Thunderbolt on a laptop?

I have a relatively modern laptop, with pretty much every connection. Only one is missing, the Thunderbolt 3. Instead, a usb c 2.0 is installed. Is there a possibility to connect a gpu anyway?

External GPUs can usually only be connected to PCIe-supported connections such as Thunderbolt, USB 3.x or PCMCIA.

USB 2.x is not directly PCIe-supported.

So as I said, have every connection except Thunderbolt 3

If your notebook had a USB 3.1 Gen.2 (10 Gbit / s), then it would also be possible.

Note, however, that such external graphics solutions would cost several 100 euro, since in addition to the actual PCIe graphics card, an external housing with its own power supply would then be necessary.

You could better sell your old notebook and buy a book with a better internal graphics solution.

So I have a usb 3.1 Gen 2 10 gbits, but with almost every case it says that it is too slow.

Of course, this option is very slow compared to a real PCIe connection, but Thunderbolt can't keep up here either.

For comparison:

- PCIe 2.0 already creates 500 Mbyte / s (gross) of data transmission per lane

- PCIe 3.0 even brings about 965 to 985 Mbyte / s per lane

----------------------

- PCIe 3.1 Gen.2 brings gross 10 Gbit / s = 1.25 Gbyte / s

- Thunderbolt 3 brings gross 40 Gbit / s = 5.0 Gbyte / s

(calculated here in decimal instead of binary)

Therefore again: as a rule, in monetary terms and in terms of usage, it is more worthwhile to replace the notebook with higher demands on graphics performance than to look for external solutions for several 100 euro plus graphics card.

Which notebook do you have exactly?

I have the Asus Rog GL502VS, but an i7 7700HQ is installed instead of i7 6700hQ. 16 gb RAM and a 1070 OC 8gb are installed.

Then what do you want with an external graphics card?

For external cards the size of a GTX 1070 (and up), even the Thunderbolt 3 interface should be a limiting factor.
