PCI Express 3.0 is 1GB/s aka 8Gb/s per lane, you seem to have got confused between GB/s and Gb/s. Three lanes would give you more than you need for a new thunderbolt port.
Also if you take x79 which is a consumer platform it has 40 PCI Express 3.0 lanes which would be enough for 16 of the new thunderbolt ports.
- wtallis 14y agoX79/LGA2011 is way too expensive to be considered as a mainstream option in the consumer marketplace, and isn't even an automatic choice when shopping for a workstation (since the Xeon E3s are so cheap). On LGA1155, the connection between the CPU and GPU is now PCIe 3.0, but the connection to the chipset and other peripherals is still running at PCIe 2.0 speeds and is only 4 lanes wide. Unless you have a motherboard that is specifically designed to rob PCIe lanes from the GPU, all USB 3.0 and SATA 3 ports and gigE ports are sharing that 20Gbps link from chipset to CPU.
