It's definitely a case of the PS4 UI being basic. Over half of that video is talking about the store.
Yup agreed, more than half actually goes into non gameplay related features,
Goes to show how much they are investing this time into PS5 and they ain't touched the 'create' button yet.
Edit: anyone else find themselves wishing they were already using the PS5 UI while playing on the PS4? Was just wondering about Apex while playing DS, hit home and was expecting to find some cards lol.
I thought the UI video shows the "create" menu? It looks fairly basic for now, but in what I would consider a "good" streamlined way. I'm also assuming we'll be able to use button shortcuts again (double tap and/or hold) to just take a screen or video without that menu coming up.
Yes they did, I think there should be more to it no?.
I felt that was just a basic screenshot or video grab mode like you mentioned using (double tap/hold)
Well on the right is an icon (two sliders) which is commonly used on phones to edit pictures, usually called adjust. This has has all your cropping, b/w and editing tools. I think though that they'll give more option to tweak screengrabs or videos.
That's really shitty, some games were only available on the desktop store.Old news but I got this email just now:
Finding it difficult to start playing anything atm after seeing the UI, It's all too slow and sluggish (on PS4 in comparison) . Will wait on PS5 to run through ng+ in GoT.
Not me, I'm waiting for the PS5 to check out Legends as well as NG+.
My brother and I were wondering if the PS2 titles that got emulated on PS4 will work on PS5. Sony didn't say anything about them and didn't include them in the list of unsupported titles so maybe there's a chance...maybe.
IKR!
All I'm saying is I really don't need to go back to home menu everytime to switch games, just a few cards to see if some friends are on other games I could join quickly or a checkpoint in another game I could quickly switch to and back.
The more I think of the PS5 UI practicality the more I look at my once lovely PS4 in disgust 😅
For me it's a feature to be able to download Games to your PS3 from the Webstore because the Ps3 Store takes up to 3 Minutes to even load and is kinda broken.
And Wishlists are awesome why you hatin them?
At this point it's definitely worth it to wait for PS5 to play NG+ in 60fps and even smaller load times.
Oh, I noticed those.
I'm thinking a bit deeper, kind of like some patent suggested.
Like sharing of activities or 'takedowns'.
Maybe I beat a DS boss in a very good time, I could share that with some friends like a challenge or something, beat a friend's racing highscore? Share the activity, Next time he's on the game, the card pops up and be like 'yo, mubrik smoked your time' lol.
My expectations are a bit higher but that's due to a usually quiet Sony bragging about a new button, I'd expect more than just cropping and some filters also blame cerny. The man had me hyped since March.
So i started my Playthrough of Silent Hill for real this time and it's insane how good this Game is with it's razor sharp atmosphere. Walking through those empty streets and hearing nothing but your radio crackling occasionly is always unpleasent. How surreal it all is seeing those big craters in place were once was a street that now lead to a bottomless hole, blocking your path.
It's all so well done. I just arrived at the School and had to stop because while i love horror Games they also take quite a toll on me during my first playthrough when i don't know them. Can only play them in shorter bursts.

Honestly - not trying to doom and gloom here - but I can picture a scenario where Sony just leaves the industry after this gen and PS5 is the last Playstation.
If walled gardens are judged to be illegal and Sony loses that revenue; while MS, Google, and Amazon buy up all the third party devs/publishers for ramping up streaming wars...I don't see how Sony survives in that environment.
Now, I definitely don't think that's at all likely. It's more like an absolute worst-case scenario while still being kind of feasibly possible.
But I do think we're going to see a lot of major, fundamental changes in the game industry in the coming years. And a lot of it I don't see playing out to my liking. If we do ever end up in a scenario where consoles are basically dead due to the loss of walled gardens, and they become essentially branded, expensive pre-built PCs where you then have to subscribe to half a dozen different services just to access the games...I don't think I'd even bother with new games at that point. I'd just become a retro-only gamer.
Even my naturally pessimistic self doesn't actually expect that to happen, but there's a ton of uncertainty about the future of the industry that's making me nervous lol.
