The small pinky spike sized fragment you see up there, inside the immature square, is roughly of course the coordinator fragment is to new MacBook Pro's Thunderbolt port. The chip, and its juicy thermal gum topping, were found inside the new MacBooks by the teardown experts at iFixit.
The Thunderbolt (nee Light Peak) coordinator IC is what enables it to work its multi-protocol, daisy-chaining magic. Without that fragment to routine the sequence information purgation by the copper, Thunderbolt would be small more than a reticent wire.
Other than Thunderbolt and upgrades to the CPU and graphics hardware, the new MacBooks are roughly unvaried from the formerly incarnation. The battery is the same 77.5 watt-hour model as before, and the box is probably identical. Changes have been done to the wireless card right away has 4 antennas instead of three, and the RAM is right away the same as that used in final year's 21.5 and 27 in. iMacs. There is moreover lots of thermal gum dirty around in there, that suggests that things are running hotter than before.
As ever, head to iFixit to see the courage if the new MBP in explicit, closeup detail, and wonder at only how couple of tools go in to this thing.
