For the external GPU route on a mac, does anybody know how fast the bus would need to be? Like could you use two USB-C ports in parallel on the latest and greatest mac or something??
- na85 10y agoThe bandwidths can be found via a quick Google search. You'd need something like 8 usb c ports in parallel, and the CPU overhead would be punitive.
- jolux 10y agoEven with Thunderbolt 3, running at 40Gbps full duplex?
- monocasa 10y agoThat's about equivalent to PCIe 3.0 4x, or PCIe 2.0 8x.
- shurcooL 10y agoWhat about Thunderbolt 3?
- jwatte 10y agoWe tried a Razer Core on a MacBook but it wouldn't work. Works great with the Razer laptops though! (BTW, you can't even buy any Mac with a decent GPU anymore, no matter what the form factor!)
- xt00 10y agoIt seems like the Akitio Thunder 3 would work -- did you try that one? I guess you would need a MBP with thunderbolt 3 then.. so 2016 models from like 3 months ago then?
- nottorp 10y agoYou can't even hackintosh a Mac with a decent GPU any more, since NVidia hasn't put out drivers for their 1xxx cards for OS X.
- netzone 10y agoOh, really? Do they have any plans to?
- nottorp 10y agoIf they are, they're not telling. In theory the nvidia out-of-os x drivers are for people using their cards on the pre trashcan Mac Pros. In practice they allow you to make yourself a decent hackintosh desktop. Or used to. Maybe the 1xxx cards don't work on the old Mac Pros, in which case i don't think nvidia can justify continuing putting out those drivers. Who would this hurt? Apple. Very slowly though. Most people running hackintoshes are opinion leaders wrt to tech stuff, and when they switch to Linux or Windows, Apple will lose more mind share.
- throwaway2048 10y agoNo (recent) offical macs are capable of installing a nvidia PCI card
- nottorp 10y agoYeah but a good bunch of the pre-trashcan Mac Pros are still in service. And those do take PCI Express cards. Apparently NVidia felt it's a market worth serving, since you can still get Sierra drivers from them for anything before the 1xxx series. Okay, the drivers are labeled "for Quadro", but they support basically everything.
- erik 10y agoExternal GPUs are explicitly supported by Thunderbolt 3, and some people have had success with it on TB2 as well. The 4x PCIe 3.0 lanes offer enough bandwidth for most purposes. It's kind of poorly supported on Mac OS though, and the enclosures aren't cheap.

- y_u_no_rust 10y agoIt sounds good but apple makes it a pain, to use an eGPU effectively you need to use windows via bootcamp
- Synaesthesia 10y agoYou're better off building a hackintosh and sticking a huge GPU in there.