Best to just shove all that to the back of my mind though, as none of it is in my control. Just trying to focus more on all the good stuff we have to look forward to over the next couple years and enjoy this great time for games while it lasts. Just have to wait and see what the future holds, and deal with it once it gets here.
Your pessimism should be what's leading you to believe that Epic won't win in this. In this country, where we let companies take so many incredibly dangerous, monopolistic, anti-consumer positions, (think telecom/broadband consolidation, "clickwrap" agreements, forced arbitration, drug price manipulation) *this* is going to be the place where our courts draw the line? No way.
Probably a mistake, but Amazon Germany lists Gran Turismo 7 for November 12th 2020...
https://www.amazon.de/Gran-Turismo-...+7&qid=1602876928&sprefix=gran,aps,240&sr=8-1

Well, 2:40 PM in my part of the world and I never saw any of those minor patches that I mentioned seeing on Reddit here in North America. So I'm thinking they aren't any performance improvements and just region specific fixes to prepare for PS5.
Sonys one more thing moment! Lmao but yeah prob a mistake. The only way we know if its remotely possible is when games get rated. the stuff overseas gave away demon souls being a launch title
FYI the artist for that sick Miles Morales Famitsu cover is Tim Tsang, Creative Director at Marvel Games
Hopefully Marvel releases it as a poster in the future
Hopefully Marvel releases it as a poster in the future
Sony shadow dropping absolutely killer titles on launch day. 😎
Amazon UK updated my accessories to Nov 12th... Still can't find a charging station. Main thing I wanted.
hello! new article of PS5 in japan.
Japanese tech journalist's commentary and interview with Otori-san (1/2)
(There are some images at the link.)
Zenji Nishikawa's 3DGE: I'll tell you how to make PS5. The internal design of the PS5, according to a mechanical designer(in Japanese)
On October 7th, 2020, Sony Interactive Entertainment (SIE) released a disassembled video of its then unreleased next generation gaming console, the PlayStation 5 (PS5). The video caused quite a stir, as the company released a video explaining the internals of the PS5 in great detail before the product's release. If you haven't seen it, please watch this one.
I had a chance to interview Mr. Yasuhiro Otori, who introduced the inner workings of PS5 in this video. In this article, we will explain the details of the PS5 based on the information we got from the interview.
Mr. Otori is a specialist in housing design and internal structure design, especially cooling design, and he will be giving a presentation at CEDEC 2014 on the internal structure of the PlayStation 4 (PS4) titled "How the PS4 is made, and what's inside the PS4 is revealed! I have also done the following. For those interested, see the report by the author.
First, let's review the basic information in the PS5 disassembly video
First, let's get some basic information on the PS5's physical structure based on the disassembly video released by SIE.
The PS5's nominal body size is 104 (W) x 260 (D) x 390 (H) mm when placed in portrait mode. The PS5's nominal body size is 104mm (W) x 260 (D) x 390 (H) mm when placed in portrait mode, which is considerably larger than the PS4's nominal body size. Mr. Otori says in the video that it is "a size larger than the initial PS4".
However, as you can see as the video progresses, the PS5's curved surface design is narrower from the center of the body to the edges, so the actual volume of the regular PS5 is about 7.2″, and the digital edition without the optical drive is about 6.4″. The volume of the competing Xbox Series X is about 6.86. so it's about 1.05 and 0.93 times.
The back of the PS5 was not available for filming at the media event, so this is the first time the video was shown in disassembled form.
There is a slit on the upper part of the front side for air intake, and the back side has exhaust holes all around.
On the front, there are USB Type-A ports for USB 2.0 and USB Type-C ports for USB 3.2 Gen 2.
On the back are two USB 3.2 Gen 2 compliant Type-A ports, a 1000BASE-T wired LAN port, an HDMI 2.1 output terminal, and an eyeglass-shaped power connector.
The PS5 comes standard with a dedicated stand that can be used for both vertical and horizontal installation. The stand is held in place with coin screws when the unit is placed upright, and the claws of the stand are hooked to the side of the PS5 unit when it is placed horizontally.
