Is it possible to measure the Xenos performance against a PC part? Or does the fact that they have different shader architectures, run with different operating systems, and system hardware, make a comparison too difficult?
Bob Feldstein: It really is difficult to measure the environments against each other. You would tend to write an app to run well in its intended environment. I would discourage trying to compare them in these manners. That being said, the console has certain...

Is the shader architecture unified at both the hardware and software level, or do programmers still write their pixel and vertex shaders in two different syntaxes and then throw them into the GPU that puts them in a unified shader pipeline?
Bob Feldstein: The programmer can use the superset of instructions for any data running through the shader. This allows the programmer to be creative and n...
Carmack points out that there could be diminishing returns with the next generation of consoles, thanks to the architecture of the hardware. Although the PS3's Cell processor is powerful, it's still a single-thread processor (unlike high-end PC processors). There's not much more technology can do to crank more speed out of a single-threaded processor. To make up for this deficiency, multiple processors are used: multithreading and parallelism is the way to go. But this isn't easy to do in gam...
Who could be better judges of hardware than the game developers themselves?
"It's a wonderful machine to work with. I never lied about my impression of the hardware. It's definitely software-friendly hardware. From a developer's perspective, it's exactly the kind of hardware you want to work with."
—Tomonobu Itagaki, leader of Team Ninja and creator of Ninja Gaiden® and the Dead or Alive® series, quoted at E3 2006.

If Developers don't tell you what you wish to believe...they must not know anything. lol....Typical Sony Logic. I have searched and searched the net for favorable comparissons for the ps3. And there is NONE. They all favor the 360. Sorry its not my fault. Don't blame the messenger if the message isn't what you want it to be. The Truth hurts sometimes.
Its not me. Its an article comparisson by IGN. Sorry if it shows you what you don't want to accept. I won't stand by and let Sony lie. The Truth will come out. You don't have to accept the facts. These are quotes from devlopers and IGN comparing. The fact is Sony ONLY fans. You are paying 200 extra dollars for a blu ray player. Thats it. Sorry.
You make the Ps3 sound so unrefined!
[Laughs.] Well, yeah, but the tragedy is that it is unrefined. There's a lot brute force in there - I'd be the last person to admit it, but the truth is that the 7800GTX is a pretty powerful piece of hardware, but it's not very elegant, it hasn't got the kind of: 'Well, how do we design this to be the best possible console we can build for this money?' Instead it's been put together at the end of quite a complicated process. We have two ver...
How do you think your work on the 360 measures up to PS3?
I take a fairly robust view on this. The Xbox 360 GPU is designed to be a console GPU - that's what we set out to produce when we started the collaboration with Microsoft; let's build a really powerful, really flexible kind of general purpose GPU which doesn't have performance cliffs where if you do certain things suddenly the performance crashes down by a factor of two or something like that; let's have things pretty p...
What do you think of the PS3's Cell architecture? How much harder is it for developers to write asymmetric multiprocessing code that will run on the PPE and the SPE's? How difficult will it be to port code that is tuned for the Cell over to the 360 while maintaining good performance? Do you think Sony made the architecture complex deliberately to make porting that way harder, or were they just trying to get maximum performance out of their system?
I don't think the Cell is as w...
Even ignoring the bandwidth limitations the PS3's GPU is not as powerful as the Xbox 360's GPU.
Below are the specs from Sony's press release regarding the PS3's GPU.
RSX GPU
550 MHz
Independent vertex/pixel shaders
51 billion dot products per second (total system performance)
300M transistors
136 "shader operations" per clock
The interesting ALU performance numbers are 51 bil...
CPU
The Xbox 360 processor was designed to give game developers the power that they actually need, in an easy to use form. The Cell processor has impressive streaming floating-point power that is of limited use for games.
The majority of game code is a mixture of integer, floating-point, and vector math, with lots of branches and random memory accesses. This code is best handled by a general purpose CPU with a cache, branch predictor, and vector unit.
The ...
With Sony's specs out, here is a comparitive analysis. What's the outcome?
by Douglass C. Perry of IGN
SUMMARY
Now that the Xbox 360 and PlayStation 3 specifications have been announced, it is possible to do a real world performance comparison of the two systems.
There are three critical performance aspects of a console:
Central Processing Unit (CPU) performance.
The Xbox 360 CPU architecture has three times the general purpose pr...
damn you are right on about that.....its a shame for real.
Gears is going to be great. And I'm curious about the ps3. Can it deliver? Will it? I have never said it will suck. I come to the ps3 side to get news on it. I won't say the games will be good either. Untill the ps3 starts showing gameplay I am just waiting and watching. I fell for the CG video stuff with the ps2 launch...lol...honestly...I did. But i'm older and smarter now. I need and want to see something amazing. We will see. But when people say...PS3 is better with no nothing t...
But the Japanese look at us as the big laughing stock. They know we don't have the same sense of pride that they have. Where has it gone? Where is the American Pride that use to be in the 50's and 60's? The whole world including Europe looks at us like we are stupid kids. I know this because I pay attention and don't lived wrapped up in my little world thinking everyone loves us. They don't. lol...But we should at least love ourselves. We should at least stand behind our own. Where i...
What country did you go to war for? USA? JAPAN? Ect? Because I see it as American Pride when gamers in the USA defend the xbox 360. I mean the Japanese do it over there. They have always felt that their tech is better than ours. Yeah they'll eat our food and buy our fashion trends but they really beleive they are smarter than us and make better tech than us. An american company made the DVD and get paid royalties over every dvd sold or made for games. The Japanese don't like that. Th...
He aint great until he wins the NBA championship. Until then he will just be Good. He just stands out on his team because Clevland built there team around him. Lebron is way overated by the media. He is Good. He ain't Great yet. When Kobe guards him he locks up and chokes. Same with when Tracy McGrady Guards him. In the playoffs he clearly traveled on two of his game winning shots. He is Good. Not Great. He may be Great one of these days.
you keep bringing up NCAA. It recieved a Good rating at the lowest and mostly Great and Outstanding ratings from many sites. It didn't recieve ONE ok or poor rating. When a game like that comes out for a new console for the first time they have to do everything from the ground up so most time is spent on getting the graphics engine and controls sharp. Then they add the extra's in the next installments. The reason why the xbox and ps2 versions had more to them as far as features go is bec...
No you are confusing Good with ok. lol...Good is Good. I never said good was great. lol....nice try. And Prey got Good reviews and Great reviews and Outstanding reviews. 7,8's, and 9's. So please stop with the hating. Ok. Good is Good. Great is Great. Ok is Ok. Got it? Good. And same with Chromohounds. It got Good ratings, and Great ratings. Its all a matter of the reviewers opinion and expectations. But Good reviews and Great reviews sounds like both games are Good and Great d...
When describing the Xenos GPU, it has been said that its capabilities go beyond the Shader Model 3.0, placing a plus symbol after the DirectX nomenclature. Can you give specific numbers (for example, the maximum number of shader instructions executed) that corroborate this Shader Model 3.0+ capacity?
Bob Feldstein: Among others impressive aspects, the Xbox 360 can execute 1000 instructions/programs, offers higher precision than required, and does shader exports. Also, as a uni...
