The PS5 will be released in a few hours. I want to talk about the PS5 SSD before PS5 release. In this thread I'll try to make some simple analogy to compare the meaning of PS5 high-speed SSD. AIn addition, i wanna anticipate the mode of future games. I tried to simplify the analogy of PS5 SSD , and the relationship between the value might not be very specific.

The performance of cgpu is like the decoding ability of static pictures. Assuming theoretical values, the decoding capability of Xbox Series X or high-end pc architecture is stronger than PS5. The former can decode and present pictures of 4k level, while ps5 can only decode and present pictures of 2k.

Statically, XSX's picture is much more beautiful than that of PS5 .

Now, the request is coming: you must change a picture every second.

Xbox Series X:


(set) It takes 12g of material to generate 4k level pictures. The bandwidth of the material obtained by xsx is 3g/s.
The result is that xsx cannot complete the above requirements in 4k mode, and must read the disk for 4 seconds to present the picture.
Or, downgrade to 1080p mode. In order to change the picture every second.
In conclusion, xsx either presents ultra-clear pictures in an intermittent manner, or smoothly completes tasks in a low-resolution manner.

ps5:

(set) 9g is needed to generate 2k level pictures. The ps5 material acquisition bandwidth is just 9g/s.
Result: ps5 can always present high-definition pictures smoothly.

PS5 SSD

An example in reality:
back in the era of ps2, we will not ask gta sa to be on par with Silent Hill 2. The hardware is the same, why is the picture so different? Because the gta open world material acquisition method is random CD-ROM reading, the highest image quality in the entire world must reach a certain balance between the material acquisition bandwidth. Even if ps2 still has huge graphics potential, it cannot be used. Otherwise, there will be serious violations of the dynamic picture, so simple.

But, at that time, the architecture of ps2 was ssd (common type)? That means that even an open game like gta can run at the level of graphics like Silent Hill 2, God of War 2, Soul Calibur 3, and Tekken 5. Because the EE of ps2 can be done already.

PS5 SSD

Imagine running gta sa with the graphic quality of Soul Calibur 3, does it feel a little bit like gta4 on ps360. Say ssd can bring the picture to improve, to put it simply, this is the reason. The essence of ssd is to improve the bandwidth of material acquisition and material management.

In 3D games, every step you take will cause your vision to change. If the traditional caching method is used, the materials are all ready-made and do not need to be obtained.

But what if you use random reads without caching? It means that the material capacity "updated" in each frame is equal to the upper limit of the bandwidth. In this case, the fineness of the picture is by no means comparable to traditional caching methods.

To give another simple example, the field of vision: the traditional caching method, the player looks forward, although he cannot see the back (outside the field of vision). But the graphics around and behind have been read and generated.

Random reading method, the player still looks forward, all hardware resources are used to present the landscape in the field of vision. Don't take the scheme of generating the back graphics in advance Looking back suddenly now, the material in all hardware resources is quickly "updated to generate the landscape behind.

With the above two solutions, when the material bandwidth is high enough, the latter's picture will be far superior to the former. And yes cgpu does not put forward additional requirements.

The concept of "out of sight" is particularly significant for vr.

From the above perspective, there will be such a conclusion. Dafa's super-high-speed ssd, for traditional small box games, such as the God of War Tekken may not necessarily gain obvious advantages in terms of picture and experience. But for an open world such as gta, a large box court such as Ace Combat and vr, it will bring earth-shaking changes.

PS5 SSD

Because of its seamless material, seamless model, and no vision Seamless, seamless view. Under all kinds of seamless, the picture is as good as the small box game. It can be said that rather than choosing a framework, it is better for PS5 SSD to bet on the type of future games. Dafa believes that future games The basic type must be open world, VR. So, in order to get a perfect experience for this type of game, we chose the ssd architecture.

What should be the experience of the open world and vr? On the surface, it is continuous, smooth and far-reaching. Basically, it is a sense of existence in the world.

The significance of high-speed PS5 SSD is to eliminate as much as possible the process of destroying the "existing sense".

Whether PS5 SSD will bet on success this time, I don’t know, but I am very pleased with this idea of designing the console around the game type. This is the idea of the game console: a computer specialized for the simple function of the game.

In the future, the small box will only exist as a classic game experience. It is no longer a trick to rationalize frequent disk reading.

