Galego, I don't know what you want to prove here. Reading all this and the other threads, I get it: you like the PS4, even moreso because it is built around AMD parts. But your affliction for its success is blinding you from its potential to not meet expectations in reality.

If I was a casual gamer who wanted a no-fuss experience with gaming, I would drop money on the PS4. But I know the processing potential will still be below that of which a high-end computer can provide simply based on the fact that for say $400 so maybe actually $150-200 in the CPU+GPU department, I am not going to get a straight equivalent of a $2000 desktop and still fit within the power envelope of an average entertainment box. The other members will more or less agree that the PS4 is great in its own way but not the wonder machine marketing and enthusiastic individuals posit it to be. I'm looking forward to understanding how it works but it does no one any good to hype it beyond reason. If it does prove a hell lot of computational power, good—no one is worse off for having that. But as of now, no one is absolutely sure but as the wisdom of the crowd goes, the initial information is not absolutely supporting a PS4>PC claim.

Can developers really work and tweak future games to crank out great experiences due to the unchanging static nature of consoles? Yes, and that's the real benefit over time because one doesn't need to worry about upgrades and such. This essentially becomes a software development concern, not the hardware that is falsely seen as being almost limitless in power by the way you put it. I mentioned static because the PS4 will more or less be finalized now, going into production, and designed to last for several years; whereas I think rumors of the Nvidia 7-series are popping up and AMD certainly has things in the pipeline. What about all the improvements from Intel and AMD in the immediate future? DDR4, stacked ram, hUMA and those sort of concepts—these make the PC quite dynamic and sure, people spend more but they are also paying for forward strides several times a year of desired. The PS4 meanwhile remains the same until a shrink like the PS3 > PS3 Slim in a few years time that again will have to endure longevity.

The PS4 will look fine for people who like consoles. It'll take time for developers to work out the new platform and best optimize games to run on its set of constraints and limits. But when future games adapt this multi-threaded x86-like platform, the PC industry is not stagnant and merely waiting to flex its strengths. 8-core Jaguars will be topped by 8-core Steamroller or whatever you want to pick out in a honest comparison; the GPU will be surpassed sooner or later. The very nature of these two different markets makes the whole better-or-worse argument a bit pointless, especially right now with a bunch of speculation and vague unsupported numbers and references.

Can it be better than a PC? Sure, if the code is poorly optimized or gimped for one platform and not the other, but from the articles I see, games should port over to the PC nicely. We will find out later on when more details arise. There's no shame being wrong or incorrect but you are distorting facts and presenting false information to lurkers like me. Plenty of posters have tried to be patient with you in this and other threads and you have got to find a way to either reconcile with the fact that 1) these are just companies and things made, not lives at stake and 2) that we could all be wrong, including you.

In case you did not notice Mark Cerny has an interview where discusses several aspects of the PS4 with some tech. deep. He explicitly explains why the PS4 is a "supercharged PC". Interesting the part where presents part of the vision that they had for the next gen



how PC hardware could not support that vision and how the PS4 architecture was designed to address that problem.

http://www.gamasutra.com/view/feature/191007/

He is the systems architect for the PS4, he likely has to be positive about the system's architecture to the public in order to keep his job.

While the PS4 looks to be a (IMO) very good architecture for its design objectives, saying that "it is better than a PC" is a claim with not much concrete evidence.

by the time they can finally utilize the full power of the system it will be outdated anyway.

"I hope PS4 will change the development games have had since the previous console release.
Got tired of my PS3 "movie" colection, I'd like to see some better games for a change. "
-a post from that link
had to lol at the ps3 movie collection.

Same with my PC. Instead of optimizing anything we will just keep throwing money at it. Most games can't even utilize quad core chips from 4 years ago, better yet optimized for full performance potential.

PC is synonymous with Microsoft. If you simply meant the hardware, there's no doubt PC hardware is better. If you mean achievable performance with the DX11 API, there's the difference. There's a reason why source engine works so much faster on Linux.

Yes there's a difference, not 2.5x680 difference.

http://www.fpsgeneral.com/news/valve-software/21147-valve-source-engine-runs-faster-on-linux-vs
On Windows, the team ran Left 4 Dead 2 'on Windows 7 with Direct3D drivers' and were getting 270.6 frames per second (FPS) as their baseline.

On Linux, Valve was running a 32-bit version of Ubuntu (a Linux-based OS). Both machines were running the same hardware, which was:

Intel Core i7 3930k
NVIDIA GeForce GTX 680
32 GB RAM
Initially, Valve only came up with 6 FPS on Linux, which they point out is common when successfully porting to a new operating system. After making some tweaks and optimizing the game to run on Linux, the team ended up recording 315 FPS - a significantly better number when compared to Windows.

Interestingly the story did end there...

Even after a set of performance tweaks, the Windows edition still couldn't quite match Linux's speed.

http://www.escapistmagazine.com/new...urce-Engine-Runs-Better-on-Linux-Than-Windows

Ironically they don't mention the gains made and how close the gap actually was, of course that's to be expected in a PR spin.

