Re: Does This Kill The Mac Pro?

[Jeremy Garchow] "Per channel. So, it's 20 Gb total throughput, as far as I understand it anyway."

yes and no. Yes, it is technically sending 20 Gb total each way, but you can't use all of that for any one use.

Thunderbolt had Display Port and PCIe in the same cable, but they're two separate systems. You can't have anymore then 10Gb of each. So calling it 20Gb is incorrect cause if I want to send data X from point A to B, 10Gb is how fast it'll get there. There's no way for it to use both channels.

At least that's my understanding of the connection.

There is the possibility that PCIe over both channels would be possibile, but in that setup, there would be no Display Port signal.