The white cover panels on either side of the PS5 are made of ABS resin. They can be removed by sliding them off.
When you remove the cover panel, the most noticeable thing inside is the air cooling fan. The fan is 120mm in diameter and 45mm in thickness, and it goes through the body.
In addition, there are two dust catchers on the right side to collect dust, which can be vacuumed up by the vacuum cleaner. The cover panel can be easily removed so that users can easily maintain it themselves.
Next, let's take a look at the additional SSD slots, and while the PS5 features a high-speed SSD, there was a lot of confusion as to whether the standard SSD can be replaced when the storage capacity is increased, or whether it should be added to a separate slot. In the disassembly video, it was revealed that an M.2 slot was available for adding an SSD, which settled the issue. The connection interface is said to be PCI Express (PCIe) 4.0 compatible.
In the movie, the optical drive covered by the steel chassis is removed to reveal the main board. The interesting thing is that there is only one main board, while the Xbox Series X has two boards, a main board and a sub board. This is one of the points that we would like to pay attention to as it shows a big difference between the two products.
The SoC (System-on-a-Chip) on the main board is a dedicated APU that integrates a CPU core based on Zen2 and a GPU core based on RDNA 2. Aside from the main memory, the standard SSD is also directly attached to the board, so it cannot be replaced by the user, and the board appears to have a total of six flash memory chips, three on the front and three on the back side of the board.
The video also shows a customized SSD controller from SIE. Just to add to the misunderstanding, this SSD controller is not equipped with the data-expanding chips necessary to achieve PS5's high-speed data transfer. The difference is that the PS5's SSD controller has a 12-channel configuration, whereas a typical SSD controller has 8/16/32 channels.
The scene that follows is the climax of this video.
In the following scene, Mr. Otori revealed the use of liquid metal for the thermal interface material (TIM) between the APU and the heat sink in the PS5.
Although liquid metal is an excellent thermal interface material, it is not actively used in consumer electronics due to its tendency to corrode aluminum. The fact that PS5 uses liquid metal on purpose is interesting. According to Otori, SIE has been preparing for the adoption of liquid metal for more than two years.
The heat sink that cools the APU is about 30% of the size of the housing. Six heat pipes extend from the part of the housing that touches the APU, which has the highest thermal density, towards the heat sink. Mr. Otori says, "Although we used standard heat pipes, we were able to achieve the same level of performance as a vapor chamber by improving the shape of the heat sink and airflow design.
The power supply unit that was removed at the end is said to have a rated output of 350W. Since it is a rather high power supply unit, we can clearly see that it also accounts for a large portion of the PS5's overall volume.
Ask about SSD expansion, a concern for gamers
Now that we've reviewed the PS5's internal structure, let's take a look at some of the information we got from our interview with Otori.
The PS5 can use M.2 SSDs for PC's that support PCIe 4.0. However, there are several products with different board sizes for M.2 SSDs. I wonder how much of it can be built in?
Otori: PS5 supports board sizes that are 22 mm wide and 30 mm/42 mm/60 mm/80 mm/110 mm in length, which are common for M.2 SSDs, and the studs and screws that hold the SSD module in place are built into the SSD expansion slots from the start.
It's a minor detail, but some M.2 SSDs have heat sinks attached to them. Are there any precautions that need to be taken when installing such SSDs in the expansion slots?
Otori: The physical design of the heat sink is designed so that it can be stored as long as it is no higher than 8 mm from the board surface. Although there is a metal cover on the expansion slot, it is best to avoid contact with it.
If you install an SSD with a tall heatsink, it may interfere with the metal cover. The chassis and screw holes to which the metal cover is attached are made of plastic, so there is a possibility that they will be damaged. For this reason, it is likely that you should avoid using an extremely tall heat sink for an additional SSD.
Also, it is well known that M.2 SSDs that support PCIe connections generate heat under high loads, and some PC motherboards are equipped with heat sinks for M.2 SSDs, so we wonder what kind of innovations are used in the PS5.
