A support technician told Ars that Apple's cable is a "smart" cable that "has firmware in it. Intel confirmed that Thunderbolt requires specific Thunderbolt cables. Apple didn't respond to our requests for further information about the "firmware in the cable," but an EETimes article from earlier this year noted that in addition to having different electrical characteristics from Mini DisplayPort, Thunderbolt also uses active cabling to achieve full duplex 10Gbps transmission. A source within the telecom industry explained to Ars that active cables are commonly used at data rates above 5Gbps.

After picking up the new wonder-cable and digging into its "suspicious" looking sturdy plastic sleeve, iFixit's Miroslav Djuric was confronted with a lot of hefty metal shielding. One soldering iron and a bit of chopping later and he was in. So what's inside: The cable contains 12 individual chips, almost as many chips as the Smart Cover has magnets , plus a small handful of sundry resistors and other electronic-y type bits.
The main brains seem to be in the two Gennum GN chips, one in each end. So that, I'd guess, is where your money is going. I'm not saying there isn't a decent profit margin on the Thunderbolt cable — there surely is — but at least you're getting something other than copper strands and plastic for your cash. The 12 chips inside Apple's Thunderbolt cable might justify its high, high price.
