Thats the point, if u want something different and unique u have to pay money and work hard, it may come as a surprise to u but most great game makers care about the games more than the profit.

 

 

Well that is new to me: the video gaming industry which generates more money than movies btw... is about .. ART ? Not money ?

On your remark about the """"outdated UR3""": We are not talking about fundamental science here.... iterative development are the best way to obtain a good results. Making a new big bang from scratch is expensive and generally not worth the investment, if you cannot recycle it later.

 

 

The videogame industry doesnt even come close to generating the same revenue as movies.

In fact they even lose to music.

Yeah, 165 million transistors, 1MB of cache and 3 cores are indeed very similar to 300 million transistors, 2,5MB of cache and 9 cores. That's why everybody uses X360 as cluster supercomputers like PS3.

No seriously, at its very best the X360's CPU is 3,2 GHz x 8 FLOPS/clock cycle (as any IBM PPE) x 3 cores = 76,2 GFLOPS of peak performance.

PS3 has nine cores (1 PPE, 8 SPEs) at 3.2 GHz which means 230,4 GFLOPS of peak performance or 179,2 in-game processing power avaliable.

Oh and btw the RSX is also a bit stronger than the Xenos (4 alus x 2 madds x 24 pipelines + 5 alus x 8 pipelines x 550 MHz = 255 GFLOPS verse 5 alus x 48 pipelines x 500 MHz = 240 GFLOPS)

X360 multiplats look better most of time because X360 has more memory avaliable (more memory = bigger textures and frame buffer) and PS3 is harder to work. Plus most PS3 multiplats do not even work with the whole Cell at all (only its single general purpose core).

Your haterboxes.

XCPU has 3 cores and CELL has 1 core, let me repeat that ONE.

 

SPE`s are NOT cores.

 

If you dont know what you are talking about its better to not say anything at all.

Funny thing is, with all this hate going on in these threads, I have yet to see a PS3 game that trounces all 360 games in every aspect of performance, ditto for a 360 game.

To some people "trounces" could mean 20% better.  To others people "trounces" is basically an unreachable sliding bar that constantly changes based on whatever the top performing game is.

The reality of it is that Killzone 2 "trounces" ALL games before it except Crysis.  KZ2 "trounces" Crysis in SOME areas (animations, character models, characters on screen, gun models, particle physics, 7.1 discrete audio, etc) but is close in other areas and gets beat in other areas.  Killzone 2 uses the SPEs to achieve up to a 40% increase in GPU performance (WAY beyond the X360)!

 

Also, Shippy is only speaking of the part HE designed (the PPE of the Cell and the XeCPU cores of Xenon).  That's actually a good benchmark to use.  We know that in most cases of optimized code, the SPE can be around 3x faster than the PPE.

One guy said said something that was incorrect about the BD drive speed in the PS3 vs. DVD drive speed in the X360. Even though the X360 drive is a 12x DVD drive, it maxes out at 8x for DL-DVDs (almost ALL X360 games).  The X360 drive has to build up to that speed over the span of the disc.  The BD drive has a constant read speed across the entire disc.  This ends in the BD drive being just over 1MB/s faster than the DVD drive in the X360.

That was just for the people interested in learning.  The others will do what they do best (try to discredit these unversities' real world implementations and me).

Wow, so not only does K2 trounce Crysis in a lot of areas according to you at only 40% utilization you also claim the examples you gave are REALWORLD examples instead of sterile tests?

@haxxiy: Where did you get the data on the number of transistors on each CPU?

Of course these claims should be read with a critical mind. The Cell is different from 360's CPU in several ways, it has more cores and is much better for many kinds of scientific applications. Maybe he was talking about it from a game performance perspective.

 

 

 

Cell has less cores.

Last time I checked one was less then three.

SPE`s do not a core make.

Lets see best graphics on console
Metal Gear Solid 4, Killzone 2, Uncharted 2 , GOW 3 , Heavy Rain (All unique engines)

so i don't get it if xbox360 is FAIRLY close to ps3 but easier to program for, and yet its biggest achievement is games using the out dated UR3 engine...hmm....what?

I know it's easy to over look, but it's storage. Yes the DVD transfer rate maybe higher than say BR, but the qaulity of texture can be a lot better. There are factors to take into account. 360 can make textures look better than PS3, but the PS3 can have hands down better textures.

It seems strange, but after a certain res. You won't notice the difference as much. The CPU only process vector math and by the IBM designer claims both systems will make little relevance to gap. What is prized in graphics is texture fill and processing not vector math. So when you see the questioned "better" looking games what you are mostly looking at is the games textures.

so
360 = texture effects
PS3 = better textures

appealing hardcore definition of better graphics = texture qaulity

So yes a game that is designed from the ground up for the PS3 will likely support and use higher textures. While multi plat games will in all likely hood use the same textures. The fact that PS3 fans get miffed that multi games don't look much better if at all on the PS3 just proves this.

 

 You have to explain this one to me please.

The 360 has more memory theoretically available for textures then the PS3 does so how can the PS3 have better textures?

 

Texture resolution and quality is determined by available memory on the graphics card size and the capabilities of said graphics card.     The 360 in that regard is better equiped then the PS3 so please tell how you come to your conclusion.

 Here you get about PS3, both CPU and GPU (which stands fairly equal at 300 million).

 And here about the X360's CPU.

 

 

The anantech article is both wrong on a few accounts and outdated on a few others.

Actually reading it makes that painfully clear.

What kind of BS is this?!?!

If you don't know many multiplat games on PS3 are with lower textures then 360 version, cos of PS3 GPU, RAM and bandwidth. Yes you can have higher and more textures on BR disk, but what is the point if you can't load them.

No one needs to read past your ignorant 9 core statement to know that you don't even have the slightest clue as to what you're talking about.  How about doing some research on the Cell before spewing out number some idiot post on the official PlayStation forums.  SPEs are not cores and they most certainly don't all run at 3.2 ghz the Cell is an asynchronous processor.  If your ignorance was any greater you would choke and die on it.  Multiplats look better on the 360 because the system was designed as a gaming platform first and formost and was build with developers wishes in mind.

Cell's claimed advantage is on streaming floating point work which is done on its seven DSP processors and is x2 of what 360 CPU can do, but Xbox 360's CPU has x3 general purpose processing power.

BTW 360 GPU totals 332 million transistors
