I Need Help Understanding eGPU

 Share

(eGPU for a Macbook pro mid 2012 13" non-retina) I'm having a problem understanding what exactly is in a eGPU enclosure, for example is it just a PCI-E slot wired to a thunderbolt cable? 

My next question is this: an you just plug a external GPU that is compatible with a macbook if a PCI-E slot was wired to a thunderbolt cable and supplied with external power?

or is there some kind of proprietary circuitboard that does some kind of in-between management?

An eGPU is a graphics processor that resides outside of a computer. It is attached via a high-speed connection, such as Thunderbolt cable, which provides sufficient bandwidth to process graphics in real-time outside the computer.

 

Does that help?

Btw your 2012 MacBook is not compatible with eGPUs since it runs on an older version of Thunderbolt. To use the new eGPU features you must be on a 2016 or newer MacBook Pro

I'm very thankful for you help, and if you could indulge me a little more as i am still trying to learn, (I've had a macbook for the last 10 years of my life, meaning i'm out of touch with this stuff) so when you say "processor" your NOT meaning the graphics CARD correct? you are saying that there is a motherboard in the external case that does a lot of the processing before it reaches the Mac correct?

Thank you for your reply,    Arn't there enclosures out their that run on thunderbolt 1 and or 2, i know they are slower in transfer rates thunderbolt 1 being 10G/s, thunder2 being 20G/s, I thought that you can use a thunderbolt one but you would run into some bottlenecking due to the fact that thunder1 isn't fast enough, or is my understanding mistaken?

Those enclosures exist, but Apple has ended their ability to work since macOS High Sierra. You would need to use a previous version for those older enclosures to work.

Thanks again for the help,  I'm very thankful, I posted this earlier and because I don't know to reply to multiple comments at once, so another poster said this \/ \/ \/  and it left me a little confused. and i was wondering if my interpretation below Max's is correct?

In simplistic terms an egpu is a a graphics card hooked up through USB to a computer.

Though it may not help since this guy did this with Windows 10 ... it is basically a egpu -without the case:

 

In the case of "Processor".

It refers to BOTH:

CPU= Central Processing Unit

GPU= Graphics Processing Unit
