2016 TB3 MBP + Pascal Card 4k video performance

Hi,

I currently have a 2016 13" MBP with TB running an RX480 through a Sonnet III-D with a TB3-TB2 adapter on 10.12.3. I have a 1080 that's ready to go but I was wondering whether people who already have a TB3 MacBook with a Pascal card set up can play 4k video without lag?

 

The first setup I had I have a Titan X (Maxwell) and 4k video was very laggy, even when not connected to the eGPU and the NVIDIA driver disabled. This was only remedied by using an AMD GPU instead.

 

I would try this myself but the problem is that 10.12.4 firmware breaks the RX480 eGPU setup and there is no way to revert back to the current setup which I have, effectively "bricking" my eGPU setup.

 

So if anyone with 10.12.4 with a TB3 Mac and an NVIDIA (Preferably Pascal) Card can try playing a 4k video either through Photos or Quicktime (There are loads of 4k video samples with a quick Google search), it would be very much appreciated!

4k uncompressed video @ 60Hz requires 14Gbps of eGPU bandwidth which your TB2 enclosure won't be able to provide. SO firstly upgrade to a TB3 enclosure to gain 22Gbps of bandwidth.

Attach that TB3 enclosure to the left side 22Gbps TB3 port rather than your right side 16Gbps TB3 port on the 13" MBPtb.

Also be mindful of the TB3-PCH architecture of your system where the  x4 3.0 DMI can be bottlenecked under concurrent SSD+TB3+USB activity. A 15" MBP plaform's architecture is superior there as is not affected. More details at https://egpu.io/forums/builds/late-2016-15-macbook-pro-gtx-1080-ti32gbps-tb3-mantiz-venus-macos-itsage/

Thanks for the reply!

 

The thing is though I had no problems playing and editing the compressed 4k video shot from iPhones, etc. and even in-game recordings with an RX480 installed and even with my 2013 MBP and 780Ti setup that I used to have ages ago so I know that TB2 is not the problem. 

ikir also mentioned a few months back that his NVIDIA card ran like "dog poop" when trying to play back a 4k video downloaded from the internet. This was with an Akitio Node.

 

The problem is when I tried back then to play the same compressed files with an NVIDIA card (Titan X Maxwell) plugged in to the TB3 MBP. Even 1080p60 struggled a bit. Youtube 4k sometimes struggled as well! As mentioned, it was only rectified by using an AMD card in the eGPU instead.

I just need someone with a TB3 MBP+NVIDIA Pascal card to test this and see whether NVIDIA's progression with their drivers is far enough that this problem has somehow been rectified. My suspicion is somewhere in compatibility with Metal-accelerated apps.

My T430s (hooked up to my TV) has no problems playing YouTube 4K videos with a 1050Ti, as well as 4K footage from my phone. That is on a TB1 setup. These are 30fps videos, not 60fps, though.

Give your Node Pro a second Thunderbolt3 controller for reliable peripherals by re-using a TB3 dock (~50$).

The thing is though it still doesn't explain why 4k videos that I've shot myself using my iPhone lagged on an NVIDIA eGPU but played without problems on an AMD eGPU that was less powerful! I still had acceleration as I had a noticeable FPS increase in games!

 

I just wanted someone with exactly a TB3 MacBook and an NVIDIA eGPU on macOS 10.12.4 to test a 4k video 🙁

So I guess I just jumped in and tried it anyway. 4k still ran horribly. It worked fine on my 2013 MBP for some reason though.

 

Time to try to get my 2016 to run on the RX480 now :/

I confirm 4K video playback is terrible with Pascal card...

i hope Nvidia fix it soon.

Thanks for that! Unfortunately 4k video was also horrible even when the eGPU wasn't plugged in, so I just uninstalled the lot and just placed back my RX 480... I was so looking forward to getting a 1080 :/

Can you confirm with Radeon RX 4k is ok?
