That doesn’t make any sense for user experience right now.  20000 metal compute score sounds good compare to 1080 ti or iris pro. But if you compare it to small upgrade with rx 580/rx5700xt or upcoming big navi cards then it sounds like nothing.

 

I will understand if Apple say that  egpu is not supported during the limited bandwidth in the first generation of arm (m1) macs  or lack of the drivers (that are in work).

 

User should be able to have smooth transition opportunity by using egpu with new macs. Because until there will be  arm mac with amd card inside or apple dgpu/on chip gpu around 40.000 metal score. There is no sense to go for the main machine upgrade.

 

It’s either sticking with your existing egpu setup at home and buying new mac for work and other purposes or upgrading intel mac which makes no future proof sense.

 

Where adding egpu support could make more people to rush with their upgrade and sticking to the new architecture.

I picked up a MacBook Air at the local Best Buy. Thunderbolt device is working except no drivers for third party graphics cards. The macOS version that came with the M1 MacBook Air is 11.0 [20A2411]. There's 11.0.1 update pending install but I don't think that would include the graphics drivers.

Each Thunderbolt port is on its own Thunderbolt Bus. I will gather two NVMe drives to test Thunderbolt connection and see what difference Apple's implementation on these M1 Macs compared to Intel systems.

@itsage, wood woop!

Also just read this in-depth M1 article on Anandtech, which was highly informative and interesting. I look forward to your analysis!

Thanks. The PCIe lanes are there and sufficient, the controller is completely fine too. Only Radeon drivers haven't been ported to ARM yet.

I asked Apple tech support and they confirmed...Apple has made the choice, as a company, to only support their own GPUs going forward on new products, no eGPU support forthcoming, based on my conversation.

The rest is just my opinion so take it as you like or don’t — but this move allows them to remove any security concerns with thunderbolt and DMA attacks and driver problems, and it’s highly unlikely they will be working with AMD on any kind of integrated chips, as they put hitched their wagon to imagination technologies a long time ago for their iOS products, and now for Mac OS based products as well.

M1 Macs still have a TB3 interface so I am not sure how they could remove any eGPU/external PCIe compatibility and still be TB compliant.

The current lack of eGPU support is probably simply more down to ARM driver availability. So, will there ever be ARM drivers for AMD cards? Difficult to tell but it seems Big Sur has code for AMD’s upcoming Navi 21, Navi 22, and Navi 23 GPUs. Could these come in future Apple Silicon Macs or minor revisions of Intel ones?

Ah didn't know Big Sur has preliminary code for those.

Rather than testing with NVMe Thunderbolt 3 drives, I did a full teardown of M1 Mac mini. It comes with two Thunderbolt 4 controllers.

@eightarmedpet, now, I think Intel i7 Mini will be more suitable. I can use egpu as a transition until mbp16' updated.

I want to know what you think.Thanks

 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Yeah I bought a macbook pro 13 inch with M1 a week ago, its funny the egpus are detected in the OS so its not a hardware issue, it may just be a drivers issue with Mac OS for M1 chips.

if EGPU manfactures make there own drivers then I think it will be all good.

@namechu0227, I think I'm swinging towards an i7 too.

I never find streaming constant or a great experience, and that includes in house streaming. Geforce is a horrible mess, Stadia appears limited, and I'm not sure about Shadow as it sounds like an outdated product. But thats just my personal experience....
