Hasn't ATI said that it increases power consumption and heat in exchange for a negligible performance improvement?

Probably something wrong with it. I'd like to think that they're biding their. Time but that doesn't make a lick of sense. Right now they've got nvidia on the ropes outside of physx and cuda. Both of which are in trouble with ati's new techs and the looming dx11. Why wouldn't they just enable it and destroy nv's marketshare even more

power consumption was around single digit so power consumption wan't a reason for it.it didn't make any performance improvement was the official line dunno if they were trying to hold it back though.

As for heat and power concerns, that's hardly the case...the interconnect is pretty much an extra PCIE2.0 link. The power draw for that is in the realm of a few watts at most. The only reason for which it's not enabled currently is, as I've already mentioned, that it does not significantly impact performance ... and if you're not using something there's no point in enabling it.

i don't think 4870X2 owners care if ati thinks the performance boost is negligible, because they want to test and see for themselves.

Or the 4870X2 is already so fast now they'll only unlock it when nVidia releases something competitive.

Would you be so kind as to shed some more light on this "direct connect" ?
