I didn't know that, did you...

I guess I've been using nvidia far too long...

What particular relationship or fact are you referring to?

 

[blanketyblank]

What are you referring to?
If you mean ATI cards being able to run at different speeds in CF, then yes I knew that.
There have been plenty of reviews of hybrid CF and such so it should be fairly well known that the cards will not clock down, but will use both cards at whatever speeds.
A lot of the time this means you'll get something in between, but sometimes you could get performance below having 2 of the slower cards(maybe driver issue).

Yea I knew that. I was going to crossfire my 5750 with a 5770 with different clocks.

That's what I was referring to which I didn't know. One of my 5870 is a dog and the other overclocks like mad so now I can set them up accordingly...

I'm not much of a fan of multi GPU rendering and never was for several reasons, but ATi seems to be a good bit ahead of nVidia in things especially in the last few years, and nVidia seems to have the notion that if they just factory overclock their chips and make them take more power than anything else in the world to keep up with ATi that's quite OK... I actually have recently bought a GTS250 for my main gaming box, so I am no fangirl of either company, but this is just what the situation seems to be to me right now.

AFAIK, SLI is the better multi-gpu system, better drivers, better scaling, 1st to combine other manufacturers cards.

 

[NumericalMethods]

I knew they did that. The one thing I don't understand is, how does this not lead to masses of microstutter? I take it crossfire is not alternate frame rendering if this is not a problem?

 

[OCGuy]

Solofly using nV? Shens

 

[solofly]

For a very very long time...

 

[tviceman]

Generally speaking (as in not always, but more often than not) SLI will yield better scaling and overall better compatibility. That said, you cannot mismatch different cards in SLI. So CrossfireX does provide better/more options for future upgrading paths if crossfire is something you can/want to do.

Apoppin managed to CF two 2900's, one 512 bit and the other 256 bit. Maybe one was an XT and the othe a Pro? You'd have to ask him. But yea, CF seems to be fairly flexible but SLI appears to scale somewhat better.

I meant the GPU technology itself.

 

[Patrick Wolf]

So the clocks can't be different on each card in SLI? Say if one's vanilla and the other has a factory OC it will just default both cards to the vanilla speeds?

Correct, for nvidia that is but not for ATI...

AFAIK, SLI is the better multi-gpu system, better drivers, better scaling, 1st to combine other manufacturers cards.

Scaling is debatable, I can see that both scales ver well, but GTX4x0 series scaling is more consistent, even though it sucks more CPU power. Better drivers is also debatable, some nVidia drivers kill videocards and some ATi drivers (10.6) have Crossfire issues. nVidia might be the first to combine different vendors, but you are not able to combine a GTX 285 with a GTX 280, with ATi, you can combine an HD 5830 with an HD 5970, pointless though. Crossfire overall is far less restrictive, can run in any Intel chipset that supports it and Intel's chipsets are far superior than any nVidia chipset currently.

 

[solofly]

nVidia chipsets = Total Junk!

 

[Sheninat0r]

Because nVidia has current-gen chipsets out, right? Oh...

 

[evolucion8]

And your point is? Seems that your knowledge in computer is debatable. nVidia chipsets regardless of their release date, has been notorious with slow performance problems, memory incompatabilities and even heat issues in some cases.