However I haven't seen anything relative to what is being discussed. Did they free up draw calls allowing the gpu usage to go up? Was the gpu usage already maxed with boths systems and they just got more efficient code implemented on the linux system?

What's the bottleneck? They don't say, how can we use it in this discussion?

It's not mentioned what version of OpenGL Valve used either. It wouldn't exactly be a fair comparison if it's L4D2 DX9 vs OpenGL 4.2.
AFAIK, DX9 always had more overhead than OpenGL 2 anyway

The point was not Windows vs Linux performance. It was to show how much power of PC hardware is simply wasted due to poor optimalisation and gimped tools

So Linux a very low overhead operating system beats bloated windows by 10%. I'll give you that. So how does a ps4 overcome a 300% deficit in the hardware department when even Linux can only carve out a 10% difference? Simple answer: it can't.

^^ No. 315 FPS is a 16% more than 270.6 FPS, but here you are comparing a bloated API on a full OS with a bloated API on a full OS. Ubuntu 12 is one of the most bloated and slow linux distros available. Moreover they compared a 64bit Windows against a 32bit Ubuntu.

The console will use light API, light OS, and close-to-metal coding...

----------

Effectively, much of the 'theoretical' PC power is lost due to API overhead and unoptimized OS such as Windows. I already explained this point for days in another thread, which someone already linked here for me. Read the links with John Carmack stating how consoles can compete with gaming PCs that are from two up to ten times more powerful. Read Richard Huddy making similar claims...

I am going to cite here a developer who I did not quote in the other thread: Timothy Lottes (Nvidia). This is what he said just after the specifications of the PS4 were known:

The real reason to get excited about a PS4 is what Sony as a company does with the OS and system libraries as a platform, and what this enables 1st party studios to do, when they make PS4-only games. If PS4 has a real-time OS, with a libGCM style low level access to the GPU, then the PS4 1st party games will be years ahead of the PC simply because it opens up what is possible on the GPU. Note this won't happen right away on launch, but once developers tool up for the platform, this will be the case. As a PC guy who knows hardware to the metal, I spend most of my days in frustration knowing damn well what I could do with the hardware, but what I cannot do because Microsoft and IHVs wont provide low-level GPU access in PC APIs. One simple example, drawcalls on PC have easily 10x to 100x the overhead of a console with a libGCM style API.
It is easy to get:

A 200 HP superbike is much faster than a 200 HP supercar

A 2 TFLOP console is much faster than a 2 TFLOP gaming PC.

Isn't PS4 going to use Asus motherboards? Great hardware but if their software is used for fan control..... Most games will have to be designed to run in 512MB RAM, or less.... :D

16% is a far cry from the 300% figure you're tossing around.

It is easy to get:

A 200 HP superbike is much faster than a 200 HP supercar

A 2 TFLOP console is much faster than a 2 TFLOP gaming PC.

It is easy to get, except you're not comparing a console to an equally powerful computer. And enough with the car analogies. They don't work when you use them.

No idea on why you snip important parts from my posts...

As said in the part of my message that you snipped that 16% increase on performance is only the gain from going from a bloated API on a full Windows 7 PC to a bloated API on a full Ubuntu 12 PC.

The increase on performance is much greater when going from a bloated API on a full Windows 7 PC to a light API on a light OS with close-to-metal capabilities console.

It is easy to get, except you're not comparing a console to an equally powerful computer. And enough with the car analogies. They don't work when you use them.

I know it is easy but you fail to obtain it once again.

A 200 HP superbike is much faster than a 200 HP supercar and performs like a 600 HP supercar (approx.)

A 2 TFLOP console is much faster than a 2 TFLOP gaming PC and performs like a 6-8 TFLOP gaming pc (approx.)

Read Carmack, Richard Huddy, or Timothy Lottes stating how consoles can compete with gaming PCs that are from two up to ten times more powerful.

Read Quantum Dreams claiming how the power in the PS4 is like a gaming PC of 2014 or 2015.

Read Epic. Read Guerrila games...

Important part from your notes? That's funny, you have no notes, you have conjecture fueled by fanboyism and no data to back it up. Your data consists of "he said" and your own misinterpretations. Came back when you can prove your case. Rehashing nonsense is still nonsense.

Exactly. I'd love to see the actual proof behind his "facts". And claims from game developers counts about as much as a car salesman that's telling me how great this car is that he's trying to sell.

23 pages later:

The argument is still "consoles suck!" , "no, PCs suck!" back and forth forever. So unproductive.

If you don't like the numerous links in this thread, you can google it yourself.

Opinion: The PS4 will be better than the average gaming PC.
Fact: The PCI bus is significant bottleneck in PC gaming performance.
Fact: The PS4 eliminates this bottleneck.

There really isn't any point of contention you're making other than "burden of proof" which has been proven numerous times over.

I am a programmer and I've actually written programs in OpenGL. You'd be surprised at the hoops you have to jump through trying not to saturate that bus in order to get the most out of your GPU.

What proof? That there's more overhead on PC? That isn't being debated or argued against.
