Both notebooks come with NVIDIA GeForce GTX 1070, a Skylake Intel Core i7 processor, as well as an optional DDR4 2400MHz memory upgrade.

All new Gigabyte Notebooks coming without Thunderbolt 3 Support! :-(
None of the new Gigabyte Skylake Notebooks with nVidia Pascal Geforce 1060/1070/1080 does supports Thunderbolt 3!
All new Gigabyte Notebooks P35x v6, P37x v6, P55x/w v6, P57x v6 and also the AORUS Series X5 and X7 v6 coming without Thunderbolt 3 support! It's a shame!
So it is not possible to use these notebooks with a Thunderbolt 3 docking station or an external eGPU case!
If notebookcheck makes a review of new notebooks with the USB Type-C connector please add a comment if Thunderbolt 3 is not supported!
