eGPU Thunderbolt 3 to 2?

Recommended Posts

Posted · Original PosterOP

Hello all, this is TheJSTeam, and I am thinking about getting an eGPU for my 2012 Macbook Pro, which has Thunderbolt 1, and I was wondering if I could buy a thunderbolt 3 enclosure, and use a thunderbolt 3 to 1 adapter. Would this work? Thanks!

You can use older thunderbolt 2 adapters and they will work, but you will have significant performance loss as the thunderbolt 1 connection only allows 10GB/s. 

What GPU are you planning on putting in it? and do you planning on using an external GPU or having the video passed back to the laptop? I remember an old graph that showed the falloff of older GPUs.

I am planning in putting in a 1050 TI 4gb (but can get a better one if needed) and planning on having the video passed back to the laptop.

Take a look thought this thread, Specifically look at the performance of a GPU on TB1, AND look at how much more you loose passing the GPU back to the internal display.
