    Default PlayStation 5 Launches Holiday 2020

    Atmos is a means of packaging Object Based Audio for playback on a limited number of speakers, aggregating the objects. What Sony is offering is the complete object based audio soundscape as generated in-game - each sound object discreetly delivered.
    But you are always going to have the limited amount of speakers no matter what the input source is so that problem remains on HiFi regardless of Sony or Microsoft or anyone else for that matter.

    I’m not aware that either Atmos for Headphones or Sonic have this “virtual speaker” limitation you speak of and both can also output all the objects directly as generated in game.

    I just don’t know if anyone has fully used it to date and the bigger problem with the Xbox is that you never know exactly what is being offered and I hope with next gen that changes with some form of popup identifier or a selection in game and on the box art or description.

    I long for a day when you don’t need to go change the audio settings in every game every time you flip between HiFi and Headphones and that it just does it automatically.

    New preorder stock has been allocated for the UAE going on sale tonight and tomorrow. I really hope I manage to secure one this time.

    It doesn't pertain to a surround setup (EDIT: since we're talking about virtual space).

    They do and no they can't. My earlier post might help you understand how the technology works a little better.

    EDIT: They only decode what is in the Atmos mix, which groups objects for playback over a fixed number of channels (only 16 for Windows and Xbox One). Atmos is a go between, Sony's implementation doesn't require one.

    Maybe this is more about the receiver you're using? I've never needed to change anything (using PCM output, virtualisation applied to PCM output by the AVR when using headphones).

    In addition, M.2 SSDs corresponding to PCIe connections are well known that heat generation at high loads is a major problem. Some PC motherboards have heat sinks for M.2 SSDs, but what kind of devices does the PS5 use? Mr. Liu: Two exhaust holes are provided for the expansion SSD slot.

    Since the expansion slot is located near the intake fan, it is structured to absorb heat at negative pressure from the exhaust hole.

    .....

    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.

    The fan is made of fiberglass polybutylene terephthalate. The advantage of this material is that it is strong and the shape deformation due to heat is small. The number of feathers is calculated from the balance between the required positive pressure and air volume. Even in a fairly harsh environment, the main body is designed with plenty of room to prevent it from failing.

    A thick fan is adopted, and the wind is sent to both A side and B side.
    The size of the fan is 120 mm in diameter and 45 mm in thickness, and it is quite large and thick as an electric fan implemented in a game console. This is to achieve a high level of calm by slowly turning the big fan.

    ...

    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.

    The one thing that Sony console hardware lacks is quality control, I can just see one batch having sub-par fans which gets loud under these extreme circumstances and then the issue gets blown out of proportion.
