Platform Comparison - PS3 Vs Xbox 360 GPU Specs

[cliffbo]

Bloodmask, 15/12/2007 - The fill rate on the PS3 is significantly slower than on the 360, meaning that games either have to run at lower resolution or use simpler shader effects to achieve the same performance. Additionally, the shader processing on the ps3 is significantly slower than on the 360, which means that a normal map takes more fill rate to draw on the ps3 than it does on the 360.

This is one of the reasons why multi-platform games often times appear washed out on the PS3 when compared to their 360 counterparts. That is why when a game is coded on the 360 first and then "ported" to the PS3 the results aren't very impressive. But if games are coded on the PS3 first there is minimal or no difference.

Basicly when games producers are coding on the PS3. They are coding for the lowest common denominator. This is exactly how things were last generation with the Xbox receiving ports from the underpowered PS2.

It is basicly common sense. You can't "downport" things from the more powerful hardware(Xbox 360) to the weaker hardware(PS3). Sony may have claimed that the PS3 was more powerful but the results seem to speak for themselves.

Let's look at the maximum theoretical numbers for the Xbox 360 and PS3 GPUs.



Triangle Setup
Xbox 360 - 500 Million Triangles/sec
PS3 - 250 Million Triangles/sec

PS3 - 20.8 GB/sec (shared with other graphics data: textures and vertices)
PS3 - 10.8 GB/sec (with 10.0 GB/sec subtracted for textures and vertices)
PS3 - 8.4 GB/sec (with 12.4 GB/sec subtracted for textures and vertices)

Texture/Vertex Memory Bandwidth
Xbox 360 - 22.4 GB/sec (shared with CPU)
Xbox 360 - 14.4 GB/sec (with 8.0 GB/sec subtracted for CPU)
Xbox 360 - 12.4 GB/sec (with 10.0 GB/sec subtracted for CPU)
PS3 - 20.8 GB/sec (shared with frame buffer)
PS3 - 10.8 GB/sec (with 10.0 GB/sec subtracted for frame buffer)
PS3 - 8.4 GB/sec (with 12.4 GB/sec subtracted for frame buffer)

Shader Model
Xbox 360 - Shader Model 3.0+ / Unified Shader Architecture
PS3 - Shader Model 3.0 / Discrete Shader Architecture

Xbox 360 has the advantage in most cases.

This is very old and has been done and redone time and time again.

[masteratt]

PS3 GPU am cry.
And why did you post this cliffbo?

Soooooo 2005.

[VG Aficionado]

Wow cliff, did you even look at that page? It has a "Playstation3 bashing time banner" making fun of Kutaragi's accent, FFS. Just look at the site's name.

Not only those specs are mostly speculation (the full final RSX specs are not known) actually coming from a very old pro-Xbox 360 article, but you only need to look at the source and the way it's written to see that this "comparison" is biased and meant to downplay the PS3 and provide a FUDdy explanation for inferior ports.

There are multiplatform games like Burnout Paradise and Devil May Cry 4 which run at a solid framerate on PS3 and have screen tearing and slowdowns on the 360.

Uncharted and Gran Turismo 5 look better than most if not all the games on the 360 library.Heh, good points. Not bad for such an inferior GPU.

Please read what you're posting next time :locked:

Seriously cliffbo. At this point why'd you even post this. what the hell?

[Colin™]

ugh, cliffbo. Now its gotten sad.

[masteratt]

Hi I'm a dancer.

And my favourite dance to perform in this thread is what I call: Steel yet warm.

:locked:

Thank you, thank you very much.

[TrueVCU]

I declare open season on cliffbo.

now send this to the madhouse where it belongs.

[haunted leg]

the ps3 can also grill a hearty meal. so i ask you, who is the real winner?

[masteratt]

PS3 grill jokes?

Now it REALLY feels like 2005.

[haunted leg]

when in rome.

[masteratt]

.......mmmmkay.

[haunted leg]

i thought a comment about my ps3 being an excellent static dusting machine would be taken the wrong way.

[masteratt]

Hey lets have a fluid conversation next time where i don't get confused.

back on topic: there are rumours the PS3 can draw better squares than the X360 although X360 can make triangles look more triangular.

[haunted leg]

i still say the console i can use to bash in the head of my enemies with its massive heft, solid design and pointy corners is the clear winner.

[masteratt]

well i WAS going to go to sleep but I heard your cry for an encore.

Here it is again......Steel but warm

:locked:

Phew, thank you.
Thank you very much.

You can look for my dance performance in most cliffbo threads.

[haunted leg]

i'm not quite sure what you're trying to say masteratt.

[masteratt]

Then you should be a mod.

[TrueVCU]

Then you should be a god.

Come to think of it I too should be a god given the monumental amount of restraint I'm exercising in not posting the Omelet360 video.

[masteratt]

Wow I can't believe I'm still doing the edit quote thing.

[Xerxes]

In the end who cares the 360 will have slightly better graphics than the PS3 and the PS3 will have more superior CPU. In the end its all about what game suits you, not which one can draw more shapes than the other. I have PS3 so I can play franchises I grew up with Final Fantasy, Kingdom Hearts, Ico, Dark Cloud, etc. My cousin bought a 360 for the same reason. Do not fret on the trivial things and play games because they are fun like the majority of people who bought their console of choice. There is no need to turn this into a debate about what less than 1 percent of gamers care about.

^hahaha irl.

And man, this thread really lost it now.

[haunted leg]

that's what i saw when i first looked at xerxes' post. it just looked like a pile of videogame words that my brain couldn't put into sentences.

[Mr. Coww]

So basicly both render the game worlds better then the REAL world? My room is only 8 bit color...

[masteratt]

lol yeah, that's why it was hilarious.
Your parody felt real instead of for the sake of it.

This is where I usually put the topic back on track but......:shrug:
Okay I'll whine about the current forum speed instead: It's fucking slow.

[VG Aficionado]

I'll have a Phantom. Thank you.

[TrueVCU]

I thought it was one of the laws of the internets that we were never to speak of the abortion some call the phantom

[VG Aficionado]

OK then. Hmmm... I'll have a Sorny 3DO.

[cpiasminc]

Oh, boy... someone combined quotes from various other postings and made something of a mishmash. The first paragraph came straight out of the Harmonix guy's post. Although there's a bunch of pointless rehash, the big thing that really makes me wonder what the hell the guy was thinking (referring to Jbooth here) is this part...

Additionally, the shader processing on the ps3 is significantly slower than on the 360, which means that a normal map takes more fill rate to draw on the ps3 than it does on the 360.
If we're talking vertices, then the first part is true, but that has nothing to do with fillrate and never has, and if we're talking pixels then no part of this is true. Never mind that the pixel processing power on PS3 is typically greater -- it can be limited by external slowdowns, but that would be true no matter how much power you had -- shader processing has been divorced from ROP processing for ages. Long before the term GPU was even coined. There is no connection whatsoever between shader performance and fillrate consumption on ANY GPU.

[haunted leg]

finally someone understands where i stand on the console wars.

[D3adcell]

Anyone who cares about tech stuff, should really not be a gamer. In the end its about what you enjoy more. Which has the most enjoyable games. Nintendo hasn't released information on the Wii's specs and look at how its selling. You know why? Because nobody gives a fuck about the specs, they just want to have fun.

So really people need to stfu about this stuff and just enjoy their respective consoles.
