Definite game changer, combine with VRS, Mesh Shading and DirectML Super Resolution and you have a monster machine because these hardware based optimizations decrease the memory usage, prevents I/O bottlenecks and free resources on both the GPU and CPU, the reason why the Xbox XSX should be able to do real time real tracing on 60fps when all the optimizations are used smartly. Looking forward to the first mind blowing exclusives

Agreed. While the underlying features can automatically provide a lot of benefit out of the box, some features like SFS will require special integration (and better tooling... I'm looking at you, MS!) Thanks for watching.
Sampler Feedback is a hardware feature of all DX12U capable GPUs, it debuted on Nvidia's Turing architecture (along with the other DX12U features) and is also exposed via OpenGL and Vulkan extensions. SFS is a particular software technique built on top of this feature which the Series consoles further optimise with a specific bilinear texture filtering method. It's also worth noting that UE4/5 supports a full software implementation of the tile base streaming encapsulated by SFS, so the benefits aren't entirely unique to newer hardware or the Series consoles.

It's a great video, but they left the most important part out. The thing that Series does that no other GPU can is understanding tiled mip levels. All modern GPUs can load a complete mip level on the fly, but only the Series can ask to load a few squares in one corner of a mip level. Leaving 2/3rds of the texture data that is untouched sitting on the drive.
True, I purposefully didn't dig down into a lot of lower-level details, but kept the explanations general, more about the synergistic aspects of the Architecture as a whole. I left those bits unspoken when showing the mip-map tiles highlighted in the SFS section. It's always a hard call to go too low or too "general interest". Thanks for watching.
Love the video, all of this is going to depend on Microsoft SDK and how easy it is for developers to access and use these features.. If it’s not easy, developers will just use raw system power. So I will be interested to see what developers outside of Microsoft use this feature set.
Absolute truth there, my friend. Until the tools (dev, instrumentation, build, test, etc.) are more mature, we'll have the 80% solution. I'm certain they'll do it though. The end goal of a unified PC/Xbox framework makes sense... but when?
@@StellarContinuumGaming exactly. This is why we were seeing the PS5 pull ahead with system power right now. Because of their higher clocks.

New tech generally does sound game changing. Now we need to see how it will be utilized. MS needs to put out a game built from the ground up to take advantage of VA. Kind like Sony made Astros playroom specifically to show off the dual sense.
@@Rooster832 I hear you but its been a few years and dx12 has only made a minor impact. I just think they would be better served to release the features with a product that shows it off. Instead of talking about how great it is and waiting for a 3rd party to blow our minds with it. Imagine a 4k 60fps halo with path raytracing that had no loading with ms touting its only possible because of VA. As far as gaming is concerned MS does a lot of talk but very little showing. They need to fix that.
It would all be a game changer if devs knew how to utilize it. Through no fault of their own I'd like to add. Devs need more time with the SX creation software. The SX is without any doubt the most more console to date.
Great stuff. The Xbox Series consoles are really a very good machines but we need games coded exclusively for these machines to really take advantage of all these techs IMO!
I'm just a simple man who doesn't not know too much about technological side of things. On intuitive level this technology sounds great for me, but practically speaking i want to buy xsx or ps5 and have troubles choosing between them. I like xbox's design and philosophy a lot, but ps have exclusives and seems to deliver more stable 60 fps (according to digital foundry and other reviewers) while xbox gets slightly higher resolution. While i use 1080p monitor and value smoothness more than graphic i wanted to ask what are the reasons for such result? As a technical expert, can you explain the reasoning behind such ps5 advantage and whether it should be changed in the nearest future? For example I've heard somewhere than ps5 has similar architecture compered to last generation models and it is easier for developers to work with it right now + xbox sent development kits later because Microsoft waited to implement a better chip in their console. So what are your opinion and prognoses for these two? Is it the situation where xsx has a better components and should definitely outperform ps5 in a few months (or at least pair with it in fps stability) or the subject has many unpredictability and prognoses about consoles future are speculations? PS. not trying to fanboy any console, just looking for some competent opinions in the internet:) Would be grateful for complex answer if possible, thanks!
