I think the PS5 might require less RAM for the OS (as mentioned in the quoted list as system RAM). The SSD of the PS5 would allow it to also stream part of the OS assets (or even state) although I have no clue how hard this would be to implement, if they are actually doing this or how much RAM it would save....
In all fairness, the xbx ssd should be ample enough to quickly swap o/s GUI assets too even if not as snappy as PS4. I'm firm in belief the biggest reservation is for gamedvr video without much alternative unless the platforms force usb storage for dvr functionality.
PS5 and XSX use different OS so it's impossible to guess which one uses more RAM. 2.4GB/s SSD is a total overkill for an OS and apps like Netflix, so I'm not sure PS5's super-fast SSD will actually help it to save OS RAM usage. On both launching an app and dumping/reading its' memory state will be virtually instantaneous. I mean, how long will it take to read an app like Netflix which has ~200MB memory footprint on a 2.4GB/s SSD? 0.1 seconds? 0.2 seconds? Both machines can easily leave an extremely small memory pool for apps. So what matters is the actual OS footprint in memory, which we have no idea what it will be. It could be anything, 1.5GB, 3GB, anything is possible.
So basically the way I see it is that currently the fixed pool of RAM contains assets that are so often used throughout a section/level that it's smarter to keep them in RAM continuously. That's what I'm calling the fixed pool. Imagine models/textures for a player model in a 3rd person game. Those assets will always be used so there is not benefit in streaming these.
No I don't believe so. The PS5 solution probably improves cache latency and efficiency for all assets.
You can't really 100% separate the two. Right now both the data for this very frame, the data for things 90 degrees to the camera, and data 30 seconds walking distance are kept in RAM. So basically the whole room around you is in RAM and probably a few more rooms around you "just in case". The new SSD approach by MS and Sony is that don't just forget about keeping the adjacent rooms in memory, but forget about things that are 3 centimeters out the frame. All of these will stream into a "next frame buffer" which the next frame will use. It means that almost all VRAM data can be data needed for the currently rendered frame. So looking at it as the PS4 memory usage minus 99% of the streaming pool isn't really correct, it's a full paradagim shift in the way VRAM is used. The fixed pool won't become smaller, it will actually become huge, but it will be extremely efficient because the fixed pool data won't contain textures that are behind you, it will mostly be exactly the things you see in the current frame.
It could be, or it could have less available memory for games. Both options are valid, we will have to wait and see but I see no reason assuming PS5 will have more RAM available. When I make assumptions right now, in order to be fair, I assume both will have 13.5GB because we don't know yet which has the advantage here. 2.5GB memory footprint for an OS + running apps is pretty low in 2020 so expecting the PS5's to be 1GB is a pipedream IMO. If PS5 had anything lower than 2GB OS footprint, Cerny would have yelled it from the rooftop in his talk. But I guess we will have to wait and see how big/small the PS5's OS footprint will be.
Think of the PS5's coherency engine and scrubbers as a way to make PS5's GPU eat up less memory bandwidth while SFS is there to make a more finely grained requests from the SSD. If you turn the camera and there is an oil painting on the wall that 1/4 of it comes into frame, SFS will help the GPU ask just for 1/4 of the oil painting texture instead of the whole texture. It's part of Microsoft's plan to stream from the SSD to the next frame, only the exact specific new data that will display on-screen the next frame will be requested so it will need to transfer fewer data per frame from the SSD to achieve the same results.
I still don't think you understood my post. Please read my post again and please see how I have defined the fixed/streaming pool. I think if you follow my definitions you see that you basically agree with my post.
My bet is on Horizon 2 for Sony as their main next-gen showstopper, especially with a flying segment. MS are probably going with Halo and I hope they innovate through gameplay. A flashy but standard run-and-shoot fps demo is gonna feel stale imo.
No, SFS is a software API that can be done on any system while coherency engines and GPU scrubbers are hardware blocks / silicon only available on PS5.
SFS is hardware in the GPU that supports Sampler feedback. It's not a software API.

As far as I understand, SFS is the MS implementation of a system based on AMD hardware. For all we know the PS5 uses the same hardware with their own implementation. But of course so far we have no info on that so let's assume they don't use it.
Sincerely. Master Chief throwing a plasma grenade at the face of an Elite would be all I need.
It was a strawman, dont worry too much. He just wanted to bait you.
Too much money and attraction flair in Halo and Horizon to not pursue sequels. That's the boring part about established IPs, devs would rather take the safe route and make Our Beloved Franchise 8 instead of creating new, really creative and exciting stuff.
Just more of the same can be "ok" for another go, I guess. But I think it's important that we speak up when old IPs keep churning the same old formulas without innovating.
If your streaming pool is 1 frame size, it doesn't matter if the SSD is 2GB/s, 4GB/s, or 15GB/s, the streaming pool will still be 1 frame size which is the smallest it can possibly be. If you are using the faster SSD to stream higher-quality assets, it means that:
Nah man, not everyone.We're sure that the PS5 doesn't have separate OS RAM, like the PS4 Pro? I suppose Sony would've mentioned that by now, though?
I think it's fair to say that every PS fan is currently hot for Aloy right now
Hasn't the Zen chipset been better with game dvr/streaming without much bother compared to the jaguar?

That's because the Cerny speech wasn't aimed at developers, it was aimed at tech websites. Developers knew this info a long time ago and the talk was very superficial for the developer level. It was clearly aimed at us, and places like Tom's hardware or DF, in order to create hype. Why do you think it had 14M views? Yeah, it's more hardcore than an E3 presentation, but the only developers who learned something new about the PS5 from this talk were probably the ones developing exclusively to Microsoft
I think Daniel Ahmed talked about ~50$ over the console BOM. So it's something like BOM + 50$.
Two Reasons A $400 Xbox Series X May Be Possible: A Pandemic And Revenge
The idea the Xbox Series X could cost $400 seems wrong on its face, but these are strange times, and Microsoft may be plotting something.
