Tom's Hardware Take On Physics Cards

[EDIT: The forum keeps adding a space into the URL when I post it... to get the link to work, either copy & paste the URL and remove the space between "/03" and "the_", or just go thru the search result below:]

This isn't greatly detailed, but they talk to some physicists about physics cards. To summarize, it may come down to multi-core CPUs solving exact matrix equations vs PPUs doing approximate finite-differences methods. They suggest that there might be some compromise, like PPUs handling rigid body physics for tons of rigid objects flying around, and better CPUs calculating the more complicated stuff. Another point to take away is that good physics simulaton algorithms are still very much in development, so it might be unwise to buy a PPU that is locked into today's algorithms.

Hmm, I guess Tom's doesn't like external linking. It works if you click the link, then copy & paste the link into the browser after visiting Tom's.

 

Or alternatively, you can search for:

 

Scientists' Opinions on Gaming Physics

 

[EDIT: NEvermind, it actually seems the forum keep adding a space between "2006/08/03/" and "the_" when I post the URL, might be a security thing.

 

Yeah, I can post

 

"3/the_scientists_opinions_on_gaming" without a space being added, but

 

"3/the_scientists_opinions_on_gaming_physic

s" inserts a space between "3/" and "the"

 

Anyway, top post edite with a link that's one step removed, but works.

Now it worked. Thanks. Quite interesting, but it doesn't really say THAT much. It said at least as much that I know now that I wont buy that card for some time.