Thanks for taking the time to write Данило Побережний. Also thanks for putting a Lynyrd Skynyrd song in my head. :) While I think either console is more than enough to make nearly anyone happy, I'll try to address your concerns in an impartial manner: 1. Smoothness - Yes, it's true that XSX gets higher resolutions right out of the gate and it's well documented that the XDK/GDK migration hasn't been as quick as one would hope. While the PS5 inherited much from the PS4, the XSX is a more radical departure from the XB1. In early, less optimized titles, this won't show. Digital Foundry pointed it out too. In some cases PS5 did have smoother framerates, but we're seeing those fixed slowly but surely (ref Valhalla 1.04). In the long-term, I expect XSX to hold an overall advantage similar to Xbox One X over PS4 Pro. Nothing huge, but consistent. 2. Exclusives - Microsoft got smoked in the last generation on this. Their studio purchases (now incl. Bethesda) will guarantee a wide selection of exclusives on PC/Xbox (especially with Game Pass Ultimate). Now, I suspect that not all of the Bethesda titles will be exclusive. I can't guarantee it, but think the larger titles might have timed exclusivity (Starfield, ES6, etc.), but as a business, it would be insane to not milk them a la Skyrim. In summary, as in past generations, I'll have and enjoy both. I straddled the Amiga/Atari ST line and the TRS-80 Mod I/Coco lines. I'll do so with consoles too - appreciating the potential and beauty of all of their designs.
Love your Videos, But I wanted to mention Sampler Feedback is a software feature, while on the other hand SFS is implemented on a hardware level. SF is a part of SFS. These posts are from James Stanard, Graphics Optimization R&D and Engine Architect @ Microsoft. James Stanard on Twitter: "@Remij010 @XcloudTimdog @AzureGamingHD We have custom texture filters that I already mentioned. These are in hardware." / Twitter James Stanard on Twitter: "@AzureGamingHD Sampler Feedback is one part of SFS.

Yep. Hardware facilitates the SFS for sure, but tried to keep the enhancements and the effective feature sets on different levels for clarity's sake. To some extent, everything is in hardware, but it's a valid point I wavered on a bit and tried to err on simplicity's side. Good point though.
Be great to understand how volocity and full rdna2 will effect games using these features as guess these are still some way out and no one is talking about what this could mean for games.
This will allow games to have a more dense and dynamic world with more variety. For example, NPCs can have more variety in their outfits, reactions, animations, etc. Buildings can also have more variety in their design. More variety in cars on the street. Better lighting and audio in games. Greatly reduced loading times. Having the scenery in the game change quickly. A lot of this comes from the fact that the new consoles can load data much more quickly. The faster GPU will allow for denser worlds. This means more things can be rendered/drawn in the field of view or with a higher level of detail. Other than the SSD, the CPU upgrade was huge in the next gen consoles. This is responsible for so many things. If AI upscaling is introduced, and performs similar to DLSS 2.0, that will be another boost to performance that can be used to increase framerates or detail in the world. Each gen games would look better but run at 30fps. This time games look better and run at 60fps, and some even reaching 120fps. That's all happening before the devs fully make use of the features of the consoles.
it's not really similar..because they don't have mesh shading...they don't have directml ( not sure about this one ). and no its not really similar...ps5 "velocity system" is called oodle and it's pretty all in the ssd performance while xbox is using clearly much more feature with velocity system.
The PS5 sports a faster SSD and comparable hardware based decompression, yielding roughly double the bandwidth. Beyond that its IO complex accelerates significantly more aspects of file IO than the Velocity Architecture. It has dedicated co-processors that manage memory allocation, calculating the location of requested data within compressed files and GPU cache coherency. On Series consoles these aspects must be handled on the main CPU by either the host application or the DirectStorage API. It's unknown at present whether there is hardware support of Sampler Feedback on the PS5's GPU, which would allow for the implementation of something very similar to SFS. Even if there isn't, UE4/5 supports similar tile based virtual texturing entirely in software which can provide much the same benefit though perhaps not as optimally.
The PS5 can't duplicate the Velocity Architecture. One thing not mentioned in the video is that each of the MIP levels of these textures are also tiled. Broken down into sub-squares that the Velocity system is able to load individually.This is a special texture file type that only the Series GPUs understand currently.
Interesting. what do you think when we will see the game uses this technology from 3rd party dev? Because its very convenient tool for multi-platform games
The transition has begun. Newer games will gradually utilize more features. Big games that are built from the ground up takes 3+ years of dev time. So starting around Fall 2022 for both consoles.
