- hendersoon 10y agoInteresting-- I was not aware of that! That's the same bandwidth as TB2, which will add another 10% performance penalty versus a native 16-lane PCIe gen3 slot, for a total of 20% performance lost. Still completely workable.
- kingosticks 10y agoNor was I until I started reading around this topic earlier. It's certainly still workable but just worth keeping in mind before anyone springs extra £££ for TB3 and the latest crazy-powerful GPU.
