This Thread is about Nvidia RTX IO which recently has been introduced.

- Do you think it will have a noticeable increase of performance?

- Will this technology only work with PCIe 4.0 CPU's? If yes thats good news for AMD users and bad news for Intel users.

Yes, but I bet we won't see any games making use of it until around 2021, and the major difference will be in loading times, there won't be any fps boost.

No, PCIe P2P DMA works with version 3.0 too, but with PCIe 4.0 (and a 4.0 capable nvme) you will have higher bandwidth.

Could help lower CPU's need on memory bandwidth, so it should help those running slow memory

I dont see why in theory

i rewatched the RTX IO part of the presentation about 5 -10 times, yet i still havent quite understood what it means, i know it speeds up loading times, but what else have they spoken about it?

The old way of filling up video memory with stuff the card needs is from storage to RAM, then RAM to graphics card. With RTX IO, card fetches data directly from storage without going through RAM.

Without having the >CPU< loaded to decode many more Gigs of data to populate the Vram.

 

The CPU isnt in this equation, NVIO skips the CPU decoding as it always happens, and thats done via the GPU now. So populating VRAM (Loading screens with an Overlay to see VRAM) would be MUCH faster without the CPU Subsystem bottlenecks (3+ GB/second)

I fully expect Cyberpunk 2077 to use it, since it's using something similar on all other platforms already.

DirectStorage isn't readily available yet, developer preview will only land next year according to MS, expect actual games making proper use of it only by the end of 2021.

I have a question on the topic. I searched for the answer in various places, but could not find any conclusive info.

 

What is really required for RTX IO?

I will ask with an example:

I am building rig for my friend. He gave me a budget. I wanted to go with 3070 graphics, amd 5600x cpu and x570 MB. This ended up being a little bit over budget, so I though of going with B550 MB instead.

 

And here is my question - will RTX IO work?

B550 uses PCIE 3.0 for chipset lanes, but You have PCIE 4.0 from CPU. Since this tech was designed to bypass CPU, I assume it uses chipset lanes exclusively? And then, i think it might require x570 chipset? I guess I just want to know if I can shave some of the price there, or should look elsewhere.

I hope MSFS will make use of this tech, as the loading times in flight sims have always been on the longer side lol

It will work on any PCIe generation just fine. All it does is reduce load times. It basically allows the GPU to directly request data from the SSD, so it doesn't have to be processed in any software, or by the CPU.

You are asking about a technology that is not even being shared with developers for another year. Nobody knows for sure yet.

Keep in mind that what you are asking about is MS DirectStorage, not RTX IO. RTX IO is simply meant as a way to decompress data on the GPU instead of using the CPU.

 

DirectStorage is the API on top of P2P DMA that allows the GPU to talk to the NVMe directly. And yes, it should work in theory, but we will only know for sure once it's available (which may take a year or two).

[kubadro]

Ok, thanks for the clarification. Sortof.

I was really under the impression that PCIE 4.0 was a hard requirement for DirectStorage (thanks igor, that is what I actualy meant, I just confused techs). And i see here that maybe it will be, maybe not. Hope it will not
