This man is the face of the PlayStation 4.

Prcko1966d ago (Edited 1966d ago )

true,every day 10 articles only about cerny and his master plan behind ps4
i don't say it's a bad thing

hakis861966d ago

:)Hehe a lot of funny pictures of him around the web!
He is cool though.

WooHooAlex1966d ago

Is it weird that I have a man-crush on Mark Cerny?

MikeMyers1966d ago

"This man is the face of the PlayStation 4."

As he should be. He is a game designer who had input in the design of the system. It looks as though Sony learned a lot from the PS3 and how they can improve things for game development.

Aery1966d ago

I think all real gamers "must" buy this console just as sign of appreciation for the effort of this guy.


PS4 is based on GCN 2: having 8 ACE's (AMD’s new Asynchronous Compute Engines), each capable of running 8 CL's each. Tahiti and 7970/7870 have two ACEs, 2 CL's per ACUs.

If I make that simple the ACUs are like the SPUs in the CELL which are efficient in heavy calculations operations and Cerny confirmed that they can mimic the behaviour of the SPUs with them which gives us 64 operations compared to 4 in a ATI 7970. That's the power of a GPGPU. It is a greta idea for Sony from shifting the CELL a processor doing graphical stuff to a GPU doing CPU stuff.

"PS4 Can Perform Asynchronous Complex Processes"

I am not surprised at Mark Cerny's enthusiasm. However to be honest its misplaced, i dont blame him after PS3 being restricted to a decade old tech for so long any upgrade is a relief, the mans constant articles show how desperate console developers had become in general, games can finally progress again.

Though really so many praising articles and yet PS4 is still limited to 30fps on most games, some supercharged PC that is lol.

Shad0wRunner1965d ago

Console games are never going to run at 60 FPS as standard. Even when developers start to be able to squeeze more out of the hardware, there is always going to be a trade-off. They can either put more pixels, shaders, lighting effects and other graphical elements on screen at once, or they can include less shiny graphics stuff and have it run at 60 FPS.

And shiny graphics stuff sells to a far larger audience than high framerates. "Look at this sweet explosion" and "Look at the detail of the facial animation" speaks to people. "Look at the framerate" doesn't. As long as it isn't choppy, people don't care whether it's running at 30 or 60. While there will always be exceptions, on the whole developers are always going to push for more graphical detail than a higher framerate.

TheLEGENDofTydo1965d ago


Your so wrong about the 30fps thing.
The PS3 wasn't even limited to 30fps, it was limited at 60.

The ps4 is limited to 120fps but nobody care about fps and if you do then you're just not a gamer. Battlefield at 60fps looks no better than Call of Duty at 30 fps. And even the games i have for my $3000 pc that play at 120fps look just as smooth as my ps3 does.

Cerny is awesome :D what a guy to represent the PlayStation brand. I like Andrew House too, mainly because he has the same beard style as mine :D

G20WLY1965d ago

Cerny is a cool nerd, affable too. He's done a great job, it seems, and deserves all this attention and credit.

I like House too - he's fluent in Japanese, I just find that so impressive! Nice to see one of us Westerners bothing to learn someone else's language for a change.

And I just want Jacky T to be my uncle, as he seems so nice! :D

this is all coming from a 50 minute speech he made (there is a vid)

all these articles is a bit silly tho

ZodTheRipper1966d ago

It's very worth watching from start to finish.

titletownrelo1966d ago

he's a great public speaker, very passionate and proud of the work he and his colleagues have accomplished.

Narutone661965d ago

"Make a console easy to develop for, but hard to master". That's really some motto to guide them on how PS4 was conceived.

1nsomniac1966d ago (Edited 1966d ago )

I think what he's trying to say is that all of this was explained in his 30 min conference video.

You could either watch the 30 min video or spend 3 hours reading all the articles that have been posted here quoting from it!

...Morale of the story - Watch the video, stop repeat posting the same articles!!

papashango1965d ago

so theres a million n4g article on mark cerny based off one presentation....

at what point can we start reporting as duclicate articles?

t0mmyb0y1965d ago (Edited 1965d ago )

Oh lol. Ya guess there have been a few.

