The RSX shading power is amazing.
While Xenos can process 96 instructions/clock and it has to split it between vertex and shading, RSX has can process 120 instructions/clock just for shading and other 16 instructions for vertex ( SPEs can even come in help here), And it's even running at 50MHZ more than the Ati chip.

Yeah. That would be surprising if true.
This is going to be interesting. I think I'll wait for some nice long writeup. Especially, since DaveB has already questioned the veracity of the ATI numbers on that chart.
Alright. Funny this time it's Sony that gets a PC GPU with a few (and hopefully more than a few) new features, and MS that gets the truly new GPU architecture.sonycowboy said:
Edit: btw, what's with this horrible photoshop job?

That's most likely not the actual RSX chip, but rather something with the same name.

That shot is from a tech demo Nvidia showed at the Sony PC. How is it a photoshop?
I saw the RSX pictures at gamefront, didnt bother translating

Not really. The RSX can access both the XDR memory and the DDR3 memory independantly,and they are both "main memory" vs the 10MB DRAM essentially being a location where the 4xFSAA / stenciling is being performed. Xenos won't be accessing that memory to get textures / vertext information / etc.
Although, I think everyone here is aware of how powerful and what benefit the High Speed EDRAM has.

yup the same problem was present with the Nvidia CEO showed the demo. When the green plasma disappears they show a red plasma beam that lights up the creatures.
Basically:
The green plasma for the girl and her bodysuit
The red plasma (which is not shown here) is for the creatures.

Did you not watch the Sony E3 Press conference. This was a central RSX demonstration.

You didn't see that video from Sony conf did you? Watch it. It's *very* good looking stuff. That and Doc Ock demo were probably the best two pieces of realtime footage I've ever seen.

That's a rumor taken from B3D board. Pretty usubstantiated, as RSX is not even supposed to be taped out yet. Someone on B3 found that there's a series of completely unrelated chips that have that "daisychain" buzzword applied to them, and it seems more this is one of those chips.
I must have missed that, the streaming was really bad when I watched it the first time. I then downloaded the whole presentation but I did not watch it whole again.sonycowboy said:
Don't mind my comment then, but it really looks weird when you do not know what's happening
So,
RSX is limited with 'only' 24 ALUS for pixel ops, while Xenos could (in theory) use all 48.
But those numbers say RSX 648flops/clock. Even going full tilt, Xenos can do 480. And that still leaves 8 ALUs free for RSX to do vertex calculations.
Take the split RSX has 1-3, apply to Xenos, you have 12 ALUs doing vertex, 36 doing pixel shading. Now the numbers are 648 RSX, 360 Xenos. Big difference.
Vertex numbers: 80flops /clock RSX, same 480flops/clock Xenos. Lots more if you do vertex only, but I don't know if thats a likely scenario. Plus PS3 has CELL backup for vertices.
So it seems RSX has significantly more shading power than Xenos.

However, some of RSX will be spent doing 4xFSAA and some stenciling work that can be passed of of the main CPU in Xenos.
Hopefully, we'll get some nice comparison writeup from a source that "most" will accept, although I doubt such a person exists. Apparently, many consider EPIC to be "bought" by NVidia, and we certainly can't trust either NVidia or ATI (although people on both sides would love to).
this chart seems like bullshit..
it seems they took some rsx numbers and "downclocked" them to g70.
for example: 550/430 = 1.2790697674418604651162790697674
however when you do 51.6 (instructions/second on g70) * 1.279... you get EXACTLY 66, no trailing digits or anything. So most likely they took 66 and divided by 1.279...
and same goes for 103.2 (since it is 2*51.6)
It seems to be someone just did some math from the PS3 specs, assumed G70 == RSX and made that chart, with bullshit R500 (which doesn't exist) specs added.

Wow Microsoft got a raw deal. They get a GPU that's less powerful than ATI's next cards core. But magically nVidia delivered a more powerful GPU for the PS3 than their next cards core. :lol

There are so many illogical obstacles in what you said there that I don't know from where to begin. Seriously, just look at what you wrote and think about it.
i dont understand.
from this benchmark, it seems RSX will do circiles around xenos.. how did ATI say that their card is better than Nvidia couple of days ago in the inteview in gamespot.com
?????
is this article vaild ??? i mean, is it offical RSX numbers or someone made them while he was shitting in the bathroom ?

Thinks his PR is better than yours.
I knew it!! I knew it was just a G70 modded to PS3 inputs. So long ago, nobody believed me.... They didn't state RSX stats because it would have compromised the G70 launch and fundamentally given ATi free spec sheets months early. But now that G70 is officially launched, RSX is as well.....
I love though, on those charts how they use top of the line NV parts, but compare it to an X800XL...... Scared much???? Put it up against the X850 XT PE, for an exen comparison.
Also for those of you thinking it'll blow away the Xenos, take into fact the efficiency of the unified pipes. Xenos will be more likely to hit it's theoreticals than RSX will. As well as the 4xAA hit RSX will take as well, if they decide to employ AA at all. Basically XBox 360 is coming out 6 months in advance and will hold it's own pretty damn good, I can even say you'll probably see no difference in games.

Tonight we'll have a lot of reviews and benchmarks of G70 cards.
As for Ati comments,what do you expect them to say?
RSX on paper is much more powerful than Xenos in terms of shading which is a very important thing for next gen games.
Now it's all about games using this and Cell's power.
These benchmark comparisons are from Nvidia. That says it all. All info seems to point to Xenos > RSX but with such a radically different architecture in Xenos, its easy to make it look inferior. Hell, Xenos (technically) only has 3 piplines...lets compare that to RSX's 24 (or more) piplines....Xenos is teh sucks!
