Will Apple egpu work with internal display of the new iMac in future?
This is my question as well. I am hoping that the new iMac will be able to utilize an eGPU to drive the internal display without much modification.
From an AppleInsider article it does not sound like the official apple external GPU development kit will accelerate the internal screen only an external monitor or headset. Not sure about third party eGPUs.
"It should be noted that while external GPUs via Thunderbolt 3 will enable support for virtual reality, the graphics enhancements can also be experienced with an external monitor. Apple's notes to developers make it clear, however, that the External Graphics Development Kit does not accelerate the internal Retina display on an iMac or MacBook Pro."
it will work 100% probably in spring 2018 but with amd cards, its 50-50 to work with nvidia as well
How do you know?
9to5mac explained it, there are a few bugs, but this because its beta, until spring is a lot of time
Its clear Apple will fully support eGPU with any mac that has usb-c/TB3 with amd but i think even with nvidia,if they will still updating the drivers
I'm thinking there will come a time when you will also be able to use Nvidia.
Not in beta at least. I wouldn't get my hopes up.
I don't think even Apple engineers know yet. Official eGPU support is targeted for Spring 2018 -- basically a year from now. An awful lot can change between now and then. Right now in its early implementation, the eGPU apparently hits some sort of a serious bottleneck when it pumps video back into the internal display. Some have called it a "double rendering" of a single screen which I myself don't fully understand, but I think the ultimate effect is that you don't get the full performance boost that you would for an external display.
