""According to Oodle, the previous 8-9GB/s IO bandwidth figure was provided by Sony by multiplying the 5.5GB/s peak bandwidth of the PS5 SSD for the standard compression ratio of 1.45/1 or 1.64/1. However, when factoring in both Oodle Kraken and Oodle Texture, the developers of the technology have seen an impressive compression ratio of 3.16/1 for a texture set in a recent game; this would translate into an IO bandwidth peak of 17.38GB/s, as mentioned in the headline. ""Oodle Texture is a software library that game developers use at content creation time to compile their source art into GPU-ready BC1-7 formats. All games use GPU texture encoders, but previous encoders did not optimize the compiled textures for compression like Oodle Texture does. Not all games at launch of PS5 will be using Oodle Texture as it's a very new technology, but we expect it to be in the majority of PS5 games in the future. Because of this we expect the average compression ratio and therefore the effective IO speed to be even better than previously estimated.
Kraken is a powerful generic compressor that can find good compression on data with repeated patterns or structure. Some types of data are scrambled in such a way that the compressability is hard for Kraken to find unless that data is prepared in the right way to put it in a usable form. An important case of this for games is in GPU textures.

I dont know any more than you guys do, but remember that post from a dev I posted a few months ago? The same person told me that more often than not 20GB/s will be achievable on PS5. It's not something out of reach for the console.
Sony keeps announcing ssd info but eerily quiet about RDNA 2 features
Why does it require GPU cycles for? PS5 has dedicated hardware for complete IO including Kracken decompression etc. Oodle is made by the same company RadTools.Doesn't this require GPU cycles to use? Anything beyond the builtin compression will consume additional resources. Technically XSX can use this too.
here you go:
he says PS5 SSD speed isn't theoretical like PC SSD's.
This article is from RadTools employee and not Sony you tool.Doesn't matter, none of that is sustained speed and they're advertising peak speeds just like snake oil vendors of SSD's do.
You know the Firecuda 520? Arguably one of the best drives on the market at $250. Well its advertised speeds are up to 5,000/4,400 MB/s.
Guess what its sustained speeds are? PCI-E gen 3 @ 1.7 GB/s, PCI-E gen 4 @ 2.1 GB/s. Sony is bullshitting everyone with peaks and not mentioning a word of their sustained speeds.
I'm guessing they have some freon encased around the SSD, to negate the laws of physics. They must have the best cooling solution on earth to sustain those speeds, as they will require more wattage, which produces more heat, which slows down even the fastest SSD's with large heatsinks, which might not even fit in the ps5 to begin with. I'm really curious if Sony will address this in a teardown soon?
People should look at the market and learn to read, instead of assuming all SSD's compatible with ps5 will have 12 chips/lanes. That's why I mentioned heatsinks, and the possibility of not fitting when it comes to upgrading storage.They actually use slower chips but have 12 of them behind 12 lanes so it is not as hot as you think
People should watch the old presentation instead of assuming it is comparable to PC parts..

A form of it is already being used in current gen games, ps4/ps5 crossgen games, and future ps5 games when they stop making them crossgen.oodle poodle. show me how this enhances graphics in a video game. so far, ive not seen a single game using this shit.
ssd and io sounds like the next blast processing.

Find me one quote on the entirety of the internet of Sony mentioning sustained speeds, it doesn't exist. They're baiting people with peaks.
Heat will affect EVERY SSD, no matter console, pc, laptop, etc. To think otherwise is very foolish and naive. Then again we have no confirmation of sustained speeds on ps5, no teardown, or anything for that matter besides patents. And we know patents don't mean shit unless they are implemented and utilized in real life products.Obvious bullshit.
Sony has a shitload of patents on how they do their SSD arch.
But you need to research why peak != sustained in PC SSDs first.
Missed opportunity to call it "Noodle Kraken"

PS5 has a dedicated kraken decompressor that maxes out at 22GB/s, so the CPU doesn't have to lift a finger, however all other consoles that will use this algo. will need to use CPU/GPU cycles for decompression.Doesn't this require GPU cycles to use? Anything beyond the builtin compression will consume additional resources. Technically XSX can use this too.
You're really hung up on that VRS (Variable Rate Shading).
VRS provides about 10% to 15% performance gain by lowering the quality of textures at further distance. That's right, lower quality. It's not all positive, when it comes to that feature.
It's a standard feature of RDNA2, so the PS5 most likely has it, but Sony for what ever reason didn't think it was worth mentioning, but other features were more worth mentioning like the geometry engine, which at a technical level is far more performant in making a difference.
AMD mentions it in the same sentence with Ray tracing, and yet, not too long ago, people were claiming that the PS5 did not have ray tracing hardware (since they claimed it was RDNA 1 or RDNA 1.5).

Very impressive.... PS5 looks to be a speed demon
https://wccftech.com/ps5-io-system-...oodle-texture-bandwidth-goes-up-to-17-38gb-s/
Of course, that may not be typical, and not all PS5 games will necessarily take advantage of this technology to the fullest.
you should expect 1st party Sony to take advantage of itThis is software based compression, nothing new

It's new. Currently Kraken can't really stream BC1-7 textures efficiently as it cant find compressable patterns. With the new software texture compressor the textures are compressed in such a way that Kraken can now find the new kind of compressable pattens (invisible to the eye) in the textures for much better streaming rates.This is software based compression, nothing new
Depends, what's the cpu performance hit?
This would be exciting to see without cross Gen games holding it back.
Layman terms for an idiot like me?
What does this mean for games like GOW Ragnarok assuming it's PS5 only (please no cross gen please) aside from really fast load times?
How do you think this will affect gameplay or gameplay dynamics?Better textures, possibly more detailed models, less pop-in.

I'm most interested in how this will elevate gameplay for next gen
I'm sure Santa Monica wants to make their game feel more movie like if that makes sense
Like an interactive movie with advanced animation, destruction, AI, etc.
I'm interested in seeing technical leaps in gameplay instead of just pretty graphics alone
Ratchet and Clank at least make an attempt at this but I feel it can be expanded upon more
As others have said really negligible hit, I would think you can consider it free unless you compress even further with BC7Prep and need to undo this step alone on the GPU.
