded into the ram and when? they did bother to showcase you polygons right? so why not just showcase what the SSD was doing and the i/o solution u talk about? In a demo completely focused on that aspect? interesting demonstration right?
The demo there had 6gb of v-ram usage, deload and reloading that in while having stuff on the screen would take 1-2 seconds. That SSD is 100% doing jack shit for 99% of that part. Welcome to the world of ram as everything has to sit in it. not even system ram could be used as its way to slow to load data in on the fly in that scene to be pushed out by the gpu/cpu at time. it needs to sit in the v-ram and it does exactly that.
Unless they where streaming a video from the SSD at a bittrate that requires 5,5gbps.

Because its a improvement all around. There is no reason to not move towards it.

I just explain you how the world works in reality and not in some fairy tale bullshit world. if you disagree with any point i make come with arguments instead of idiotic cursing against a wall. U sound pathethic.
CPU taxing and memory taxing i already covered.
And if you want to know, I game on both PC and console and I was able to run the UE5 editor myself. In editor all gameplay features are not enabled so also no heavier. If you throw a lot of assets in the editor, you can make it as heavy as you want.
Good for you, i have consoles and i have PC's also. ( well consoles handhelds switch, have ps1/ps2/n64 so there's that. And honestly if you wonder about tech always good to dig deeper into it. However keep a open mind and stop shouting stuff like "pc fantastic". Its just a plastic box, same for computers.
So how expensive do you think a console with 32gb ram gonna cost? Or with a Nvidia GPU? I think you've split yourself from reality with this PC is better at everything nonsense because you can buy a part that costs more than the PS5 alone. Bravo with this logic. Looks like little PC warriors are upset. Reminds me of when Linus went out of his way to find an SSD that was faster than the PS5's. Except it cost a few grand and only about 0.01% PC owners would have it. Bravo!
The PC couldn't stream in the data quick enough if it had total 16gb ram for whole system. It has to load everything into ram first.
Now why didn't Epic simply run the demo with a PC with 16gb ram total and a NVME drive both at the same time with a PS5?
Where did i say consoles need 32gb of memory. I said they could drop the SSD performance ( keep the i/o ) and invest into a nvidia GPU so we don't have games like control at below low settings performance and every game will have RT in it without effort. There are reasons why i say something.
All console games will be limited if they do move over however to new solutions towards xbox outputs, which means 5,5gbps will never be used other then for first party games ( well improved loading times probably ). But lets be honest there first party games will build games no matter what for the box so they are hardly relevant in this matter.
the demo was made for the PS5 not PC. PC has its own demo which is not on the PS5 because it was not made for it.
Everything else is just dumb rambling with no actual argument other then "i don't like things u say" zero interest in starting a piss contest.
PC DDR4 vs PS5 SSD? What kind of comparison is that?
PS5 also has system RAM (& VRAM) in a single pool. Where do you think the assets go from its SSD for the CPU and GPU to access?
Where did i say the PS5 didn't had v-ram exactly? I just state PC has Ram that helps problems like this out at higher overheads.