Otori: We have two exhaust holes for additional SSD slots. Because the slots for expansion are located near the intake fan, the structure is designed to suck out heat from the exhaust holes with negative pressure.
The secret behind the stand, which can be placed vertically or horizontally
Along with the SSD, we also found out some interesting things about the included stand, which is likely to be of great interest to readers in terms of "how to set up the PS5".
The height of PS5 is nearly 40cm when placed vertically, so the center of gravity is also suitably high. So it is easy to understand why PS5 is attached with a special stand as a standard accessory to prevent it from falling down.
As mentioned above, the stand can be used for horizontal installation, but in the disassembly movie, the stand was rotated when switching from vertical to horizontal installation. This gimmick may have intrigued many people. What is the meaning of that rotating mechanism?
Otori: The PS5 stand looks simple, but it's quite elaborate.
If you look closely at the stand, you can see that the indentations where PS5 is placed in portrait mode are inclined on both sides. When the PS5 is placed horizontally, this inclination is designed to support the white cover panel. However, the curved surface of the cover panel and the shape of the stand do not mesh with each other when it is oriented as it is.
So we have to rotate it. When the slide is rotated, the non-slip pedestal in the dent in the stand rises up. At the same time, the hook to fix PS5 on the stand moves to the designated position. The raised non-slip base and the slopes on either side of the base catch the curved surface of the cover panel perfectly.
Depending on the stand, the PS5 can be placed either horizontally or vertically, but does the way it's placed make a difference in heat dissipation performance?
Otori: This is a question we are often asked. As a designer, I can say that there is no difference in cooling performance between vertical and horizontal mounting. I know that some people think that the chimney effect makes the vertical installation more efficient in terms of heat dissipation. However, the chimney effect is at the level of measurement error in a cooling system with an active fan (electric fan) installed. Both horizontal and vertical mounting will perform as specified. Personally, I like the vertical installation, which shows the PS logo correctly.
Do you use the latest computer aided engineering (CAE) to analyze how the air flows through the chassis?
Otori: CAE is sometimes used to optimize the airflow of individual parts, but we don't use it to design the whole thing; we develop it by conducting real-world experiments. Specifically, we made a transparent model of the chassis and observed the dry ice smoke flowing through it, and took temperature readings in each part of the system as we made improvements.
Why is PS5 so tall?
At about 390mm, PS5's height is the tallest in PlayStation's history. This protruding vertical (or horizontal when the unit is placed on its side) shape seems to be a secret too.
Otori: After the design department provided us with the required dimensions, we began to consider the design of the PS5's body. For example, we reduced the height and widened the width by that amount. This time, however, the design department asked us to make it look thinner when it's placed on its side, so we decided to make it taller and narrower.
Hearing this story alone, it sounds like the result of focusing on appearance, but of course, that's not the only thing we did. In fact, there is another major benefit of this design, which is to reduce the number of mounting boards. That is to reduce the number of mounting boards. If the width is made wider, it would be difficult to install on a single main board, resulting in a double-board configuration with a main board and a sub-board.
I'm not sure if this is due to the increased width of the Xbox Series X, but the system is actually made up of two boards.
Otori: Having two boards increases manufacturing costs and thermal design challenges. We wanted to make it look thinner when it is placed horizontally, and we wanted to keep the cost down with a single board.

Zenji Nishikawa's 3DGE: I'll tell you how to make PS5. The internal design of the PS5, according to a mechanical designer(in Japanese)
Why do we use liquid metal in the main cooling system's TIM?
Next to the exterior, I'd like to talk about the main board, as SIE calls the front side of the board "Side A" and the back side "Side B", so this article follows suit.
As mentioned earlier, the APU, the main processor, is mounted on side A. Three SSD flash memory chips are mounted on each side of the board on both sides. The edge of the board has a large slit to accommodate the fan.
Otori: The electric fan is designed to blow air on both sides of the board, side A and side B. The material of the fan is polyvinyl fiberglass. The fan is made of glass fiber polybutylene terephthalate. The advantage of this material is that it is strong and its shape is minimally deformed by heat. The number of vanes is calculated based on the balance between the required positive pressure and air volume. The fan is designed with enough margin to avoid the failure of the main unit even in a very severe environment.