I think its a big deal, even though it works opposite to what UE5 is doing with Nanite. Nanite makes development time more efficient. SFS makes utilization of the hardware resources more efficient. Going over everything. You have the SSD that makes data access faster. DirectStorage that further improves the efficiency of accessing that data from storage. A dedicated decompression block to take the load off the CPU. A higher bandwidth for memory accessed by the GPU, and SFS to reduce the amount of GPU data that needs to be read. On top of that there's an 8 core CPU with two threads per core. Outside of that there's a dedicated block for AI processing and the GPU has 52 CUs for parallel processing. Additionally, factor in the use of mesh shaders. The GPU is a nice upgrade from the one in the One X, but everything else is a huge upgrade. The Series S|X and PS5 have a lot of gas in the tank. This gen is going to be exciting.
Ill be excited when we get games that actually utilize this tech. Its hard to be excited with no games.. Not only that Sony is currently handing it to Xbox Series X on the performance as well in 3rd party titles..
@@StellarContinuumGaming Instrumentation, profiling and build tools seemed to be broadly comparable last generation between the Xbox and PlayStation ecosystem. Do you have insight into why there seems to be such a gap in this new console generation?
@@jamesfmackenzie From everything I've seen and read, the PS5 uses an improved, but largely similar architecture (sliding power allocation, etc, notwithstanding) while Series' VA stack was sufficiently different that while at a high level tooling is fine and familiar, but VA-specific feature tools/instrumentation aren't nearly as mature yet. Again, going by what I read and hear from peers. I'm always interested to learn more if you can provide some insight. :)
From what we know, going from the XDK to the GDK wasn't as smooth as it was on the Playstation side. The XDK was also updated to allow for Series S|X targets, so some games are still being built using the XDK. Another thing to know is that the GPU of the PS5 has less CUs (36) than the one on the Series X (52), but has a higher clock speed. The GPU in the PS5 have the same number of CUs as the one in the PS4 Pro. Games and game engines that are already optimized for this will get a nice boost. The higher the framerate, the greater the impact of small performance differences. So it comes down to how much optimization can be done. Its harder to utilize 52 CUs vs 36 CUs.
@@TheFirstRealChewy Thanks for the info. Definitely makes sense that it’s harder to “fill” and get maximum utilisation from 52 pipes vs 36 - especially if engines from last gen are optimised towards the lower number. Interested to see how this pans out as tools improve
Well, fortunately most engines have backend support that have been (and will continue to be) adapted to support these in a general way. But nothing will ever match hand-tweaked.
@@danielallen7384 yes, it was made specifically for PS5. Almost all of the developers will keep in mind that the game must be ready to run multiplat so obviously they will chose MS tools. This is going to be the factor this generation.

Just a matter of time, sx hasn't even scratched the surface.
@@Rooster832 I hear you but its been a few years and dx12 has only made a minor impact. I just think they would be better served to release the features with a product that shows it off. Instead of talking about how great it is and waiting for a 3rd party to blow our minds with it.
Imagine a 4k 60fps halo with path raytracing that had no loading with ms touting its only possible because of VA. As far as gaming is concerned MS does a lot of talk but very little showing. They need to fix that.
@@billygrant9147 I belive will will see it sooner than later.
It would all be a game changer if devs knew how to utilize it. Through no fault of their own I'd like to add. Devs need more time with the SX creation software. The SX is without any doubt the most more console to date.
Does the series s have velocity architecture
Great stuff. The Xbox Series consoles are really a very good machines but we need games coded exclusively for these machines to really take advantage of all these techs IMO!
Definitely' Luv my Xbox Series 💪 X
Amazing
I'm just a simple man who doesn't not know too much about technological side of things. On intuitive level this technology sounds great for me, but practically speaking i want to buy xsx or ps5 and have troubles choosing between them. I like xbox's design and philosophy a lot, but ps have exclusives and seems to deliver more stable 60 fps (according to digital foundry and other reviewers) while xbox gets slightly higher resolution. While i use 1080p monitor and value smoothness more than graphic i wanted to ask what are the reasons for such result? As a technical expert, can you explain the reasoning behind such ps5 advantage and whether it should be changed in the nearest future? For example I've heard somewhere than ps5 has similar architecture compered to last generation models and it is easier for developers to work with it right now + xbox sent development kits later because Microsoft waited to implement a better chip in their console. So what are your opinion and prognoses for these two? Is it the situation where xsx has a better components and should definitely outperform ps5 in a few months (or at least pair with it in fps stability) or the subject has many unpredictability and prognoses about consoles future are speculations?
