Has anyone seen this test at Macrumours yet?

Maybe somebody should. It shows a MAC Pro 6,1 giving the new high priced iMac Pro a stomping.

Should be interesting to some.

I've heard that the cards work on iMac Pro, with none of the "screens are black" issues. Or modded kexts. Or "scripts" written by strangers that you need to give Admin privileges.

Again, they "Just Work".

And on MBP 13" nTB and Mini 2014, they "Just Work" with Win 10 and Nvidia 397.31 to allow internal screens to be run from eGPU. No mods, nothing. Just follow boot procedures for the card, and it's already working when you get to desktop. Literally.

Unplug external display, and your internal one is now run by Titan Xp. (Or whatever)

"Big Deal" you say?

Yes, you take a hit for running the video back down the TB3 cable, but now...you can connect a Titan Xp to your Thunderbolt Display. I get at least one email a month from someone peeved that their TB display won't work on MDP port. Don't blame me, blame Apple. But at least in Windows, this now allows you to use that TB display with a powerful GPU instead of the lily-livered one that came in your older Mac.

Or...for those 27" iMac users, here's a chance to run that FAB internal display with a REAL GPU. Could even work on the 5K iMac, I don't know. So Windows Gamers are SET.

So, for the Caveats. To get this same Magic working on 15" MBP I had to leverage additional "gags". I had to take out the RX 460 (via a simple hack) and then enable the Intel iGPU into Windows via an easily available switch on Refind. We may eventually create specific cards for specific machines like this, do the 3 hacks for you. (I'll have to talk to engineering)

End result is same as the Mini and 13" nTB MBP. Timespy went from 7300 on external to 6000 on internal. I don't have the time it would take to run it on the 460.

Since iMac Pro has AMD cards, it is likely that same tricks will work on it, perhaps with some modifications.

But we'll know soon enough.

So, this new functionality requires an Intel iGPU and an Nvidia dGPU or eGPU. This is why it works on the 13" and Mini OOTB with EFI cards. This is why you need to "disappear" the RX 460 (or other dGPU) to make the external eGPU run the internal display on Macs with dGPU. Sadly, this is also why the nMP 6,1 will never run a TB display with a modern card. There is no iGPU in nMP. Certainly not an Intel one.

But, the nMP 6,1 is about to become a viable VR development machine, something it has not been yet. It won't need an iGPU or internal screen for that.

They work on 2015 MBP Retina with AMD dGPU.

Both the eGPU and internal screens work but the internal gets sluggish.

Will do a Win 10 install to see how it works there, my guess is it will need the iGPU tricks to work right.

Next, a 2012 with GT650M.

That's awesome work, you and Netkas always take Mac GPU's to the next level.

Really interesting that you're able to use the internal display.

Can't wait to get my grubby little hands on this. Grin

Thanks !

Looking to start shipping first batch of 1080Tis June 15th.

Barefats has one a test with iMac Pro.

Sadly, he didn't do any multi-1080 or multi Titan tests.
