A correction: Thunderbolt 2 can go up to 20Gbits/s not 20GBytes/s. Thunderbolt uses a 4x PCI-E 2.0 connection. Things like graphics cards use 16x PCI-E 3.0 at

Things like graphics cards use 16x PCI-E 3.0 at this point which is 128Gbits/s.
- kbuck 13y agoActually, a 16x PCIe 3.0 slot can do ~128Gbit/s each way - ~256Gbit/s in total[1]. [1]: http://www.pcisig.com/news_room/faqs/pcie3.0_faq/#EQ3 http://www.pcisig.com/news_room/faqs/pcie3.0_faq/#EQ3
