NVIDIA RTX IO

That's awesome, thanks!

 

Might need a faster PCI-E 4 M.2 SSD for it to shine though, which also means a board and CPU that adds the support.

 

Good luck on that one with the intel 11th gen so many bad reviews on youtube

I went for the 10th gen i9 10900K on a tuf Z590 Mobo personaly

 

Nah, AMD like the consoles.

 

The consoles with PCI-E 3.0 4x SSD inside? :O
By the way, judging by nV's wording, I think "RTX IO" (I use this term here deliberately) was designed with PCI-E 3.0 16x SSD in mind. (That's why they said "even faster than Gen4 [4x] NVMe", thus >8x 3.0.)

 

What are you talking about? Both the PS5 as the Xbox Series X got faster drives.
With raw data we have what, around 3 drives for PC that perform up there which all are PCI-E 4.0?

 

Ah, sorry. I remembered wrong. I see the PS5 has a Gen 4 internal NVMe drive. I thought those consoles had Gen 3 NVMe.

 

I wonder what kind of performance improvement should be expected. Even modern games don't stress so much the hardware when loading assets from an ssd, if not for the games that still have a waitscreen and preload everything at once and may reduce that waitscreen time.
Most modern games, like CP2077, don't stream more than 30-60MB/s from an ssd during normal gameplay or car racing, and a single core can easily decompress that bandwidth without much effort.
Maybe further ahead we will see newer games that will take advantage of this feature by design in every area of the game, but it would take a while for 3d engines to be rewritten to really exploit the tech.

 

Didn't RAGE rely heavily on texture streaming? I think Carmack called it Mage Texture(ing) or something. Did ID mostly drop the concept or is it just that current PCs can easily serve the needs of later ID games like DOOM (2016)?

 

PCI-E 4.0 I have on my mobo but that works exclusively with 11th gen intel in this casy. I don't care it is always the same they want to earn more money out of you for better tech getting to old for that ......

 

The new drives found in the consoles manage 4.8-9GB/s compressed data, when decompressed you can half that, which still is quite a lot for real time processing and loading.
That uncompressed data can be fed straight to the GPU for rendering, imagine being able to start a game without having any loading screens.
There is a bit more to it, like instant searches, improved streaming speed, very fast boot times..
As for game seeing games taking advantage of it, that can already be seen with the PS5 and even the Series X with the slower drive.

 

There are plenty of games with huge open worlds which rely on on-demand texture streaming, most noticeable @high resolutions and ultra settings when comparing them on HDD vs SSD.

 

To support DirectStorage for Windows, they are overhauling the Windows I/O Manager stack to make it batch-process multiple I/O request packets (IRPs), and probably replacing the StorPort / StorNVMe driver model as well.
How the API surface would actually look on Windows, and whether Nvidia's RTX I/O is in any way related to DirectStorage, is not really known yet.

See the GameStack Live session video and slides:

I really hope that SSD's and Gen 3 NVMe's are included. Maybe not SSD's with their 550mb/s read/writes but a gen 3 drive like my Corsair MP400 4tb and it's ok speed. I mean it's 3.5GB/s or 3,480MB/s read and 3000MB/s write. I'll be gutted if they only support PCIe 4.0 drives.

I/O throughput on new Xbox is only 2.4GB/s but with this tech that is doubled to 4.8GB/s using compression/decompression but i'm guessing it's a Gen3 drive or am i wrong? I can't see proper specs for the 1tb version so i don't know.

 

Thanks for the links, very excited for this tech to make it into Windows.

 

I'm pretty sure that it's been confirmed already that any NVMe SSD will be supported. SATA devices won't be.

XS SSD is NVMe PCIE4 but the drive itself isn't saturating the full bandwidth of PCIE4 connection.

 

Well i hope it is sooner than later because i've read about 2-3 games i will be buying in the near future. System specs for some of these future games has 150gb in needed storage size. I know ridiculous right...

 

I don't see this benefitting PC gaming much as most users have the OS on an NVMe and then game library on a second larger SATA/HDD, not many will have also a large NVMe secondary drive.

 

A fast NVMe SSD being minimum requirement for gaming is inevitable in the coming years. So either get a bigger OS drive to which you'll be able to move games which you play or get a second NVMe SSD for game library.

 

Oh, I fully understand, I am just saying the mass user won't be at min spec for it. Sure guys here are now but that is not the norm.
We still have to see a performance improvement.