The fan is 120mm in diameter and 45mm in thickness, which is quite large and thick for an electric fan mounted on a game machine. The reason for this is to achieve a high level of quietness by rotating the large fan slowly. Although the company does not disclose the nominal fan noise level, it can be said that "under normal usage and specification conditions, the fan is quieter than the early PlayStation 3 and PS4".
The cooling system for the APU on the A-side of the main board was carefully designed by Otori's team. The best example of this is the use of liquid metal for the timings.
Otori: We have wanted to use liquid metal for a long time. However, since liquid metal is conductive, if it leaks to the board side, it will cause a short circuit. Above all, liquid metal is highly corrosive to aluminum, which is used for components such as heat sinks. When handling such materials, measures are required for manufacturing facilities. We spent more than two years preparing for these problems.
Although the composition of the liquid metal and the manufacturer of the joint venture were not disclosed, it is said that a common gallium-based alloy is used for the liquid metal-based TIM. However, in the interview, he emphasized that it was a proprietary product custom made by SIE.
In the disassembled video of TIM, you can see a sponge-like component around the APU part. This prevents the liquid metal from leaking out to the board side.
Liquid metal TIM also exists for PC CPUs and is used among CPU overclockers, for example. However, as Otori says, there are problems with conductivity and corrosion. There is even a warning to use copper-based heat sinks in TIM for PCs.
Why did you spend more than two years to use such a difficult material?
Otori: The main reason is cost. In thermal design, you have to put the cost close to the heat source. As a general thermal design metaphor, let's say you spend 10 yen for a TIM and 1,000 yen for a heat sink in the cooling structure of a certain system. If you change to a 100 yen TIM, you can get the same cooling effect with a 500 yen heat sink. In other words, you can reduce the total cost.
Even after overcoming the difficulties in handling and manufacturing, liquid metal was finally used in PS5 to achieve a great effect.
The main heat sink that cools the APU is connected to the board through the A-side shield plate made of galvanized steel plate (SPCC: Steel Plate Cold Commercial). The APU portion of the A-side shielding plate has a square hole in it so that the block part of the heat sink will directly contact with the APU.
Otori: The heat sink is made of aluminum, but the block in contact with the APU is made of copper. However, can you see that this block is plated in silver? This is to prevent corrosion from liquid metal.
As mentioned earlier, gallium-based liquid metals are highly corrosive to aluminum, but copper is said to be able to withstand that. However, according to the tests conducted by the PS5 development team, even copper is not completely resistant to the gallium-based metal used in this project, TIM, so they are also taking measures to protect it with plating.
Cooling the back of the board was more difficult than the surface
The B-side, which is the back side of the machine, has many highlights as well, and the B-side is dotted with reasonably large heat sources such as GDDR6 memory, DC/DC power circuits, and flash memory chips.
How are these parts of the device being treated for heat?
Otori: Actually, we are more concerned with the cooling of the B-side of the device than the A-side. Looking back, it may have been easier to deal with side A because we could foresee the high heat source in advance (laughs). In fact, the B-side has as much heat as a PS4's APU, so we had to cover the B-side. That's why the shield board covering the B-side can be used as a heat sink.
According to Otori, the B-side of the board is not made of galvanized steel, as the A-side is, but of aluminum, which has excellent thermal conductivity and heat dissipation.
The outer side of the aluminum shield board has a small three-dimensional heat-dissipating fin, and the inner side where it makes contact with the B-side has a heat pipe, making it look like a shield board as well as a heat-dissipating plate. This heat pipe is connected to the heat sink mainly for the purpose of heat transfer from the DC/DC power supply circuit. The wind from the cooling fan flows through the shield board and wipes away the heat.
By the way, if you look closely at the inside of the shield board, you can see that the ground surface is coated with gray material. What is this?
