Yup should mean you don't need CPU power for decompression anymore... I'm SO looking forward to benchmarks.I assume this mimicks the "secret sauce" the next gen consoles will deliver with their (de)compression magic.
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.too bad, why did MS go with AMD for GPu for xbox?
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...
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.

PC 7GB/sec -> 14GB/sec = 24 Intel cores
Sony 5.5GB/sec-> 22GB/sec = 9 CPU cores

Nice Stoll there
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.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?
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.Looking forward to the PC regulars now accepting the importance of IO.

now the console people can stfu
no it's 14 GB/s for probably ~28gb/s using unknown decompression tech cost 24 core. so 500mb/s coreSome math:

Sony 5.5GB/sec-> 22GB/sec = 9 CPU cores

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.Looking forward to the PS5 regulars now accept the industry is following Microsoft on IO not Sony.

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 i both case, if nvidia figure use zlib they are in a correct ballpark when sony is in huge bloating territory
It's 14GB/sec decompressed (7GB/sec compressed)
Read the slide carefully
i read on abscissa read bandwidth and you ?It's 14GB/sec decompressed (7GB/sec compressed)

Who has said that?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.
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 shit considering the API on PC is also DirectX. That's not a revelation.

By doing what, adopting DirectX? The IO 'standard' does not matter that's what the abstraction layer does.Sony could of worked with amd, intel and nvidia to get their IO the standard.

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.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.
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.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?
listening to the man you're correctThe abscissa shows a "decompressed" number under 14GB/sec and not raw.
I.e. it's after decompression.