GABRIEL10301966d ago

There are lot of articles based in the same presentation that Cerny did in Spain a few days ago. Cerny is a great person because is calm, centered, smart and he's a gamer and understands the needs of the players and developers. PS4 is an amazing device.

ZBlacktt1966d ago

SO this!!!!! Damn people go watch the video yourself of Marks event. It's like 50 mins long and a very good watch. All these stories of people taking very small parts just to make a story is sad. You are missing out on so much hearing it from the man himself. Go watch the video on youtube.

1OddWorld1965d ago

Wow watch the video. It shows what passion this man has for the gaming industry, and how he and his comrades are shaping the future of gaming by listening and learning.

Every gpu can do that, as gpu's can do multiple streams of data, while cpu's can only do one per thread.

However, its just not a good idea, as cpu's handle a lot more data per thread then a gpu can.
The gpu's in the ps4 and the xb1 are no different from the ones inside a pc.

Valkyre1966d ago

clearly sony made a huge mistake, they should fire that dumbass Cerny and hire mr. Foxgod.


Foxgod1966d ago (Edited 1966d ago )

Where did i say they made a mistake?
I said all gpu's can do it, not that its a mistake.

Its a feature that can be used when the cpu is bottlenecked, but that will never happen as its usually the gpu that gets bottlenecked.

SpecialK1966d ago


Its a bit different with consoles though, pc games have to work across many different specs which is why games never take full advantage of an individual PC.

Its different with consoles where they will do everything to max these things out. Its not uncommon for devs to use uncommon techniques and try out different things to really push a console.

Foxgod1966d ago

Understandable, but i cant see it happen, as you would have to sacrifice a significant amount of 3d processing, just to push the physics and AI a bit.

dantesparda1966d ago (Edited 1966d ago )

No, not all gpu's can do this, gpgpus can and even then there are limits, like most cant do general purpose computing while simultaneously doing graphics processing, whereas the the PS4's gpu can (its one of the mods done on it). And a feature that AMD is going to bring out to the PC soon

Pandamobile1966d ago

@Dantesprada True, not every GPU can, but every GPU since the 8800 cards (2006) have had GPGPU capabilities.

Every game that uses PhysX GPU accelerated physics does collisions, simulations, and world simulations (optional). GPU texture decompression is pretty common too. The only thing new here (I did some research and couldn't find much information on it) is the ray casting for audio, which sounds like an awesome piece of tech if they plan on using it for what I think they'll use it for.

BitbyDeath1965d ago (Edited 1965d ago )

Doesn't matter if PC could do it before or not. The games weren't taking advantage of the tech as they had to be made with the lowest common denominator in mind (ie the consoles)

Narutone661965d ago

@Foxgod, as Major Nelson would say "Are you a developer?" in a menacing way.

you forget foxgod that they have alot of custom software and programme which make much better use of every component

GABRIEL10301966d ago

The Ps4's CPU/GPU is integrated with a large bandwith, neither PC or Xbone have an integrated GPU.

Maybe in the near future the PC could be designed with this integration, but in the Xbone's case is unlikely.

Gameratheart1966d ago

Maybe I'm wrong here.... But the x1 is also doing the whole soc thing... In other words, it's cpu and gpu are all one chip.... Although maybe I'm wrong... I thought I read that it uses the all in one thing too....

Rhaigun1965d ago

It does. Just like many laptops use APU's as well.
Gabriel has no idea what he's talking about.

LNDCalling1965d ago

@Foxgod @Pandamobile

As already stated by @PLASTICA-MAN the customisations in the PS4's GPU make its GPU far better at these operations than an off-the-shelf PC GPU:-

- 8 ACE's each capable of running 8 CL's each.
- Additional bus providing a direct link to system memory that bypasses the GPU's caches.
- Enhanced L2 cache to better support simultaneous use by graphics and compute workloads.

PC GPU (7970 / Titan)
- 2 ACE's each capable of running 2 CL's each.

PS4 GPU admittedly behind on stream processors and ROPS but still holding its own for a console GPU!

On top of the above we are talking about a closed system and programing directed at same, no PCI bus limitations etc, therefore I can't see how this isn't something special as every GPU since the 8800 has had GPUGPU capabilities!

