The technology uses both displayport and pci-express protocols - meaning most likely that we will be seeing PCI-express (more likely 8x, but maybe 16x) add-on cards to allow any system to add this connection type.
Now, my question? Will it be compatible with the Displayport connections on current-generation graphics cards? |
1) The Thunderbolt controller connects to the PCH via a 4x PCI-E interface which means 8x / 16x add in cards would be pointless.
2) No. Thunderbolt requires a signal to be sent from origin controller to destination controller. That means if a graphics card doesn't have a TB licensed chip, it will not be compatible with TB products.
