Not sure what that means but just look at the picture, it has 4 RAM slots. Might mean single and dual channel I guess, dual channel basically means if you have a matching pair of RAM sticks it works faster (2, 1gig sticks for example, if you added a 3rd it would revert to single channel) can't say I've really noticed a difference.
If you look at the picture you can see 4 RAM slots, the red and yellow things.
....and as for Intel nothing being as good as AMD, I don't think you'd find a balanced argument for that at the moment. Intel are quiet a distance in front right now but none of that matters, all thats really important is which one you prefer.
