Hello.
I've got 2 TB3 ports on my laptop. Does they share bandwith? I want to connect egpu with R43SG and charger, ssd, eathernet, keyboard, mouse for 2nd port.

@wg824tz, 7390 uses 8th gen CPU, so Thunderbolt controller is discrete, not integrated, so the two TB3 ports have a limit of ≈ 2800 MB/s for PCIe data but the computer is usually not transmitting to both at the same time so it doesn't matter.

It 7390 2in1, so it's on i7 1065g7 (4 cores) and according to Intel their newer CPU i7 1065G7 have thunderbolt 3 controller integrated. So, can i transmit data to both at the same time?

@wg824tz,

The 7390 2-in-1 has 8th gen.

The XPS 2-in-1 has 10th gen.

If you have 10th gen, then both Thunderbolt ports should have full performance all the time.

I don't think it's a problem either way.
