yikes better get a wireless headset then

Yeah, as I work in music 256 is closer to 320 and the mic quality doesn't sound clean enough to reach those numbers. So 128 is what I'd assume, but don't quote me lol. Could vary depending on the actual mic used.

EDIT: My bad. I'm speaking from the device itself. I might have to research this but it's dependent on the device's audio output.

The audio block that XSX is using doesn't seem to be doing what tempest is. Hmmm
I expect Tempest Engine to be unique to PS5, they pretty much used lessons learned with CELL to build the audio block using a CU as the frame

EDIT: My bad. I'm speaking from the device itself. The Bluetooth, I'm not totally sure on what the stream capabilities are. It should be able to stream any type of quality. I might have to research this.
I meant to ask the output audio quality from headphones connected to controller, is it limited to 128kbps?

The mute mic icon belongs to that wide button above it. That hole is the exact same placement and size as the headphone jack on the DS4

The hole is actually more lozenge-shaped than round.
Might be perspective, but look closely and it doesn't seem to be. Also seems to small to be 3.5mm jack.

Yeah I went back and edited my comment (probably wrong again too). I have to research more on this. Apparently the bitrate format used is AAC? So they should run anywhere from 192-320kbps. At least PS3 did it.


Another Article:


Designed as a successor to the MP3, AAC files come in a similar range of quality options. Even the Bluetooth version of the codec is highly flexible, as we’ll see in a moment. The AAC audio format supports audio quality up to 24-bit 96kHz, but in the Bluetooth space we are limited slightly below CD quality at best.

And below CD quality is 160kbps and downward. Not entirely sure what to make of this info yet.

Where would you plug it?

Ideally directly into a headphone jack on a controller, instead of some pass-through an USB port. That hole at that bottom could very well be a mic given the symbol on top of it. Take a look at your DS4, it has a dedicated headphone symbol just above the audio jack.

Besides, I'm more concerned about my Astro Mixamp TR and A40 headset working with PS5. I dropped $284 on them last year, would hate to only get use out of them for an year lol.

I'll research this further but wasn't the ds4 audio quality limited? I'd assume wireless headphones provide better quality

It seems the face buttons are on a curved surface now rather than the flat surface we've had up til now. Gonna take some getting used to in competitive games.

The V-shaped devkit design makes much more sense now.

For me, the touchpad looks kinda similar to the devkit’s V-shaped vents. And those clear buttons scream LEDs to me, so we might still get coloured buttons but in the form of LED lights. Just imagine using this thing in the dark.

TV Company called SKY in UK had these receiver boxes...

I have a feeling PS5 will look something like this... futuristic, sleek, black, white, and curvy.

Kinda matches the DualSense.

I think I've figured out how the variable clocks are a genuinely positive thing for PS5. It will lead to overall better (more stable) performance of games, meaning what's important... Framepacing and framerates can and probably will be rock solid 99.9% of the time on PS5.

Until today, I've remained quite confused about the whole thing, but it's actually genius and quite logical.

Based on the last DF article, the PS5 devkit doesn't boost, but instead has profiles which the dev programs and optimises against. So the devkit has locked clocks at whatever, say a fixed 10.0TF/3.3GHZ. The dev will feel comfortable in optimising right up against this limit with the knowledge that on a production console, the clocks will be variable and they'll boost up to their max frequencies to give the game that extra performance ceiling for those split seconds when the game engine requires it. This is what is meant by "continuous boost", there is clearly no throttling going on here.

This is the "new paradigm" that Cerny mentioned. It's not just a new paradigm in console design, but also a revolution in how devs normally optimise their games.


Let's take the XSX, you have a max fixed clock. You're a dev and you program against the peak theoretical limit of 12.15TF. However, suddenly there is a ton of action on screen when you're playing the game, hitting that GPU limit and there is no more power left so you'll experience stutters and dropped frames. Of course, extensive testing could mitigate all this and for sure, top studios may have the time and budget to do so, but this system is more difficult and more prone to dropped frames.

This isn't a slight on XSX... just that a game will never actually optimise up to the peak theoretical limit of the GPU, because there will always need to be some left over.


Bottom line, I think this optimisation phase of development is where the term "lazy developers" comes from... It's the spit and polish, it's what DF is testing for mainly... how steady is the framerate and how optimised is the game engine for the platform to be able to deliver a consistent frame time. With the PS5, it would appear the boost/variable clocks are there in the console to compensate for those instances that a dev did not foresee when developing their game and have that extra performance overhead to maintain that steady performance for us, the end user. It simply saves time and headaches. It really is a new paradigm and it's really ingenius.

Where this new way of optimising games will come in most importance is for VR where a steady, high framerate is absolutely key to reduce the chance of motion sickness.