Otori: It's TIM. It's applied to the shield board, the DC/DC power supply circuitry, the GDDR6 memory, the SSD flash memory and the part where the heat source is installed. It's used to transfer heat from the heat source to the shield board.
The TIM applied to the shield looks like a round rubber sheet, but it is in liquid form during the manufacturing process. It hardens over time and eventually takes on a rubber-like texture, according to the company. The chips, which are the heat source of the chips, are expected to have a certain amount of variation in height, but this TIM can absorb that variation because it is in liquid form when it is applied.
Otori: The use of this TIM is closely related to the manufacturing process. The process of peeling off the backing board is difficult to accomplish with a robotic arm. The injector method (to inject the liquid TIM) is a good match for automatic machine production.
Optical drive and power supply unit
Let's take a look at the remaining optical drive (UHD BD drive) and the power supply unit. The optical drive is completely enclosed in a steel case, which appears to be a disadvantageous structure from a heat dissipation point of view. Why is it designed like this?
Otori: As you mentioned, we focused on quietness and vibration control. Optical drives, which are capable of high-speed reading, generate a certain amount of noise and vibration when the optical discs spin at high speeds. In some cases, a disc with a sticker affixed to the surface of the disc may be inserted. Since the weight of such discs is imbalanced, they generate more noise and vibration. This is the structure of the optical drive in order to reduce noise and vibration.
The optical drive module is equipped with a double insulator at the point of contact with the main body chassis. This works as a suspension to absorb vibrations from the optical drive module.
The power supply unit has a capacity of 350W, which is high output for a game machine. It is not a fully enclosed unit like the optical drive because it generates a fair amount of heat. There are slits at the front end and the end of the plastic case, so that the air from the air-cooling fan goes out through the slits.
The air from the fan is designed to have a "crosstalk curve" (a curve whose curvature varies in proportion to the length of the curve) and is designed to collide with the intake slit of the power supply module.
The cooling design leaves the possibility of further improvement
In addition to the temperature sensor inside the APU, PS5 has three temperature sensors on the main board to control the fan speed based on the internal temperature of the APU and the highest temperature of the three temperature sensors.
It is interesting to note that these fan control parameters will also be updated via online updates.
Otori: Various games will be released in the future, and data on the APU's behavior in each game will be collected. We have a plan to optimize the fan control based on this data.
The PS5's thermal design, including the speed of the air-cooled fans, is said to have a generous margin of safety. If a game is under heavy load for a long period of time, they can increase the fan speed to enhance cooling performance, even at the expense of quietness. This is an interesting story.
Lastly, Mr. Otori had a word for PS fans.
Otori: We are working at full capacity in the factory to make this product available to those who want it. We've done our best to make it available to those who want it, so please buy it!

Why do we use liquid metal in the main cooling system's TIM?
Next to the exterior, I'd like to talk about the main board, as SIE calls the front side of the board "Side A" and the back side "Side B", so this article follows suit.
As mentioned earlier, the APU, the main processor, is mounted on side A. Three SSD flash memory chips are mounted on each side of the board on both sides. The edge of the board has a large slit to accommodate the fan.
Otori: The electric fan is designed to blow air on both sides of the board, side A and side B. The material of the fan is polyvinyl fiberglass. The fan is made of glass fiber polybutylene terephthalate. The advantage of this material is that it is strong and its shape is minimally deformed by heat. The number of vanes is calculated based on the balance between the required positive pressure and air volume. The fan is designed with enough margin to avoid the failure of the main unit even in a very severe environment.

interesting so you can use a heat sink With the SSD if you want to, also they have all the screw for you to mount the SSD Into the system. I wonder if their list or approved ones will say its usable with, or without a heat sink within the system.
Agreed, Horizon was in that first show and has been in dev long enough to still be cross-gen so I definitely think Guerrilla's heavily targeting 2021.
wow this is some interesting stuff. Also the amount of money they could save just by using the expensive TIM. Going from 1100 yen to say 600 is a huge amount of savings. Also how they will monitor and be able to adjust firmware to adjust based on games.
I expect an article by you know who saying the PS5 will be louder than a jet engine based on this.
