I assume this mimicks the "secret sauce" the next gen consoles will deliver with their (de)compression magic.

Yup should mean you don't need CPU power for decompression anymore... I'm SO looking forward to benchmarks.
Nice Stoll there

I love technological advancement. This one is a big one in terms of storage IO.

Yup PC folks, thats a real advancement in HW. Great news!
People were excited about next gen SSDs not because of SSD addition itself but because the I/O work that implemented around it.

I wondered what the PC way of doing this would be, curious how much performance it takes away from the GPU's regular tasks (although perhaps it doesn't matter as much considering how powerful these cards are).
We probably need a lot more information.
We probably need a lot more information.
Some math:
PC 7GB/sec -> 14GB/sec = 24 Intel cores
Sony 5.5GB/sec-> 22GB/sec = 9 CPU cores
Pretty accurate difference between the skill of Sony and NV software engineers...
Because nvidia ripped them off last time and they don't have a x86 cpu. It would need to be a more expensive separate CPU-GPU. Don't burn bridges as they say and nvidia burned them with Sony and Microsoft.

yeah, I'm getting myself a 3080 for sure with that price.
question. I'm currenting running a i7 (8 core I think) 3.5 GHz CPU and 16GB ram. if I switch to a 3080 from my current 780, would I be able to get the most out of it or would I need to change the CPU/motherboard also?

PS5 is still best in class. Will leave this here.
I'll elaborate a bit. This is just from what I understand.
It's Direct Storage that allows streaming from SSD to GPU memory, we've known this was coming to the PC space for months. See below:
This is what is being done in principle, and this is mentioned in the presentation itself. Furthermore, it seems that decompression is done on the GPU rather than the CPU? At least that's what "GPU lossless decompression" implies.
Easy enough. On the Series X side however 2.4GB/s (Raw), 4.8GB/s (Compressed) was only impressive compared to PC before DirectStorage landed. Now that it has, it's hardly up to par.
PS5 on the other hand is double 4.8GB/s at the bare minimum compressed (9GB/s). In real world performance we know it can peak potentially at 22GB/s. They've future proofed their solution.

Yeah most definitely, go with AMD, they are cheap and powerful, especially now that Zen 3 is closer, Zen2 is getting cheap enough even in high-end.

I demand a list of names and addresses of the people who said ps5>3060, 70, 80, etc, or even the high end 20xx series.
Looking forward to the PS5 regulars now accept the industry is following Microsoft on IO not Sony. That the Microsoft engineers were not liars after all that direct storage was not just PR. So games will be designed around direct storage since the industry is adopting it.

Sony aren't in the business of helping PCs. This isn't a charity. They're adopting Microsoft's solution because Microsoft are in the business of aiding the progress of PC. Nobody said DirectStorage was PR either.

Actually now people can finally acknowledge that SSD and IO performance DO make a difference.

no it's 14 GB/s for probably ~28gb/s using unknown decompression tech cost 24 core. so 500mb/s core
ps5 is 5.5 GB/s requiring 9 core so ~600 mb/s core
ps5 is not 9 cores when kraken bench around here can show you one 3770 can decompress around 1gb/S http://cbloomrants.blogspot.com/2018/02/oodle-260-leviathan-rising.html
note than in this bench zlib is at average 3x worst , so acocunting more powerfull cpu in both case, if nvidia figure use zlib they are in a correct ballpark when sony is in huge bloating territory

No shit considering the API on PC is also DirectX. That's not a revelation. Games on Playstation have never used directX, they have their own. Who said directStorage was just PR? The bullshit about secret sauce velocity architecture offering 3x boost was just PR when MS fanboys were eating that up as "compared to competitors" rather than last gen.

Here's a scenario.
Provided data is compressed extremely well for a PS5 and a PC equipped with a 3080 and a Gen4 SSD. Which reaches the highest peak with decompression?
Well 7GB/s raw actually. 14GB/s decompressed.

Hmm is it pci-express 4.0 only? It wasn't said anywhere in the stream so I'm hoping it will work for all ssds (with various benefits of course) .
But overpaying for that x570 mobo never felt better

i read on abscissa read bandwidth and you ?

