DisplayPort isn't 17Gbps, it's rated between 1.62Gbps and 2.7Gbps. Just like you mention about Thunderbolt, the theorethical maximum for DisplayPort is 17Gbps, not the actual throughput for devices that are out right now.
The actual throughput for the Thunderbolt port on new MacBooks is well above what the DisplayPort on the older models was.

- ugh 16y agoDidn’t Intel even say that those 10Gbps are real numbers, not theoretical?
- bryanlarsen 16y agoDisplayPort handles 2560x1600 screens just fine, and that requires 6gbps, (2560 x 1600 x 24bits/pixel x 60frames/second = 6Gbps) so I'm not sure where you get your numbers from. 3 Gbps is required to handle full HD, and DisplayPort obviously handles that. Unless you're talking gigaBYTES per second. 2.7GBps is more than 17Gbps, so your numbers are even higher than mine.
- radicaldreamer 16y agoSure, but that's because you're using 4 channels to get there and it's unidirectional. Thunderbolt is 10 Gbps per channel, so actually up to 40 Gbps if there were 4 channels available (there are only 2 shipping on the MacBooks, hence the 10Gbps bi-directional rating).