Ju1964d ago (Edited 1964d ago )

Those 64 compute channels will make a difference. This combined with a slim API which allows the PS4 efficiently "scheduling" compute tasks within the render pipeline plus a coherent memory sub-system is far beyond PCs. If anything it's simply a higher granularity to submit compute jobs efficiently. Sure, it won't make up for brute force core count, but we'll see some quite nice results in the coming years when developers will start taking full advantage of the architecture.

I thought the same thing as well. I've seen people who were married and turned gay. Maybe it's the way he moves on stage with the bent wrist?

Jaqen_Hghar1966d ago

combo of his voice and maneurisms but a man knew he was straight when he saw the wedding ring on his finger Feb 20th. At least a designer doesn't fiddle with his ring like Mr. House does on stage. A man could care less about his sexual preferences all a man knows is that he's an amazing smart man who could probably build a transformer or death star if he put his mind to it.

GABRIEL10301966d ago


25 years....well.... maybe he makes very happy at his wife...with a large.......the first impressions deceives.

Cerny is a genius, maybe like Jobs, a quiet guy with nice ideas.

Asynchronous complex processes? Dayummm!

It's probably just a flashy way of saying "multitasking", but if you only say "PS4 can do multitasking" it doesn't sound as cool. You gotta say "PS4 can accomplish elaborate multifaceted algorithms within an exceedingly accelerated time frame to ensure the optimal multi-leveled experience".

MysticStrummer1966d ago

"You gotta say "PS4 can accomplish elaborate multifaceted algorithms within an exceedingly accelerated time frame to ensure the optimal multi-leveled experience"."

I prefer "PS4 kicks ass"

Foxgod1966d ago (Edited 1966d ago )

Not entirely, multi tasking refers to running multiple application at a time.
Asynchronous complex processes refers to multiple data streams being processed that can be individual data streams from different processes going on inside one application

Multi tasking is a lot broader and cannot be applied to asynchronous processing, as this can only happen within an app.

Asynchronous processing can be perfectly done on cpu's these days however, considering cpu's these days have multiple threads.
Which is why i stated in another reply, that its just fancy talk.

XabiDaChosenOne1966d ago

Nobody is impressed bro, give it a break.

Nocando1966d ago

And these tards just lap it up, as if it's the only gpu on the planet that can do this.

Angeljuice1966d ago (Edited 1966d ago )

@Foxgod @ Nocando

The way the PS4 does it is completely different.

A conventional CPU writes to CPU memory, that data is then moved to the gpu's memory pool, the gpu processes the data and the processed data is stored on the gpu's memory pool whilst waiting to be moved back to the main memory again.

PS4 has a unified memory pool, both the CPU and GPU can access ALL the data directly. This isn't currently possible on any PC anywhere in the world.

PC: CPU> mem1> mem2> GPU> mem2> mem1> CPU

PS4: CPU> mem1> GPU> mem1> CPU

It is a much faster process and doesn't bottleneck the limited PCIe bandwidth as it would in a PC.

You learn something new everyday eh?

Don't worry Nocando, I won't call you a 'tard' for not knowing this, you simply don't know what you're talking about.

nukeitall1966d ago


actually what is impressive is you completely ignored what foxgod said and instead appeared ignorant.

What foxgod said is true and isn't intended to impress you. Nobody I know gets impressed by comments like that.

however we do get dissappointed by ignorant people all the time! it is what is f'in up mankind!

XabiDaChosenOne1966d ago

@nukeitall you again....he is trying to state the obvious by refering to how the PS4s GPU would work in a convetional PC when a console is CLEARLY a more optimized piece of tech. Read Angel juices comment and educate yourself.

more like a flashy way to say "GPGPU computation".

Ju1964d ago

They don't say "multitasking" because it really isn't. Multitasking requires context saving on a per "task" basis. Means, each "task" stores it's context. And this isn't supported. I once said it's "pseudo" HW threading of the GPU, because it allows you to schedule multiple jobs to the compute units, but the GPU won't save any states, etc. This isn't yet possible with the current architecture.