If anything it looks like XSX’s IO performance will be what holds back next gen the most.
Now people will accept that the I/O is important
www.neogaf.com
People downplaying PS5 I/O bandwidth fail to realize that 16GB of RAM is a small upgrade from last Gen & the SSD is going to be it's life line
The trips to the SSD is going to be frequent & nothing like before when you load a level into RAM then play the level. Next Gen consoles will be moving data from the SSD on a frame by frame bases. Sony made sure to get a higher bandwidth than what was on the market before PCIe 4.0 so...
The abscissa shows a "decompressed" number under 14GB/sec and not raw.
I.e. it's after decompression.

Not to mention that those 9x AMD cores-like are separated, and main CPU is like 100% free.

Who has said that?
In terms of plain technology, pc will always be the king. Period.
A fixed platform will always deliver though, regardless of the power. If we have seen it in the most underpowered and basic generation ever(current gen) , with some of the best looking games of the gen to be found only there, we will see it even more in the next console generation, which will be more custom/powerful.
They needed to do something like that and all of us we will benefit from it. Multiplatform games will benefit from it a lot IMO, for all platforms. Win-win for both pc and console gamers.

Sony could of worked with amd, intel and nvidia to get their IO the standard. You guys said all the velocity was all pr don't back down now. You guy have 100 pages of trashing it in the official thread. Stand up eat your SSD crow.

No lie, this conference was more entertaining than any conferences centered around gaming this year. Haven't been this excited since I was introduced to hot sauce and WAP.

Note they also mentioned that that there were some similarities in the Raytracing hardware setup to the Xbox.
By doing what, adopting DirectX? The IO 'standard' does not matter that's what the abstraction layer does.
Show me the pages of 'you guys' saying Velocity was all PR. In fact show me anyone who said it's not real. Anyone who was calling it PR was likely related to MS giving it PR names and MS fans saying "but does Sony have that they haven't said they do". Weirdly just as you are doing now by suggesting that Sony doesn't have directStorage. It's a marketing term for a feature that PS5 has and has one of the better performing versions of.

I thought gpu decompression is not new. What's new with nvidia's approach?
So how is the moving around of data handled? PS5 has a DMAC (separate from the decompressor) to handle data flow. How is it handled here?
And also the check-in, how is it handled? I suppose check-ins are processed before it goes to the on-board dedicated storage? So the cpu/gpu doesn't have to deal with it once data is needed?

xsx i/o is fast. The PR is that it's as fast as the one in PS5. Sony has put 6 custom chips in there to deal specifically with I/O while MS only has two. That's why you're hearing devs praise about it.

Oops, apparently the lowest common denominator in 2 years will be the Titan overlord XSX, who would have guessed.
Firstly, these cards are amazing.
Secondly,
What are you trying to prove here? You do realise that XSX now has the slowest IO out of all platforms?

I knew PC hardware would pull ahead fast, but this......Nvidia just buried the consoles from a performance AND pricing standpoint (which I´d never deemed possible).
700$ for 30tf holy hell....
And that I/O promise...+ the DLSS.....suddenly 8k doesn`t seem far off anymore.
Absolutely incredible.

No one said that Sony did not have the baddest solution out there. The question I posed before would the industry follow with all that custom hardware or follow the Microsoft hybrid approach. Would the budget been better served beefing up the apu especially now oodles up the compression making it way more than the apu can process.
Does nvidia magically make any hard drive a fast SSD? As long as the storage is enough to feed the beast that is that is all that matters. Nvidia is feeding a 36tf beast so it needs more data duh. Sony is the one out of wack way more storage io than processing power.

listening to the man you're correct
it puts the core performance at 7000/24 => 291 mo/s
this mean zlib on current cpu would perform a little under 3770 core....yeah it's PR.
sony 9 cores can also work if you use Zlib but no way you need 9 cores if you use kraken too.the comparison stays misleading
for reference zlib is ~650mb/s area on current cpu.