PS5, to me, screams "steady, consistent, performance". Absolutely contrary to what the "variable clocks" makes it sound like. That is the true genius of it.

It seems like you are in the right way of thinking - but maybe for the wrong reasons – so I’ll try and explain what I took from Cerny’s counter intuitive description of the setup and generate some dummy graphs as a pictorial aid.

If we start with a simple power equation

Pow(watts) = Potential(Volts) x Current(Amps)

And in this equation lets say we crudely put it in terms of clock rate and CU_ratio in use

Pow(watts) = GPU_factor x (GPU_ClockFreq) x CU_ratio_(in_use)

You should be able to see that Clock is a substitute for Potential difference, and CU_ratio represents current flowing – as is the case when more CUs are active, more current flows because more transistors are actively passing current from collector to emitter, rather than the collector & emitter acting like a tiny, tiny, capacitor plates (AFAIK).

Now, if we say the TDP is fixed at something like 150watts for the GPU, and for arguments sake the lightest workloads still use 18 of 36 CUs. So the Horizon map screen explanation needs maximum clock boosting to do a capillary effect to discharge inactive transistor through the CU transistors that are active, and in that scenario the equation would be as follows.

150 = GPU_factor x 2.235GHz x (18/36) and with some rearranging we get:

Clock_factor = 150 *(36 /18) /2.235 = 134.228

In a second scenario we were told that a 2% drop in clock (44.6Mhz less) saved 10% power draw when heavier CU loads were active. So if we guess a CU_ratio at 30/36 as sustain maximum, and if it was at 2235Mhz the power draw would be 150*1.1 = 165watts. But as the PS5 is staying at 150watts the would only boost 98% of 2.235GHz giving

150 = GPU_factor x (0.98*2.235) x (30/36)

GPU_Factor = 82.181

If we then said an unsustainable peak of 32 of 36 active CUs was possible, but a doubling of frequency drop was required – so 94% of 2.235GHz clock (2% for 30 CUs, 2x another 2% for 2 more CUs)

Gives another guestimated GPU_factor = 80.323 and with one final one from the GitHub leak at theoretical maximum 36 of 36 CUs fully working at 2GHz gives another

GPU_Factor = 75.000

From the 4 GPU_factors and the four CU_ratios a quick regression allowed me to generate 2 dummy graphs that should make it easier to visualise how Variable clocks work in keeping power draw static and delivering more effective processing capability in real Tflop terms as opposed theoretical unutilised flops. I've obviously had to make some big assumptions here and I suspect the real graphs work nicely all the way down to 1 of 36 CUs in use - unlike my 18 to 34 limitation. Anyway, If that isn't the general trend of what Mark Cerny meant, then I think I might need to just take him at its word and not worry about how it works.
 
Man that DualSense controller looks incredible. Like a futuristic android design.

I like how each generation Sony makes bold design changes. Only gen I didn’t dig design wise was PS3

I really dig the white/black/blue aesthetic. Looks so clean and high tech.

I also kinda dig the XSX as well for different reasons, even though it won’t fit well in my entertainment center

The controller is super-sexy. Can't wait to see the console in that black and white style. But please with colors on the buttons like in some of the mock-ups just posted.

Inside Xbox was a bit boring as usual, but I guess they wanted to get all that out of the way to show nex-gen stuff and IP's in their E3 replacement-event.

So exciting times for console gamers... only a delay can oversalt my soup now.

Report me for trolling ND/TLoU2 threads

Looks like Friday June 5th, 2020 could be the possible new release date for TLOU2. Ghost of Tsushima could be getting delayed then, IF this turns out to be the case.

Why go through all this bs and "indefinite" delay if its a week later? I could however see the release date being near the end of june or beginning of July when things calm down

I did what? I said what?

Erm...?

I haven’t said anything of the sort, ever?

What are you even on about? I asked for other insiders to be bullied...? Having spoken to several of them before AND after, I would love to know what the hell you are talking about?

Please, enlighten me?

This has actually annoyed me a bit because I have never once said anything of the sort calling to arms and asking people to bully others. I would be frog marched off here quicker than anything.

So I’m waiting for you to clarify your bullshit, thank you.

Edit: it’s now been 20 minutes, and you have failed to reply to my question, but have instead added an edit to your own post that I requested other people harass other insiders. So... show me the receipts?

He is so argumentative with everyone. It's super convenient he makes all these charges against you and then blocks you without backing any of it up. People seem to be getting anyway with anything at the moment.

Any chance the mics are used for their audiosystem to detect your position? Like home theatres do.
I think the mic is primary for that "ask Playstation" patent thing... a bit sceptical on that one, will turn it off.

Don't want my controller listening in all the time.