This different development environment and ideas, as well as the fundamental differences in hardware, will bring difficulties to the transplant. Perhaps third-party games will not take advantage of ssd in order to reduce porting costs in order to accommodate multiple platforms. However, in exclusive games, players should have the opportunity to feast their eyes and immerse themselves in the existing world.

PS5 SSD

Can xsx and pc equalize the specialty of PS5 SSD by increasing the speed of ssd? Personal estimates are difficult for xsx. Because high speed is one aspect, and the other is more important, that is, "random". The performance associated with randomness is latency. If the delay design is not done in advance on the protocol and hardware, it is impossible to achieve seamlessness afterwards by simply increasing the continuous reading speed, especially the seamless switching of the field of view.

Now xsx hardware and software environment has been set. Can't move without action. If the enhanced version comes out, make up the short board of ssd. Then immediately face the problem of incompatibility between the standard version and the enhanced version. There is a big difference between the two development methods, and it can't be solved with a patch on the game.

xsx has to work hard in the traditional small box house. The open world will be at a disadvantage. In VR, this gap will widen even further.

It is true that xsx should have better resolution and frame rate. Each has its own strengths, why is there a gap? There are examples in history. dc vs ps2. It is high-definition high frame vs. low-definition low frame. We know the advantages of dc, ps2 is overclocking and can not catch up. But after all, the graphics of dc are a little bit shabby and pulled apart by ps2. The past calendar is in sight. Is xsx really like dc? Winning on the screen or not? These all depend on the game type and exclusivity.

What about pc?

In fact, pc has nothing to say. There are no two identical pcs in the world. In the end, which pc, and which price pc can represent all pcs?

It's no surprise that PCs have products that can match or even exceed ps5ssd in terms of protocol and hardware layer. The pc is a building block monster, and there is nothing it cannot do. The question is, why do you want such fast io on a personal computer?

In fact, pc is an economical open bus. In the era of vr warrior 1, voodoo appeared. The essence of the high-performance graphics card is to load the special computer of the game console onto the bus of the pc. Although until now, the vast majority of people have not even used nuclear displays adequately.

The PC repeats the old trick, loads the ultra-high-speed SSD to the bus, sells it at a good price, and then standardizes it. Everything is inevitable and has limited meaning to ordinary users. But someone will always need it. Looking back over the next few years, it is possible to prove the pioneering nature of the ps5 architecture.

Now some people say that Dafa is fooling with ssd. In fact, as long as you think about it, the next generation of Xbox will also have to use ultra-high-speed SSD.

Finally, make an expectation of the future game mode.

If the bandwidth of PS5 SSD is fully utilized, we will find out. The capacity of this solid-state hard drive is too small to fit several scenarios. The ue5 demo is only a few minutes, the actual exploration space is extremely limited, and the material capacity has reached 150g. Don't say that PS5 SSD can't fit a complete game. Even if it can be installed. Game manufacturers can't afford such a big game.

The possible solution is mod. Game manufacturers provide a basic material solution. Other parties provide enhanced mod programs. This model may become the norm.

The capacity of a game is no longer fixed. Different mods make the game extremely huge. So large-capacity hd will inevitably become the standard for ps5. Only part of the game is loaded in the ssd, and it is like returning to the thinking of the box court. This is the next generation of the box court. Think about the ps5's Ace Combat, I am really looking forward to it!

very detailed.
On the technical route, xsx will go to high-definition, high-frame, the video memory will be loaded in the traditional way, ps5 will be very aggressive, using 30 frames, you can achieve flash refresh at the frame level, thereby breaking through the memory capacity limit. However, as lz said, several games cannot be installed.
But not to install a complete game, the developer will change his mind and return to the era of the cassette player, carefully arranging those resources to be reused, but traditionally it is the reuse of resources in memory. This time is to use this The scope is expanded to ssd, which can be adjusted and displayed on the screen at any time

Compressed, PS5 is 8-9G/S, isn't XSX 4.8G/S, and Microsoft has shrunk to 3G/S again? It's been a long time since I followed the news

It seems that Sony really depends on an SSD?

But can't the same reading effect be achieved by adjusting the frame rate? For example, from 120 to 60, I don’t think the difference between 120 and 60