PS. not trying to fanboy any console, just looking for some competent opinions in the internet:) Would be grateful for complex answer if possible, thanks!
Thanks for taking the time to write Данило Побережний. Also thanks for putting a Lynyrd Skynyrd song in my head. :)
While I think either console is more than enough to make nearly anyone happy, I'll try to address your concerns in an impartial manner:
1. Smoothness - Yes, it's true that XSX gets higher resolutions right out of the gate and it's well documented that the XDK/GDK migration hasn't been as quick as one would hope. While the PS5 inherited much from the PS4, the XSX is a more radical departure from the XB1. In early, less optimized titles, this won't show. Digital Foundry pointed it out too. In some cases PS5 did have smoother framerates, but we're seeing those fixed slowly but surely (ref Valhalla 1.04). In the long-term, I expect XSX to hold an overall advantage similar to Xbox One X over PS4 Pro. Nothing huge, but consistent.
2. Exclusives - Microsoft got smoked in the last generation on this. Their studio purchases (now incl. Bethesda) will guarantee a wide selection of exclusives on PC/Xbox (especially with Game Pass Ultimate). Now, I suspect that not all of the Bethesda titles will be exclusive. I can't guarantee it, but think the larger titles might have timed exclusivity (Starfield, ES6, etc.), but as a business, it would be insane to not milk them a la Skyrim.
In summary, as in past generations, I'll have and enjoy both. I straddled the Amiga/Atari ST line and the TRS-80 Mod I/Coco lines. I'll do so with consoles too - appreciating the potential and beauty of all of their designs.
For me it's always depends on what developers use and how easy it is to use it
The chain has to be pretty much perfect across every layer of the stack. And it never is. :)
@@StellarContinuumGaming also all developers are not created equal..comes down to talent and resources alot of times
Whose here after finding out the Xbox Series S is actually saving gaming optimization thanks to BG3 😮❤
So DirectStorage is behaving like RAM for the GPU? I know that the Xbox is using a asymmetrical architecture for RAM
DirectStorage is really a way to optimize how things get from an NVMe drive into RAM (either type).
Love your Videos, But I wanted to mention Sampler Feedback is a software feature, while on the other hand SFS is implemented on a hardware level. SF is a part of SFS.

Yep. Hardware facilitates the SFS for sure, but tried to keep the enhancements and the effective feature sets on different levels for clarity's sake. To some extent, everything is in hardware, but it's a valid point I wavered on a bit and tried to err on simplicity's side. Good point though.
Luv my Xbox Series 💪 X
It is a Well Built Silent Beast'😏
Do u think the architector will help the series?
Be great to understand how volocity and full rdna2 will effect games using these features as guess these are still some way out and no one is talking about what this could mean for games.
This will allow games to have a more dense and dynamic world with more variety. For example, NPCs can have more variety in their outfits, reactions, animations, etc. Buildings can also have more variety in their design. More variety in cars on the street. Better lighting and audio in games. Greatly reduced loading times. Having the scenery in the game change quickly. A lot of this comes from the fact that the new consoles can load data much more quickly. The faster GPU will allow for denser worlds. This means more things can be rendered/drawn in the field of view or with a higher level of detail.
Other than the SSD, the CPU upgrade was huge in the next gen consoles. This is responsible for so many things. If AI upscaling is introduced, and performs similar to DLSS 2.0, that will be another boost to performance that can be used to increase framerates or detail in the world.
Each gen games would look better but run at 30fps. This time games look better and run at 60fps, and some even reaching 120fps. That's all happening before the devs fully make use of the features of the consoles.
X'' -- material of - circuit in -- the BX'!" X''-- 2nd derivative - very nice view! I.e. < react!
Proved - it be: "Oriental Tribal -- only identity!"
I hope the next Forza Motorsport will make use and showcase this technology...
Do u know if PS5 has has some similar technologies in play? Their own version of Velocity architecture?
PS5 has a host of great innovations too. But sadly I barely have enough free time to write about Xbox. :)
@@StellarContinuumGaming Thanks for the reply mate...As usual stellar quality videos! Loved it 👍
it's not really similar..because they don't have mesh shading...they don't have directml ( not sure about this one ). and no its not really similar...ps5 "velocity system" is called oodle and it's pretty all in the ssd performance while xbox is using clearly much more feature with velocity system.
