EVGA Pro SLI Bridges. Faster than ordinary SLI cables?

Meh, it's clearly good for publicity. Although if it ends up on an actual product page where they are being sold then it's not funny. Tactical troll EVGA, I see your play, I really don't mind a company that can have banter like that.

I guess that's just what you have to do when you aren't ROG and fanboys be cray for your swag before you've announced it.

Hmm, thinking about it I have always wondered why adding another, exactly the same card, never gives a 100% performance improvement over one card. There must be a bottleneck somewhere, could be either hardware or software related.

I very much doubt it's the SLI bridge, but I'd gladly be proven wrong in this case. If not though; EVGA, what are you even doing.

Bottleneck isn't the bridge. It's currently API's that are being used and then by that it steams out to other software/engine issues. A lot of the scaling is due to the fact that the CPUs send out data to the GPUs in a long single queue and the GPUs buffer must decide which data needs to be processed first. So it's just a case of throwing a big bucket of crap into a tiny hole. Then on top of that the CPU must also decide what bucket of crap to throw at the 2nd GPU. Process just repeats. Now some games scale very well and devs actually took the time to get it working as efficiently as they could so kudos to them. Though generally as we have seen on many games is that bad scaling. Pretty sure it's why most SLI/Crossfire configs don't improve minimum frames much(reasons stated already) but the max's increase much more during those less intensive parts of the game.

SPS will probably say i'm wrong and got something confused. But basically that's how i understand it from trying to learn on my own.
