what do you not understand of the fact that I'm talking of 2000-4000 (two-four thousand, impress in you mind this numbers) ragdolls
try to do some math
I'm a coder too by 22 years ago, in different field, do you need my curriculum to understand what I'm saying?
a) 2000 to 4000 animated, each with AI models on a screen that fights and reacts to physics forces
b) 100 simple, gourauded, plain, static, rigid ducks on a screen
and I remember that there're two cells in the machine used for the demos, one does rendering, the other physic simulation
Not at all. Demos are there as eyecandy too. It's a matter of showmanship.
easy time
there's no eyecandy
the render is pathetic, the iq is pathetic, where's the eyecandy of the ducks?
I hope that you're just jokin'
If they could have added 1 trillion ducks, you wouldn't have been able to see anything.
then, instead to make 1 trillion of trillion of fantastillion of duck in a simple demo, why don't make 4000 animated ducks in a lake that react to ambience and one to each other?
I
think to know the answer, you don't?
There's the duck to tie in with the PS2's demo. Then there's more ducks. Then there's lots more ducks.
here I've thought "PlayStation 2.5 here"
Well first of all I don't know what you were playing in 1999/2000,
a PS2?
but if you think any old CPU can software render like that...maybe you haven't even watched the demo?
you seems confused
I'm talking of the ghouraud rendering, and I've say "PS 1", but you undestand "software render"
read slowly please
But more importantly...
...I now appreciate where you're coming from. You're original statement that demos aren't a fair way to showcase technology has changed into an argument that Cell was supposed to be a super amazing hypercomputer and it's fallen far short of your expectations. Which isn't the point of this thread. This crazy statement without any explanation of your reasoning...
...also doesn't belong in this thread.
the thread topic is "ps3 to do real face morphing", but you're talking of physics and duck demos,
who is off topic, friend?
are you really confused eh?
you said that PS3 can't do rendering, physics and 100's of ducks at the same time, but the duck demo shows this.
again, you are getting confusion on confusion
you say that RSX is not available yet, but you say that the duck demo shows that PS3 can do this
PS3 without rsx?
hey, are you there, friends?
you're saying a lot of senseless things, the PS3 demo of E3 runs on a dual-cell computer
Well for starters how are they going to demonstrate RSX working when RSX isn't available yet? They wanted to showcase what they're new CPU is capable of doing. For real-world efficiencies we've got a few IBM papers and Toshiba realworld demos and we've got some working game demos running in realtime. Not a lot of info, but some nonetheless. And also, the whole point of this thread was a TOSHIBA demo of Cell, which you were saying was worthless as indicative of what the CPU can do, despite the fact the demo was exactly what the Cell was doing in realtime in a real-world software application. Why is a TOSHIBA demo of Cell worthless if it hasn't got FlexIO running and 7.1 audio encoding and AI? Why is a Toshiba demo worthless of what Cell is capable for Toshiba's plans for the chip just because it isn't a game?
Yes, Toshiba are only interested in showing the power of Cell because they aren't selling PS3s. And do you REALLY think they should go to a consumer electronics expo with a dull as dirt collection of numerical Prime Bench stats? How much attention will that get? And does Prime Bench properly benchmark a CPU's capabilities in the areas Cell was primarily designed, like stream processing FP data?
so first you say that the demo shows what a ps3 can do, and now you say that "it is only a toshiba Cell demo" (another thing false, it is a sony demo)
Yes. I'm biased against people starting a sensible discussion on one point only really with a different agenda. Your problem isn't the showcasing of demo's being unindicative of performance, but that you don't believe Cell offers any real tangible benefits over other solutions. The fact you believe a Celeron 500 can handle the LOD demo's physics shows you don't appreciate the calculations involved and are therefore in no real position to judge how much these demo's really showcase CPU performance.
my thoughts are clear, I don't need transaltion, thanks
I say that the duck demo is pathetic
and I've a LOT of doubts on Cell efficiency (Apple agrees with me, seems)
after all you have to remeber few heavy points (look at the datasheets)
1) Cell is provided with only 512 KB of cache
2) spe can't reach directly the main memory (they works well when a spe fetch the next one, as in multimedia processing, but very bad in the others fields)
3) Cell has an hit of 90% processing integers
4) Cell has an hit of 90% processing double precision numbers
5) Cell is an in-order cpu
6) Cell has only 1 PPE for general purpose computing
this are facts, if know a bit of the cpu arch. you can ready undestand why what I can see is a cpu that can do great thing on a videocam, on a HD-DVD / BR player, on a phone of last gen, and so on
but a very bad and inefficient solution for general computing (PC, servers, ask to apple if you don't believe), and a bad cpu for a console
the only, the ONLY thing that can save Cell on a console is using the spe to process dinamically vertex data on textures and fetch the gpu with a constant stream
but here comes the problem that I was talking
Cell have to do sound processing, AI, physics, game code processing, vertex
how can the poor spe do all this if they can't reach directly the sys mem??
you think that a little 512 KB of cache can be enought to store all the data requested to the spe?
512KB that are used by PPe too
I don't think that a thing as is this can do wonder, IMO It can do very bad
don't forget that apple have discarded the Cell Project just because of the dissapointing for performances........