The PS5 sports a faster SSD and comparable hardware based decompression, yielding roughly double the bandwidth. Beyond that its IO complex accelerates significantly more aspects of file IO than the Velocity Architecture. It has dedicated co-processors that manage memory allocation, calculating the location of requested data within compressed files and GPU cache coherency. On Series consoles these aspects must be handled on the main CPU by either the host application or the DirectStorage API.
It's unknown at present whether there is hardware support of Sampler Feedback on the PS5's GPU, which would allow for the implementation of something very similar to SFS. Even if there isn't, UE4/5 supports similar tile based virtual texturing entirely in software which can provide much the same benefit though perhaps not as optimally.
The PS5 can't duplicate the Velocity Architecture. One thing not mentioned in the video is that each of the MIP levels of these textures are also tiled. Broken down into sub-squares that the Velocity system is able to load individually.This is a special texture file type that only the Series GPUs understand currently.
Interesting. what do you think when we will see the game uses this technology from 3rd party dev? Because its very convenient tool for multi-platform games
The transition has begun. Newer games will gradually utilize more features. Big games that are built from the ground up takes 3+ years of dev time. So starting around Fall 2022 for both consoles.
@@TheFirstRealChewywait!
dx12u is also available on ps5! I didn't know that
Not bad a new I/O throughout of 9.6G sounds pretty ok to me.
I feel smarter ..very clear
I think its a big deal, even though it works opposite to what UE5 is doing with Nanite. Nanite makes development time more efficient. SFS makes utilization of the hardware resources more efficient.
Going over everything. You have the SSD that makes data access faster. DirectStorage that further improves the efficiency of accessing that data from storage. A dedicated decompression block to take the load off the CPU. A higher bandwidth for memory accessed by the GPU, and SFS to reduce the amount of GPU data that needs to be read. On top of that there's an 8 core CPU with two threads per core. Outside of that there's a dedicated block for AI processing and the GPU has 52 CUs for parallel processing. Additionally, factor in the use of mesh shaders.
The GPU is a nice upgrade from the one in the One X, but everything else is a huge upgrade. The Series S|X and PS5 have a lot of gas in the tank. This gen is going to be exciting.
Ill be excited when we get games that actually utilize this tech. Its hard to be excited with no games.. Not only that Sony is currently handing it to Xbox Series X on the performance as well in 3rd party titles..
Yes. It's sad that Microsoft fell so far behind in instrumentation and build tools. But they'll catch up. I'm certain.
@@StellarContinuumGaming Instrumentation, profiling and build tools seemed to be broadly comparable last generation between the Xbox and PlayStation ecosystem. Do you have insight into why there seems to be such a gap in this new console generation?
@@jamesfmackenzie From everything I've seen and read, the PS5 uses an improved, but largely similar architecture (sliding power allocation, etc, notwithstanding) while Series' VA stack was sufficiently different that while at a high level tooling is fine and familiar, but VA-specific feature tools/instrumentation aren't nearly as mature yet. Again, going by what I read and hear from peers. I'm always interested to learn more if you can provide some insight. :)
From what we know, going from the XDK to the GDK wasn't as smooth as it was on the Playstation side. The XDK was also updated to allow for Series S|X targets, so some games are still being built using the XDK.
Another thing to know is that the GPU of the PS5 has less CUs (36) than the one on the Series X (52), but has a higher clock speed. The GPU in the PS5 have the same number of CUs as the one in the PS4 Pro. Games and game engines that are already optimized for this will get a nice boost. The higher the framerate, the greater the impact of small performance differences. So it comes down to how much optimization can be done. Its harder to utilize 52 CUs vs 36 CUs.
@@TheFirstRealChewy Thanks for the info. Definitely makes sense that it’s harder to “fill” and get maximum utilisation from 52 pipes vs 36 - especially if engines from last gen are optimised towards the lower number. Interested to see how this pans out as tools improve
latest reveal of xbox exclusive, the medium, doesn't really impress much...the fps are all over the place
The only thing that sucks is the xbox exclusives will be the only games to utilize all these new features. Most multiplatform devs are sony ponies.
Well, fortunately most engines have backend support that have been (and will continue to be) adapted to support these in a general way. But nothing will ever match hand-tweaked.
No it's not, playstation games are harder to port to pc
@@prodj.mixapeofficial6431 so I guess thats why games run better on the ps5 even though the series x has better hardware
@@danielallen7384 yes, it was made specifically for PS5. Almost all of the developers will keep in mind that the game must be ready to run multiplat so obviously they will chose MS tools. This is going to be the factor this generation.
