“be manipulated to be incredibly good at something the cpu is specifically not very good at, and make the software aimed at the ppu. while a different set of software could indeed run very well on a cpu. its a suspicion, theres no way to prove or disprove it.”
It can be proven and disproved. Just do the math. Physics require tons of internal bandwidth something CPU’s don’t have enough off..
You can also prove it by all the developers who have said and show the CPU cannot do the work. There are tech demos from ATI, Nivida and even Intel that show how even quad cores cannot handle lots of physics at once. There is not one bit of evidence to say CPU’s can do it. If it was possible someone would have downloaded a SDK and made a tech demo showing it by now.
“as i've said before many many times, you don't need 100% accuracy to model a simple falling object, its overkill to take into account every minute detail because the end result will look almost identical”
That’s very true but even if you don’t use 100% accuracy and cut down as much as you can the CPU fails due to lack of internal bandwidth and not being able to processed data in parallel two things you need for physics. Being able to process data in parallel is the reason why GPU are so much better at CPU’s for physics.
Just look at the quad core tech demos from ATI and Intel and how the CPU alone slows right down rendering physic.
Go read the white papers on how physics work and you will see CPU’s are very inefficient and a bad choice for physics.
“give it time ageia should go bust soon.“
Yeah right. How can a company that’s doing very well with 100’s of game out that use there API and 100’s more due out go bust soon? Every trade show has Ageia packed with develops trying to get a look.
Just look at all the developrs who have dropped Havok for Ageia this year alone.
