Gigabyte's single-card SLI

Quote (Darius Greywind @ Feb. 13 2005, 1:05 am)nVidia develops all the drivers for their chips now. Gigabyte can only use the ones they supply. They're paranoid about giving out any sort of details on how their chips work these days. This is annoying if you're using Linux, since nVidia's drivers dont work with most Linux installs properly.
There's no actual difference between putting both cores on one card, as far as the system is concerned. The link is exactly the same as using their cable to connect two regular 6600's.
not at all
if you have 2 6600 cards togheter, they have let's say 256 MB each one..
so using both you have 512 MB..
while using a single card, its harder to fit 512 MB in one bang..
also the distance is diferent...
voltaje is diferent too
while it uses 1 pci express to deliver the data to the cpu
the other uses 2 pci express.
same with power... if it has 2 cpus in the same card, that means it needs a monster powersupply cable ( 3 cables at least? remember 6800s need 2 cables each one )
not to mention how hot the dual cpu card will get.. o_O
and I seriusly agree with you on the nvidia thing....
getting the drivers hidden wont help them, they're seriusly making the same mistakes as 3dfx.....
who needs a monster chip that eats exesive ammount of power, its noisy, its HUGE and eats a lot of space in your computer, plus it only has at most.. 15% more horsepower than the competitor's flagship ( if not way less )
I prefer the efficiency rather than top end "cute alien tech"

Actually...
nVidia's SLI only uses the frame buffer of one card. So two 128mb 6600's means only 128mb of frame buffer. And that doesnt change either with Gigabyte's card. Yes, wasteful, isnt it?
And two cards in SLI use one x8 PCI-E channel each. Gigabyte's card uses x16 from one slot total. PCI-E can split up like that, which is cool in some ways.

booo, then they're not fully exploiting the total power of both cards or both cpus.... o_O
now I know why a 2x SLI 6800 cards didnt had almost 2X performance on games.. but only 80% more of horsepower..
