It states that the PPU will require a 4pin molex connector :roll:
Geez, I;ve got a antec noehe 550, so that means I will need to get another psu??
My dfi mobo requires at least an 8-pin moles for power, and now I've got no molex connectors left...

I know but talk about worst case scenario. Expensive and runs slower, not exactly the best start.



i don't know about anyone else, but i never thought phsyx would make my system faster, just make things look better.....

ye ye, calling people with no common sense idiots isn't really a crime. i'm a perfectly reasonable person when dealing with reasonable people. unfortunately and you would know this as you are the same, some people don't give anything in an argument but if you do they claim a victory or something similar. so i just don't give an inch. the minute other people will admit there is a flaw in their reasoning i would do the same if i thought some valid points had been raised.

you get what you give in this life and some people should realise that.



Blah blah blah blah blah. Like I said before, as long as you can hide behind the safety of your keyboard and screen you will call people idiots just like the big bad ass E thug you are. :roll:

No, no crazy chemicals, but I did stumble upon some cool surfactants for cleaning glass Smile ... Pascal was one of my first languages (novice skills that is), I used Borland Turbo Pascal to program all our lab data acquisition software, then dabbled in C++ for a very simple laser/mirror aligning control software using a 3 port stepper control box.

Nice to see you mixing it up on the forums again....

Care and goodwill...

Pascal while being very easy is one of the best languages to learn memory constructs like links lists, stacks, circle link lists, and the alike. I love C++ but the Dean, being the best at C++, gets that job.

Good to hear from you again as well.

I feel I'm joining in kinda late into the discussion, but nevertheless....

There must have been another reason for these guys to introduce a separate physics calculation device such as this one. Apart from being useful in games it could, as many others previously have stated, be used as a co-processor in heavy rendering-applications. While it's true that multi-processors are a thing that's becoming standard, I would like to believe that the PPU, being a really fascinating piece of hardware, could be unleashed into it's true potential once it's incorporated into GFX-cards.

Think about it. A couple of years back the math processing unit (also known as the FPU) was not nearly as integrated as it is in today's CPU. It came as a separate chip, initially on a separate board even. So my point is, maybe this physics processor is about to go the same path as yesterday's math processors and eventually end up on the very same GFX chip?



Although not really into this GPU/PPU debate, I tend to agree: Sooner or later, either as separate parts or as a GPU's intrinsec functionality, dedicated physics processing will become a pervasive factor, in my opinion. Gaming aside (a big piece of the whole cake, though), high-end workstations will take full advantage of that capability, whether turning special-effects more especial, whether by providing more realistic simulations, like molecular dynamics, weather modeling, and all sorts of physics tasks actually done by powerful workstations. This, of course, only makes sense if the overall processing/storage/interconnect also scale up, performance wise. After all, it's about Physics processing, not just more "eye-candy".


Cheers!

eah, this is the extent of my programming knowledge, I took 1 semester of Comp Sci in college, Pascal based, did some novice programming using Turbo Pascal in DOS Smile ... a little VB here and there. Linked lists was about as complex as I go, pointer's helped me understand how the stack was organized.

Programming seems, at face value, pretty simple... just spell out what you want the computer to do.... but exponentially rises to incredible levels of complexity very quickly.

The PPU ultimately will be a winner, it's just gonna take some optimizations I would suspect.

Microsoft promises an API for PPU's in DX10 so good games should arrive for the PPU in 6 months.

Wish I had time for some game programming.

weird it ran slower, interview at E3 was rated like 3/10 "Bad" n when i watched it, was pretty horrible.

The game was released then the agea PPU was incorperated into it, the games at fault NOT the chip, have a look on the agea site its flawless

The main problem of the PPU is that it is using accurate floating point calculations whilst software based physics takes a lot of shortcuts. It is like comparing integer based maths with floating point based maths.

It is slow and does add to the games entertainment value. Ageia must make the PPU run at least as fast as current software based shortcuts used in games.

However, if in the future the PPU offloads CPU cycles and lets the CPU and GPU do more interesting things I am all for it.

For now, now way.

However Ageia is using the tests as advertising and saying, hey we got a PPU, come to use for specs.

I am sure when big companies and consumers think of PPUs the Ageia name will pop up.

Id say we need to wait until REAL GAMES who are built with the Physix api are programmed, since Im preety sure Aegia tried his best for current game developers to "patch" their engine to "work" with Aegia's PPU.
Its like triying to play doom II with your Conroe.
I doubt it will work correctly :P

:D I guess Spud would offer you a SDK for free... :D

I understand your point, though.

In a way MS will but I think they'll also use DX10 to force us to buy Vista.
On a off note, PhyX cards could make for an interesting upgrade path for low in systems. The % increase in the slower system test showed a bigger gain.

Actually Doom II will work fine with the Conroe on Windows XP. :?
